A method for use with a scintillation camera which detects radiation events having energies within two different energy ranges and distorts spatial coordinates of detected events in the two ranges differently, a spatial coordinate set is determined for each event, each coordinate set is adjusted using a first set of predetermined correction factors calculated to eliminate distortion in events within a first of the energy ranges yielding first corrected coordinate sets corresponding to events within the first energy range and adjusted sets corresponding to events within the second energy range, adjusted sets are further adjusted using a second set of predetermined correction factors calculated to eliminate distortion in the adjusted sets yielding corrected second sets, the first and second sets are then used to generate first and second images, respectively.
