Paper Abstract

Past work has shown that guidance systems help improve both the navigation through airways and final biopsy of regions of interest via bronchoscopy. We have previously proposed an image-based bronchoscopic guidance system. The system, however, has three issues that arise during navigation: 1) sudden disorienting changes can occur in endoluminal views; 2) more feedback could be afforded during navigation; and 3) the system's graphical user interface (GUI) lacks a convenient interface for smooth navigation between bifurcations. In order to alleviate these issues, we present an improved navigation system. The improvements offer the following: 1) an enhanced visual presentation; 2) smooth navigation; 3) an interface for handling registration errors; and 4) improved bifurcation-point identification. The improved navigation system thus provides significant ergonomic and navigational advantages over the previous system.
