摘　　要：研究医疗诊断图像。针对计算机断层扫描图像CT和核磁共振图像MR I只能提供人体内部的二维图像,医生们只能凭经验由多幅二维图像去估计病灶的大小和形状,"构思"病灶与其周围组织的三维几何关系,给诊断带来了困难。为了使手术医疗诊断和治疗规划更准确。提出了设计和实现一个交互性的医学图像三维重建和可视化系统。首先给出了医学图像可视化算法原理;然后进行了三维重建可视化系统设计。最后以VC和VTK为开发工具设计程序,实现了CT文件的读取、图像数据的显示和基于MC算法和MS算法的三维模型的重建。仿真结果表明:既可以作为单独三维可视化系统用于医疗诊断,也可以针对不同手术的需要进行功能扩展,证明诊断图像显示更精确,为手术提供了科学手段。CT and MRI can only provide two-dimensional images.Doctors can use their experience to estimate the lesion size and shape from the pieces of two-dimensional images and imagine three-dimensional geometry relationship between the lesion and its surrounding tissue,which causes many difficulties in diagnosis.In this paper,an interactive medical three-dimensional visualization system was designed and realized to improve the accuracy,scientificity and interactivity of medical diagnosis and treatment planning based on image-guided surgery.Firstly,the medical image visualization algorithm principle was given;then a three-dimensional reconstruction visualization system was designed.Finally,the three-dimensional visualization programs were programmed to achieve CT file read,image data display and three-dimensional model reconstruction based on MC algorithm and MS algorithm by use of the development tools such as VTK and VC＋＋.The system has good operating performance and good human-computer interaction,which is designed based on modular for a single three-dimensional visualization system for medical diagnosis,or is added functions according to different surgery require.
