ABSTRACT:
Correction of scintillation event data from a nuclear medicine imaging system for effects of pulse pile-up is carried out by separating event data packets into total energy and individual detector energy data packets, executing pile-up correction algorithms on each of the separated packets simultaneously using a pipeline processing architecture, and reassembling the corrected data packets into corrected scintillation event data packets. Pulse tail correction information for each individual detector is stored in a storage medium for a present event and immediately preceding event for which correction information exists, which allows individual detector correction information to be retrieved by using a look-up procedure, thereby enabling correction to be performed within a single processor cycle.
