The invention comprises a charged particle beam, rapid patient positioning system including steps of: positioning a patient relative to a table in a substantially vertical orientation, optionally constraining motion of the patient with one or more constraints, transitioning the table through a semi-vertical orientation, such as with a robot arm, and orientating the patient and table in a substantially horizontal orientation, such as in a position for tumor therapy. Preferably, the robot arm is in common with an arm used to move the patient in traditional proton therapy. Optionally, the robot arm is used to re-orientate the patient into a substantially vertical orientation at the conclusion of a charged particle therapy session.

The apparatus of claim 1, further comprising: a patient movement constraint system configured to constrain lateral movement of the patient relative to a longitudinal axis of the support platform. 5. The apparatus of claim 1, wherein said accelerator comprises a cyclotron. 6. An apparatus for treating a tumor of a patient with charged particles, comprising: a support platform comprising a longitudinal support configured to: (1) position the patient at a first position comprising an angle less than thirty degrees off of a vertical axis at a first period of time; (2) transition the patient through an angle forty-five degrees off of the vertical axis at a second point in time; and (3) orientate the patient at a second position comprising an angle less than thirty degrees off of a horizontal axis at a third period of time; andan accelerator configured to deliver the charged particles to the tumor of the patient when the patient is supported by said longitudinal support of said platform, said accelerator comprising: a synchrotron, said synchrotron comprising:means for using the charged particles to generate a current; andmeans for using the current to control intensity of charged particles extracted from said synchrotron,wherein said means for using the current to control intensity outputs at least: (1) a first number of the charged particles per second, (2) a second number of the charged particles per second at least ten percent less than said first number of charged particles per second, and (3) a third number of the charged particles per second at least ten percent less than said second number of charged particles. 7.

A method for using a charged particle cancer therapy system to treat a tumor of a patient, comprising the steps of: positioning the patient relative to a support, wherein a longitudinal axis of said support comprises a first angle less than thirty degrees off of a vertical axis; andco-transitioning the support and the patient through an angle forty-five degrees off of a vertical axis; andorientating the support and the patient at a second angle less than thirty degrees off of a horizontal axis;after said step of orientating, using charged particles from an accelerator to treat a tumor of the patient; andsimultaneously using an imaging beam running in parallel to the charged particles to image the tumor. 11. The method of claim 10, further comprising the step of: constraining lateral movement of a head of the patient relative to the longitudinal axis of said support. 12. The method of claim 10, further comprising the step of: constraining lateral movement of a torso of the patient relative to the longitudinal axis of said support. 13. The method of claim 10, further comprising the step of: using ions accelerated by said accelerator having at least two protons per atom to generate a tomographic image of the patient. 14. The method of claim 10, further comprising the step of: using a material to slow the charged particles during an extraction of the charged particles after the charged particles have circulated in the accelerator at least twice. 15. The method of claim 10, further comprising the step of: generating a tomographic image of the patient using said accelerator. 16. The method of claim 10, further comprising the steps of: after said step or orientating the support at said second angle and before the patient steps away from the support, performing both: (1) a step of generating a tomographic image of the patient using said accelerator and (2) said step of using the charged particles from said accelerator to treat the tumor of the patient.
