摘要
工业CT ,是在无损状态下获得被检断面的二维灰度图象 ,以图象的形式展现被检物体内部的结构特征。在介绍了工业CT的几种扫描方式的基础上 ,较详细地分析了窄角扇束扫描方式下的数据重排方案。
ICT is the acquisition of two-dimensional gray-scale image of the detected fractured surface under non-destructive condition and the display of inner structural features of the detected objects in images. On the basis of introducing several ICT scanning methods, this paper analyses in detail the data-rearranging plan when the method of narrow-angle sector scanning is used.
