虚拟手术训练系统是伴随着虚拟现实技术的发展，在现代医学领域的崭新应用。该系统通过计算机仿真出在手术过程中的真实场景，主要用来完成帮助医学工作者的手术培训以及在手术实施之前对手术方案进行预演的作用。可以在很大程度上降低手术成本和保证手术实施的安全性。
防诈骗心得目前，国内外已经有很多机构在从事虚拟手术领域的研究，而本文则主要研究了虚拟手术训练系统的构建以及虚拟手术训练系统中的模型可视化过程。
本文所研究的虚拟手术训练系统平台是在Atamai软件框架基础上研发的。通过采用模块化的思想，将虚拟手术训练系统划分为各个独立的功能模块，利用Atamai框架和VTK可视化结构相融合的方法将功能模块嵌入到系统当中，搭建起整个虚拟手术训练系统的框架平台。通过白板模式解决了系统功能模块的扩展与删除，使整个系统不仅结构清晰而且具有较高的灵活性。
模型可视化作为虚拟手术训练系统中的关键技术，是所有其他功能实现的基础，本文利用Delaunay三角剖分算法，通过VTK的Pipeline结构实现了虚拟场景中的模型可视化，并利用三角网格的削减算法对可视化模型进行了优化，提高了系统的实时性。

Abstract
宛在水中坻
With the development of the virtual reality technology,virtual surgery training system has been ud in the modern medical field.It simulate a realistic scene during the operation by the computer.It is ud to train the doctor to do the operation and is also ud to practice the approach before operation.So it can mostly reduce the operation cost and ensure the curity of the operation.
At prent, there has been much institutions engaged in rearching the virtual operation. This paper mainly studies the construction of virtual surgery training system and model visualization in the virtual surgery training system.
沟通的名词解释The virtual surgery training system platform this paper studies is bad on the Atamai software framework. By the u of the modular thought, virtual surgery training system is divided into various independent function module. We embed the function modules into the system through the joint framework of Atamai and VTK,then we t up the entire virtual surgery training system platform. By the u of the white board model,we solve the problem

of module expansion and deletion.As a result, the training system has clear structure and high flexibility.
Model visualization is a key technology in the virtual operation training system.It is the foundation of
all other functions. We meet the model visualization function by Delaunay triangulations algorithm and VTK’s pipeline. We optimize the visualization model by triangular mesh cuts algorithm and improve the real-time performance of the system.
