摘要
介绍了由投影重建图像的基本原理,对扇束滤波反投影重建算法进行了分析,并针对该算法的特点提出了一种提高算法求解速度的方法。最后对所提方法进行了实验,并给出实验结果。
In this article, the basic principle of reconstructing image from projection is introduced. The fan-beam filter back-projection algorithm is analyzed,and according to the characters of this algorithm,a method to accelerate the running speed of this algorithm is proposed. Finally the method is tested by experiment and the results are shown here.
