1. A nuclear camera system comprising: a detector for receiving radiation from a subject in an exam region, the detector including: a scintillation crystal that converts radiation events into flashes of light; an array of sensors arranged to receive the light flashes from the scintillation crystal, a plurality of the sensors generating a respective sensor output value in response to each received light flash; and a processor for determining when each of the radiation events is detected, at least one of an initial position and an energy of each of the detected radiation events being determined in accordance with respective distances from a position of the detected event to the sensors, and generating an image representation from the initial positions and the energies.
