Method and device for delivering radiotherapy
First Claim
1. A system for delivery of a plurality of radiation beams to a target object, the system comprising:
- a first subsystem configured to induce course movements of a target object with respect to a radiation beam delivery device;
a second subsystem configured to induce fine movements of the target object with respect to the radiation beam delivery device; and
a control device configured to receive data indicative of flexion behavior of the radiation beam delivery device, wherein the control device is further configured to control the second subsystem based at least in part on the received data.

Abstract
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.

11. A method for aligning a target object with a plurality of radiation beams, the method comprising:
-
receiving data indicative of flexion behavior of a radiation beam delivery device configured to move between a plurality of beam delivery positions; aligning the target object prior to the delivery of a first radiation beam from a first delivery position; and compensating for flexion behavior of the radiation beam delivery device produced by movement of the radiation beam delivery device to a second position, wherein said act of compensating comprises using at least a portion of the receives data to align the target object. - View Dependent Claims (12, 13, 14, 15)

16. A method for positioning a target object for delivery of a plurality of radiation beams, the method comprising:
-
aligning a target portion of the target object at approximately a beamline center of a radiation beam delivery device orientated at a first position; delivering a first radiation beam from the first position; moving the ration beam delivery device to a second position; compensating for flexion behavior of the radiation beam delivery device produced by the move to the second position by using a derived set of data indicative of the flexion behavior of the radiation beam delivery device , wherein said act of compensating comprises aligning the target portion at approximately the beamline center of the radiation beam delivery device oriented at the second position; and delivering a second radiation beam from the second position. - View Dependent Claims (17, 18, 19, 20)
