医学图象三维可视化具有极大的医学研究和临床诊疗应用前景,是现代医学影象研究的重要领域.医学图象三维可视化方法通常分为表面绘制和体绘制,已有许多具体的算法提出.一些算法兼具表面绘制和体绘制的特点,归为混合绘制方法.该文概述了一些典型算法,并讨论了其特点及相互联系,同时对各类方法的应用场合及前景进行了分析和评价.

In this paper, the 3-D visualization algorithms to medical volume data are reclassified according to a clear hierarchy. Based on the traditional two algorithm classes-surface rendering and volume rendering, hybrid rendering is derived to become a new coexisting class. Volume rendering algorithms are especially classified from two points of view. About each class (or subclass) and its typical algorithms, we give a summarized description, and then generalize the characteristics and applications of them.
