Abstract
The invention concerns an evaluation apparatus () for evaluating gamma radiation events detected by a gamma camera () and identifying valid gamma radiation events, said (gamma camera () including a scintillator () for emitting scintillation photons () at photo conversion positions () in the scintillator () in response to incident gamma rays () and resulting gamma radiation events and a position-sensitive photodetector() for detecting emitted scintillation photons () and obtaining therefrom a spatial signal distribution (). The invention further concerns a calibration apparatus () for in-situ calibrating a position-sensitive photodetector () of a gamma camera () for the detection of gamma radiation events.
