Abstract
A radiation detector for a radiation imaging system, wherein the detector comprises photosensors, arranged to receive light emitted from an array of scintillator elements. The scintillator elements absorb radiation, such as gamma rays, and emit light. Using Anger arithmetic and crystal decoding, the position of each scintillation event is determined from the relative fractions of light detected by each of the photosensors. Selectively shaping the top surface, i.e., the surface closest to the photosensors, of each scintillator element in the array, the direction of light emission from each scintillator element can be optimized such that the fraction of light detected by each photosensor is optimally distinct for each position in the array of scintillator elements. The top surface of at least one of the scintillator element array is not parallel with the bottom surface of at least one of the scintillator.
