This article presents a combination of well known image processing techniques to automatically segment CTA images of the Abdominal Aortic Aneurysm. Current results are that about 80% of the contours need no manual corrections. The remaining 20% fail due to calcified plaque close to the lumen border. After correction a 3D surface model is created from the 2D contours which is used as input for flow simulations and for parameter extraction of the AAA by clinicians for selecting the proper size and shape endograft, and to plan the placement procedure of this endograft in the patient.
