| 摘 要： | 概述超声散射CT（computed tomography）理论的发展过程,分别对X射线CT技术、医学超声CT技术、无散射超声CT技术及超声衍射CT技术相关理论的发展、基本思想及优缺点进行了概述,介绍了主要用于工业超声CT检测的超声散射CT技术的基本概念,特点及意义等。散射超声CT技术不仅不需要反投影重构,而且在一定程度上弥补了线性超声CT方法由于线性假设或弱散射假设带来的不足,具有广阔的应用前景。

| Abstract: | The development process of ultrasound computed tomography(UCT) will be briefly summarized and we pay most attention to X-ray CT technology,medical ultrasound CT technology,ultrasonic non-scattering CT and ultrasound diffraction CT technology.The research development and principles of these theories are reviewed as well as advantages and disadvantages.In the end,we will introduce briefly the ultrasonic scattering CT which is mainly used for industrial ultrasound CT.Introduces the basic concept,the characteristic and the meaning of ultrasonic scattering CT.Scattering ultrasound CT technology not only don’t need back-projection reconstruction,but also makes up for the shortage of the linear ultrasonic CT method in some degree because of linear assumption or weak scattering assumption.So it has wide application prospects. |
