A method for basis decomposition of materials, based on hybrid phase-attenuation X-ray imaging, is presented. The effective composition of the imaged object in terms of two basis materials is reconstructed from X-ray images formed by coherent plane waves. The range of effectiveness of the technique is evaluated by means of a simplified model of image formation and a numerical simulation.
