Reconstruction from Radon projections and orthogonal expansion on a ball
Yuan Xu
The relation between Radon transform and orthogonal expansions of a function on the unit ball in $\RR^d$ is exploited. A compact formula for the partial sums of the expansion is gi…

Fast OPED algorithm for reconstruction of images from Radon data
Yuan Xu, Oleg Tischenko
A fast implementation of the OPED algorithm, a reconstruction algorithm for Radon data introduced recently, is proposed and tested. The new implementation uses FFT for discrete sin…
