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

  • defining a set of one or more optimization goals, the set of one or more optimization goals comprising a desired dose distribution in the subject;

    specifying an initial plurality of control points along an initial trajectory which involves relative movement between a radiation source and the subject;

    iteratively optimizing a simulated dose distribution relative to the set of one or more optimization goals to determine one or more radiation delivery parameters associated with each of the initial plurality of control points; and

    upon reaching one or more initial termination conditions;

    adding one or more additional control points to obtain an increased plurality of control points;

    iteratively optimizing the simulated dose distribution relative to the set of optimization goals to determine one or more radiation delivery parameters associated with each of the increased plurality of control points.
