三维超声成像的发展现状及若干关键技术分析

Development Condition of Three Dimensional Ultrasonic Imaging and Analysis of Some Key Technologies

介绍三维超声成像的意义，不同的实现方案，并详细剖析了三维超声成像中遇到的图像定位、三维准确重构、不规则采样平面处理以及三维超声图像的分割问题。讨论了现有的发展水平及未来的发展方向。

This paper introduces the value of three dimensional ultrasonic imaging and it′s different realizing approaches. It deliberately analyzes the key techniques used in three dimensional ultrasonic imaging. These techniques include registration of two dimensional images, accurate reconstruction of three dimensional volume, projection of irregularly sampled plane and segmentation of three dimensional image. The development status and future trend are also given in this paper.
