Reduction in differences between reconstructions of the round-robin dataset (slice No. 896). (Top three rows) Slice reconstructions using different implementations. Reconstructions were performed by discarding every second projection from the full dataset. The right halves of the images show absolute differences with the corresponding strip kernel reconstruction in each set. The rightmost column shows pixelwise standard deviations in each set. (Bottom row, left) Histograms of standard deviation for all three types of filters. (Right) Mean standard deviations in slice S = 896 for different numbers of projection angles. |
