Abstract:
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 that analyzes the sensor output values for detecting a start of the event, determines (a) an initial position and an energy of each of the detected radiation events (b) respective distances from the initial position of the detected event to the sensors, and (c) a corrected position and energy of each detected radiation event in accordance with weighing values which are generated based on the respective distances from the determined initial position of each detected event to the sensors, and generates an image representation from the corrected positions and the energies.
