Abstract

In paper, we present a new correction algorithm for the unfunctional cell distortions in conventional CT imaging, based on the Chebyshev orthogonal polynomials series expressions. This algorithm first reevaluates the projection sinograms by the least mean square algorithm, and then the filtered backprojection (FBP) algorithm are executed for the reconstruction of CT image. Through the simulation experiment, the feasibility of this method is validated.
