Method and apparatus to facilitate forming detector-level calibration information for a high energy-based scanner

Abstract

The provision of calibration information for a given high energy-based scanner having a plurality of detectors can comprise forming (103) detector-level calibration information for that scanner. This can comprise calculating (201) a theoretical trajectory as pertains to relative movement as between the plurality of detectors and a calibration object as a function of known geometry parameters for this particular scanner and then causing (202) relative movement as between this plurality of detectors and a calibration object to develop a corresponding observed trajectory for the calibration object. These teachings then provide for determining (203), for each of at least some of the plurality of detectors, a value that corresponds to a difference between the theoretical trajectory and the observed trajectory to thereby provide the detector-level calibration information.
