Abstract

In order to study light transport in LSO crystals for PET, we simulated single crystals and block detectors using Detect2000. We devised basic experiments to evaluate fundamental physics parameters of the simulation and benchmarked the simulation with a set of experiments on single crystals. The block detectors that were studied were composed of Lutetium Oxyortho-Silicate crystals, a light guide and Photo Multiplier Tubes. The results of the simulation were compared to an experimental detector block´s position profile. By refining our simulation to model actual detectors, a tool was created that can be used to optimize the performance of detector blocks.
