Abstract
A method for sequencing treatment fields defined by leaves of a multi-leaf collimator positioned to block radiation from a radiation source and define an opening between the radiation source and a treatment area. The multi-leaf collimator is operable to rotate relative to the treatment area to define a plurality of treatment ports. Each of the ports has at least one treatment field. The method includes ordering the collimator ports based on direction of travel of the collimator relative to the treatment area such that each port has at least one corresponding adjacent port. The method further includes selecting a sequence of treatment fields for each collimator port based on the treatment fields within adjacent ports to optimize delivery of radiation.
