Abstract
The afterglow and count rate/dead time of a nuclear imaging detector are calculated for use in correcting event detection and energy integration circuits. Energy value signals and event triggering signals are respectively integrated as a function of the decay setting of the detector, until they reach stable values, which are respectively used as afterglow and count rate/dead time signals used by a data processor of the detector.
