Abstract:
1. A method for assessing stent-graft attachment sites in a vessel prior to endovascular repair, comprising the steps of: (a) determining a radial endoluminal outlines in a cross sectional image of potential stent-graft attachment sites in said vessel; (b) determining an area of each one of said endoluminal outlines; (c) defining, for each one of said endoluminal outlines, a shape with substantially the same area as said endoluminal outline; (d) fitting said shape to said endoluminal outline; (e) calculating an irregularity index which is the ratio of at least a part of said endoluminal outline and the outline of said fitted shape corresponding to said at least a part of said endoluminal outline; and (f) visualizing said irregularity index with reference to a range of irregularities encountered in normal patients and in patients with a vascular disease.
