ABSTRACT:
A PET scanner operates in a calibration mode to produce timing calibration sinograms. These sinograms are employed to calculate time delay adjustment values for each detector channel. These values are downloaded to data acquisition circuits in each detector channel to adjust the delay of event data pulses that indicate the occurrence of a coincidence event. The process is repeated until the downloaded time delay values are reduced below preset criteria.
