本文介绍了我们的交互式介入心脏病学模拟系统（ICard）中的实时导管导航模拟。ICard旨在使医学生或医生熟悉介入导管插入术的技术。ICard软件提供血管的三维（3-D）视图和荧光透视图像，用于实时可视化导管位置。3-D人体脉管系统是从各种图像数据集构建的，并且用中心线层次模型表示。导管和导丝的导航及其与血管的相互作用通过应用有限元方法来实现。开发了以导管和导丝弹性为特征的物理建模，以提供导管插入术的真实模拟。系统中还开发了一种机电装置，允许对导管和导丝移动进行物理操作。ICard可用于介入心脏病学设备的培训和设计，并可进一步扩展用于预处理计划。
This article describes the simulation of real-time catheter navigation in our interactive interventional cardiology simulation system (ICard). ICard is designed to enable medical students or physicians to familiarize themselves with the techniques of interventional catheterization procedures. The ICard software provides three-dimensional (3-D) views of the blood vessels and fluoroscopic images for real-time visualization of the catheter position. The 3-D human vasculature is built from various image data sets and is represented with a central line hierarchy model. Navigation of the catheter and guide wire and their interaction with blood vessels are implemented by applying the finite element method. Physical modeling that features the elasticity of the catheter and guide wire was developed to provide a realistic simulation of catheterization procedures. An electromechanical device was also developed in the system, allowing physical manipulation of catheter and guide wire movements. ICard can be used for training and design of equipment for interventional cardiology and may be further extended for pretreatment planning.
