Abstract
This paper describes a computer program that is used to analyze the field uniformity of gamma cameras. The daily floods collected on the gamma camera are digitized and analyzed. The program calculates a number of quantities that pertain to the flood image as a whole and also the counts and the standard deviation in small areas centered over each photomultiplier tube. These daily results are compared either to a standard reference image or to the results averaged over the previous five days. Changes in the region of each photo-multiplier tube are displayed as an artificially constructed image. Observers find it easier to detect changes in this artificially constructed image than in the original image.
