Three-dimensional phase-contrast X-ray microtomography with scanning–imaging X-ray microscope optics

A three-dimensional (3D) X-ray tomographic micro-imaging system has been developed. The optical system is based on a scanning-imaging X-ray microscope (SIXM) optics, which is a hybrid system consisting of a scanning microscope optics with a one-dimensional (1D) focusing (line-focusing) device and an imaging microscope optics with a 1D objective. In the SIXM system, each 1D dataset of a two-dime...

Metallic foams characterization using X-ray microtomography

Abstact Due to their multi properties, metallic foams have become of major interest for both, basic research as well as industrial applications. In order to implement a thin modelling approach of fluid flows in such porous media, a three dimensional investigation of their internal structure is fundamental. An open-cell nickel foam is imaged using X-ray microtomography. The morphology of the foa...

Three-dimensional full-field X-ray orientation microscopy

A previously introduced mathematical framework for full-field X-ray orientation microscopy is for the first time applied to experimental near-field diffraction data acquired from a polycrystalline sample. Grain by grain tomographic reconstructions using convex optimization and prior knowledge are carried out in a six-dimensional representation of position-orientation space, used for modelling t...

Quantifying Mesoscale Neuroanatomy Using X-Ray Microtomography

Methods for resolving the three-dimensional (3D) microstructure of the brain typically start by thinly slicing and staining the brain, followed by imaging numerous individual sections with visible light photons or electrons. In contrast, X-rays can be used to image thick samples, providing a rapid approach for producing large 3D brain maps without sectioning. Here we demonstrate the use of sync...
