The light yield, spatial resolution, and image quality of inorganic scintillators (CsI:Tl (CsI), Gd₃Al₂Ga₃O₁₂: Ce (GAGG), Lu₃Al₅O₁₂: Ce (LuAG), CdWO₄ (CWO), Y₃Al₅O₁₂: Ce (YAG), Bi₄Ge₃O₁₂ (BGO), and Gd₂O₂S: Tb (GOS)) were investigated using monochromated synchrotron radiation. For quantitative analysis, the same imaging system composed of a relay lens system and a camera was used for all scintillators. The light yield of GOS was highest, followed in order by CsI, GAGG, CWO, YAG, LuAG, and BGO. The spatial resolution of micro X-ray radiographic images using GAGG and LuAG was highest, followed by using CsI, CWO, and YAG. The image qualities were almost the same, except for GOS. These results indicate that CsI is suitable for micro X-ray radiography and computed tomography with a low X-ray flux source, and GAGG and LuAG are suitable with a high X-ray flux source.

使用10、20和34keV单色同步加速器辐射对CsI，GAGG，LuAG，CWO，YAG，BGO和GOS闪烁体的物理性质进行定量分析

无机闪烁体（CsI：Tl（CsI），Gd ₃ Al ₂ Ga ₃ O ₁₂：Ce（GAGG），Lu ₃ Al ₅ O ₁₂：Ce（LuAG），CdWO ₄（ CWO），Y ₃ Al ₅ O ₁₂：Ce（YAG），Bi ₄ Ge ₃ O ₁₂（BGO）和Gd ₂ O ₂S：Tb（GOS））使用单色同步加速器辐射进行了研究。为了进行定量分析，所有闪烁体均使用由中继透镜系统和照相机组成的同一成像系统。GOS的光产量最高，其次是CsI，GAGG，CWO，YAG，LuAG和BGO。使用GAGG和LuAG的X射线摄影图像的空间分辨率最高，其次是CsI，CWO和YAG。除了GOS，图像质量几乎相同。这些结果表明，CsI适用于具有低X射线通量源的微型X射线射线照相和计算机断层摄影，而GAGG和LuAG适用于具有高X射线通量源的计算机。
