摘要
医学体数据三维可视化技术有着广泛的应用前景。近年来为加快绘制速度、提高成像质量和节省存储空间提出了许多改进算法,本文讨论了医学图像三维表面绘制的两种重建方法及基本原理,并通过比较这两种重建方法对应的几种算法实现的复杂度、实时显示情况等,总结出各自的优势和弱点,分析不同情况下如何选择算法。
The 3-D Visualization technique on medical volume data has extensive application and broad prospects. In order to quicken the rendering speed, improve the quality of image quality and save the memory space, many improved algorithms have been proposed in recent years, this article has discussed two methods for the medicine images three dimensional reconstruction and its basic principle, and through comparing with these two kinds of reconstruction methods correspondence of several algorithms realizing complexcity, the real time displaying situation and so on, summarized respective surperiority and weakness, analysis how to choose the algorithm in the different situation.
