Abstract
We present a method to simulate skin incision process at cerebral surgery planning system by X ray CT 3D-images. The cerebral surgery planning system consists of several parts. The first one of them must be skin incision, because operation begins with incising skin of head. Several years before our group have developed some methods to simulate opening skull and reaching tumor or other expected parts within head. The skin incision simulation can give information to doctor whether the incised skin disturb operation and if the incised skin will recover well after operation. But the simulation of shape change of soft tissue such as skin or brain and etc. have not been done yet. In this paper we simulate the skin incision process by using coordinate transformation and some other modification.
