本文对迭代重建算法的最新结果进行了综述。这些结果（其中许多尚未在其他地方出现）适用于基于级数展开方法的重建问题的非常一般的表述。阐述了一组优化标准和许多迭代重建算法，以及算法收敛到最佳图像的定理。将算法的功效与卷积方法的功效进行比较。特别是，证明了 ART 和反投影方法相同的说法是错误的。
In this paper a survey of recent results on iterative reconstruction algorithms is given. These results, many of which have not yet appeared elsewhere, are applicable to a very general formulation of the reconstruction problem based on the series expansion approach. A set of optimization criteria and a number of iterative reconstruction algorithms are stated, together with theorems on the convergence of the algorithms to optimum images. The efficacy of the algorithms is compared to that of the convolution method. In particular, the falseness of the claim that ART and the backprojection method are the same is demonstrated.
