The Intelligent Data and Visualization (IDV) Desk is a system which combines numerical simulation with high-definition visualization and large data storage into a single desk. These three sub-systems are interdependent. They are connected to the network to get external information from various imaging systems and to provide data mining and data processing. The IDV desk is used in endovascular applications. The challenge is to provide to surgeon an interface to access all the data of interest at once on multiple displays. The interface must be friendly and very intuitive to the surgeon.
