Abstract
A correction method is used for reducing artifacts caused by structures of high x-ray absorption in computer tomography images. By such a method, it is possible for interfering objects to be found both automatically and interactively in a computer tomography image. Relatively large interfering objects are preferably split up into a plurality of smaller interfering objects. The computer tomography image for each pixel of a selected image region is filtered as a function of its position relative to the interfering object.
