Recovery of Truncated Projection using Non-iterative Extrapolation and Improvement of Image

비반복 외삽법에 의한 불완전 투명 데이터의 재생 및 영상의 개선법

An algorithm is suggested that truncted projection among the incomplete projections can be recovered from non-iterative extrapolation matrix by band-limited function. After the image being reconstructed from the recovered signals by non-iterative extrapolation, a known controur information and reprojection algorithm are used. It is shown that the reconstructed image using these algorithms is close to the original image. The effectiveness for these algorithms is proved by computer simulation.
