肝脏及内部管道的可视化和三维交互式测量

摘要

The study of 3-dimensional (3D) visualization of liver and its internal piping is important to hepatobiliary surgery.Based on the common 2D device,a system is designed for 3D interactive controlling according the analysis of the dispatching and processing of the VTK messages.In this system,the distance between liver and its internal piping can be conveniently measured in any directions,which can effectively resolve the shortcoming of distance measuring in appointed planes and improve the accuracy of measuring,so it has a wide application area of aided clinical diagnosis,surgery plane and medical research,etc.%对肝脏和内部血管进行三维重建和三维空间距离的测量对于肝胆外科有重要的意叉.在对VTK(消息传递和处理进行分析的基础上,基于当前的二维设备,设计了一个可视化和三维交互式控制的距离测量系统,能够直观地观察体数据的各个截面,同时实现对肝脏及内部管道之间三维空间距离的测量,克服了当前系统中只能够在某个固定的平面上测量的缺点,有效地提高了测量的精确度,在辅助临床诊断、手术规划和医学研究等领域中有较好的应用前景.
