Abstract

This paper proposes a sequential image reconstruction algorithm for the exact reconstruction of an image from a limited number of projection angles. Specifically, four projection axes oriented at coprime ratio view angles are used. The set of proper values for the view angles as well as the overall number of samples on the projection axis are explicitly defined and are related only to the dimensions of the image. The slopes of the four projection axes are calculated according to the chosen view angle and are symmetrically oriented with respect to the horizontal and the vertical axis. The reconstruction is a non-iterative, one pass process based on a decomposition sequence which defines the order in which the image pixels are restored. Several simulation results are provided that demonstrate the feasibility of the proposed method.
