This paper discribes the endobronchial ultrasound navigation system. This system visualizes the location of an ultrasound probe and the area captured by an endobronchial ultrasound image on real or virtual bronchoscopic views. To overlay ultrasound images on real or virtual bronchoscopic images, it is required to obtain transformation matrices. Firstly we estimate transformation matrices which represent relationships between bronchoscopic camera image and ultrasound image coordinate systems and between CT image and ultrasound image coordinate systems. Then we overlay ultrasound images on real or virtual bronchoscopic images by using transformation matrices obtained in the previews step. We evaluated the accutacy of transformation matrices. The experimented results showed that the registration errors were 10.63 pixels and 1.08 mm in average. Also it was possible to overlay ultrasound images at appropriate positions. |
