Hydro-mechanical response of Opalinus Clay shale: dependency on composition and burial depth

Shales are sedimentary formation currently studied for their involvement in many geo-energy related applications, such as radioactive waste disposal, CO2 sequestration, oil and gas extraction. In Switzerland the Opalinus Clay shale has been selected has ho ...

Three-dimensional imaging of integrated circuits with macro- to nanoscale zoom

Christian David, Michal Odstrcil, Gabriel Aeppli, Manuel Guizar Sicairos

The imaging of integrated circuits across different length scales is required for failure analysis, design validation and quality control. At present, such inspection is accomplished using a hierarchy of different probes, from optical microscopy on the mil ...

Region Of Interest X-Ray Computed Tomography Via Corrected Back Projection

Michaël Unser, Laura Vilaclara, Michael Thompson McCann

We present a new method for region of interest (ROI) reconstruction from high-resolution, nontruncated data in parallel-ray X-ray computed tomography (CT). Many of the approaches to ROI CT reconstruction in the literature rely on a costly forward projectio ...

Tomographic imaging with harmonic holography in tissues of known refractive index distribution

Demetri Psaltis, Ye Pu

High-resolution imaging in thick biological tissues beyond a few transport mean free path of photons remains a formidable challenge to modern science and technology. Recent advancements in optical tomography have enabled the reconstruction of the three-dim ...

Q&A: Why use synchrotron x-ray tomography for multi-scale connectome mapping?

Giorgio Margaritondo

To understand how information flows and is used in the human brain, we must map neural structures at all levels, providing visualizations similar to those of Google Earth for continents, countries, cities, and streets. Unfortunately, the imaging and proces ...

From closed testaments to books: Virtual X-ray Reading as an alternate digitization technology for fragile documents

Giorgio Margaritondo, Demetri Psaltis, Fauzia Albertin

In recent years, research and technology made considerable progress in increasing the speed and the safety of the entire digitization process of ancient collections. Despite this, imaging ancient, fragile or un-opened documents remains a formidable challen ...

Imaging samples larger than the field of view: the SLS experience

Alessandra Patera, Marco Stampanoni, Goran Lovric

Volumetric datasets with micrometer spatial and sub-second temporal resolutions are nowadays routinely acquired using synchrotron X-ray tomographic microscopy (SRXTM). Although SRXTM technology allows the examination of multiple samples with short scan tim ...
