乳腺专用PET连续采样电子学系统设计与性能测试

Design and Performance of Continuous Sampling Module for Positron Emission Mammography

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.Sub-module 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.
