Abstract
We investigate the application of LSO and YSO scintillating crystals for Po sitron Emission Tomography (PET). Properties such as light output, energy r esolution, detection efficiency for various energy threshold, and timing re solution are presented. These data allow us to evaluate the usage of finger -like LSO:Ce and YSO:Ce crystals coupled to photomultiplier tube, and to es tablish optimal operating conditions for high-resolution PET. Both crystals have advantages over EGO currently used in PET and LSO is considered as a possible replacement for EGO based systems.
