X-ray imaging with phase-contrast increases the sensitivity to density-variations, especially suitable for boosting the contrast of air/tissue interfaces in respiratory imaging. This has been successfully demonstrated on animal models (mice, rats, rabbits, and pigs) but the technological translation for human imaging is still far ahead. In our work we explore the potential clinical impact of phase-contrast chest radiography through a virtual study using XCAT phantoms and state-of-the-art simulations. We find that the proposed technique increases the visibility of small airways and pulmonary nodules presenting low absorption-contrast.
