Phase measurement using x rays (invited)

Abstract

This article reviews the developing field of x-ray phase contrast radiography. The underlying principles are outlined and some experimental results are reviewed. The paper then uses simulations to explore the potential application of this method to the imaging of very low Z elements within a very high Z envelope. We predict that it should be possible to image very light elements such as hydrogen within a gold envelope using small laboratory-based sources. © 2004 American Institute of Physics.
