System for imaging the distribution of photon emitting material from a distributed radiation source including a scintillator, photodetectors viewing the scintillator, signal processor, data processing, storage and display. Method of locating a plurality of radiation sources and providing an improved image of their distribution by comparison of radiation responses from known locations with radiation responses from unknown locations. Calibration method for recording characteristic response data from known locations using uniformly irradiating source. Sorting and ordering process of data processing simplification. Structures enhancing position signals at the expense of response uniformity.
