Abstract

In order to determine the theoretical performance of a multi-layer scintillator crystal used in small PET scanners, we have used the DETECT2000 Monte-Carlo simulation of the light transport in scintillation crystal software. The results given by this software demonstrate that some of the individual crystals in the block could not be distinguished. Also we have found out that the layer connecting the different crystals degrades the performance of the scintillation block. Simulation of thinner interconnecting layers suggest that much better crystal identification could be obtained
