Abstract: Various methods and a system for the display of a luminal organ are presented. In exemplary embodiments according to the present invention numerous two dimensional images of a body portion containing a luminal organ are obtained from scan process. This data is converted to a volume and rendered to a user in various visualizations according to defined parameters. In exemplary embodiments according to the present invention, a user's viewpoint is placed outside the luminal organ, and a user can move the organ along any of its longitudinal topological features (for example, its centerline, but it could also be a line along the outer wall). In order to explore such an organ as a whole, from the outside of the organ, a tube-like structure can be displayed transparently/semi-transparently and stereoscopically.
