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…

Approximation and Reconstruction from Attenuated Radon Projections
Yuan Xu, Oleg Tischenko, Christoph Hoeschen
Attenuated Radon projections with respect to the weight function are shown to be closely related to the orthogonal expansion in two variables with…
