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.

28. A method of aligning a patient with a target tissue within the patient for delivering a plurality of radiation beams from a plurality of device positions comprising:
-
a) providing a radiation beam delivery device having a beamline center;
b) deriving a set of predetermined data describing the flexion behavior of a radiation beam delivery device;
c) selecting a patient having one or more than one target tissue suitable for receiving a plurality of radiation beams;
d) producing a treatment plan;
e) aligning the patient with respect to the radiation beam delivery device oriented at a first device position using the derived set of predetermined data describing the flexion behavior of the radiation beam delivery device to place the target tissue within the patient at the beamline center for the first device position;
f) delivering a first radiation beam from the first device position to the target tissue;
g) moving the radiation beam delivery device to a second device position;
h) compensating for flexion of the radiation beam delivery device produced by the move to the second device position using the derived set of predetermined data describing the flexion behavior of the radiation beam delivery device to place the target tissue within the patient at the beamline center for the second device position; and
i) delivering a second radiation beam from the second device position to the target tissue within the patient. - View Dependent Claims (29, 30, 31, 32, 33, 34)
