摘要
本文介绍了图像重建技术的基本思想和方法,提出了迭代卷积反投影重建法和利用非完全投影进行数据修复法.实验结果表明,该算法具有运算速度快,收敛性好,有较高的重建精度和空间分辨率.
The principle of image reconstruction is briefly introduced. In this paper, the reconstructive method of iteration convolutive inverse projection is proposed and for improvine precision, way of data recovery based on nonconplete projection is used. The experimental results show that the algorithm has fast computine speed, good convergence character and high reconstructive precision.
