Claim One:
1. An optimization method for radiation therapy planning, comprising the steps of: (a) modeling a tumor mass and a critical mass; (b) positioning a plurality of static particles, each with its own potential function, to a surface of each of the tumor mass and the critical mass; (c) placing a set of kinetic particles, each with its own potential function, to the surface of each of the tumor mass and the critical mass providing a first location of each kinetic particle; (d) applying a momentum to each kinetic particle; (e) computing a static potential field for the plurality of static particles and a dynamic potential field for the set of kinetic particles; (f) calculating a force value incident upon each kinetic particle based on step (e); (g) updating the first location of each kinetic particle to a second location based on the force value creating a second location map; (h) repeating steps (e) through (g) until a variation of distance between the first location map and the second location map converges to less than a given threshold value or until a number of iterations reaches a certain threshold value; (i) recording a location for each kinetic particle; and (j) translating the final location for each kinetic particle to define a plan for execution by one or more radiation sources.
