Abstract
The present invention relates to image processing of angiograms. A device for enhancing angiograms is provided. The device comprises a data input, a data processor, and an output interface. The data input provides at least one angiographic image showing a vascular structure of interest comprising a plurality of vessel branches. The data processor is configured to determine at least one branch of interest from the angiographic image, to segment the angiographic image for identifying possible branches of the vascular structure, to select branches based on the identified possible branches and the determined branch of interest, to estimate attenuation values of the selected branches, and to subtract at least a predetermined part of the estimated attenuation values from the angiographic image to generate a corrected angiogram. The output interface is configured to provide the corrected angiogram.
