<p>A device (10) for aligning a patient for delivering a plurality of radiation beams comprising a patient support surface (12), a coarse alignment subsystem (14) connected to the patient support surface, and a fine alignment subsystem connected to the patient support surface (16). A method of aligning a patient for delivering a plurality of radiation beams from a plurality of device positions comprising compensating for flexion of a radiation beam delivery device within a gantry during movement of the radiation beam delivery device from a first device position to a second device position by using a set of predetermined data describing the flexion behavior of the radiation beam delivery device so that the target tissue within the patient is placed at the beamline center for the radiation beam delivery device at the second device position.</p> |
