Virtual reality based 3D Guidewire Propagation Simulation for Endovascular Intervention
Virtual reality based simulation of the motion of guide wire and catheter inside human vascular structures can benefit a lot for the training, pre-operation plan and intra-operative assistance used to improve the accuracy and quality of endovascular intervention, it also facilitates the choice of suitable guide wire and catheter with the simulation of its material property such as torque, rigidity, elasticity. In this paper, we proposed a fast and well performed collision cancellation algorithm based on geometric analysis and angular propagation, and developed a 3D real-time interactive system for the simulation of guide wire and catheter motion inside specific patient vascular. The guide wire or catheter is modeled as “multi-body representation and the properties are defined by its intrinsic characteristics. The motion of guide wire or catheter inside vascular is guided by collision detection and collision cancellation algorithm. Finally, a relaxation procedure is applied to achieve more realistic status. The preliminary experimental results show that the behavior of the guide wire or catheter depends on the defined parameters, and the real time simulation could be achieved, thus the simulation system is effective and promising.
