Abstract(in English) In laparoscopic surgery operator decides the insertion positions of a laparoscope and forceps by their experience and divination. In case of the laparoscopic procedure for D2 lymph node dissection in gastric cancer surgery, pancreas beside the splenic artery disturbs the surgery, so the insertion positions of the medical appliances are crucial. Therefore we developed a system to decide the insertion positions of the medical appliances preoperatively. By using this system, it is possible to decide the appropriate insertion positions preoperatively. To implement this system, it is necessary to reconstruct the three dimensional shapes of pancreas and splenic artery from CT images. In this paper, we propose segmentation algorithm of pancreas from CT images using multiple level sets and implement preoperative simulation system.
