Discrete crystal scintillator arrays are widely used in preclinical PET. The crystal size determines the spatial resolution of PET systems. We simulated and evaluated two preclinical PET systems consisting of a monolithic ring based on previous study(MSR) in GATE with different readout methods: Dual-ended readout and Inner-surface readout. The Center-of-Gravity method and neural network algorithm were used to decode interaction positions of single photons and performances of both PET systems were evaluated.
