Method for Brightness Adjustment of an X-ray Image, X-ray Device, Computer Program and Data Carrier

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for correcting uneven brightness in X-ray images caused by filters that attenuate X-rays differently across different regions. By using specific algorithms and image processing techniques, the method analyzes the boundaries between these regions and automatically adjusts the brightness, creating a more uniform X-ray image.

Patent Abstract

A method for adapting the brightness of an X-ray image is provided. The X-ray image is recorded using a filter attenuating X-ray radiation used for recording the X-ray image differently in at least two spatial filter regions. The method includes determining image regions mapping the filter regions from filter parameters and recording geometry parameters describing the filter regions from at least one evaluation line running perpendicular to a boundary between image regions. The method also includes determining, for each evaluation line, a correction value describing a difference in brightness between the image regions from an image value profile along the evaluation line in an evaluation area containing the boundary, determining at least one correction factor from the at least one correction value, and adapting the brightness between the at least two image regions by scaling the image values with the correction factor.
