Phase retrieval and differential phase-contrast imaging with low-brilliance X-ray sources
X-ray radiographic absorption imaging is an invaluable tool in medical diagnostics and materials science. For biological tissue samples, polymers or fibre composites, however, the use of conventional…
X-ray phase imaging with a grating interferometer.
Using a high-efficiency grating interferometer for hard X rays (10-30 keV) and a phase-stepping technique, separate radiographs of the phase and absorption profiles of bulk samples can be obtained…
High-Resolution Scanning X-ray Diffraction Microscopy
A ptychographic imaging method is demonstrated that bridges the gap between CDI and STXM by measuring complete diffraction patterns at each point of a STXM scan.
Probe retrieval in ptychographic coherent diffractive imaging.
Hard-X-ray dark-field imaging using a grating interferometer.
This letter reports a new approach on the basis of a grating interferometer that can efficiently yield dark-field scatter images of high quality, even with conventional X-ray tube sources and is fully compatible with conventional transmission radiography and a recently developed hard-X-ray phase-contrast imaging scheme.
Ptychographic X-ray computed tomography at the nanoscale
An X-ray computed tomography technique that generates quantitative high-contrast three-dimensional electron density maps from phase contrast information without reverting to assumptions of a weak phase object or negligible absorption is described.
Hard-x-ray lensless imaging of extended objects.
A hard-x-ray microscope that does not use a lens and is not limited to a small field of view or an object of finite size is demonstrated, which has revolutionary implications for x-ray imaging of all classes of specimen.
Hard x-ray phase tomography with low-brilliance sources.
This work focuses on how this method can be used for tomographic reconstructions using filtered back projection algorithms to yield quantitative volumetric information of both the real and imaginary part of the samples's refractive index.
Fabrication of diffraction gratings for hard X-ray phase contrast imaging
Tomography with grating interferometers at low-brilliance sources
The coherence requirements for efficient operation of an X-ray grating interferometer are discussed. It is shown how a Talbot-Lau geometry, in which an array of equidistant secondary sources is used,…
