| 摘 要： | 为了解决不完全投影情况下的ICT图像重建质量不高和重建速度较慢的问题，文中介绍了两种以代数重建思想为基础的CT图像重建算法：基于共轭梯度法的快速迭代算法和多约束准则的遗传算法。经过实验验证，这两种算法能够在投影数据不完全的情况下，重建出令人满意的图像。

| Abstract: | In order to improve the quality and solve the problem of low speed of image reconstruction in the traditional industrial computed tomography(ICT)when the data have been acquire is incomplete projection,tow algorithm about the steepest descent,the fast conjugate gradient and the multiple constrained of genetic algorithm based on algebraic it erative were proposed.Experiment results clearly demonstrate that algorithm reconstruction technique can efficiently improve quality of images reconstruction when processing the incomplete projection data. |
