    Abstract Actinium-225 (Ac-225) is a promising alpha emitter for radionuclide therapy, with clinical applications expected to start soon. As Ac-225 is introduced for therapeutic use, imaging of Ac-225 and its daughter radionuclides could address challenges such as monitoring radionuclide injection and detecting contamination in clinical settings. While a small field-of-view (FOV) gamma camera could potentially be useful in such scenarios, its efficacy has not yet been thoroughly evaluated. In this study, we assessed the feasibility of using a small FOV gamma camera for imaging Ac-225 and its daughter radionuclides. The gamma camera employed consists of a 10 mm-thick GAGG pixel scintillator block optically coupled to a position-sensitive photomultiplier tube (PSPMT). It is housed within a 2 cm-thick tungsten shield, with a 1 mm diameter pinhole collimator mounted at the front. To image gamma photons from Ac-225 and its daughter radionuclides, we measured 440 keV gamma photons from Bi-213 and 218 keV gamma photons from Fr-221 at varying distances. Using an 8 MBq solution of Ac-225 and its daughter radionuclides positioned 10 cm from the camera, imaging was achieved less than 1 minute, yielding a spatial resolution of approximately 4 mm full width at half maximum (FWHM) and a sensitivity of 1.6 × 10-6. We conclude that imaging Ac-225 and its daughter radionuclides is feasible with a small FOV gamma camera, as well as improved sensitivity would enhance its utility for applications such as monitoring radionuclide injections and detecting contamination in clinical environments.

    Abstract Actinium-225 (Ac-225) is a promising alpha emitter for radionuclide therapy due to its remarkable clinical efficacy in treating prostate cancer. The daughter radionuclides of Ac-225 emit beta particles with energies exceeding the Cherenkov-light threshold, making it possible to image them by detecting Cherenkov light. However, the performance of Cherenkov-light imaging for Ac-225's daughter radionuclides has not been assessed through experiments or simulations. To address this, we evaluated the performance of Cherenkov-light imaging for the daughter radionuclides of Ac-225 using both phantom experiments and simulations. A solution of Ac-225 and its daughter radionuclides was placed in an acrylic rod phantom, and Cherenkov-light images were acquired using a high-sensitivity CCD camera. We could obtain clear image of Cherenkov-light and the resulting images demonstrated a spatial resolution of less than 1 mm full width at half maximum (FWHM). Monte Carlo simulations indicated that the theoretical spatial resolution of Cherenkov light emitted from daughter radionuclides of Ac-225 was ∼0.026 mm FWHM, significantly finer than the experimental results, suggesting the blurring the experimental image. In conclusion, Cherenkov-light imaging of Ac-225's daughter radionuclides provides high spatial resolution and shows potential for applications requiring precise distribution measurement of Ac-225 and its daughter radionuclides.

    Abstract The purpose of this study is to evaluate the feasibility of monitoring therapeutic carbon-ion beams by measuring prompt X-rays in the clinical application of head treatment. Specifically, we investigated the ability to identify 2 cm differences in beam arrival depth in a head phantom using secondary electron bremsstrahlung. First, a Monte Carlo simulation was conducted. A head phantom was positioned at the center of the simulation space, surrounded by 24 X-ray cameras, and three carbon-ion beams were irradiated. Next, an experimental study was performed using the same beam configuration, with X-ray cameras acquiring images from parietal and temporal-head directions. Simulation results indicated that beam images could be acquired over a wide range of ±135 degrees from the parietal direction, distinguishing 1.8 cm depth differences. Experimentally obtained images were consistent with simulations. These findings suggest that prompt X-ray imaging is a promising tool for monitoring therapeutic carbon-ion beams.

    Abstract In targeted alpha-particle therapy, actinium-225 (Ac-225) has emerged as a radionuclide of potential, driving extensive efforts to develop innovative radiopharmaceuticals. High-resolution imaging of alpha particles is required for precisely detecting alpha-emitting radionuclides in cellular environments and small organs. Here, we report real-time trajectory imaging of alpha particles emitted by Ac-225 and its daughter radionuclides, utilizing an alpha particle trajectory imaging system. This system incorporates a magnification unit, a cooled electron-multiplying charge-coupled device (EM-CCD) camera, and a Ce-doped Gd3Al2Ga3O12 (GAGG) scintillator. Alpha particles were projected onto the GAGG scintillator, producing magnified images that were captured at 100 ms intervals. We successfully tracked particle trajectories with varying lengths and intensities for 4 different alpha particles emitted from Ac-225 and its daughter radionuclides with a spatial resolution of 1.0 μm. Notably, we achieved the imaging of sequentially emitted trajectories from Fr-221 and its decay product At-217, characterized by short decay intervals, along with the extended trajectories of high-energy alpha particles emitted by Po-213. These results demonstrate that high-resolution trajectory imaging, integrated with temporal and energy information, offers profound insights into the real-time behavior of Ac-225 and its daughter radionuclides within living cells or tissue sections, thereby driving advancements in targeted alpha-particle therapy.

    Prompt gammas imaging (PGI) is a promising method for observing a beam's shape and estimating the range of the beam from outside a subject. However 2-dimensional images of prompt gammas (PGs) during irradiation of protons were still difficult to measure. To achieve PGI, we developed a new gamma camera and imaged PGs while irradiating a phantom by proton beams. We also simultaneously measured prompt X-ray (PX) images with an X-ray camera from opposed direction and compared the images. The developed gamma camera uses a 10 mm thick GAGG block optically coupled to a flat panel photomultiplier tube (FP-PMT), and it is contained in a 20 mm thick tungsten container with a pinhole collimator attached. A poly-methyl-methacrylate (PMMA) block was irradiated by proton beams with total number of the protons similar to the clinical level, and the gamma camera imaged PGs and X-ray camera imaged PXs simultaneously. For all of the tested beams, we could measure the beam shapes of the PGs and the PXs and the ranges could also be estimated from the images. For both PG and PX images, time sequential images and accumulated images could be derived. We confirmed that the PGI using our developed gamma camera, as well as PXI, is promising for beam imaging and range estimation in proton therapy.

