Filtered backprojection implementation of the immediately-after-backprojection filtering
In an iterative image reconstruction algorithm, it was demonstrated that the contrast-to-noise ratio in the final reconstruction could be improved if a low-pass filter was applied to the backprojction of the projection-domain discrepancy, and then this backprojection was used to update the image fro...
