Abstract
Methods for planning delivery of radiation dose to a target region within a subject comprise: initializing a first plurality of control points located on a trajectory, the trajectory comprising relative movement between a radiation source and the subject, wherein initializing the first plurality of control points comprises assigning, to each the first plurality of control points, one or more axis positions which specify a position of the radiation source relative to the subject; specifying 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 a stimulated dose distribution over the second plurality of control points to thereby determine a radiation delivery plan by assigning each of the second plurality of control points optimized values for one or more radiation delivery parameters.
