iart造句

• In this paper, two novel algorithms of reconstructing high resolution images from both overlapped parallel projection data and overlapped fan beam projection data with low resolution are presented . one is called virtual detector algorithm, and the other is direct reconstruction algorithm . both of the algorithms with two forms for the parallel data and fan beam data respectively are developed based on the interpolative algebraic reconstruction techniques ( iart )
  本文在研究插值代数重建法(iart)的基础上，根据特别设计的数据采集模式(平行相叠采样和扇形相叠采样)，提出了由相叠低分辨数据重建高分辨图像的两个新算法，即虚拟探测器法和直接重建法。