    Abstract Scintillator-based X-ray imaging detectors are pivotal in numerous scientific and practical domains, including medical imaging, food and device inspection, and security monitoring. Recent advancements have spurred interest in 4D X-ray imaging using synchrotron radiation, necessitating higher temporal resolutions. Consequently, this places stringent demands on X-ray detector technology, especially when X-ray energy exceeds 20 keV. The selection of a suitable scintillator material is crucial for achieving optimal timing resolution, yet it poses a significant challenge in dynamic X-ray imaging. This study delves into the optimization of scintillator properties and their impact on spatial resolution and light output, elucidating the performance of Ce-doped Gd3Ga3Al2O12 (GAGG:Ce) scintillators for X-ray imaging applications. We developed a micro X-ray imaging detector using a 100 μm-thick GAGG:Ce scintillator plate and conducted X-ray imaging tests at the Aichi SR facility. The results demonstrated that the resolution, quantified as the chart slit width at a contrast transfer function (CTF) value of 10%, reached 2 ∼ 3 μm with a 4× lens, 0.52 μm± 0.03 μm with a 20× lens, and 0.42 μm± 0.01 μm with a 40× lens. Although the results of this study did not achieve a spatial resolution nearing the effective pixel size of the 40× lens, the text also elucidates the underlying reasons for this limitation. Furthermore, we compared the X-ray sensitivity of our GAGG:Ce scintillator plate with that of a commercial LuAG:Ce scintillator, revealing an approximately 1.5-fold increase in light output. As a demonstration, transmission images of dried small fish were captured using the GAGG:Ce scintillator plate and the developed X-ray imaging system. These findings highlight the potential of the X-ray imaging detector devised in this study for future generations of X-ray imaging applications.

    Abstract We report the growth of bulk β-Ga2O3 crystals based on crystal pulling from a melt using a cold container without employing a precious-metal crucible. Our approach, named oxide crystal growth from cold crucible (OCCC), is a fusion between the skull-melting and Czochralski methods. The absence of an expensive precious-metal crucible makes this a cost-effective crystal growth method, which is a critical factor in the semiconductor industry. An original construction 0.4–0.5 MHz SiC MOSFET transistor generator with power up to 35 kW was used to successfully grow bulk β-Ga2O3 crystals with diameters up to 46 mm. Also, an original diameter control system by generator frequency change was applied. In this preliminary study, the full width at half maximum of the X-ray rocking curve from the obtained β-Ga2O3 crystals with diameters ≤ 46 mm was comparable to those of β-Ga2O3 produced by edge-defined film fed growth. Moreover, as expected, the purity of the obtained crystals was high because only raw material-derived impurities were detected, and contamination from the process, such as insulation and noble metals, was below the detection limit. Our results indicate that the OCCC technique can be used to produce high-purity bulk β-Ga2O3 single crystalline substrate.

    Aluminum garnets display exceptional adaptability in incorporating mismatching elements, thereby facilitating the synthesis of novel materials with tailored properties. This study explored Ce3+-doped Tb3Al5-xScxO12 crystals (where x ranges from 0.5 to 3.0), revealing a novel approach to control luminescence and photoconversion through atomic size mismatch engineering. Raman spectroscopy confirmed the coexistence of garnet and perovskite phases, with Sc substitution significantly influencing the garnet lattice and induced A1g mode softening up to Sc concentration x = 2.0. The Sc atoms controlled sub-eutectic inclusion formation, creating efficient light scattering centers and unveiling a compositional threshold for octahedral site saturation. This modulation enabled the control of energy transfer dynamics between Ce3+ and Tb3+ ions, enhancing luminescence and mitigating quenching. The Sc admixing process regulated luminous efficacy (LE), color rendering index (CRI), and correlated color temperature (CCT), with adjustments in CRI from 68 to 84 and CCT from 3545 K to 12,958 K. The Ce3+-doped Tb3Al5-xScxO12 crystal (where x = 2.0) achieved the highest LE of 114.6 lm/W and emitted light at a CCT of 4942 K, similar to daylight white. This approach enables the design and development of functional materials with tailored optical properties applicable to lighting technology, persistent phosphors, scintillators, and storage phosphors.

    Abstract An imaging technique utilizing a scintillator plate in conjunction with a magnifying unit and a cooled electron multiplying charge-coupled device (EM-CCD) camera shows promise for capturing high-resolution trajectory images. Nevertheless, in the 2-dimensional trajectory images, the incident directions of the alpha particles entering the scintillator plate remained unknown due to the line-shaped trajectories. To elucidate the incident directions in our trajectory images, we conducted experiments capturing trajectory images of alpha particles under off-focus conditions. To capture off-focus images of alpha particles, we systematically varied the distance between the GAGG plate and the lens during imaging using an americium-241 (Am-241) source. Through images obtained at different distances between the GAGG plate and the lens, we successfully acquired trajectory images with varying degrees of off-focus, revealing that trajectory images focused on the upper surface of the GAGG plate exhibited blurred and wider trajectories in the deeper regions, making the incident directions of the alpha particles evident. We conclude that the proposed off-focus method for trajectory imaging of alpha particles holds promise for estimating the incident directions in the trajectory images.

