Abstract
Virtual reality system for Minimally Invasive Surgery (MIS) is a challenging problem in the context of the World Wide Web. In this paper, we present a framework of web-enabled interventional neuroradiology simulation system with force feedback. Based on the hierarchical information from segmented human vascular images, we produce the small datasize control mesh of the vasculature and finally get a smooth vascular model. When a collision occurs, we calculate the volume of force feedback according to physical parameters under which the collision occurs and give the trainee a haptic feedback by the force feedback hardware that connects to the simulation system. Our method has three features: 1) the vascular model exhibits little memory consumption; 2) the vascular model delivers good rendering performance; 3) the collision detection along with force feedback computation model is a distributed one and can provide good real time reaction to the user. The initial result obtained from applying the method in our prototype of a web-enabled simulation system is encouraging: the 3D visualization of human vasculature and the haptic feedback mechanism present the trainee a vivid surgical simulation environment and the real-time force reaction is also an exciting feature for web-enabled surgical simulation system.
