Tomographic Image Reconstruction from Incomplete View Data by Convex Projections and Direct Fourier Inversion


We consider the problem of reconstructing CAT imagery by the direct Fourier method (DFM) when not all view data are available. To restore the missing information we use the method of projections onto convex sets (POCS). POCS is a recursive image restoration technique that finds a solution consistent with the measured data and a priori known constraints in… (More)
