CHARGED PARTICLE CANCER THERAPY PATIENT POSITIONING METHOD AND APPARATUS
First Claim
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,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.

8. An apparatus for positioning a patient for irradiation of a tumor with charged particles extracted from a synchrotron, comprising:
-
a lower support unit; at least one patient positioning device, said lower support unit supporting said patient positioning device; and means for rotating said lower support unit about an about vertical axis to a plurality of rotation positions, wherein said plurality of rotation positions comprises at least five computer controlled rotation positions in a period of less than two minutes during irradiation of the tumor by the charged particles, said synchrotron configured to deliver the charged particles along an about horizontal axis over a portion of said lower support unit. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
