• Its image reconstruction belongs to the image reconstruction under narrow fan - beam scan mode . after comparing different algorithms , this paper introduces convolution back projection algorithm for the parallel image reconstruction
  采用高能直线加速器作为射线源的高能x射线工业ct机多采用窄角扇束扫描方式，其图像重建属窄角扇束扫描方式下的图像重建。
• When x - ict detects large industrial parts and requires high resolving power , image reconstruction of x - ict has huge pixel matrix and the amount of calculation increases greatly resulting in much more time of image reconstruction . this paper proposes the parallel image reconstruction based on workstations cluster to solve fast image reconstruction of high power x - ict this paper presents the relevant basic theories and principles of ict and image reconstruction , including scan mode and image reconstruction algorithm . high power x - ict which adopts powerful beeline accelerator as radial source often uses narrow fan - beam scan mode
  工业ct机检测对象为大型工业构件并且要求高分辨率时，图像重建的像素点阵巨大，计算量大大增加，从而图像重建时间过长。本论文提出用在工作站机群上的多机并行工作的并行图像重建解决高能x射线工业ct机的快速图像重建问题。本论文介绍了工业ct和图像重建的基本理论、基本原理等有关内容，包括扫描方式和图像重建算法。
