The aim of the study was to determine the best parameters for rapid performance of daily quality control testing of intrinsic uniformity for the single-head gamma- camera, by changing one parameter while keeping all other parameter constant. A set of parameters for rapid performance of daily gamma-camera intrinsic uniformity was determined. The intrinsic uniformity improved as the number of counts increased, source strength increased, distance decreased and degrades as volume increased. The best optimized set of values were found to be the collection of 50 millions counts from a source of 50µCi per 50l placed at a distance of 4.5 feet from the camera head. With our recommended parameters, the intrinsic uniformity quality control testing can be performed in 30-40 min with quite good results.
