Abstract
A device for aligning a patient for delivering a plurality of radiation beams comprising a patient support surface, a coarse alignment subsystem connected to the patient support surface, and a fine alignment subsystem connected to the patient support surface. 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.
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.
Claims (20)
1. ~A system for positioning a patient for delivery of a plurality of radiation beams, the system comprising:
a patient support surface;
a first subsystem configured to induce course movements of the patient support surface;
a second subsystem configured to induce fine movements of the patient support surface; and a control device configured to receive data indicative of flexion behavior of a 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.
a patient support surface;
a first subsystem configured to induce course movements of the patient support surface;
a second subsystem configured to induce fine movements of the patient support surface; and a control device configured to receive data indicative of flexion behavior of a 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.
2. ~The system of claim 1, wherein the fine movements comprise submillimeter translations.
3. ~The system of claim 2, wherein the fine movements comprise subdegree rotations.
4. ~The system of claim 1, wherein the fine movements comprise translations in three perpendicular axes.
5. ~The system of claim 1, wherein the course movements comprise translation motions of as large as approximately two meters.
6. ~The system of claim 5, wherein the course movements comprise rotations of as large as approximately sixty degrees.
7. ~The system of claim 1 further comprising a position detection subsystem configured to calculate the position of the patient support surface.
8. ~The system of claim 1, wherein the second subsystem further comprises a linear actuator coupled to the patient support surface.
9. ~The system of claim 8, wherein the linear actuator is configured to induce roll movement of the patient support surface.
10. ~The system of claim 1, wherein the received data comprises information indicative of flexion behavior during movement of the radiation beam delivery device from a first device position to a second device position.
11. ~A method for positioning a patient for delivery of a plurality of radiation beams, the method comprising:
aligning a target tissue of a patient at approximately a beamline center of a radiation beam delivery device oriented at a first position;
delivering a first radiation beam from the first position;
moving the radiation 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 device, wherein said act of compensating comprises aligning the target tissue 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.
aligning a target tissue of a patient at approximately a beamline center of a radiation beam delivery device oriented at a first position;
delivering a first radiation beam from the first position;
moving the radiation 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 device, wherein said act of compensating comprises aligning the target tissue 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.
12. ~The method of claim 11, wherein said acts of aligning and compensating comprise movement of a patient support surface.
13. ~The method of claim 12, wherein said act of compensating is performed by a fine alignment subsystem.
14. ~The method of claim 13, wherein the fine alignment subsystem is electronically controlled.
15. ~The method of claim 14, wherein said act of compensating comprises submillimeter translation of the patient support surface.
16.~The method of claim 15, wherein said act of compensating comprises translation of the patient support surface in three perpendicular axes.
17. ~The method of claim 15, wherein said act of compensating comprises subdegree rotations of the patient support surface.
18. ~A method for aligning a patient during treatment with a plurality of radiation beams, the method comprising:
receiving predetermined data indicative of flexion behavior of a radiation beam delivery device configured to move between a plurality of beam delivery positions;
aligning a patient support device 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 delivery position, wherein said act of compensating comprises using at least a portion of the predetermined data to align said patient support device.
receiving predetermined data indicative of flexion behavior of a radiation beam delivery device configured to move between a plurality of beam delivery positions;
aligning a patient support device 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 delivery position, wherein said act of compensating comprises using at least a portion of the predetermined data to align said patient support device.
19. ~The method for claim 18, wherein said act of compensating is such that a target tissue of a patient positioned on the patient support device is approximately at a beamline center of the radiation beam delivery device oriented in the second delivery position.
20.~The method of claim 18, additionally comprising compensating for flexion behavior of the radiation beam delivery device produced by movement of the radiation beam delivery device to a third delivery position.
