Double-Filtration Algorithm for Two-Dimensional Tomography

摘要

A new algorithm for two-dimensional tomography is suggested and investigated. In con-trast to the other algorithms, in this both the projections and the two-dimensional image are filtered. Numerical simulations are performed, which show that for a small number of projections the double-filtration algorithm provides higher reconstruction quality than the filtered backprojection method, in particular, the Shepp-Logan algorithm.
