Application of 3D phase retrieval in a multi-step, masking framework allows for strong phase retrieval to be applied near highly attenuating materials without compromising spatial resolution. Demonstrations in brain computed tomography imaging show up to a 6.8-fold improvement in signal-to-noise ratio over standard phase retrieval processes, further broadening its dose-reduction potential in potential clinical applications.

A deep learning-based algorithm is developed and evaluated that demonstrates the potential to reconstruct simultaneously high-resolution high-frame-rate X-ray image sequences with high fidelity through spatio-temporal fusion. Experimental evaluation shows that the method can significantly improve the accuracy of the reconstruction, achieving an average peak signal-to-noise ratio (PSNR) of more than 35 dB on two representative X-ray image sequences with input data streams of four times lower spatial resolution and 20 times lower frame rate, respectively.

An analyzer-based X-ray phase contrast imaging experiment employing the forward-diffracted o-beam in a thick Bragg-case asymmetrically cut analyzer crystal has been implemented and tested in a geometry very similar to that used in conventional radiography.

The superconducting wiggler beamline IMAGE at the KIT Light Source, dedicated to full-field hard X-ray imaging applications in materials and life sciences, with a focus on high-throughput computed tomography, laminography experiments and systematic in situ and operando studies, is described.

Laboratory powder diffraction and microtomography techniques are sequentially used in the same volume of the same sample to study the process of cement hydration with time.

Experimental and simulated dark-field X-ray microscopy images of isolated dislocations in bulk single-crystal aluminium were combined to identify the Burgers vector, slip plane and line direction of the dislocations. Burgers vector identification missed only the sign, and the line direction was determined with an error of less than 10°, sufficient for most applications.

The CCP-EM Spring Symposium is an annual conference which aims to review and highlight state-of-the-art developments in macromolecular electron cryo-microscopy in an accessible and convivial manner. The conference is held in conjunction with the Diamond Light Source Biological Cryo-Imaging User Meeting for eBIC and B24.

We present HoToPy, a toolbox for X-ray holo-tomography in Python. It offers state-of-the-art phase retrieval methods for synchrotron and laboratory sources as well as tomographic reconstruction and alignment methods.

A biomedical X-ray imaging quality characteristic, suitable for quantitative assessment of X-ray images of biological samples, is introduced and then applied to analysis of propagation-based X-ray phase-contrast computed tomography images of mastectomy samples.

X-rays uncover magnetic phenomena that are driven by interactions between the layers of a kagome ferromagnet. Our understanding of layered quantum materials is still in its early stages. This is highlighted...
