title = "Validity of a fully coherent field model for in-line x-ray phase imaging",
abstract = "Accurate models that describe the propagation of partially coherent wave fields and their interaction with refractive index inhomogeneities within a sample are required to optimally design X-ray phase-contrast imaging systems. Several methods have been proposed for the direct propagation of the second-order statistical properties of a wave field. One method, which has been demonstrated for x-ray microscopy, employs a single eikonal for propagation, approximating the phase by an average over the temporal Fourier components of the field. We have revisited this method by use of a coherent mode model from classic coherence theory. Our analysis produces a variant of the transport of intensity equation for partially coherent wave fields.",
