摘要: Abstract The multi-pixel photon counter (MPPC) or silicon photomultiplier (SiPM), recently introduced as a solid-state photodetector, consists of an array Geiger-mode photodiodes (microcells). It is promising device for PET due to its potential high detection efficiency (PDE) and foreseeable immunity magnetic fields. also easy use with simple read-outs, has gain small size. In this work we evaluate the in field performance three 1×1 mm2 (with 100, 400 1600 microcells, respectively) one 6×6 mm2 (arranged 2×2 array) Hamamatsu MPPCs their imaging. We examine dependence energy resolution these devices on temperature reverse bias voltage, when coupled LYSO scintillator crystals under conditions that would find system. microcells models are suitable small-size crystals, like those employed animal scanners. have confirmed good up fields 7 T well suitability performing acquisitions presence fast switching gradients duty radiofrequency MRI sequences.
