Modeling of Virtual Dense Elastic Object and Deformation using Haptic Device

In the recent years there have been various problems in medical treatments, of which the human error by the surgeon in an operation. In order to minimize the human error in an operation, we need a medical training system by which an inexperienced surgeon can try operating again and again to improve his skill. In our research, we set a goal to construct the medical training system, and in this paper, in order to achieve the goal, we approach to model a virtual dense elastic object and deform the object using a haptic device called PHANToM. Also we approach to enable high performance of rendering and deforming a virtual dense elastic object. A virtual dense elastic object is restored from CT or MRI to express each patient’s organs. PHANToM is used to express the force which is generated from a deformation of a virtual dense elastic object. In the system which we construct, we use two PCs to distribute the process of calculation, and SCRAMNet+ is used to connect each PC.
