First Claim
Patent Images
1. A method of forming a treatment plan for treating a patient with radiation therapy, the method comprising:
- receiving information corresponding to a tumor position in the patient determined using an imaging device;
selecting a plurality of beam angles for a respective plurality of beams based on the tumor position;
receiving information corresponding to a plurality of constrained and unconstrained objective function parameters related to at least one of a minimum and maximum radiation dosage to a specific region of interest;
selecting an intensity for each beam based, in part, on the objective function parameters;
selecting new unconstrained objective function parameters based, in part, on the previous unconstrained objective function parameters; and
selecting new beam intensities based, in part, on the new unconstrained objective function parameters.

Abstract
This patent generally relates to developing treatment plans for use in external beam radiation therapy, and more particularly to a method, a system and a computer readable media that contains programming for the development of external beam radiation therapy treatment plans. Embodiments of the invention include (1) automatically setting beam angles based on a beam angle automation algorithm, (2) judiciously designing planning structures and (3) automatically adjusting the objectives of the objective function based on a parameter automation algorithm.
