Image Reconstruction from Incomplete Data Using a New Data Acquisition Method

새로운 투영 데이터 수집방법을 이용한 불완전한 데이터로부터 영상 재구성

In computed tomography, the errors asociated with interpolation in the reconstruction process degrade the reconstructed image and may cause divergence unless a large number of rays is used. A new data acquisition scheme without interpolation is developed in this paper. Samples (projection data ) are taken in phase with samples of the Cartesian grid to eliminated errors associated with interpolation process.