    Abstract It is known that scintillators exhibit non-proportional behavior between light output and the energy of gamma photons or beta particles. However, the non-proportionality between light output in scintillators and the energy of alpha particles has not been extensively measured, likely due to the challenges associated with preparing alpha particles with varying energies. To address this issue, we propose a novel method to modulate the energy of alpha particles using an americium-241 (Am-241) source covered with different numbers of Mylar films. By irradiating various scintillators, including GAGG, GGAG, YAP(Ce), and plastic scintillator, with alpha particles of different energies, we measured and evaluated the non-proportional response of these scintillators. We then compared the measured response as a function of incident energy to a simulation, which assumes a proportional response to evaluate the non-proportionality. For all the scintillators tested, non-proportionality was observed; the light output per MeV at 1.8 MeV ranged from 0.60 to 0.81 of the values observed at 5.2 MeV. The non-proportional response was largest for plastic scintillator (0.60) and smallest for GAGG (0.81). We conclude that the proposed method could be an efficient means of measuring the non-proportionality of scintillators between light output and alpha particle energies

    Abstract Objective. Prompt gamma photon, prompt x-ray, and induced positron imaging are possible methods for observing a proton beam’s shape from outside the subject. However, since these three types of images have not been measured simultaneously nor compared using the same subject, their advantages and disadvantages remain unknown for imaging beam shapes in therapy. To clarify these points, we developed a triple-imaging-modality system to simultaneously measure prompt gamma photons, prompt x-rays, and induced positrons during proton beam irradiation to a phantom. Approach. The developed triple-imaging-modality system consists of a gamma camera, an x-ray camera, and a dual-head positron emission tomography (PET) system. During 80 MeV proton beam irradiation to a polymethyl methacrylate (PMMA) phantom, imaging of prompt gamma photons was conducted by the developed gamma camera from one side of the phantom. Imaging of prompt x-rays was conducted by the developed x-ray camera from the other side. Induced positrons were measured by the developed dual-head PET system set on the upper and lower sides of the phantom. Main results. With the proposed triple-imaging-modality system, we could simultaneously image the prompt gamma photons and prompt x-rays during proton beam irradiation. Induced positron distributions could be measured after the irradiation by the PET system and the gamma camera. Among these imaging modalities, image quality was the best for the induced positrons measured by PET. The estimated ranges were actually similar to those imaged with prompt gamma photons, prompt x-rays and induced positrons measured by PET. Significance. The developed triple-imaging-modality system made possible to simultaneously measure the three different beam images. The system will contribute to increasing the data available for imaging in therapy and will contribute to better estimating the shapes or ranges of proton beam.

    Abstract Uncovering neutrinoless double beta decay (0ν2β) is crucial for confirming neutrinos’ Majorana characteristics. The decay rate of 0νββ is theoretically uncertain, influenced by nuclear matrix elements that vary across nuclides. To reduce this uncertainty, precise measurement of the half-life of neutrino-emitting double beta decay (2ν2β) in different nuclides is essential. We have launched the PIKACHU (Pure Inorganic scintillator experiment in KAmioka for CHallenging Underground sciences) project to fabricate high-purity Ce-doped Gd3Ga3Al2O12 (GAGG) single crystals and use them to study the double beta decay of 160Gd. Predictions from two theoretical models on nuclear matrix element calculations for 2ν2β in 160Gd show a significant discrepancy in estimated half-lives, differing by approximately an order of magnitude. If the lower half-life estimation holds true, detecting 2ν2β in 160Gd could be achievable with a sensitivity enhancement slightly more than an order of magnitude compared to prior investigations using Ce-doped Gd2SiO5 (GSO) crystal. We have successfully developed GAGG crystals with purity levels surpassing previous standards through refined purification and selection of raw materials. Our experiments with these crystals indicate the feasibility of reaching sensitivities exceeding those of earlier studies. This paper discusses the ongoing development and scintillator performance evaluation of high-purity GAGG crystals, along with the anticipated future prospects of the PIKACHU experiment.

    Abstract The growth of Er-doped La2Hf2O7 (LHO:Er) single crystals with a high mp of 2413 °C was achieved by the melt-growth method using a tungsten (W) crucible. Polished LHO:Er specimens were obtained from the as-grown crystals. The full width at half maximum of the X-ray Rocking curve on the (222) diffraction peak was 599 arcsec, and the crystals have relatively low crystallinity. The photoluminescence spectra of the polished LHO:Er specimen showed emission peaks originating from the Er3+ ions in both the visible and IR wavelength ranges. It also exhibited scintillation light under X-ray irradiation.

    T2 relaxation time in magnetic resonance imaging (MRI), which is determined by magnetic dipole interactions, has been employed as a parameter for tumor detection. However, owing to the lack of MRI detection sensitivity, nuclear medicine imaging is currently the basic option for tracking low concentrations of chemical probes. Previous studies utilizing cascade radionuclides have focused on the relaxation due to electric quadrupole interactions. However, magnetic dipole interactions, which are crucial in MRI, remains to be elucidated. In this study, we determined the magnetic relaxation rate by using 111In, a cascade radionuclide used in clinical single-photon emission computed tomography (SPECT) scans. As the angle between the gamma rays from the nuclei is affected by the electrical and magnetic interactions acting on the nuclei, we measured the angular correlation ratio by using eight gadolinium gallium garnet (GAGG) multi-pixel photon counter (MPPC) 8 × 8 array detectors and extracted the magnetic relaxation rate. Consequently, we obtained a rate that increased with the Fe concentration, similar to the T2 relaxation rate, although it was influenced by the inhomogeneity of the external magnetic field. This study utilized low concentrations of the liquid-state radionuclide, which is commonly used in clinical nuclear medicine imaging scans and is expected to provide much higher sensitivity and more selective detection of tumors than conventional MRI.

    Abstract An imaging method that utilizes a scintillator plate combined with a magnifying unit and a cooled electron multiplying charge-coupled device (EM-CCD) camera shows promise for obtaining high-resolution trajectory images. However, it is not yet clear whether the ranges of the trajectory images change with the energy of the alpha particles. Additionally, it remains unclear whether the intensity of the trajectory images is affected by the energy of the alpha particles. To address these questions in our trajectory imaging research, we conducted experiments to capture trajectory images of alpha particles with varying energy levels. To generate alpha particles with different energies, we modulated the energy using an americium-241 (Am-241) source covered with varying numbers of Mylar films. With this alpha source and imaging system, we successfully captured trajectory images with different alpha particle energies and were able to assess the ranges and intensities of these trajectories at various energy levels. The estimated ranges from the measured images with different alpha particle energies closely matched the results obtained through simulations. However, it's worth noting that the light output, as evaluated for the measured trajectory images, was slightly lower than the simulated results at lower energy levels probably due to the non-proportionality of the GAGG plate with respect to alpha particle energies.

