Fast iterative reconstruction of differential phase contrast X-ray tomograms

Michaël Unser, Cédric René Jean Vonesch, Masih Nilchian, Peter Modregger

Differential phase-contrast is a recent technique in the context of X-ray imaging. In order to reduce the specimen's exposure time, we propose a new iterative algorithm that can achieve the same quality as FBP-type methods, while using substantially fewer ...

X-ray imaging of tumor growth in live mice by detecting gold-nanoparticle-loaded cells

Giorgio Margaritondo

We show that sufficient concentrations of gold nanoparticles produced by an original synthesis method in EMT-6 and CT-26 cancer cells make it possible to detect the presence, necrosis and proliferation of such cells after inoculation in live mice. We first ...

Size control of gold nanoparticles by intense X-ray irradiation: the relevant parameters and imaging applications

Giorgio Margaritondo

We report the analysis of a reducing-agent-free synthetic method based on intense X-ray irradiation in the presence of 11-mercaptoundecanoic acid (MUA) and their application in biomedical imaging. The method is very effective in controlling the size and si ...

A perspective on novel sources of ultrashort electron and X-ray pulses

Cécile Hébert, Fabrizio Carbone

Recently, much attention has been devoted to the development of new pulsed sources of radiation for investigating matter with atomic scale temporal and spatial resolution. While much has been achieved thanks to modern ultrafast laser technology, the ultima ...

Power efficient asynchronous multiplexer for X-ray sensors in medical imaging analog front-end electronics

Pierre-André Farine, Rafal Tomasz Dlugosz

This paper presents a new power efficient asynchronous multiplexer(MUX) for application in analog front-endelectronics(AFE) used in X-ray medical imaging systems. Contrary to typica lsynchronous MUXes that have to be controlled by a clock, this circuit fea ...

X-ray Imaging and Analysis of 3D Microstructural Changes in Aged Ni-YSZ Anode

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes

Ni-YSZ anode supports were used to fabricate test cells composed of yttria-stabilised zirconia (YSZ) electrolyte and lanthanum strontium ferrite (LSF) or lanthanum strontium manganite (LSM) / YSZ cathodes. These cells were operated at 720 °C at an average ...
