Abstract
Computer-based simulators for surgical operations provide effective training and planning environments without danger to patients. A computer-based training simulator system for neuroendovascular treatment we have developed. In this paper, we focus on an approach for real-time deformation of devices such as catheters and guide-wires during navigation inside complex vascular networks. We have developed a mathematical model based on three-dimensional beam theory, combined with an incremental approach that allows for highly non-linear behavior using a linear model. Volume-based models constructed from 3D DSA or MR/CT images of a patient's brain for the vascular modeling we have adopted for the computationally efficient.
