Abstract
Light emitting diodes (LEDs) at fixed locations are placed at the entrance face of the scintillator within the detector head of a scintillation camera system. By energizing the LEDs, surrogate scintillation events may be generated and processed by the scintillation camera system. Information thus acquired can be used to maintain the photodetectors in a well-tuned state, to identify baseline shifts in the preamplifier channels and to determine system deadtime.
