Patent ID: 8489366

Claim:
A computer program product for selecting a desired portion of a subject to receive a radiation dose, the computer program product comprising a computer usable tangible non-transitory medium having a computer readable program code thereon, the computer readable program comprising program codes for: a) selecting a plurality of points on a Pareto surface (PS) using a plurality of weight factors, wherein weight factors corresponding to an objective function of the PS that is being minimized are set to a first value while weight factors corresponding to all other objective functions of the PS are set to a second value; b) iteratively choosing additional weight factors to run to build up a model of the PS; c) examining each point that has been found on the PS along with the weight factor used to produce the point to determine if the point is indicated a Pareto optimal; d) identifying new weight factors including a weight factor chosen to be such a convex combination of weight factors of vertices of the PS that is different from the weight factors of said vertices; and e) repeating steps a) through d) using the new weight factors until a Pareto optimal stop tolerance is met.
