Abstract:
A method for the interactive simulation of the movement of a first material in an organism, comprising:(a) constructing a field of local physical quantities appropriate to motion, appearance and disappearance of said material in said organism, and (b) constructing a field of a rate at which fluid flowing in said organism as a consequence of bodily processes or of an injection process moves at each position, thereby transporting said material, and (c) constructing a model of a source from which said material enters said organism, with any pressure differential or flux rate that causes it to enter said organism, and (d) computing a concentration field over time of said material, assuming a planned time course of said pressure differential or flux rate, and (e) using said concentration field to implement control of concentration of said material by adjustment of the source from which said material enters said organism.
