摘要
用投影重构图像技术,从医学CT到非破坏性工业测试的众多领域中都得到应用。常见的代数解法,卷积算法及滤波——逆投影法,计算相当繁琐。该文提出的方法,仅需做加(减)和除2运算,就可以在平行和聚焦的投影中,逐个得到像素的值。
The method of digitally reconstructing an image from its projections has been applied in many areas from CT to non- destructive test of industry.But the algorithms of algebraic reconstruction techniques are too complicated.Using some additions （subtractions） and divided by 2 the gray levels of pixels can be got easily one by one,from their parallel and focused projections,by the method presented here.
