Charged particle cancer therapy patient positioning method and apparatus
First Claim
1. An apparatus for positioning a tumor of a patient for treatment with positively charged particles, comprising:
- a charged particle irradiation system comprising a charged particle beam path;
a patient positioning system configured to place the patient in said charged particle beam path;
an emission foil positioned in said charged particle beam path; and
a coating on said emission foil, said coating comprising a layer yielding a localized photometric signal when struck by the positively charged particles, said localized photometric signal used to verify both a horizontal position of the positively charged particles and a vertical position of the positively charged particles in said charged particle beam path relative to the patient positioning system.

Abstract
The invention comprises a patient positioning and/or repositioning system, such as a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle radiation therapy. Patient positioning constraints optionally include one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are preferably movable and/or under computer control for rapid positioning, repositioning, and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the charged particle beam path to accurately and precisely target the tumor, and/or in system verification and validation.

16. A method for positioning a tumor of a patient for treatment with positively charged particles, comprising:
-
positioning the patient relative to a charged particle beam path with a patient positioning system; transmitting the positively charged particles through a foil, said foil comprising a layer yielding a localized photometric signal when struck by the positively charged particles; verifying both a horizontal position of the positively charged particles and a vertical position of the positively charged particles relative to the patient positioning system using the localized photometric signal. - View Dependent Claims (17, 18, 19, 20, 21)
