Visualization of cerebral blood vessels

In order to enhance the cerebral blood vessels in the visualization, in this report, the specific problems of the medical diagnosis of vascular structures and the requirements of the visualization are presented. The most suitable shading model to outline the vessel features is defines and a new visu...
