From: An improved method for the removal of ring artifacts in high resolution CT imaging
Experimental results on uniform phantom with gold wire at the center of rotation. (a) Original Image, (b) zoomed view of ROI of corrupted image, and (c) ROI of corrected image obtained by the proposed algorithm. (for a-c C/W = 0.5/1). (d) uncorrected sinogram, (e) zoomed view of the band of stripes located at the center of the sinogram, and (f) corrected sinogram. (g) Plot of d(i) against detector position. Only the data window containing the band of stripes is shown here. (h) False detection of a single stripe at i = 1163 from plot of r(i).
