ABSTRACT OF THE DISCLOSURE A scintillation camera is provided with multiple linearity correction maps which are accessed as a function of the value of the energy of a detected radiation event, so as to separately correct for spatial dislocation errors in multiple energy ranges as a function of detected position. The correction maps may be obtained by direct measurement of nonlinearities for each of the desired energy ranges individually, or sets of corrections for some energy ranges may be obtained by extrapolation calculation from correction factors which have been obtained by direct measurement.
