摘　　要：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。With the establishment of heavy ion cooling storage ring (CSR) in Institute of Modern Physics, Chinese Academy of Sciences, the DPET (double-sector positron emission tomography) detector is developed. The structure of DPET detector, the principle of detection and characteristic of design are particularly discussed, including the structure of detection crystals, the optical fibers, the design of the signal readout circuit and the electronics data acquisition system. Some results of detector unit performance test are also presented.
