This article introduces a theoretical model for analyzer-based imaging of non-crystalline objects that takes into account the impact of microscopic and macroscopic heterogeneities within the object as well as the instrumental factors. The model includes particular phase variational features required for solving the inverse scattering problem. It provides the possibility to reconstruct the shape of the object from a set of intensity profiles.

Key words: X-ray optic, phase-contrast imaging, dynamical diffraction theory.
