Invention of intraoperative image navigation system during hepatic resection

我们的目标是开发一种在超声图像上引导肝内血管解剖的肝切除术导航系统。通过应用具有人脸识别功能的摄像头，我们试图开发一种在术中超声上绘制术前CT图像所计划的肝实质剥离线条的系统。超声与CT在图像质量上的完全不同，以及超声探头放置角度的问题，阻碍了超声对相应的CT血管结构的实时准确识别。提高形状或形态识别系统的质量是我们今后研究的首要问题。

We aimed to develop a navigation system for hepatectomy that guides the intrahepatic vascular anatomy on ultrasonography images. By applying the camera with face recognition function, we try to develop a system that plot the lines of hepatic parenchymal dissection planned by preoperative CT images on intraoperative ultrasonography. The complete difference in the quality of images between the ultrasonography and CT, and issues on the angles of putting ultrasonography probe precluded the accurate recognition by ultrasonography of corresponding vascular structures on CT at real time. To improve the quality of shape or morphology recognition system was suggested to be an issue of first priority in our future study.
