Abstract
A system calibrates a solid state detector () for a radiation imaging device () in a single acquisition. A calibration phantom () emits radiation concurrently at at least first and second characteristic energy levels. A nuclear camera () generates associated sets of radiation data spanning both the first and second energy levels from the emitted radiation that is received by solid state detector (). A means () determines associated centers of energy peaks and energy values of the generated data sets. A calibration means () calibrates at least one of gain, offset, performance and dead pixel correction based on the determined centers and peaks of the acquired data sets.
