乳腺专用PET连续采样电子学系统设计与性能测试

摘要

对乳腺专用PET进行了简单介绍,详细叙述了系统中连续采样电子学系统的设计和性能测试.该电子学采用子母板设计结构,包含了模数转换、时间数字转换和CAN控制等多个模块,具备对前端探测器模拟信号进行连续采样、处理和传输功能.实验表明,该系统能完全满足乳腺专用PET对连续采样的需求.该系统还有集成度高、通用性强、配置灵活等优点.%Design and performance of data processing electronics (continuous sampling module, CSM) for positron emission mammography (PEM) was introduced. Submodule of ADC and TDC was allocated on daughter board and mother board of CSM,respectively. There was also a CAN controller on mother board. Continuous sampling of front-end analog signals, data processing and transmission were implemented in the design. Evaluation and performance show that the CSM is fulfilled the requirement of high-rate data processing in our PEM. The high-integrated CSM can be configured flexibly and can be extended to other system easily.
