Results
Other related information The differences between the simulation plane and the authentic plane were conventionally investigated after dividing the surrounding ligaments laparoscopically. The authentic dissecting plane was estimated by a staining method with contrast-enhancement ultrasonography and near-infrared ray vision system (Photo Dynamic Rye(R), HAMAMATSU Photonics). The differences were measured as a request of errors detected every 5 degrees of the plane image from the center in in a real excision domain.
