正电子放射层析系统 (PET)是科学研究的强有力的工具。本文阐述了由两层LSO晶体阵列和最新开发的位置灵敏型光电倍增管构成的新型位敏型探测器的一些特性。结果表明该探测器能够用于小动物PET中。文中最后简述了利用该探测器构筑的微型PET扫描器的初始设计。
Positron emission tomography (PET) is a powerful tool for scientific research. This article describes some of the features of a new type of position-sensitive detector that consists of a two-layer LSO crystal array and a newly developed position-sensitive photomultiplier tube. The results show that the detector can be used in small animal PET. At the end of this article, the initial design of miniature PET scanner constructed by this detector is briefly described.
