Novel, Inverse Biomechanical Methods Supporting Abdominal Aortic Aneurysm Management

Abstract

Clinical treatment of abdominal aortic aneurysms is decided mainly on the maximal dilatation diameter. Biomechanics based criteria calculated by numerical fluid structure interaction simulations on patient specific geometries are superior to that approach, but are extremely time and resource consuming and require high expertise, furthermore they fail to incorporate the real, inhomogenous material parameters. Our method, summarized in this paper, handles these shortcomings by introducing a novel, indirect, in-vivo, patient-specific inverse material parameter identification method.
