Abstract :
A marked-point process model of a position-sensitive detector is developed which includes the effects of detector efficiency, spatial response, energy response, and source statistics. The average mutual information between the incident distribution of gamma -rays and the detector response is derived and used as a performance index of detector optimization. A brief example is presented which uses this figure-of-merit for optimization of light-guide dimensions for the SPRINT IT modular scintillation camera.<>
