| Abstract(in English) | In this paper, we describe a method which we can identify 3D position and direction of ultrasound scanning prove inserted into inside of the body, which gives endoscopic images. We use marker transducers placed on surface of the body, which transmit pulse synchronized to the ultrasound scanner. This method can also be applied to navigation of inside the body. In further, the method measuring position (direction and distance between scanning probe inside of body and transducer outside of body) of marker on the scanned image obtained with ultrasound endoscope by using adaptive threshold and robust algorithm is described. This system can be extended to for inside-body navigation by localizing outside-body transducers and visualizing the position and trace of the inside-body ultrasound probe. The final goal of the system is to reduce the X-ray does in the endoscopic examination and to give direct 3D localization instead of the conventional 2D X-ray fluoroscopy. |
