US 6,647,093 B2 · Method and device for the processing of X-ray images

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.

Dependent claims

A method for the processing of X-ray images, the method comprising the steps of:

forming at least one X-ray image with a first dose rate which is higher than a second dose rate used to form at least one other image;
using the at least one X-ray image to process the at least one other image;
and
performing image processing using a pattern matching algorithm which utilizes at least one pattern of an image detail to be reproduced,
wherein the pattern matching algorithm utilizes an automatic pattern recognition procedure for deriving the pattern required for the processing of the at least one other image with the second dose rate from the at least one X-ray image with the first dose rate.
