Abstract

Degradation of the aortic wall structure induces weakness in the vessel that can lead to the formation of aneurysms and the rupture of the vessel. Morphological characterization of the wall integrity is assessed by Optical Coherence Tomography (OCT) analysis. This technique allows inspection from the inside of the artery wall, focused on the media layer for this application. Degradation appears as spatial anomalies in the reflectivity profile due to non-uniform tissue composition and structure within surrounding healthy tissue. Wall degradation assessment is proposed by automatic identification of these anomalies. This procedure is aimed to surgical guidance during graft surgery interventions.
