Perspective volume rendered motion: gaining insights virtually.

Since modern imaging modalities deliver huge amounts of data the visualization techniques utilized must emphasize the structures of interest. To compare them, the different visualization techniques are regressed to a common ground whereby their strengths and weaknesses can be revealed. Perspective, lighting, color and motion support the real world look and feel. Virtual 3D techniques allow the observer to move through 3D images of anatomy almost in real time. In virtual cisternoscopy this concept is applied to 3D data of the head to reveal a closer look at the cerebral vessels. The more realistic presentation of the 3D data allows for higher efficiency.
