Abstract

Silicon photomultiplier technology based on Geigermode avalanche in p-n junction has made unforeseen progress for the last 5-6 years. With its high gain and high photon detection efficiency, it has shown that it could replace PMTs in many applications including time-of-flight PET. Also, its magnetic immunity and compactness made it very suitable for PET-MR detector. In this paper, we present time-of-flight PET-MR detector based on silicon photomultiplier from its selection, prototype test with discrete electronics, ASIC and a module design. Also, the system performance data is presented.
