抜粋

We developed a high-precision color gamma-ray image sensor with fine spatial resolution that is cost-effective, widely applicable, and very sensitive by using a diced cerium-doped Gd₃Al₂ Ga₃O₁₂ (Ce:GAGG) scintillator array coupled with a 3.0 × 3.0 mm²/pixel 8 × 8 MPPC-array. The proposed image sensor can measure the energy of individual X-ray photons transmitted through an object. The pixel size of the Ce:GAGG scintillator array is 0.2 mm, and the pixels are separated by 50-μm-wide micro-grooves. The image sensor has a size of 20 × 20 mm² and thickness of 1.0 mm, and it achieved an excellent spatial resolution of 0.3-0.4 mm and energy resolutions of 12% and 18% (FWHM) for 122 and 59.5 keV gamma-rays, respectively. We conducted an experiment to determine the local effective atomic number of metals by using dual-energy gamma-ray sources. In addition, we developed a color-composite image using mixed images taken at three energies (31, 59.5, and 88 keV).
