Calibration method and apparatus for pixilated solid state detector

摘要

A system calibrates a solid state detector ( 20 ) for a radiation imaging device (10) in a single acquisition. A calibration phantom ( 40 ) emits radiation concurrently at at least first and second characteristic energy levels. A nuclear camera ( 16 ) 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 ( 20 ). A means ( 64 ) determines associated centers of energy peaks and energy values of the generated data sets. A calibration means ( 80 ) calibrates at least one of gain, offset, performance and dead pixel correction based on the determined centers and peaks of the acquired data sets.
