Max arch width	Max distance between DA and AA centers measured around the level of trachea carina
Mean radius	Mean of the oblique aorta cross section radii computed along the aorta, DA, Arch, AA regions
SD radius	Standard deviation of the oblique aorta cross section radii computed along the aorta
Centerline tortuosity	Measure of how much aorta centerline bends computed along the aorta, DA, Arch, AA regions
Centerline curvature	Mean curvature (directional change of the tangent vector) of the centerline curve computed along the aorta, Arch, AA regions
