摘　　要：医学图像的可视化已成为基础医学研究和临床辅助诊断、治疗的重要手段,用计算机构建高度精密的人体各部位的三维模型已成为目前医学研究和疾病诊疗方法进一步发展的重要基础。Visualization Toolkit(VTK)作为一款流行的科学可视化软件,具有方便、高效的编程特点。采用VTK结合VC++实现医学图像三维可视化,分别采用Contour-connecting算法、Marching Cubes算法和Ray-casting算法进行了头部的三维绘制。结果证明VTK使用灵活,功能强大,具有重建步骤简单、速度快、交互能力强等优点,可以被广泛应用于医学图像的三维重建中。Visualization of medical images has become an important method for the basic medical research as well as clinical diagnosis and treatment. Construction of the highly sophisticated three-dimensional （3D） models of the human body by computers has become an essential foundation for current medical research and disease treatment methods. Visualization Toolkit （VTK） is a kind of famous software in scientific visualization fields. It is convenient and efficient for programming. This paper implements three typical algorithms, Contour-connecting, Marching Cubes and Ray-casting, of medical image 3D visualization using VTK with VC＋＋. Results show that VTK is a powerful tool with many advantages, such as simple operation fast, and good interaction ability and can be widely used in 3D reconstruction of medical images.
