Abstract
A respiration phantom that may be used to perform quality assurance on a radiation delivery system. The respiration phantom includes a human-like skeletal structure, at least one deformable component, and a respiration actuator. The deformable component is positionable at least partially internal to the human-like skeletal structure, has a shape resembling an organ of a human anatomy, and attenuates radiation substantially similarly to the organ of the human anatomy. The respiration actuator is positioned to deform the deformable component with a respiration-like motion.
Claims33
A respiration phantom for performing quality assurance on a radiation delivery system, comprising:
- a human-like skeletal structure;
- at least one deformable component positionable at least partially internal to the human-like skeletal structure, the deformable component having a shape resembling an organ of a human anatomy, wherein the deformable component attenuates radiation substantially similarly to the organ of the human anatomy;
- and
- a respiration actuator positioned to deform the deformable component with a respiration-like motion.
A system, comprising:
- a respiration phantom comprising:
- a human-like skeletal structure;
- at least one deformable component positionable at least partially internal to the human-like skeletal structure, the deformable component having a shape resembling an organ of a human anatomy, wherein the deformable component attenuates radiation substantially similarly to the organ of the human anatomy;
- and
- a respiration actuator positioned to deform the deformable component with a respiration-like motion;
- and
- a radiation delivery system including a radiation source and a patient positioning system, the patient positioning system to position the respiration phantom at a preset position and the radiation source moveable to deliver a dose of radiation to the respiration phantom while the respiration actuator is deforming the deformable component with the respiration-like motion.
A respiration phantom for performing quality assurance on a radiation delivery system, comprising:
- means for providing a human-like skeletal structure;
- means for attenuating radiation substantially similar to a organ of a human anatomy, the means for attenuating positioned internal to the means for providing a human-like skeletal structure, the means for attenuating having a shape resembling the organ of a human anatomy and being deformable;
- and
- actuator means for deforming the means for attenuating with a respiration-like motion.
A method of performing quality assurance on a radiation delivery system, comprising:
- cyclically compressing a deformable component internal to a respiration phantom having a human-like skeletal structure along an inferior to superior axis of the respiration phantom, the deformable component having a shape resembling an organ of a human anatomy, wherein the cyclical compression causes the human-like skeletal structure to cyclically expand along a posterior to anterior axis of the respiration phantom;
- and
- emitting a radiation beam from a radiation source of the radiation delivery system at the respiration phantom while cyclically compressing the deformable component.
