Multiple pixel area-weighted acquisition system for scintillation cameras

摘要

Upon the detection of a scintillation event at an event pixel, a plurality of associated pixels are identified (46). Weights are assigned (50) to the event pixel and to all of the associated pixels in such a manner as to attribute the event over an area in a statistically accurate manner. A current sum of all weights which have been previously assigned to each pixel is stored (52). Unblank signals are generated (54), based upon this current sum, and the current sum is updated (48) to account for the number of unblank signals so generated.
