A method for obtaining the profile area and volume of any specified section of any specified corpuscle is disclosed. The operator operates a personal computer running a program which includes a general representation of the corpuscle to be sectioned. The operator specifies two coordinate rotation angles and two section positions, as well as additional attributes of the corpuscle representation, in response to prompts on a video screen, using a keyboard. The program superimposes a unit cubic lattice on the corpuscle representation. Two coordinate rotations are performed defining a new X'-Y' plane, and two sectioning planes are drawn parallel to a new X'-Y' plane. The new X'-Y' plane is subdivided into unit squares. The program then examines each lattice point in turn. The volume of the corpuscle section is obtained by counting the total number of those lattice points which lie in the interior of the corpuscle between the sectioning planes; the profile area of the corpuscle section is obtained by counting the total number of unit squares which contain the orthogonal projection of at least one of those lattice points.
