摘要
ITK是一个对图像进行分割配准处理的开源的、基于对象的软件系统。它提供几乎所有的主流医学图像分割算法,能够解决虚拟手术中三维图像分割问题。讨论了ITK中区域生长和Level set分割算法,对CT序列图像进行分割,最后通过VTK对分割数据进行三维重建。利用ITK和VTK的功能集成,对医学图像三维组织体分割,并实现分割结果的可视化。实验证明这种方法能够满足医生对局部病变区域观测的要求,实时性良好。
ITK is an open-source, object-oriented software system for image processing, segmentation and registration. It supports almost all fundamental algorithms of medical image segmentation and can solve the problem of 3D medical image segmentation in virtual surgical system. In this paper it discussed the region growing and level set segmentation algorithms in ITK, and used them to segment the CT serial image. Finally the segmented 3D medical image is obtained by 3D reconstruction based on VTK. Integrating ITK into VTK can be applied to implement 3D medical image segmentation and 3D visualization. Experiments show that this method can meet the demand of surgeons to observe the local area of lesion with good performance of real-time.
