At present, the resolution of positron emission tomography (PET) is sub-millimeter. Pixel size and parallax error are considered as two of the factors that limit spatial resolution. We plan to apply 500-μm-pitch silicon photomultiplier (SiPM) arrays, which have a recovery time of 8 ns and a gain of 1 × 10⁶, in dual-sided readout to improve the performance of PET system.