    Abstract High-resolution and real-time imaging of the trajectories of alpha particles is desired in nuclear medicine and nuclear engineering. Although an imaging method using a scintillator plate combined with a magnifying unit and a cooled electron multiplying charge-coupled device (EM-CCD) camera is a possible method of obtaining high-resolution trajectory images, the spatial resolution of the system is limited to ∼2 μm. To overcome the spatial resolution limitations of this method on trajectory imaging, we used a cooled complementally metal oxide (CMOS) camera in which the sensor had a much larger number of pixels, which were also smaller. Using the CMOS camera based imaging system, we could measure the trajectories of alpha particles in real time with the spatial resolution of 0.34 μm FWHM. With smoothing of the images to reduce image noise, spatial resolution was still kept to less than 0.75 μm. We conclude that this CMOS camera-based alpha-particle trajectory-imaging system is promising for alpha-particle or other particles imaging where ultrahigh spatial resolution is required.

    Abstract It is known that a lithium-6 (6Li) absorbs a neutron and is divided into a triton and an alpha particle. However, the trajectories of the produced tritons have not yet been imaged in real time and high resolution. We developed an ultrahigh-resolution imaging system that can clearly observe the trajectories of neutron induced particles in real time. The developed system is based on a magnifying unit and a cooled electron multiplying charge-coupled device (EM-CCD) camera combined with a 6Li plate and a Ce-doped Gd3Al2Ga3O12(GAGG) scintillator plate. Neutrons from a californium-252 (252Cf) source were irradiated to the 6Li plate, which produced tritons and alpha particles. The produced tritons or alpha particles entered the GAGG plate and produced scintillation light along the trajectories. The scintillation trajectories were magnified by the unit, light intensified, and imaged by the EM-CCD camera. Using our system, we could measure the elongated trajectory images of the particles in real time. Most of these trajectories had Bragg peak like shapes in the images. The average range was 15 μm and the width was 4.6 μm FWHM. From the ranges we estimated, we found that these trajectories could be attributed to the induced tritons. Consequently, the developed real time imaging system is promising for research on the ultrahigh resolution imaging of neutron produced particles.

    Prompt x-ray imaging is a promising method for observing the beam shape from outside a subject. However, its distribution is different from dose distribution, and thus a comparison with the dose is required. Meanwhile, luminescence imaging of water is a possible method for imaging the dose distribution. Consequently, we performed simultaneous imaging of luminescence and prompt x-rays during irradiation by proton beams to compare the distributions between these two different imaging methods. Optical imaging of water was conducted with spot-scanning proton beams at clinical dose level during irradiation to a fluorescein (FS) water phantom set in a black box. Prompt x-ray imaging was also conducted simultaneously from outside the black box using a developed x-ray camera during proton beam irradiation to the phantom. We measured images of the luminescence of FS water and prompt x-rays for various types of proton beams, including pencil beams, spread-out Bragg peak (SOBP) beams, and clinically used therapy beams. After the imaging, ranges were estimated from FS water and prompt x-rays and compared with those calculated with a treatment planning system (TPS). We could measure the prompt x-ray and FS water images simultaneously for all types of proton beams. The ranges estimated from the FS water and those calculated with the TPS closely matched, within a difference of several mm. Similar range difference was found between the results estimated from prompt x-ray images and those calculated with the TPS. We confirmed that the simultaneous imaging of luminescence and prompt x-rays were possible during irradiation with spot-scanning proton beams at a clinical dose level. This method can be applied to range estimation as well as comparison with the dose for prompt x-ray imaging or other imaging methods used in therapy with various types of proton beams at a clinical dose level.

    Abstract High-resolution imaging of neutron induced particles is required in such methods as neutron radiography. However, the scintillation spots in a neutron-sensitive scintillator have not yet been imaged nor measured for size. We developed a high-resolution, real-time neutron induced particle imaging system for observing these particles' trajectories in a scintillator. The developed system is based on a magnifying unit and a cooled electron multiplying charge-coupled device (EM-CCD) camera combined with a lithium-containing silver-doped zinc sulfide (Li-ZnS(Ag)) scintillator plate. Neutrons from a californium-252 (252Cf) source were irradiated to the Li-ZnS(Ag) scintillator and imaged with the system. Using our system, we measured the scintillation spots of the neutron induced particles having different shapes in real time. In some of these measured scintillation spots, those with elliptical shapes were observed due to the trajectories of the particles in the scintillator. The spatial resolution calculated from the widths of the scintillation spots was ∼56 μm. Consequently, the developed imaging system is promising for research on neutron imaging that requires high spatial resolution.

    Objective. Prompt x-ray imaging using a low-energy x-ray camera is a promising method for observing a proton beam's shape from outside the subject. Furthermore, imaging of positrons produced by nuclear reactions with protons is a possible method for observing the beam shape. However, it has not been possible to measure these two types of images with a single imaging system due to the limited imaging capability of existing systems. Imaging of both prompt x-rays and the distribution of positrons may compensate for the shortcomings of each method.Approach. We conducted imaging of the prompt x-ray using a pinhole x-ray camera during irradiation with protons in list mode. Then, after irradiation with protons, imaging of annihilation radiations from the produced positrons was conducted using the same pinhole x-ray camera in list mode. After this imaging, list-mode data were sorted to obtain prompt x-ray images and positron images.Main results. With the proposed procedure, we could measure both prompt x-ray images and induced positron images with a single irradiation by a proton beam. From the prompt x-ray images, ranges and widths of the proton beams could be estimated. The distributions of positrons were slightly wider than those of the prompt x-rays. From the time sequential positron images, we could derive the time activity curves of the produced positrons.Significance. Hybrid imaging of prompt x-rays and induced positrons using a pinhole x-ray camera was achieved. The proposed procedure would be useful for measuring prompt x-ray images during irradiation to estimate the beam structures as well as for measuring the induced positron images after irradiation to estimate the distributions and time activity curves of the induced positrons.

