Abstract
A distorted input image, produced by an X-ray exposure and composed of pixels defined by their position and their respective input image value, is transformed into a substantially distortion-free output image composed of pixels defined by their position and their output image value. Improvement is achieved in that the transformation utilizes a determination of the position of the corner points of the pixels of the output image (or the input image) as well as the surface area of a polygon defined by the corner points in the input image (output image).
