    • Abstract
  • In this paper,a new 3D iterative reconstruction algorithm for C-arm imaging systems from limited-angle of cone beam projections was proposed.The well-known FDK algorithm was adapted for C-arm imaging systems.Our approach was to introduce prior knowledge and regularizations(such as non negative,limited support) into iterative procedure.Experiments show that by our method,the streak artifacts can be greatly suppressed and the contrast can be significantly improved.
