ABSTRACT:
Digital intensity values from a planar array of photodetectors optically coupled to a scintillator in a digital electronic scintillation camera are compared to one another from most significant bit down to least significant bit in order to determine within the limits of precision of the digital values which photodetector has the maximum light intensity. Center photodetector determination is an important part of efficient position calculation in a scintillation camera.
