Annotation	In this contribution the issue of the stochastic reconstruction of particulate media from 2D backscatter SEM images is addressed with particular reference to pore space connectivity. The reconstruction of porous bodies in 2D or 3D space was achieved by using a simulated annealing technique. Two constraints were found to be necessary for the successful reconstruction of well connected pore space: the two-point probability function, and the lineal-path function for the solid phase. The effect of the lineal-path function for the void phase on the course of the reconstruction was adjusted by modifying two parameters of the reconstruction procedure. It was tacitly assumed that the parameters adjusted during 2D reconstruction had the same influence on the formation of 3D microstructures.
