摘要
基于C型臂的手术导航系统是一种计算机辅助手术(CAS)系统。本文对此种系统的关键技术进行了研究。主要涉及XRII图像失真校正技术及C型臂成像系统标定技术。在此基础上,自行设计制作相关工具并开发软件系统。新鲜脊柱标本实验证明:与传统手术手段相比,在手术导航系统引导下的椎弓根螺钉植入精度更高。
C-arm based surgical navigation system is a kind of computer assisted surgery（CAS） system.In this paper,key techniques concerning this kind of system are presented.The key techniques mainly include XRII image distortion correction and C-arm imaging system calibration.On this basis,we designed relevant tools and made them fabricated,and developed a software system.Experimental results of human fresh spine sample showed that with the surgical navigation system,screw insertion accuracy was much higher than that without the surgical navigation system.
