Abstract
Pulse pile-up limits the ability of a .gamma. camera to produce high quality images at high count rates. Pulse pile-up results in loss of events and spatial distortions in the image. The test procedures for measuring count rate performance in .gamma. cameras were compared. In 4 .gamma. cameras measurements of spectral fraction, count-rate curve, pulse-pair resolution, deadtime, maximum count rate, full width at half maximum of the line spread function and misplaced event count rate were compared. No technique provided a complete description of the count-rate effects in .gamma. cameras. The misplaced-event measurements provided the most information.This publication has 5 references indexed in Scilit:
