The Study and Analysis of Fast Iterative Algorithms in Industrial Computerized Tomography Image Reconstruction

Iterative Algorithms can obtain good reconstruction image for enough Iterative times in the technique ct image reconstruction. The order method of the Weighted Distance Orthogonal (WDO) is introduced in this paper to accelerate the Iterative reconstruction, which improves greatly the access mode of ART to projection data, based on the crucial effect that the access order of projection date has on reconstruction quality and speed in algebraic reconstruction technique. The method speeded up image reconstruction and improved the quality as well in large scale by using information relation of radial traversing pixels in consecutive orthogonal projection angles.
