摘要
在分析医学体数据三维重建基本过程的基础上,介绍了光线投射法、足迹法、错切-变形法和基于小波变换的体绘制等典型算法,讨论了各类算法的优缺点以及改进方向,并展望了医学体数据体绘制技术的未来研究方向。
In three-dimensional reconstruction of Medical Volume Data, Volume Rendering is one of the most hot technologies.After analysised the basic process of three-dimensional reconstruction of medical data,this paper introduces the typical volume rendering algorithms, such as ray-casting algorithm,splatting algorithm,and a algorithm based on wavelet transform.we discusses the advantages and disadvantages of above slgorithms and proposes the corresponding solutions about the disadvantages. Finally, the directions of research in the fu- ture are introduced.
