Interventional planning and assistance for ascending aorta dissections

Abstract : In this paper, we present our global image processing framework of interventional planning and assistance for ascending aorta dissections. The preoperative stage of that framework performs the extraction of aortic dissection features in Computed Tomography Angiography (CTA) images. It mainly consists of a customized fast marching segmentation. The intraoperative stage of that framework realizes medical images registration and proposes data visualization enhancement; standard X-ray fluoroscopic images are used as the reference modality. We use our recently introduced registration method based on image transformation descriptors (ITDs) and usual 3D/2D techniques (based on digitally reconstructed radiographs). The first stage provides aortic dissection features and is to help clinicians for the planning. The second stage provides an augmented reality visualization and would be used for assistance during the intervention. As far as we know, this is the first complete image processing framework which focuses on the ascending aorta dissection (minimally invasive) endovascular treatment.
