Existing sinogram restoration methods cannot handle noises and nonstationary artifacts simultaneously.
Although bilateral filter provides an efficient way to preserve image details while denoising, its performance in sinogram restoration for low-dosed X-ray computed tomography (LDCT) is unsatisfied.
The main reason for this situation is that the range filter of the bilateral filter measures similarity by sinogram values, which are polluted seriously by noises and nonstationary artifacts of LDCT.
In this paper, we propose a simple method to obtain satisfied restoration results for sinogram of LDCT.
That is, the range filter weighs the similarity by Gaussian smoothed sinogram.
Since smoothed sinogram can reduce the influence of both noises and nonstationary artifacts for similarity measurement greatly, our new method can provide more satisfied denoising results for sinogram restoration of LDCT.
Experimental results show that our method has good visual quality and can preserve anatomy details in sinogram restoration even in both noises and non-stationary artifacts.
