Abstract
Performance of the MGH positron camera, PCR-I, is evaluated at high count rates. System resolution is maintained throughout the operating range of the instrument. The analysis of dead-time losses and random coincidence events is complicated by the analog coding system implemented in PCR-I. However, the system non-idealities can be analyzed, and corrections applied to compensate for them. An experiment demonstrating the efficacy of the count rate corrections is presented.
