Kai Ostendorf, Domenico Mastrodicasa, Kathrin Bäumler, Marina Codari, Valery Turner, Martin J. Willemink, Dominik Fleischmann, Bernhard Preim, Gabriel Mistelbauer
2021
In this work, we investigate different shading styles for the visualization of the aortic inner and outer wall, including the dissection flap.  ...  Current blood vessel rendering usually depicts solely the surface of vascular structures and does not visualize any interior structures.  ...  Modeling and visualizing multiple vessel wall layers is primarily important in large vessels and paramount for blood flow simulations [BVS * 20] as well as rupture risk assessment of aneurysms [GLH * 14  ...
