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

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 ...

Optical microscopy for imaging through scattering media

Xin Yang

Optical microscopy has been widely used in the life sciences and biological research for several decades. It possesses many advantages over x-ray radiography, computed tomography, ultrasound imaging and magnetic resonance imaging, in terms of being low cos ...

Visualization of water drying in porous materials by X-ray phase contrast imaging

Anne Bonnin

We present in this study results from X-ray tomographic microscopy with synchrotron radiation performed both in attenuation and phase contrast modes on a limestone sample during two stages of water drying. No contrast agent was used in order to increase th ...

Multiphase-Field Modeling of Micropore Formation in Metallic Alloys

Michel Rappaz, Alain Jacot, Hossein Meidani

A 3D phase-field (PhF) model has been developed to study the formation of micropores constrained to grow within a well-developed solid network. The model accounts for the equilibrium condition at triple (solid-liquid-pore) lines and the partitioning of dis ...

Characterization of structural disturbances in peats by X-ray CT-based density determinations

Alexandre Buttler, Pascal Turberg, Fränz Zeimetz

Bulk densitywas determined indirectly in peat samples by X-ray computed tomography (X-ray CT) and compared with density values obtained by standard laboratory methods. Five Histosols were collected in the same cut-over peatland, representing various degree ...

A sensitive x-ray phase contrast technique for rapid imaging using a single phase grid analyzer

Peter Modregger, Simon Rutishauser, Christian David, Marco Stampanoni

Phase contrast x-ray imaging (PCXI) is a promising imaging modality, capable of sensitively differentiating soft tissue structures at high spatial resolution. However, high sensitivity often comes at the cost of a long exposure time or multiple exposures p ...

Feasibility of direct mapping of cerebral fluorodeoxy-D-glucose metabolism in situ at subcellular resolution using soft X-ray fluorescence

Rolf Gruetter, Carole Poitry-Yamate, Mario Gaetano Lepore, Vincent Gajdosik

Glucose metabolism is difficult to image with cellular resolution in mammalian brain tissue, particularly with (18) fluorodeoxy-D-glucose (FDG) positron emission tomography (PET). To this end, we explored the potential of synchrotron-based low-energy X-ray ...

Direct mapping of 19F in 19FDG-6P in brain tissue at subcellular resolution using soft X-ray fluorescence

Rolf Gruetter, Carole Poitry-Yamate

Low energy x-ray fluorescence (LEXRF) detection was optimized for imaging cerebral glucose metabolism by mapping the fluorine LEXRF signal of 19 F in 19 FDG, trapped as intracellular 19 F-deoxyglucose-6-phosphate ( 19 FDG-6P) at 1μm spatial resolution from ...
