Abstract

We developed intraoperative 3-dimensional (3D) echoic image using the information of 2-dimentional echo and image analyzing system (SAS-200). The principle of SAS-200 is that magnetic field sensor, which is setting on echoic probe, recognize the position of the probe as 3D coordinate. This method was adopted to the patients with liver tumors and the donors for living-related liver transplantation. Using this method, the relation between a main tumor and feeding vessels was visualized as 3D-US image.A 3D-US image was useful to make an accurate navigation for liver surgery.
