Comparison of Four Iterative Algorithm Based on Incomplete Projection Reconstruction

  • In emission computerized tomography and transmission computerized tomography, the analytic algorithm reconstruction used incomplete data will result in image artifacts in the result reconstructed. But the iterative algorithm would improve the quality of reconstruction images. In this paper, four type iterative reconstruction algorithm is applied to experimental sparse projections and limited-angle projections of the resolution test phantom. Their advantage and disadvantages are analyzed quantitatively. The study will provide the reference for the clinical or engineering application of the algorithm.
