| Abstract: | The problem of reconstructing images from incomplete projections is discuss-ed.The theorem shows that the positions and angles of incomplete projections play distinct roles in reconstruction.We apply these conclusions to the porcedu-res in reconstruction,especially the selection and rearrangement of data,the con-struction of effective algorithms as well as the control of artifects.The experi mental results teet and verify these conclusions. |
