Paper Abstract

We propose a mathematical model for analyzing grid line digitization artifacts on high resolution film. In this paper, aliasing frequencies and the amplitudes of the higher frequency components of grid lines have been derived based on a theoretical model given in an earlier paper. Then the experimental results obtained from digitizing a mammography film are compared with the theoretical results. We propose a method of choosing the optimum digitization parameters in order to minimize grid line aliasing artifacts.
