Abstract
The intensity distribution of a radiation field imaged on a scintillation crystal of a gamma camera can be quantified by assigning to each elemental area of the crystal, a number representing the number of light events calculated to have occurred in the given elemental area within a predetermined period of time. The resolution of the camera is improved by weighting the contents of the elements in the memory in accordance with the probability that an event, calculated to have occurred in a given elemental area, actually occurred therein, such that the weighted contents of the memory more closely approaches the actual density distribution of light events as compared to the unweighted contents of the memory.
