| 摘 要： | 代数重建法(AlgebraicReconstructionTechniques,ART)适合于不完全投影数据的图像重建;其缺点是重建时间长,因而提高该算法的重建速度一直是研究的热点。本文对影响ART算法的几种重建模型进行了研究,并通过仿真数据分别对几种重建模型进行了成像数值实验。分析和比较了各种重建模型的重建速度和重建质量。

| Abstract: | The Algebraic Reconstruction Technique (ART) is fit for reconstructing image from incomplete projections; the disadvantage of ART is that the reconstructing is time-consuming, so improving the speed of reconstruction has been the focus of research. In this paper, several reconstruction models of ART are researched, the experiments of imaging reconstruction are made to these reconstruction models by using simulation data respectively. Analysis and comparison of these reconstruction models on reconstruction speed and reconstruction quality are given . |
