Design and Performance of Continuous Sampling Module for Positron Emission Mammography

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.
