Abstract
A nuclear camera system includes a detector ( ) for receiving radiation from a subject ( ) in an exam region ( ). The detector ( ) includes a scintillation crystal ( ) that converts radiation events into flashes of light. An array of sensors ( ) is arranged to receive the light flashes from the scintillation crystal ( ). Each of the photomultiplier sensors ( ) generates a respective sensor output value in response to each received light flash. A processor ( ) determines 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 is determined in accordance with respective distances (d . . . d ) from a position of the detected event to the sensors ( ). An image representation is generated from the initial positions and energies.
