Claim 7:
8. A method of registering an airway to a three-dimensional (3D) model of the airway:
generating a 3D model of airways of a patient from images captured by a 3D imaging system;
generating virtual endoscopic images from the 3D model;
receiving an endoscopic image captured by an endoscope;
selecting, from the virtual endoscopic images, a virtual endoscopic image that corresponds to the endoscopic image, yielding a selected virtual endoscopic image;
determining a position of the endoscope in an airway, yielding a determined position;
determining that the determined position substantially corresponds to a location in the 3D model corresponding to the selected virtual endoscopic image; and
in response to determining that the determined position substantially corresponds to the location in the 3D model, displaying a location of the endoscope in the 3D model.
