First Claim
Patent Images
1. An apparatus for positioning a patient relative to charged particles extracted from a synchrotron for irradiation therapy of a tumor of a patient, comprising:
- a platform configured to support the patient, said platform comprising multi-axis computer control of;
a vertical position of said platform; and
a rotation position of said platform; and
a rotational reamer configured to adjust said rotation position of said platform at a rate in excess of ninety degrees per minute simultaneous with a period of delivery of the charged particles to the tumor,wherein at least a portion of said platform comprises a position under an about horizontal beam path of the charged particles extracted from said synchrotron,said platform configured to rotate, under computer control, to at least ten rotation positions over at least about one hundred eighty degrees of rotation during a tumor treatment period, andwherein said control of position positions the tumor in the about horizontal beam path during use.

Abstract
The invention comprises a patient positioning method and apparatus used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. The patient positioning system is used to translate the patient and/or rotate the patient into a zone where the proton beam can scan the tumor using a targeting system. The patient positioning system is optionally used in conjunction with systems used to constrain movement of the patient, such as semi-vertical, sitting, or laying positioning systems.

7. A method for positioning a patient relative to charged particles extracted from a synchrotron for irradiation therapy of a tumor of a patient, comprising the steps of:
-
supporting the patient on a platform; computer controlling a vertical position of said platform; computer controlling a rotation position of said platform, wherein at least a portion of said platform comprises a position under an about horizontal beam path of the charged particles extracted from said synchrotron; rotating said platform, under computer control, to at least ten rotation positions over at least about one hundred eighty degrees of rotation during a tumor treatment period; simultaneously varying at least one of energy and intensity of the charged particles during said step of rotating; and positioning the tumor of the patient with said platform in the about horizontal beam path during use. - View Dependent Claims (8, 9, 10, 11, 12, 14, 15, 16, 17)

13. A method for positioning a patient relative to charged particles extracted from a synchrotron for irradiation therapy of a tumor of a patient, comprising the steps of:
-
supporting the patient on a platform; computer controlling a vertical position of said platform; computer controlling a rotation position of said platform, wherein at least a portion of said platform comprises a position under an about horizontal beam path of the charged particles extracted from said synchrotron; rotating said platform, under computer control, to at least ten rotation positions over at least about one hundred eighty degrees of rotation during a tumor treatment period; and positioning the tumor of the patient with said platform in the about horizontal beam path during use; controlling energy of the charged particles; controlling intensity of the charged particles; and delivering the charged particles at a repeating period, said period correlated to a rhythmic pattern of the patient'"'"'s respiration cycle.
