10. A system for limiting coincidence data, comprising:
a memory encoding processor-executable routines;
a processor configured to access the memory and to execute the processor-executable routines, wherein the processor-executable routines, when executed by the processor, cause the processor to:
detect a plurality of coincidence events during a scan of a subject with a detector array of a positron emission tomography (PET) scanner, wherein the PET scanner comprises a plurality of detector rings disposed along a longitudinal axis of the PET scanner, and each detector ring comprises a plurality of detectors; and
limit data associated with the plurality of coincidence events from the scan so that the data varies in a radial extent relative to a center of a field of view of the scan.
