Overview

This project involves a study of the diameter variation of abdominal aortic aneurysms (AAAs) over the cardiac cycle in vivo, a measure of the in vivo mechanical properties of AAA walls. Patient aneurysms are imaged non-invasively by ECG-gated MR Imaging, then mechanical properties of the aneurysms are determined from computational analysis of the imaging.
