1. A method for simultaneously generating a plurality of parameters of an object in a field of view, said method comprising the steps of: (a) forming an electrical image of said field of view; (b) processing said electrical image to form a plurality of different representations of said electrical image; wherein each different representation is a Green's function representation of a different parameter of said same field of view; (c) generating positional information that represents the boundary of said object; (d) simultaneously tracing identical corresponding locations in each of said different Green's function representations of said same field of view in response to the positional information generated; and (e) calculating the different parameters from each of said different Green's function representations based upon locations traced in each of said different Green's function representations.
