An algorithm to compute the three-dimensional medial axis transform of digitized media is introduced. The medial axis serves as a tool to analyze the geometric structure of void space in porous media. The technique is used to study high resolution (5 micron), three dimensional, synchrotron computed microtomographic data consisting of two drill core samples (Berea sandstone and Danish chalk) and a sample of uniform diameter, packed glass beads. Recent work developing the medial axis representation of the pore space will be shown. From analysis of the medial axis, results are obtained for the burn number distribution, distribution of disconnected void volumes, and tortuosity distributions between parallel faces. The burn number and disconnected void volume distributions exhibit power-law behavior. The tortuosities in contrast are distributed as generalized gamma distributions.
