Coherence evaluation and first demonstration of multi-contrast X-ray computed tomography on NanoTerasu BL09W with an X-ray Talbot interferometer [PDF]
We report on the coherence evaluation of the beamline BL09W at NanoTerasu (Tohoku University, Japan) and demonstrate X-ray multi-contrast imaging using an X-ray Talbot interferometer.

Moiré artifact reduction in grating interferometry using multiple harmonics and total variation regularization [PDF]
X-ray interferometry is an emerging imaging modality with a wide variety of potential clinical applications, including lung imaging. A grating interferometer uses a diffraction grating to produce a periodic interference pattern and measures how a patient

An electron Talbot interferometer
The Talbot effect, in which a wave imprinted with transverse periodicity reconstructs itself at regular intervals, is a diffraction phenomenon that occurs in many physical systems. Here we present the first observation of the Talbot effect for electron de Broglie waves behind a nanofabricated transmission grating.

The choice of an autocorrelation length in dark-field lung imaging [PDF]
Respiratory diseases are one of the most common causes of death, and their early detection is crucial for prompt treatment. X-ray dark-field radiography (XDFR) is a promising tool to image objects with unresolved micro-structures such as lungs.

Towards virtual histology with X-ray grating interferometry [PDF]
Breast cancer is the most common type of cancer worldwide. Diagnosing breast cancer relies on clinical examination, imaging and biopsy. A core-needle biopsy enables a morphological and biochemical characterization of the cancer and is considered the gold

Spectral X-ray dark-field signal characterization from dual-energy projection phase-stepping data with a Talbot-Lau interferometer [PDF]
Material-selective analysis of spectral X-ray imaging data requires prior knowledge of the energy dependence of the observed signal. Contrary to conventional X-ray imaging, where the material-specific attenuation coefficient is usually precisely known ...

Exploration of the X-ray Dark-Field Signal in Mineral Building Materials [PDF]
Mineral building materials suffer from weathering processes such as salt efflorescence, freeze–thaw cycling, and microbial colonization. All of these processes are linked to water (liquid and vapor) in the pore space. The degree of damage following these

Nanoparticle Interferometer by Throw and Catch [PDF]
Matter wave interferometry with increasingly larger masses could pave the way to understanding the nature of wavefunction collapse, the quantum to classical transition, or even how an object in a spatial superposition interacts with its gravitational ...

Feasibility of a gravity measurement on antimatter using a Talbot-Lau interferometer [PDF]
The past two decades have witnessed an increasing focus on cold antimatter physics, with the development of the Antiproton Decelerator at CERN as a supply of low-energy antiprotons.
