EPS concretes are composed of high performance cement mixed with millimetre-size expanded polystyrene spheres. They exhibit a priori contradictory thermal and mechanical features that are suitable for the construction industry. This paper aims at cha

Qualitative and quantitative use of volumes reconstructed by computed tomography (CT) can be compromised due to artefacts which corrupt the data. This article illustrates a method based on virtual X-ray imaging to investigate sources of artefacts whi

Porosity formation is greatly influenced in aluminium alloys by the low vaporisation point element (Mg, Zn) content, or by process instability such as key-hole closures that tend to entrap occluded gases during welding. Another important contribution

The first part of the paper describes the principle of the tomography technique. It then shows some setups which can be used to obtain medium (10 μm) and high (1 μm) resolution three dimensional non destructive images. The second part of the paper

La diffusion des rayons X par effets Rayleigh et Compton permet d'obtenir des tomographies de la matiere inerte ou vivante. Nous decrivons un nouveau systeme d'acquisition en tomographie par diffusion et sa methode de reconstruction. Le deplacement d

The detection of X-ray photons scattered through a sample by the Rayleigh and Compton processes is used to perform tomographic images. In the present paper, we describe a new experimental arrangement and the corresponding reconstruction method. The s

Detection and counting X-ray photons scattered by the Rayleigh and Compton processes enable matter to be characterized locally. A theoretical relation was first established which simulates the result of a Rayleigh to Compton ratio measurement. It can

The goal of the present study was to determine if a high-resolution computed tomography (HRCT) system with 150 microns resolution was sufficient to predict mechanical properties in ewe lumbar vertebrae. To answer this question, we used a triangular c
