Abstract

Method and system for determining the spatial response signature of a x-ray detector comprising a photostimulable phosphor by generating a flat field image of the detector, generating a low-pass filtered version of the flat field image and background demodulating the flat field image by pixel-wise dividing it by means of corresponding pixel values in the low-pass filtered version.
