Design and Performance of Continuous Sampling Module for Positron Emission Mammography

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。

Abstract: 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.
