    • Abstract
  • The order of the applied projections in Algebraic Reconstruction Technique(ART) has a great effect on speed of convergence and accuracy in reconstructed image.In 3D cone-beam ART,some schemes of the sort of the projection sequence are compared in the paper.The schemes are listed below:Sequence Access(SAS),Multilevel(MLS),Prime Number Decomposition(PND),and Weighted Distance(WDS).The experiment results got by simulation experiment show that the speed of convergence on which reconstructed image by MLS,PND and WDS is more quick than by SAS,and the WDS is the best one in three sort schemes.
