| 摘 要： | 计算机断层成像(compuced tomography，简称CT)是一种先进的成像技术，它是在无损状态下获得被检物体断层的灰度图像．以其灰度来分辨被检测断面内部的几何结构、材质情况、缺陷种类等．是国际上公认的最佳的无损检测手段。本文首先介绍了计算机断层成像的基本原理，然后讨论了代数重建法，并给出了采用该算法的计算机仿真重建结果，最后指出了今后的研究方向。

| Abstract: | Computed Tomography is an advanced imaging technique, it can obtain gray image of the object's layer and does not destruct the object in the same time, it distinguish object layer's geometrical structure, material and defect type by gray, so CT is considered the best method to nondestructive testing. In this paper, the principle of CT is introduced ,the Algebraic Reconstruction Technique is discussed and the reconstruction results of computer simulation using this algorithm are shown, the research direction for furture is presented. |
