Web1 Mar 2002 · The so-called Parker weights were applied to the FDK reconstruction algorithm and the image quality of the reconstructed images showed that CT numbers and … WebParker weighting is a weighting function that ensures that oversampled fan/cone beam data are weighted such that each line has unit weight. It is useful in analytic reconstruction methods such as FBP to give a more accurate result and can improve convergence rates for iterative methods. See the article Parker weights revisited for more information.
