Abstract
A virtual internal cavity inspection system non-invasively provides images of cavities of a subject from a viewpoint within the cavity. An acquisition unit acquires imaging information about internal structures of a subject. This imaging information is segmented into separate structures, and a 3D surface model is constructed. An operator views an image of the 3D model to select a goal viewpoint and a start viewpoint. A viewpoint path is created linking the start viewpoint and the goal viewpoint. Images are created with a viewpoints along the viewpoint path. A variety of additional visualization techniques aid the viewer's localization of the current image viewpoint, and its relation to the subject.
