Enhancing angiograms

A method for enhancing angiograms, the method comprising:

• providing at least one angiographic image showing a vascular structure of interest comprising a plurality of vessel branches;
• determining at least one branch of interest from the angiographic image;
• segmenting the angiographic image for identifying possible branches of the vascular structure;
• selecting branches based on the identified possible branches and the determined branch of interest;
• estimating attenuation values of the selected branches;
• subtracting at least a predetermined part of the estimated attenuation values from the angiographic image generating a corrected angiogram;
• and
• providing the corrected angiogram.

A non-transitory computer-readable storage medium having stored instructions which, when executed by a processor, cause the processor to:

• obtain at least one angiographic image showing a vascular structure of interest comprising a plurality of vessel branches;
• determine at least one branch of interest from the angiographic image;
• segment the angiographic image for identifying possible branches of the vascular structure;
• select branches based on the identified possible branches and the determined branch of interest;
• estimate attenuation values of the selected branches;
• subtract at least a predetermined part of the estimated attenuation values from the angiographic image to generate a corrected angiogram;
• and
• provide the corrected angiogram.
