本文讨论了基于计算机的医疗模拟系统（NeuroCath）的设计和开发，用于介入神经放射学程序的培训和患者特定计划。NeuroCath包括三个主要组件：血管提取和建模、仪器导航模拟和逼真的人机界面。作为模拟的基础，血管模型由从不同模态（诸如X射线、磁共振成像和计算机断层扫描数据）获得的图像构建。该模型考虑了患者脉管系统的拓扑、几何和物理特性。建立了一个基于有限元法的物理模型，用于模拟介入放射学过程中血管内介入放射仪器和器械的行为。根据实际介入放射学环境提供逼真的人机界面。这些接口包括显示模拟X射线图像的视频监视器和为医生提供在导管插入手术中遇到的真实触觉反馈的触觉装置。
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.
