基于VTK的超声血管三维重建

3D Reconstruction of Ultrasound Blood Vessel Images Based on VTK

基于计算机数字图像处理、计算机图形学、虚拟现实和计算机网络等技术的医学图像处理与三维重建技术,已逐渐成为了一门具有特色的交叉学科。VTK(The Visualization Toolkit)是一个开源的、跨平台、可自由获取、支持并行处理的图形应用函数库。利用VTK强大的可视化功能对血管的超声医学影像进行三维重构,显示血管的内部切面,为医生提供更为直观的、精确的器官内部信息,协助医生观察体血管内部病灶,可以达到比较理想的效果。文章介绍了VTK的基本构成、可视化流程,以及基于C++语言在Microsoft Visual Studio2010环境下实现血管重建。

The technology of medical image processing and3D reconstruction based on computer digital image processing,computer graphics,virtual reality andcomputer network has gradually become an interdisciplinary subject.VTK,an graphics application library,which is open source,cross platform,and free toaccess.3D reconstruction of ultrasound blood vessel images based on VTK can do great help to the doctor with more detail of the inside of the organic.Thispaper introduces the basic constitution and visualization process of VTK.Furthermore,the reconstruction method of ultrasound blood vessel images based onC++is realized under the environment of Microsoft Visual Studio2010.
