Our goal is to provide a means of enabling minimally invasive therapy within the ascending aorta as a standard clinical procedure in case of aortic dissections. Exact knowledge of the inner and outer surface lengths of the ascending aorta (AA) is essential for producing patientspecific stent-grafts in order to avoid interference with any of the branch vessels connected to the AA. This contribution introduces a genuine approach to quantifying these key parameters. Furthermore, we employ an unique and precise result validation, namely by comparing the accuracy of the inner and outer curvature lengths, determined within a cadaveric CT dataset, with manual measurements performed by a vascular surgeon on the body donor’s excised aorta. Our validated scheme is also being applied under identical circumstances on three patient datasets in pursuance of assessing the variability pertaining to human aortic pathological morphology.
