The convolution back projection algorithm based on windows function

摘要

In this paper, some efficient image reconstruction algorithms in industrial computed tomography with the fan-beam projection based on windows function was discussed in detail. In order to improve the quality of image reconstruction, windows functions of image reconstruction of convolution back projection was proposed. The windows functions method ameliorates the process of image reconstruction. The efficiency of windows function is evaluated in contrast to that of its traditional serial counterpart. Experiment results clearly demonstrate that windows function can efficiently improve quality of images reconstruction.
