Abstract

The standard procedure for diagnosing lung cancer involves 3D computed-tomography (CT) assessment, followed by interventional bronchoscopy. In general, the physician has no link between the CT assessment results and the follow-on bronchoscopy. Thus, the physician essentially performs bronchoscopic biopsy of suspect cancer sites blindly. We have devised a computer-based system that greatly augments the physician's vision during bronchoscopy. The system uses techniques from computer graphics and computer vision to enable detailed 3D CT procedure planning and follow-on image-guided bronchoscopy. The procedure plan is directly linked to the bronchoscope procedure, through a live fusion of the 3D CT data and bronchoscopic video. During a procedure, the physician receives considerable visual feedback on how to maneuver the bronchoscope and where to insert the biopsy needle. We have performed a series of controlled phantom and animal tests, in addition to using the system on a large number of human lung-cancer patients. Results indicate that not only is the variation in skill level between different physicians greatly reduced, but that their accuracy increases.
