【摘要】 医学影像立体显示技术利用二维医学图像序列重建出三维模型,为医生提供了直观、全面、准确的病灶和正常组织信息,给临床诊断和治疗带来了巨大进步,是当今医学领域研究的热点。三维重建有体绘制和面绘制两种方法,本文主要介绍了面绘制方法的原理和实现,选择基于体素的表面重建方法,利用国际上广泛应用的可视化工具包VTK提供的MC算法实现面绘制,并对轴、冠、矢三个方向的任意切面进行显示。更多还原

【Abstract】 Medical image visualization technologies build 3D models with 2D medical image series to provide useful and precise informa- tion for the doctors. It is one of the crucial technologies in CAS system, Image Guide Surgery and Minimal Invasive Surgery. VTK is an advanced toolkit for the medical 3D visualization. 3D reconstruction has two ways of volume rendering and surface rendering methods. The content of the article introduces the principle and the realization of the method of mapping the surface, and through the MC algorithm of widely used internationally visualization tool kit VTK to realize the surface rendering.and display random sections from next three direc- tion: Axis、Crown、Arrow.更多还原
