Abstract
We demonstrate the added utility of virtual-bronchoscopic techniques for assessing major airway obstructions. Shaded-surface displays of the major airways are combined with tube-geometry analysis of the airway lumen to assist in the study of 57 subjects. In tandem with this study we also propose a method for automatically finding the centerlines (central axes) of the major airways. The method runs quickly on a typical anisotropically sampled 16-bit high-resolution CT image and has potential for providing useful guidance information for virtual bronchoscopy.
