依托中国科学院近代物理研究所的HIRFLCSR重离子冷却储存环,研制了肿瘤组织诊断用对扇形正电子断层影像(DPET,doublesectorpositronemissiontomography)探测器。介绍了肿瘤组织诊断用DPET探测器的晶体构形、传输光导选择、信号读出电路设计和电子学获取系统,给出了探测器探测单元的一些测试结果和结果讨论。
Relying on the HIRFLCSR heavy ion cryogenic storage rings of the Institute of Modern Physics, Chinese Academy of Sciences, a double-detector positron emission tomography (DPET) detector for tumor diagnosis was developed. This paper introduces the crystal configuration of DPET detector for tumor diagnosis, the selection of transmission light guide, the design of signal readout circuit and the electronic acquisition system. Some test results and discussion of the results are given.
