Claim:
1. A method for planning delivery of radiation dose to a target region within a subject, the method comprising: iteratively optimizing, by a processor, a simulated dose distribution relative to a set of one or more optimization goals comprising a desired dose distribution in the subject over a first plurality of control points located on a trajectory, the trajectory comprising relative movement between a treatment radiation source and the subject; reaching one or more initial termination conditions, and after reaching the one or more initial termination conditions: specifying, by the processor, a second plurality of control points along the trajectory, the second plurality of control points comprising a larger number of control points than the first plurality of control points; and iteratively optimizing, by the processor, a simulated dose distribution relative to the set of one or more optimization goals over the second plurality of control points to thereby determine a radiation delivery plan; the radiation delivery plan capable of causing a radiation delivery apparatus to deliver radiation in accordance with the radiation delivery plan.
