Membrane stepping optimization in Modulation Based Imaging
Paola Perion, Clara Magnin, Fulvia Arfelli +3
Modulation-based imaging (MoBI) is an X-ray phase-contrast technique that uses an intensity modulator (or membrane) in the beam. Although MoBI can be performed in a single shot, mu…

On the optimisation of the geometric pattern for structured illumination based X-ray phase contrast and dark field imaging: A simulation study and its experimental validation
Clara Magnin, Laurene Quenot, Dan Mihai Cenda +3
Phase-contrast and dark-field imaging are relatively new X-ray imaging modalities that provide additional information to conventional attenuation-based imaging. However, this new i…

Review of speckle-tracking algorithms for x-ray phase contrast imaging: low dose applications
Rafael Celestre, Laurene Quenot, Christopher Ninham +2
X-ray speckles have been used for a wide variety of experiments, ranging from imaging (and tomography), wavefront sensing, spatial coherence measurements all the way to x-ray photo…
