Abstract

The purpose of this study is to introduce a general form for linear recursive image reconstruction using measurement and estimation matrixes. The convergence condition of presented algorithm is proved analytically and illustrated by simulation results. Previous presented recursive algorithms are fitted in our general form. Filtering in reconstructing duration is introduced new form to increase speed of the processing task. Finally forward projection and back projection as a spatial case are proposed and simulated.
