| Research Abstract |
In the conventional medical operation simulation system, it is difficult to realize the operation according to a patient as the organ model is made by hand By advancing of high-resolution digital image and computer assisted medical diagnosis (CAD), restoration of human body model of a patient from medical image and segmentation of each organ become possible. Then by translating the restored voxel model into tetrahedral one, implementation of not only deformation and abscission of organ with surgical instruments but also the haptic feeling an operator feels in the operation becomes possible. This research aims at developing a system to simulate the craniotomy clipping art and the coil embolectomya art ; the preventive measure of cerebral aneurysm rupture which is possible case of subarachnoid hemorrhage becoming problem recently. Real time development of necessary techniques using multi-core and GPU, Furthermore, by sharing the system between remote location, we are successful in making non-skill physician experience manipulation of a skilled physician and haptic sensation the physician feels in so doing.
