1. A system for treating a patient during radiation therapy, the system comprising:
multiple range compensators; and
a single positioning component coupled to the multiple range compensators, wherein each range compensator of the multiple range compensators respectively shapes a distribution of a dose delivered to the patient by a respective beam of a plurality of beams emitted from a nozzle of a radiation treatment system along different paths between the nozzle and a target in the patient, and wherein the multiple range compensators are located on the single positioning component to hold the multiple range compensators in place on the patient at respective locations corresponding to the different paths.
