What is X-ray microtomography?

X-ray microtomography is a non-destructive method that allows access to the inner vision of an object (composition, arrangement, defects, porosity); that is to say without cutting the sample. The use of this technique is currently experiencing a boom, particularly in biology.

This imaging technique is based on the property of X-rays to pass through the material and be absorbed in function of the nature and density of the components they cross. A tomographic scan consists in the recording a series of digital radiographs of the sample at various angles. After a "reconstruction" computation, these data allow the 3D visualization, mapping real variation of attenuation of X-rays through the object.

Therefore, the internal structure of the object can be described qualitatively and quantitatively:

  • Dimensional measurements in three dimensions
  • Spatial distribution of the various phases of a heterogeneous material.
  • Characterization of porosity (connectivity, etc)
