Abstract

The invention relates to a method and a device for the processing of X-ray images which can be used notably in medical fluoroscopy procedures since they keep the overall radiation load for a patient low. Processing of and detail enhancement in the X-ray images is preferably performed by means of a pattern matching algorithm which necessitates prior knowledge of a pattern of the detail of interest. In order to extract this pattern, at least one single image (HD) is formed (2) with a higher dose rate, said single image having an image quality which suffices for the automatic (4) or non-automatic (3) recognition of the pattern. The information extracted from this single image serves as a basis for the evaluation of X-ray images (LD2) formed with a lower dose rate.
