Data Acquisition Electronics for PET Mammography Imaging
The purpose of this paper is to present recent developments in the off-detector electronics of a PET (Positron Emission Tomography) system for mammography imaging. In particular, problems and solutions associated with the integration of its Data Acquisition Electronics are targeted. Synchronism is a critical issue in the DAE system. A resynchronization module is proposed to solve communication problems with the internal asynchronous busses with limited degradation of the communication rate, as compared with fully synchronous solutions. Data processing refers to 64 dual-channels, 11bit/channel, at a frequency of 100MHz. The maximum of the DAE output rate is 220 MB/s corresponding to 1 MCoincidence/s. The robustness of the proposed solutions has been validated with software simulation and hardware implementation. Results of test and validation on FPGA, boards and buses are presented.
