New Methods of X-Ray Imaging based on Phase Contrast

Abstract

Phase-contrast X-ray images can be produced in various ways. Some aspects of the relatively simple “in-line” method are presented which may be implemented using a quasi-spherical X-ray wave with high spatial but not chromatic coherence. Appropriate sources can be found in commercially-available microfocus tubes or at synchrotrons. Compared to previous phase-contrast methods, the present one offers relatively simple implementation, relatively high intensity and a large field of view, making it potentially suitable for clinical applications.
