8×16-pixel array (16×16-pixel also available) CMOS Silicon Photomultipliers (SiPM) for PET applications. Each pixel is 570x610um2 and consists of 720 SPADs, two 12-b 64-ps TDCs and two 7-b photon counters. Total counts are externally provided at 100M samples/s while internal discriminator logic allows an efficient cancellation of non-gamma events.
