(Phys.org) —A new kind of x-ray multilayer grating that could open a pathway for high-sensitivity, hard x-ray phase contrast full-field imaging of large samples has been developed by researchers at the National Institutes of Health, the U.S. Department of Energy Office's (DOE's) Argonne National Laboratory, and Penn State University. In tests at the DOE Office of Science's Advanced Photon Source at Argonne, the device produced phase-contrast images of vascular structures in a mouse kidney specimen that rival those obtained with magnetic resonance imaging. Such soft-tissue structures were previously invisible to conventional attenuation-based x-ray imaging methods.
