| 摘 要： | ART(algebraic reconstruction technique)算法是一种适合于投影数据采集量比较少的情况的图像重建算法。利用其进行图像重建时的主要工作是计算加权因子,该计算方法严重影响图像重建的重建质量和重建速度。讨论、研究并仿真了加权因子的三种计算模型,经比较分析最后得出了一种最优的重建模型。

| Abstract: | ART (algebraic reconstruction technique) algorithm is fit for data acquisition from incomplete projections. The main work is to solve of weight factor in ART algorithm and the computing method has a strong impact on the quality and speed of image reconstruction. Finally, by discussing, studying and simulating these three computing methods, an optimal reconstruction model is obtained through comparative analysis. |
