Interventional planning and assistance for ascending aorta dissections
Résumé
In this paper, we present our actual works concerning interventional planning and assistance for ascending aorta dissections. The first part is about aortic dissection retrieval in Computed Tomography Angiography (CTA) images. It is based on fast marching segmentation, mathematical morphology and digital topology frameworks. The second part is about the registration of the outer aortic wall onto X-ray fluoroscopic angiographic images. It is based on either Digital Reconstructed Radiographs (DRRs) or parametric model projection, then on image transformation descriptors (ITDs) computing. Our motivation is first to give 3D views of dissecting aorta in peroperative step to assess the dissection, then to augment the current angiographic view by registering aortic dissection features during the intraoperative step to assist clinicians.
