【摘要】 介绍了我们自行设计开发的一套用于手术导航系统的模拟实验和演示系统,可称之为模体演示系统。该系统用作演示或作为一个研究相关算法的实验平台,可实现模体的三维显示(包括模体的旋转、放大及缩小等)及手术工具的实时定位跟踪显示,其算法简单实用,基本上涵盖了手术导航系统的各种关键技术。首先阐述了其硬件系统的设计及软件系统的设计,并对其关键技术(三维定位器、坐标变换、匹配算法等)进行了详细的分析。更多还原

【Abstract】 A set of surgery navigation system’s simulation experiment or demonstrating system is introduced. It is called as Model Demonstration System and it is designed and developed by ourselves. The system can be used as an experiment platform to researching correlative algorithm or only for demonstration. It can show and trace the 3-D position of the model and surgery tools in real time. Its algorithm is simple and useful. The key technques of surgery navigation system are included in this Model Demonstration System. Hardware and software system designing are introduced as well. And the key techniques (for example 3D localizer, coordinates conversion, registration algorithm) of the system are explained in detail.更多还原
