Fig. 6From: A sinogram denoising algorithm for low-dose computed tomography Left: plots of the normalized MTF obtained by different sinogram denoising algorithms and those of the reference image and the image reconstructed without sinogram denoising. Right: plots of noise level versus spatial resolution for different denoising algorithms. The dashed horizontal and vertical lines in this plot show the corresponding values for the image reconstructed without sinogram denoisingBack to article page
