Multi-Voltage Threshold Based Front-End Circuit and DAQ with FPGA for PET

초록

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. © 2015 IEEE.