    Abstract High-resolution imaging of alpha particles is required in the detection of alpha radionuclides in cells or small organs for the development of radio-compounds for targeted alpha-particle therapy or other purposes. We developed an ultrahigh resolution, real time alpha-particle imaging system for observing the trajectories of alpha particles in a scintillator. The developed system is based on a magnifying unit and a cooled electron multiplying charge-coupled device (EM-CCD) camera, combined with a 100-µm-thick Ce-doped Gd3Al2Ga3O12 (GAGG) scintillator plate. Alpha particles from an Am-241 source were irradiated to the GAGG scintillator and imaged with the system. Using our system, we measured the trajectories of the alpha particles having different shapes in real time. In some of these measured trajectories, the line shapes of the alpha particles that flew in the GAGG scintillator were clearly observed. The lateral profiles of the alpha-particle trajectories were imaged with widths of ~ 2 µm. We conclude that the developed imaging system is promising for research on targeted alpha-particle therapy or other alpha particle detections that require high spatial resolution.

    Prompt secondary electron bremsstrahlung X-ray (prompt X-ray) imaging using a low-energy X-ray camera is a promising method for observing a beam shape from outside the subject. However, such imaging has so far been conducted only for pencil beams without a multi-leaf collimator (MLC). The use of spread-out Bragg peak (SOBP) with an MLC may increase the scattered prompt gamma photons and decrease the contrast of the images of prompt X-rays. Consequently, we performed prompt X-ray imaging of SOBP beams formed with an MLC. This imaging was carried out in list mode during irradiation of SOBP beams to a water phantom. An X-ray camera with a 1.5-mm diameter as well as 4-mm-diameter pinhole collimators was used for the imaging. List mode data were sorted to obtain the SOBP beam images as well as energy spectra and time count rate curves. Due to the high background counts from the scattered prompt gamma photons penetrating the tungsten shield of the X-ray camera, the SOBP beam shapes were difficult to observe with a 1.5-mm-diameter pinhole collimator. With the 4-mm-diameter pinhole collimators, images of SOBP beam shapes at clinical dose levels could be obtained with the X-ray camera. The use of a 4-mm-diameter pinhole collimator attached to the X-ray camera is effective for prompt X-ray imaging with high sensitivity and low background counts. This approach makes it possible to image SOBP beams with an MLC when the counts are low and the background levels are high.

    Abstract A new experimental method to search for T-violating transverse muon polarization (PT) in the K+ → π0μ+ν decay was recently proposed. In this new experiment, the measurements of the μ+ momentum vector, the π0 momentum vector, and the μ+ polarization will be performed by the same segmented calorimeter. One of key issues is the choice of a scintillation material which can maintain the μ+ spin polarization for several μ+ lifetimes. A test experiment to measure the μ+ spin relaxation time in various scintillating materials was carried out at J-PARC Material and Life Science Facility (MLF). It was concluded that the residual μ+ polarization in CeF3 is high enough to perform the proposed T-violation experiment.

    PURPOSE: Although real-time imaging of the high-activity iridium-192 (Ir-192) source position during high-dose-rate (HDR) brachytherapy using a high-energy gamma camera system is a promising approach, the energy window was not optimized for spatial resolution or scatter fraction. METHODS: By using a list-mode data-acquisition system that can acquire energy information of a cerium-doped yttrium aluminum perovskite (YA1O3: YAP(Ce)) gamma camera, we tried to optimize the energy window's setting to improve the spatial resolution and reduce scatter fraction. RESULTS: The spatial resolution was highest for the central energy of the window at ∼300 keV. The scatter fraction was also smallest for the central energy of the window at ∼300 keV, and the scatter fraction was more than 48 % smaller than that for the full energy window. CONCLUSIONS: We clarified that the spatial resolution can be improved and the scatter fraction can be reduced through optimizing the energy window of the YAP(Ce) gamma camera by setting the central energy of the window to ∼300 keV for HDR brachytherapy.

    Abstract Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are both established imaging technologies in nuclear medicine that are clinically available. However, simultaneous PET and SPECT nuclide imaging is difficult to accomplish with current equipment because of their distinct principles. In light of this, we have developed and demonstrated a GAGG scintillator based Compton-PET hybrid imaging system capable of performing PET and Compton imaging simultaneously. Alternatively, the CeBr3 scintillator possesses more desirable properties, including a high light yield (&gt;60000 photons/MeV), a fast decay time (∼19 ns), and an excellent energy resolution (&lt;4%@662 keV). Herein, we developed an 8 × 8 array of CeBr3 detector based instrumentation by using 64 channel fast signal processing slew rate limited Time over Threshold (ToT) based application-specific integrated circuits and a field programmable gate array ToT data acquisition system with a 62.5 ps accuracy. Furthermore, we evaluated the system’s basic performances. The mean and greatest energy resolutions were 10.1% and 6.0% (FWHM) for 662 keV. The time resolution was 239 ps (FWHM) after offset calibration. We also achieved a proof-of-concept based on single source.

    PURPOSE: Measurement of the dwell time and moving speed of a high-activity iridium-192 (Ir-192) source used for high-dose-rate (HDR) brachytherapy is important for estimating the precise dose delivery to a tumor. For this purpose, we used a cerium-doped yttrium aluminum perovskite (YA1O3 :YAP(Ce)) gamma camera system, combined with a list-mode data acquisition system that can acquire short-time sequential images, and measured the dwell times and moving speeds of the Ir-192 source. METHODS: Gamma photon imaging was conducted using the gamma camera in list mode for the Ir-192 source of HDR brachytherapy with fixed dwell times and positions. The acquired list-mode images were sorted to millisecond-order interval time sequential images to evaluate the dwell time at each position. Time count rate curves were derived to calculate the dwell time at each source position and moving speed of the source. RESULTS: We could measure the millisecond-order time sequential images for the Ir-192 source. The measured times for the preset dwell times of 2 s and 10 s were 1.98 to 2.00 s full width at half maximum (FWHM) and 10.0 s FWHM, respectively. The dwell times at the first dwell position were larger than those at other positions. We also measured the moving speeds of the source after the dwells while moving back to the afterloader and found the speed increased with the distance from the edge of the field of view to the last dwell position. CONCLUSION: We conclude that millisecond-order time sequential imaging of the Ir-192 source is possible by using a gamma camera and is useful for evaluating the dwell times and moving speeds of the Ir-192 source.

