摘要
本文介绍了射线法CT 层析成象的基本原理,利用代数重建法进行图像重建的方法及在 IBM—PC微机上实现该算法的途径和框图。文章还讨论了影响图象质量的因素和处理方法。
With the aid of the graphic reconstruction by ART,the basic theory of CT by ray isgiven in this paper.The method on IBM-PC is introduced.The factors affecting the qua-lity of reconstructed graphics and the method about how to raise the quality of the gra-phs is also introduced.
