摘要
本文利用Tikhonov正则化方法、线性插值给出了Radon变换CHD反演方法的稳定化数值方法.克服了Radon变换CHD反演方法的不稳定性,且便于计算机实现.
By Tikhonov regularization method and linear interpolation,this paper gives a stable numerical method for the CHD inversion of Radon transformation. The method gets rid of unstability of the CHD inversion of Radon transformation and can be easily realizad on a computer.
