Abstract
A gamma camera having separate detectors respectively to determine the spatial location and energy of gamma radiation emanating from a patient is disclosed. The preferred camera has two adjacent, mutually perpendicular arrays of parallel, coordinant signal producing scintillaters positioned on the face of a scintillating energy crystal. Each of the fibers within the arrays conducts light resulting from Compton events to an associated one of a set of photodetectors to produce coordinant signals. Other photodetectors monitor the total scintillated energy within the energy crystal. The energy crystal is of sufficient size to absorb energy remaining in each patient emitted gamma ray that has produced Compton events in the coordinant scintillators. The sum of the energies of substantially coincident signals from the fibers and the crystal is used to identify photo peak events.
