Purpose: Over last two decades computational methods for the analysis of the biomechanics of the vascular system have been developed, aiming at a better understanding of its physiology and pathophysiology and at clinical use as a tool for diagnosis and risk prediction of vascular diseases such as aortic aneurysms or plaque rupture. However, the benefit of such studies is currently limited by the lack of information on the patient specific material properties. In this work we employ blood pressure measurements and 3D ultrasound speckle tracking imaging to acquire the time resolved 3D displacement field of the abd…
