Time response of a Silicon Photomultiplier (SiPM) depends on some of the intrinsic parameters of the sensor. Combining multiple small SiPM instead of one with larger area will reduce detector capacitance at electronic level, which can be translated into a lower jitter, and thus better Coincidence Time Resolution (CTR) of a PET system. This work provides a framework by combining GATE and an...
