椎弓根进钉通道数字化分析研究

Digital analyses to create path for screw inplanting in vertebrae

脊柱椎弓根内固定技术是恢复脊柱形态和功能的重要手段,如何安全有效地植入螺钉一直是临床应用研究十分关注的课题,本文将医学影像和医学三维重建技术与逆向工程技术结合,通过获取CT连续断层图像,重建椎骨三维数字解剖表面模型,应用逆向工程技术对三维数字解剖模型进行数字化三维定量分析与设计,探索建立定位、定量研究椎弓根进钉通道的方法,从椎骨整体三维空间上获得准确的进钉通道数据。

vertebrae fastness is an important method to rehabilitate vertebrae structure and function,How to inplant the screw safely is a focus in clinic cure.The medical image and 3D model rebuilding is combined with reverse engineering,the vertebrae 3D model is constructed by CT image,the precise path to inplant the screw in vertebrae is obtained in 3D digital model,the method to create path for screw inplanting in vertebrae is researched.