    <p>We have developed spatiotemporal measurement and analysis techniques in x-ray photoelectron spectroscopy. To begin with, time-division depth profiles of gate stacked film interfaces have been achieved by NAP-HARPES (Near Ambient Pressure Hard x-ray Angle-Resolved PhotoEmission Spectroscopy) data. We then have promoted our methods to quickly perform peak fittings and depth profiling from time-division ARPES data, which enables us to realize 4D-XPS analysis. It is found that the traditional maximum entropy method (MEM) combined with Jackknife averaging of sparse modeling in NAP-HARPES data is effective to perform dynamic measurement of depth profiles with high precision.</p>

    We have developed novel scintillation crystals based on Ce-doped (Gd,La)2Si2O7 grown by the floating zone and Czochralski methods for oil well logging. The light output of 35,000 photons/MeV or more was kept in the temperature range from 25 to 150 ºC for these crystals. Ce: (Gd, La)2Si2O7 single crystals can be applied to oil well logging and other radiation detection application under high temperature conditions.

    LiF/CaF<inf>2</inf>/LiBaF<inf>3</inf>ternary eutectic scintillators were grown by the µ-PD method. In the solidified eutectic the phases were uniformly distributed in the transverse direction and aligned along the growth direction. For the Eu-doped samples, the expected emission peak observed at 425 nm was ascribed to Eu2+5d–4f transition from Eu:CaF<inf>2</inf>under X-ray excitation. The LiF/CaF<inf>2</inf>/LiBaF<inf>3</inf>ternary eutectic scintillators showed a light yield around 7,000 photons/neutron and decay time of 260 ns (73.6%) and 50 ns (26.4%).

    This article presents the development of the tube shape-controlled oxide scintillator directly grown from a melt via the micro-pulling-down method. We grew tube shape-controlled Ce doped Y3Al5O12 (tube-Ce:YAG) single-crystal scintillators with shape control using the µ-PD method, which we have reported in previous paper. We also developed and evaluated the diced Eu:SrI2 scintillator arrays and their scintillation properties for radiation imaging application. Using a novel dicing technique specific to halide scintillation crystals, a high-energy resolution scintillator array is developed that is cost-effective and widely applicable. Finally, these techniques and development were applied for the novel imaging method we proposed, called scintillation active collimator (SAC). These results demonstrated that the SAC could be promising imaging method for the future medical imaging application.

    東京電力ホールディングス(株)福島第一原子力発電所では、燃料デブリの取り出しが開始されようとしている。燃料デブリは、表面線量率が極めて高く、かつ、組成が不均一のため、取り出し時の仕分けに必要な非破壊測定技術が求められている。本件では、上記に向け、CeBr3シンチレーターを採用した高線量率特化型ガンマ線スペクトルメトリシステムを開発し、それを1 Sv/hを超える高線量率ガンマ線場において特性評価を実施したので報告する。

    Staphylococcus argenteus is a novel species separated from a strain of coagulase-positive, non-pigmented S. aureus. Although S. argenteus has been reported to occur globally, multilocus sequence type (ST) 2250 is mainly found in Northeastern Thailand. Because conventional biochemical testing misidentifies this pathogen as S. aureus, multilocus sequence typing (MLST) or nucA sequencing is recommended to distinguish between S. argenteus and S. auereus. The patient was a previously healthy 12-year-old boy who was admitted because of right inguinal lymphadenitis and cellulitis. Although intravenous cefazolin was administered, his lymphadenitis worsened and formed an abscess on day 6 of hospitalization. Incision and drainage were performed on day 7 of hospitalization. Cefazolin was changed to oral cefaclor, and the patient was successfully treated over a period of 5 weeks. No recurrence was observed throughout 12-months of follow-up. He had a history of right axillary lymph node abscess 2 months before this admission, which was successfully treated with incision, drainage, and antibiotic therapy. He has lived in Japan since birth and never traveled abroad. He had no opportunity to interact with foreigners. His immune function, especially neutrophil function, was tested and we did not find any dysfunction. First, methicillin-sensitive S. aureus was misidentified from the abscess culture. Subsequently, the causative agent was re-identified as S. argenteus ST2250 based on MLST. To our knowledge, this is the first case of S. argenteus ST2250 infection in Japan. This pathogen should be taken into consideration in the diagnosis if the patient has atypical non-pigmented S. aureus.

    SOI (Silicon-On-Insulator) pixel sensor is promising technology for<br /> developing the high position resolution detector by integrating the small<br /> pixels and circuits in the monolithic way. The event driven (trigger mode) SOI<br /> based pixel sensor has also been developed for the application of X-ray<br /> astronomy with the purpose of reducing the noise using anti-coincidence event.<br /> This trigger mode SOI pixel sensor working with in the rate of kilo Hz is also<br /> a promising scatter detector for advanced Compton imaging to track the Compton<br /> recoiled electrons.

    中性子応力測定法は、材料深部の応力ひずみ状態を非破壊で測定できる唯一の方法である。近年の産業利用の増加によりそのニーズは高まり、測定の高効率化が求められている。測定の高効率化には、中性子検出器の大面積化が有効であるが、He-3ガスが枯渇する現在、He-3検出器の大面積化は難しい。そこで、本研究では、He-3検出器の代替検出器として、LiCAF:Ceシンチレータにプラスチックシンチレータを組み合わせたハイブリッド型シンチレータ検出器に着目し、角度分散型の中性子応力測定装置に応用可能な大面積型の高効率・高分解能シンチレータ検出器を開発することを目的とする。最終的には、本検出器を中性子応力測定装置RESA-1に応用することで、世界トップレベルの性能を有する応力測定装置に高度化することを目標とする。

    Measurement of biomagnetic fields such as magnetoencephalograms (MEGs) and magnetocardiograms (MCGs) is one of the important non-invasive imaging modalities to investigate biological functions and to diagnose disease. We have developed an ultrasensitive optically-pumped atomic magnetometer for biomagnetic measurements. In this study, human MCGs were measured with a potassium atomic magnetometer. The sensitivity of the atomic magnetometer was definitively sufficient for recording of the human MCGs. The measured signals were recovered by considering the frequency characteristics of the atomic magnetometer. The activity of the human heart estimated with the MCG maps showed good agreements with those measured with SQUID magnetometers. These results demonstrated reliability and feasibility of biomagnetic measurements with optically-pumped atomic magnetometers.

