Abstract
A gamma camera has a scintillation medium responsive to radiation stimuli for producing an exponentially decaying scintillation at a location where a radiation stimulus interacts with the medium; a photodetector system responsive to a scintillation for producing outputs; and computation circuitry responsive to such outputs for producing intrinsic signals which have the same temporal nature as a scintillation and which are processed to produce coordinate signals representative of the coordinates of the scintillation producing such outputs. The computation circuitry includes truncation circuitry for electronically shortening the duration of intrinsic signals so that the computation circuitry effectively operates with signals of shorter duration than the scintillations.
