Abstract
Thoracic aortic aneurysm is a common and lethal disease that requires regular imaging surveillance to determine timing of surgical repair and prevent major complications such as rupture. Current cross-sectional imaging surveillance techniques, largely based on computed tomography angiography (CTA) or magnetic resonance angiography (MRA), are focused on measurement of maximal aortic diameter, although this approach is limited to fixed anatomic positions and is prone to significant measurement error. The present techniques demonstrate novel approaches (generally termed herein 'Vascular Deformation Mapping (VDM)') for assessing changes in aortic dimensions. The present techniques quantify three-dimensional changes in the anatomic dimensions of a vessel through a process that involves non-rigid co-registration of serial imaging data and quantification of vascular deformation on a 3D surface model using some derivation of the spatial deformations resulting from the optimized spatial transform.