    (Cex,Gd1-x)9.33(SiO4)6O2 single crystals were grown by the &micro;-PD method. From the structural analysis, the lattice constants increased with increasing Ce concentration. Two nonequivalent crystallographic sites were found for Gd (Ce), 6h and 4f sites. It was revealed that most of Ce locate at Gd(6h) site. XANES analysis revealed while almost all Ce exist as Ce3+ in the crystals, a trace amount of Ce exist as Ce4+. The X-ray excited luminescence spectra of the crystals showed a peak around 400 nm originating from the Ce3+ 5d-4f transition. The corresponding decay time is about 25 ns.

    Pr:LuAG[(Pr_xLu_<1-x>)_3Al_5O_<12>] has an advantage on very fast emission decay time due to 5d-4f transition of Pr^<3+>. Recently we have developed 2-inch-diameter Pr:LuAG single crystal and measured various scintillation properties of grown crystals. In this work, we obtained the following result; the segregation coefficient of Pr is found to be about 0.062 and 2-inch-diameter crystals are obtained with the solidification fraction of about 0.4 from the melt with the initial concentration of 2.5 at % Pr. The light output of Pr:LuAG single crystal is about three times higher than that in BGO at room temperature. The two emission peaks are found at around 310 and 375 nm by UV excitation. The luminescence decay time is as fast as 21ns and its rise time is as short as 400 ps by pulse X-ray excitation. The optical transmittance without AR coating is about 70% at 310 nm. The light output at 373 K is about 50% higher than that at room temperature.

    Single crystals with nominal composition of (Pr_x, Lu_&lt;1-x&gt;)_3(Ga_y, Al_&lt;1-y&gt;)_5O_&lt;12&gt; (Pr:LuGAG) were grown by the micro-pulling-down (μ-PD) method with RF heating system and their luminescent properties were characterized. Compostions of the crystals were analyzed by electron probe micro analysis (EPMA) measurements. Optical characterization such as photoluminescence spectra, radioluminescence spectra, light yield measurements and decay kinetics were studied. Lattice constants and densities of each crystal were determined. Lattice constants and densities were systematically increased with the amount of Ga concentration. Luminescent properties of Pr:LuGAG were characterized by photoluminescence spectra and decays, radioluminescence spectra and light yield measurements. 5d-4f luminescence was observed for 0&amp;le;y&amp;le;0.6 samples. It was found that 5d -4f emission of Pr^&lt;3+&gt; is quenched only slightly up to y&amp;le;0.4 while density is increased systematically in the range of 0&amp;le;y&amp;le;1.0.

    本提案では、“超高解像度、高速、高エネルギー分解能を可能にする共晶体シンチレータを開発し、光検出器と組み合わせることで超高解像度粒子・光子弁別イメージングを実現することを目的としている。本年度は、高発光量、高エネルギー分解能、高速なシンチレータファイバーを有する共晶体の開発を行うべく、以下の2点の検討を実施した。 (ⅰ) 状態図の未知なREI3-AEI2系の擬二元系状態図を作成 (ⅱ) REI3-AEI2系の共晶点組成/共晶点構造の調査 検討の結果、BaI2-REI3系の共晶体は、BaI2-GdI3, BaI2-YI3, BaI2-LuI3系ではREI3がロッド状となる共晶組織に、BaI2-CeI3,ではラメラー組織となることが明らかになった。すなわち、RE = Gd~Luの元素を選択した場合に、BaI2-REI3系の共晶体は、REI3がロッド形状となる共晶組織になると考えられ、光導波型共晶体シンチレータへと応用できる可能性がある。SrI2-REI3系およびCaI2-REI3系の共晶体では、全てのRE (= Ce, Gd, Y, Lu)でラメラー型となることが判明をした。すなわち、SrI2-REI3系およびCaI2-REI3系においては、どのRE (La~Lu)を選択したとしても、ラメラー型の共晶体結晶となることが示唆された。 また、BaI2-LuI3系において、実際にCe添加を行った共晶体シンチレータ育成を行い、特性表を実施したところ、ロッド相であるLuI3相の発光が確認され、光道波型共晶体シンチレータとして応用ができる可能性があることが判明した。検討結果は、シンチレータ特性に優れたハロゲン系シンチレータをロッド相とした光道波型共晶体シンチレータの実現を示唆する物であり、今後の大型化や検出器試作の道を切り開く画期的な成果となる。作製した小型あるいは大型の共晶体と光検出器との組み合わせによる検出器を試作し、α線、β線、中性子線、ガンマ線、X線等の密封線源を用いた粒子、光子の飛跡検出、弁別に関する原理実証までを実施する計画である。

    The purpose of this research project is integrating two completely different modality using magnetic field and gamma-ray emission. The strong magnetic field is used in MRI(Magnetic Resonance Imaging) with atomic nuclear spin, on the other hand, PET(Positron Emission Tomography) uses gamma-rays and positrons emitted from unstable nuclei with high sensitivity molecule detection capability. In this research, focusing on the cascade gamma-rays emitted from unstable nuclei, the magnetic information is extracted via gamma-ray spatio-temporal distribution with high sensitivity and the position information is successfully reconstructed from the measured gamma-ray and magnetic field.

    In the present study, positron annihilation lifetime spectroscopy using ultrashort gamma-ray pulses (GiPALS) has revealed the existence of defect pairs of cationic vacancies and oxygen vacancies, which are responsible for the degradation of Ce:GAGG scintillators. It was found that defect complexwes of antisite defects and oxygen vacancies are introduced as charge compensators for the cationic vacancy charges, causing useless long-lived emission in the scintillator. The codoping method was effective in suppressing the defect complexes. Practically, when magnesium was cooped, the cationic vacancies disappeared. The long-lived luminescence and electron trapping centres were also significantly suppressed by magnesium codoping.

