A new linogram algorithm for computerized tomography
Daniel Potts,Gabriele Steidl +1 more
TL;DR: A new linogram algorithm is proposed for the high quality Fourier reconstruction of digital N x N images from their Radon transform that requires only O(N 2 log N) arithmetic operations and preserves the good reconstruction quality of the filtered backprojection.
Journal ArticleDOI
Quadrature Errors, Discrepancies, and Their Relations to Halftoning on the Torus and the Sphere
TL;DR: This paper generalizes the approach by considering quadrature error functionals on reproducing kernel Hilbert spaces (RKHSs) with respect to the quadratures nodes, where it turns out that the original attraction-repulsion functional was wrong.
Proceedings ArticleDOI
New Fourier reconstruction algorithms for computerized tomography
Daniel Potts,Gabriele Steidl +1 more
TL;DR: Two new algorithms for high quality Fourier reconstructions of digital N by N images from their Radon transform are proposed, based on fast Fourier transforms for nonequispaced data (NFFT) and require only O(N2 log N) arithmetic operations.
