Abstract :
This report characterizes a new set of SiPM (Silicon Photomultiplier) Detector Blocks for use in PET systems. This novel block consists of 9 arrays of 16-pixel SiPM detectors. Each pixel is 3mm by 3mm and the whole detector block is 46mm by 46mm by 133mm. the detector data is modified within each detector block and digital output comes out of each block. The digital output is then further processed in the coincidence board. The coincidence board is capable of supporting up to 16 individual detector blocks and connects to the computer via a fast USB cable.
