Review on theories and methods of Ultrasound Computed Tomography

  • 摘要: <b<目的</b< 概述超声CT(Computed tomography)理论的发展过程中提出的的一些主要的理论和方法。 <b<方法</b< 分别对无散射条件下透射型超声CT、反射型超声CT以及衍射断层成像(diffraction tomography)的相关理论的研究目的、基本思想,以及相应的图像重建算法做了简要的概述,同时介绍了反散射(inverse scattering)问题在超声成像中的应用。 <b<结论</b< 由于超声传播的复杂性,各种超声CT理论都有其自身的成立条件,从而使得CT理论的应用范围有限。
    Abstract: <b<Purpose:</b< Prime theories and methods of ultrasound computed tomography (UCT) will be briefly summarized in this paper. <b<Method:</b< Here, we pay most attention to transmission-mode UCT and reflection-mode UCT under the condition that scattering is neglected,and diffraction tomography. The research purposes and principles of these theories are reviewed as well as image reconstruction method. In the end, we will introduce briefly the application of inverse scattering problem in ultrasonic imaging. <b<Result:</b< Although ultrasound computed tomography has receive more and more attention in medical imaging, it is only applied successfully to some soft issue, because the theories about it have strict existence conditions, such as weak scattering, etc.
