Systems and methods for global optimization of treatment planning for external beam radiation therapy
First Claim
1. A method of providing an optimal treatment plan in external beam radiation therapy, the method comprising the steps of:
- a. receiving (1) patient image scan data, (2) a prescription radiation dose for a predefined patient target volume, (3) a plurality of beam profile properties, (4) at least one clinical property, and (5) at least one clinical objective;
b. developing a mathematical formulation that optimizes the at least one clinical objective subject to the (1) patient image scan data, (2) the prescription radiation dose for the predefined patient target volume, (3) the plurality of beam profile properties, and (4) the at least one clinical property; and
c. determine a globally optimal solution to the mathematical formulation.

Abstract
Systems and methods for providing an optimal treatment plan for delivering a prescribed radiation dose to a predefined target volume within a patient using an external beam radiation delivery unit are provided. The systems have an interface which is adapted to receive information related to a prescribed radiation dose, a predefined target volume within a patient, and parameters associated with an external beam delivery unit. The systems also have a treatment plan modeling processor which is adapted to receive all of the input data and develop a treatment plan optimization model defining a global system. The systems also have an optimization processor which is adapted to determine an optimal treatment plan based on the treatment plan optimization model and all the input data.
