Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a method for tracking a bronchoscope by combining a positional sensor and image registration. Recently, very small elect-magnetic positional sensor has become available. It is possible to insert the sensor into the bronchoscope's instrument channel for obtaining bronchoscope camera's motion. However, the accuracy of its output is not enough for bronchoscope tracking. Combination of the sensor and image registration between real and virtual bronchoscopic images are quite useful for improving the tracking accuracy. Also this combination enables us to realize the real-time bronchoscope navigation system. We applied the proposed method to a rubber bronchial model. In the experimental results, the proposed system enables us to track bronchoscope camera motion in 2.5 frames per second.
