Upper row, Aneurysm extraction for pre- and poststent acquisitions (A.1 and B.1), their 3D velocity fields (A.3 and B.3), and their systolic Velan values, respectively. The extraction method is illustrated in A.2, where the aneurysm bulge is isolated from the parent artery by removing all the mesh cells within a diameter Dvessel +1 mm around the center line. B.1 and B.2, The conebeam CT of the implanted Silk (radio-opaque markers segmented in blue) is registered with the 3DRA geometry to show its clear separation from the extracted aneurysm. Lower row, QICAs (C.3) measured on orthogonal planes positioned along the vessel center line (C.1), with partial volume correction (C.2) as described in Bouillot et al.24
