An endoscopic surgical navigation system comprises a data acquisition subsystem, a tracking subsystem, a registration subsystem, a data processing subsystem and a user interface subsystem. The data acquisition subsystem inputs intra-operative scan data from a medical scanning device during an endoscopic procedure. The tracking subsystem captures data representing positions and orientations of a flexible endoscope during the endoscopic procedure. The registration subsystem determines transformation parameters for coregistering the intra-operative scan data and the data indicative of positions and orientations of the endoscope. The data processing subsystem coregisters the intra-operative scan data and the data indicative of positions and orientations of the endoscope based on the transformation parameters and generates real-time image data representing 3D internal views of a body that are coregistered with live video from an endoscopic video camera. The user interface subsystem receives input from a user for controlling the system and provides output to the user.
