In the calculation of the Pore Size Distribution (Granulometry), the algorithm used to determine the size of a pore is purely geometrical. A pore radius is determined by fitting spheres into the pore volume. To be more precise, a point belongs to a pore of radius , if it is inside a sphere of radius , which can be fitted into the pore space.
