1. A method for planning delivery of radiation dose to a target region within a subject, the method comprising:

  • iteratively optimizing a simulated dose distribution relative to a set of one or more optimization goals over a preceding plurality of control points, the preceding plurality of control points located along a preceding trajectory which characterizes relative movement between a radiation source and a subject; and

    upon reaching one or more preceding optimization termination conditions, iteratively optimizing a simulated dose distribution relative to the set of one or more optimization goals over an increased plurality of control points, the increased plurality of control points located along at least one subsequent trajectory which characterizes relative movement between the radiation source and the subject and the increased plurality of control points comprising a larger number of control points than the preceding plurality of control points.
