Abstract: A method for reshaping the characteristic exposure response and dosimetry of a direct radiography system into a specified exposure response profile by pixel-wise converting image data according to a response transfer model which is derived from an x-ray generator' s post exposure parameters data associated with image signals obtained at various exposure levels during system calibration and from a few extra dose measurements and their corresponding post exposure data also gathered during system calibration under reference exposure conditions.
