摘要

RECENTLY, there has been great interest in the study of deriving PET event information from digitally sampled event waveforms. We have reported the feasibility of Multi-Voltage Threshold (MVT) based PET DAQ system using field — programmable-gate-array (FPGA) without ADC and TDC. The goal of this study was to extend MVT based multi-channel analog circuit and DAQ with FPGA which could be utilized for the development of a functional PET system.
