Computer Environment for Interventional Neuroradiology Procedures

Abstract

This article addresses the design and development of a computer-based medical simulation system (NeuroCath) for training and patient-specific planning of interventional neuroradiology procedures. NeuroCath includes three main components: vascular extraction and modeling, instrument navigational simulations, and realistic human-computer interfaces. As the basis of the simulation, the vascular model is constructed from images obtained from different modalities such as X-ray, magnetic resonance imaging, and computerized tomography data. The model takes into account topological, geometrical, and physical properties of the patient’s vasculature. A finite element method–based physical model is constructed to simulate the behavior of interventional radiological instruments and devices within vessels during the interventional radiology processes. Realistic human-computer interfaces are provided in accordance with the actual interventional radiology environment. These interfaces include the video monitors displaying the simulated X-ray images and the haptic apparatus providing physicians with realistic tactile feedback encountered in the catheterization procedures.
