摘要 用矩阵方法研究数字重建编码成像的迭代方法。为克服问题的不唯一与病态,采用正规化方法,给出正规化迭代解码算法,分析了算法的收敛性、与真解的关系,所得的正规解可以抑制噪声,但不能完全反映物体的局域性质。文中分析了算法的计算复杂性。 The iterative algorithm of digital reconstruction of coding imaging is studied by matrix analysis. We use regularization method to overcome the ill posed problem. The convergence and error of the algorithm is studied. It is shown that the nosie can be compressed, but some local structure is distorted. The computation complexity of the algorithm is analysed.
