The ability to make precise X-ray attenuation measurements on very small volume elements is a developing technology. This technology is known as X-ray micro-tomography to delineate the method as a form of X-ray microscopy that uses tomographic reconstruction techniques to build three-dimensional images of micro-structure. The morphological data of a microstructure are usually collected from plane cross sections taken through an opaque material. This necessary step results in a great loss of information regarding spatial features of the dispersion. In order to overcome this difficulty X-ray micro-tomography is applied to extract the 3-D information that may be used for micromechanical modelling purposes.
