    • Abstract
  • In this paper, a modified Tikhonov regularization CT image reconstruction algorithm from limited-angle was proposed.The modified Tikhonov regularization method adopted homotopy mapping to adjust the regularization parameter continuously, which increased the efficiency of computation procedure by avoiding the attempt of the regularization parameter.Experimental results show that the proposed algorithm improved the quality of reconstruction image by fixing on the optimization parameter rapidly.
