In the aim of producing high-quality discretized 3D images of the porous architecture of C/C composites, computerized microtomographs have been acquired with synchrotron radiation X-rays. Due to the weak X-ray absorption coefficient of carbon, the result of acquisition at 2 or 1 μm resolution are phase contrast images, not usable as such for the evaluation of geometrical or transport properties. We present here an image treatment algorithm designed to overcome this inconvenience.
