Abstract

This paper concerns the relationship between the geometry of the Inner Carotid Artery, as described by its centerline curvature and its radius, and the location of the aneurysm for the AneuRisk65 data. Fisher Rao curve registration is used to align the curvature of the artery, and this alignment is then used to register both the curvature and the radius profiles. Based on this alignment, interesting results are found regarding the discrepancy between the arteries of patients with aneurysms at or after the terminal bifurcation (upper group) and the arteries of subjects with aneurysms before bifurcation, or without aneurysms (lower-no group).
