Validation of radiographic simulation codes including x-ray phase effects for millimeter-size objects with micrometer structures

Abstract

The mix between x-ray phase and attenuation information needs to be understood for accurate object recovery from radiography and tomography data. We are researching and experimentally validating algorithms that simulate x-ray phase contrast to determine the required physics necessary for quantitative object recovery. The results of a study are described to determine if a multislice (beam-propagation) method is required for simulating x-ray radiographs. We conclude that the multislice method is not required for accurate simulation of greater than or equal to $8\mathrm{keV}$ x-ray radiographs of millimeter-size objects with micrometer structures.
