Abstract

A computer-implemented method determines a geometric feature of a section of a blood vessel in an operating region. An image of the section is provided. An adapted blood vessel model is provided via image processing for the section by adapting a blood vessel model, which describes the section as a flow channel with a wall delimiting the latter and with an axis of symmetry. A centerline of the section of the blood vessel is determined as a contiguous pixel line. A relative spatial position of the side of the wall is ascertained based on the centerline and the image provided. The geometric feature is derived from the adapted blood vessel model. The disclosure also relates to a method for determining the length of a contiguous pixel line in an image and a system for determining a geometric feature of a section of an object.
