DEVELOPMENT OF SURGICAL SIMULATION SYSTEM BASED ON 3-D IMAGES

重点研究了虚拟现实的快速交互功能，研究了手术仿真系统的开发。首先，我们开发了一个虚拟空间操作系统来交互操作三维图像数据。开发了移动、剪切、复制、移除、生成等基本功能。通过这些功能，医生可以将3D图像数据作为真实对象进行操作。作为评价髋关节手术仿真的重要功能，距离映射功能在系统中得到了很大的发展，虚拟现实技术具有革新手术仿真的潜力。对虚拟现实技术在医学领域的应用进行了综述，并对基于虚拟现实的三维空间交互系统进行了初步的实验。

We studied development of surgical simulation system paying attentions on fast interaction functions of virtual reality. First, we developed a virtual space manipulation system to operate 3-D image data interactively. As the basic functions, such as, moving, cutting, copying, removing and generation were developed. Through these functions, doctors can manipulate 3-D image data as real objects. A 3-D cursor function was also provided in the system.As the evaluation of surgical simulation of hip-joint surgery, distance mapping function is very important and developed in the system.Virtual reality technologies has a potential to innovate the surgical simulation. We surveyed papers on medical applications of virtual reality technology and made a preliminary experiment on the 3-D space interaction system based on virtual reality.
