Originální abstrakt

The paper presents creation of a 3D finite element model of AAA of an individual patient, based on its unloaded (reduced) geometry reconstructed from CT-scans. In most models pub-lished till now, the geometry of CT-scans is supposed to be unloaded while, in fact, a blood pressure is always acting in the aneurysm. Recent computer tomographs enable us to record the individual scans in a defined phase of the cardiac cycle, i.e. under a known value of the blood pressure. The paper presents a relatively simple method of how to find the unloaded geome-try that results in a shape corresponding to the CT scans when loaded by the original value of blood pressure. This process depends on the chosen constitutive model; isotropic hyperelas-tic constitutive behaviour of the tissues is supposed here.
