ABSTRACT:
Scattered radiation in an X-ray image causes a reduction of contrast. An estimate of the scattered radiation contribution is obtained by means of a version of the original image which is spread-out in space and which is multiplied by a location-dependent weighting factor. By subtracting this scattered radiation image from the X-ray image, a corrected image with enhanced contrast is obtained. The estimate of the scattered radiation image is adapted to the adjustment values for the imaging parameters of the X-ray system.
