ABSTRACT:
An improved method and apparatus for energy window selection in a radiation signal processing system which in a preferred embodiment includes obtaining energy level histograms corresponding to corrected spatial elements and determining a standard count of radiation events to be accepted by each true spatial element in response to a flood image. The energy window of each corrected spatial element is then adapted to cause each to accept the standard count of radiation events in response to a flood image whereby greater uniformity of image may be accomplished in the imaging process.
