Abstract

The performance of a YSO/LSO detector blocks design with high resolution and high count rate capabilities were studied in the Positron emission tomography (PET) and single photon emission computerized tomography (SPECT) systems. YSO and LSO were combined in a phoswich detector block, where the YSO was placed in a front layer and was used for low energy SPECT imaging. LSO in the second layer was used for PET imaging. Events in the two detector materials can be separated by pulse shape discrimination, since the decay times of the light in YSO and LSO are different. There was no difference in resolution seen in the reconstructed images between the collimator and scintillator camera systems, and the block detector camera systems.
