Abstract
A gamma ray imaging detector for nuclear medical imaging includes an array of photodiode detectors provided on opposite surfaces of a scintillating crystal. By measuring the relative distribution of detection signal intensities produced by each photodiode in each array, it becomes possible to measure the depth of interaction of a gamma ray absorption event along the Z axis direction of the crystal in addition to its spatial position in the X-Y plane of the crystal and its absorption energy. The value of the measured depth of interaction is subsequently used in refining the calculation of the spatial location and improving the performance characteristics of the imaging detector.
