论文摘要
MUON射线照相技术是直射扫描成像方法的一部分,通常用于从检测器位置从径向方向上产生二维图像。但是,在文献中,已经有一些通过从不同观察点结合了几个测量值来制作的若恩层表的例子。本文中介绍的工作符合这一研究:通过MUON吸收放射线摄影测量值进行的,该靶标的靶标的是由非平凡几何形状排列的铅块组成的靶标。为了解决反转问题,采用了一种称为SART的迭代算法,获得了比使用卡方最小化更好的结果。
The muon radiography technique is part of the straight-ray scanning imaging methods and it is usually employed to produce two-dimensional images of the integrated density in the radial direction from the detector position. However, in the literature there are already some examples of muon tomographies made by combining several measurements from different observation points. The work presented in this article fits into this line of research: a tomography of a target composed of lead blocks arranged in a non-trivial geometry was carried out by means of muon absorption radiography measurements. To solve the inversion problem, an iterative algorithm called SART was employed, obtaining better results than using a Chi-squared minimization.
