Determination of vessel geometry and flow parameter

A computing device comprising:

• a processing unit;
• and
• a memory comprising program code, wherein the processing unit, when executing the program code, is configured to:
• receive a plurality of images of vessels, the plurality of images being obtained from different viewing angles relative to the vessels;
• determine, in each image of the plurality of images and for a first vessel of the vessels, a distance of different points along the first vessel relative to a reference location at the first vessel;
• determine, in each image of the plurality of images, and at each of the different points, a parameter of the first vessel for blood flow through the first vessel;
• provide, for each image of the plurality of images, a data sequence indicating the parameter relative to a distance to the reference location;
• carry out a sequence alignment of the data sequences obtained for the plurality of images providing aligned data sequences;
• determine an aggregated representation of the first vessel based on the aligned data sequences;
• and
• determine a flow parameter for the first vessel from the aggregated representation.