    The effect of group 4-6 ions, such as Mo and W, co-doping on the scintillation properties of various scintillator crystals grown by the micro-pulling down (μ-PD) method was investigated for the first time. The optimal co-doping ion concentrations for the best scintillation properties were found. Crystals with optimized compositions were grown also as 1-inch boules by the Czochralski (CZ) technique. Chemical composition, optical properties, luminescence characteristics, and scintillation characteristics for the grown crystals were investigated. Such data gave the information for the fine composition and growth parameters adjustment. Additionally, the luminescence mechanism of the grown crystals was investigated and discussed together with Professor Nikl, an international collaborator. The deep understanding of such a mechanism enabled further improvement of the scintillation properties of co-doped crystals.

    Conventional gamma-ray imaging methods suffer from fundamental limitation arising from their principles. For example, the spatial resolution of PET and the detection efficiency of SPECT are restricted by the positron range and the collimator, respectively. Our new imaging method based on temporal and spatial correlation among multiple gamma rays can identify gamma-ray emission point from only one event. The spatial resolution of the method is not affected by a positron range. In this research, we have found such nuclides that emit multiple gamma rays in series. We have started from the establishment of each technique and finally fabricated an imaging system for multiple gamma ray coincident imaging. Then we have applied the system to visualize phantom, mouse scan, and proven the reconstruction-free gamma-ray imaging. We have obtained the peptide accumulation image of the tumor region with radioisotopes.

    We have developed a calcium iodide (CaI2 ) scintillator and aim to launch the sensitive dark matter search and double beta decay search experiment using it in the future. In order to increase the sensitivity of experiments, three pillars are generally important: low threshold and high resolution, large size, and low background (BG). We have succeeded in producing CaI2 crystals with a luminous intensity 2.7 times higher than that of NaI(Tl), demonstrating that low threshold and high resolution can be achieved. As for the larger size crystal, a dedicated CaI2 furnace was set up, and 2-inch size crystals were developed. We also conducted basic research on low BG technology using waveform discrimination method, and demonstrated very high particle discrimination ability of CaI2.

    Chemical vapor deposition of highly ordered nanostructures under an intense laser field improves freedom in design and material selection with following advantages: utilizing self-organized nanostructures as ceramic coatings, reducing processing temperature of single-crystalline materials by half in comparison to melt-solidification process, and designing coatings including non-thermodynamically stable phases and compositions. In this research project, alumina- and ferrite-based nanocomposite coatings have been synthesized and characterized in terms of mechanical, optical, and magnetic properties. Hafnia coatings exhibited a self-orientation growth, and CVD route to transparent thick films of Eu-doped hafnia and lutetia for phosphors has been developed. Ceramic coatings with highliy ordered nanostructures have been synthesized in alumina-hafnia, -lutetia, and -yttira systems. Epitaxially grown strontium hexaferrite and yttrium iron garnet showed excellent magnetic properties.

    In this research, we have optimized the crystal composition, surface treatment, and annealing condition for maximizing scintillator properties of fast-type GAGG single crystal with co-doping. As a result, we found a composition with a scintillation decay time of 36 ns and a timing resolution of 160 ps while keeping the light yield. Furthermore, we advanced development of large-scale crystal growth technology for fast-type GAGG. In addition to the adjustment of the temperature gradient by the examination of the heat insulating material arrangement condition, the coil position, the growth atmosphere, and the rotation speed were optimized, and the crystal of 3 inches in diameter x 150 mm in length was stably produced. With the cooperation of Furukawa Scintitech Co., Ltd., the fast-type GAGG was mounted on a PET device, and a resolution of 0.98 mm FWHM and a sensitivity of 1.31% were achieved.

    BNA fiber single crystals were grown by the m-PD method. Crucible materials and shape were designed according to wetness between BNA and the crucible materials. Finally BNA fiber single crystal with about 1-2 mm diameter was successfully grown by using the polystyrene crucible. The grown BNA crystal showed single Orthorhombic phase. The grown BNA crystal showed 19.7 arcsec of line width of rocking curve. This value is superior to that of the reported BNA crystals grown by the solution growth (~30 arcsec) and Bridgeman method (~100 arcsec). THz-wave generation from 4 THz up to 14 THz from the m-PD grown BNA fiber was demonstrated. Positivity of high crystallinity BNA single crystal growth by the m-PD method was evidenced by this study.

    中性子イメージングへの応用をめざし、中性子線球種断面積の高い6Liを含有する三元系共晶体として、ファイバー状構造をとるLiF/CaF2/LiBaF3共晶体をマイクロ引き下げ法により育成した。光導波構造を有し、シンチレータをファイバー構造となる透明な三元系共晶体の作製に世界で初めて成功した。当該共晶体は、CaFシンチレータ相におけるEu2+ 4f-5d遷移由来の発光を420nmに確認した。また、252Cf線源による熱中性子を照射し、260 ns (73.6%) ,50 ns (26.4%)の蛍光寿命と7000 ph/nの発光量を確認した。LiF/CaF2/LiBaF3 共晶体はLiの含有量が67.9%と高いため、高感度な中性子検出が可能となる。ファイバー構造を活かした中性子線イメージング装置への応用が期待できる。

    μ-PD法を用いたファイバー単結晶作製技術を応用し、融液成長法によるBNA単結晶ファイバー作製の検討を行った。始めに、材料と坩堝材の濡れ性とBNAとの反応性の観点から検討し、ファイバー状への制御がもっとも容易な坩堝材および形状を設計した。その結果、成長速度0.1mm/minにて、[010]面を選択制御した約0.8mm径のファイバー状結晶の作製に成功した。得られた結晶についてX線ロッキングカーブを測定し、[010]面において20arcsec以下の結晶性を確認した。さらに、KTP結晶を用いた二波長光パラメトリック発振器(OPO)からの800-1000 nmの近赤外励起光を用いたTHz波発生システムを用いて、当該BNAファイバー単結晶からのTHz波の発生を確認した。
