Geometrical and hemodynamical features of the internal carotid artery (ICA) of 50 subjects diagnosed with a cerebral aneurysm along the ICA. Measured features were the radius and its derivative, the centerline curvature, the wall-shear-stress and its derivative and the torsion. After alignment and smoothing pre-processing steps, each feature was evaluated onto the same 512-point uniform 1-dimensional grid of curvilinear ascissa. Subjects were divided into two groups pertaining to different clinical severity of the aneurysm:
25 subjects affected by a severe form of the pathology (patients with an aneurysm in the upper part of the ICA),
25 subjects affected by a minor form of the pathology (patients with an aneurysm in the lower part of the ICA) or healthy (without any aneurysm).
