Most of patients die when thoracic aortic aneurysms rupture. The aneurysms are usually operated and replaced with aortic prostheses when their maximum diameter exceeds 5 cm. Because this criterion is based on the experiences, some aneurysms, which do not satisfy this criterion, may rupture. To estimate the possibility of the rupture and give the proper treatment to patients, it is necessary to find out the new criterion. Since the rupture has a close relationship with the stress in the wall, we have developed the method to construct three-dimensional finite element models of thoracic aortic aneurysms from MRI images.
