Abstract
We have proposed a novel edge-readout detector design for PET, which can easily provide sub-millimeter in-plane spatial resolution together with DOI information with resolution determined by the thickness of the crystal layers. Multiple factors that can potentially affect the coincidence resolving time (CRT) have been studied in this work. The result indicates there is a strong correlation between the coincidence resolving time and the parameters of a constant fraction discriminator (CFD), while the correlation between CRT and other factors such as inclusion of optical barriers, locations of gamma-ray interactions in the detector and light-coupling material's refractive index (between crystal and SiPM's silicon substrate) is weak. With optimum CFD parameters, a 200-ps CTR can be achieved.
