Digital Photon Counters (DPCs) are a new technology capable of detecting light similar to a Silicon Photomultiplier. In previous work we characterized the Philips DPC-3200-22_C DPC array for use in small-animal PET. Among other performance aspects studied was a reduction in detector efficiency from Neighbor Logic (NL) malfunction. NL forces neighboring DPC elements into a readout cycle after the first...
Arrays of silicon photo-multipliers (SiPMs) are good candidates for the readout of detectors in PET MR inserts due to their high packing density, efficiency, low bias voltage and insensitivity to magnetic fields. In this study we report the readout performance of SensL SiPM arrays in terms of their ability to resolve all elements of pixellated lutetium oxy-orthosilicate (LYSO) crystals, and their...
