Latest development of an interventional radiology training simulation system: NeuroCath

Abstract

We describe the latest development of a computer-based virtual reality environment for training interventional neuroradiology procedures. The system, NeuroCath (Neuroradiology Catheterization Simulator), includes extraction and construction of a vascular model from different imaging modalities that represents the anatomy of patient in a computationally efficient manner, and a finite element method (FEM) based physical model that simulates the interaction between the devices and neuro-vasculature. A realistic visual interface with multiple, synchronized windows and plenty of video control functions are developed. The latest version is also equipped with haptic feedback module that gives the sense of touch in real-time, and customizable vascular model so that trainer can understand the importance of vascular variations and practice. According to the validation in several clinical centers, 70%-75% of training features have been realized which makes the system well suitable for training of interventional neuroradiologists. © Springer-Verlag Berlin Heidelberg 2007.
