ABSTRACT:
A scintillation camera apparatus comprises a plurality of photomultipliers, a plurality of high voltage control circuits, and a comparator. The photomultipliers generate radiation energy signals upon receipt of incidence light. The comparator compares the peak pulse heights of the radiation energy signals with the corresponding reference peak values to derive deviation signals. Based upon the deviation signals, the supply of the high voltages to the photomultipliers is independently controlled.
