Effect of Crystal surface treatment on the timing response of a DOI detector for PET

晶体的不同的表面处理影响着总的光输出量 ,进而影响有它们构成的 PET探测器的性能。为了优化设计一个新提出的深度检出型探测器 ,比较研究了不同表面情况的

Different surface treatment on the crystals influents the total light output, and consequently affects the performance of the detectors for positron emission tomography (PET). In order to optimize the performance of a new depth of interaction (DOI) detector, we have focused on the comparison of light output and timing resolution of the detectors consisting of narrow LSO crystals with different surface conditions. The results of this study can provide useful information to implement LSO detectors to practical PET systems.
