Quantitative branch information is also stored in the case of path trajectories in branching structures. The user can later request details of paths generated earlier in the interactive mode as well as view real-time endoscopic movies of these paths. Results obtained thus far have illustrated the usefulness of such a system. Endoscopic view represents the 3D surface view for a viewing site inside an arterial branch. A typical navigation path in the interactive mode is sketched on the Orthographic Projections Display.
Green line indicates navigation path.
Red dot denotes current viewing site. Viewing Site-Reference shows three mutually orthogonal image slices at current viewing site. Paths precomputed in the automatic mode are shown in red on the Mercator Reference Projection. The blue line on the Mercator Projection represents a artery branch selected by the user. The cross-sectional area at points along this path is plotted in the graph.
