摘　　要：依托中国科学院近代物理研究所的重离子冷却储存环HIRFL-CSR,研制出了肿瘤组织诊断用对扇形正电子断层影像)装置。将简要介绍为其研发的后继电子学处理系统。该系统主要由放大,甄别,多路符合,输出延时可调,输出脉宽调节等电路构成。该系统具有定时精确、结构紧凑、体积小等特点。With the establishment of heavy ion cooling storage ring （CSR） in Institute of Modern Phys- ics, Chinese Academy of Sciences, the DPET （double-sector positron emission tomography） equipment has been developed. The electronics data acquisition system designed for the DPET is particularly discussed in this paper. The system consists of amplification unit, discrimination unit, coincidence unit, pulse width adjusting unit and delay adjusting unit et al.
