X-ray microtomography is a non-destructive 3D imaging technique. The 3D images of the interior of an object are obtained by collecting a series of 2D images at various different angles.

The grey levels of each projection are linked up to the absorption coefficient and to the thickness of the object in relation to its angular position.

A reconstruction algorithm enables the recalculation, using the combination of all 2D projections that have been collected, of the absorption coefficient of the object at each point of the volume of the object.

Novitom is therefore able to generate a quantitative 3D representation of the variations of density that can be found within the object.
