ABSTRACT:
The scintillation camera includes a plurality of individually pulsible light emitting devices associated with a number of the photomultiplier tubes. By pulsing the light emitting device, certain ones of the photomultiplier tubes of the camera receive substantial amounts of light. Values from the certain photomultiplier tubes are compared to one another for carrying out an effective gain adjustment of at least one of the certain tubes. The gain calibration is independent of the amount of light emitted from the light emitting devices. There is also provided a method of adjusting the effective gain of the camera by using the readings resulting from a gamma ray induced scintillation instead of the pulsible light emitting devices.
