The invention comprises a rapid patient positioning system including a computer and motor controlled patient constraint system, such as a patient head and/or back support system having multiple adjustable degrees of freedom that facilitates accurate, precise, and rapid alignment of a patient relative to a support or table. The patient support system is preferably integrated with a rapid patient positioning system including steps of: positioning a patient relative to the table in a substantially vertical orientation, transitioning the table through a semi-vertical orientation, such as with a robot arm, and orientating the patient and the table in a substantially horizontal orientation, such as in a position for charged particle tumor therapy. Preferably, the robot arm is in common with an arm used to move the patient in traditional proton therapy.

1. An apparatus for treatment of a tumor of a patient using positively charged particles, comprising: a body support surface, comprising a longitudinal axis;a torso support comprising a left pad slideably attached to said body support surface and a right pad slideably attached to said body support surface, said torso support configured to constrain movement of a left shoulder of the patient with said left pad and a right shoulder of the patient with said right pad relative to said body support surface, said torso support comprising: an adjustable shoulder distance between said left pad and said right pad, at least one motor configured to axially translate at least one of said right pad and said left pad relative to the longitudinal axis of said body support surface;andan accelerator configured to deliver the positively charged particles to the tumor when said body support surface supports the patient. 2. The apparatus of claim 1, further comprising: a computer system configured to recall a stored shoulder width ergonomic parameter of the patient, said computer system used to control said at least one motor to set said adjustable shoulder distance for the patient using the shoulder width ergonomic parameter. 3. The apparatus of claim 2, further comprising: an adjustable back distance between said support surface and, during use, a portion of at said torso support proximate a back of the patient. 4. The apparatus of claim 3, said computer system configured to recall a stored back shape ergonomic parameter of the patient, said computer system used to control a second motor to set the adjustable back distance between said support surface and the back of the patient using the back shape ergonomic parameter. 5. The apparatus of claim 2, further comprising: means for co-moving the body support surface and the patient from an angle less than thirty degrees off of a vertical axis to less than thirty degrees off of a horizontal axis. 6. The apparatus of claim 1, further comprising: a robot arm configured to re-orientate the body support surface from a first orientation within twenty degrees of vertical and a second orientation within twenty degrees of horizontal while the patient is supported by said body support surface. 7. The apparatus of claim 6, further comprising: a foot support attached to said body support surface, wherein during use the patient stands on said foot support in said first orientation. 8. The apparatus of claim 6, further comprising: a motorized head support adjustably attached to said body support surface, said computer system configured to adjust position of said motorized head support relative to said body support surface. 9. The apparatus of claim 6, wherein said accelerator further comprises: at least sixteen turning magnets about a circulation beam path, wherein each of said turning magnets comprise at least one beveled surface configured to focus a charged particle beam during use. 10. A method for treatment of a tumor of a patient using positively charged particles, comprising the steps of: supporting the patient on a body support surface comprising a longitudinal axis;constraining motion of both a left shoulder and a right shoulder of the patient relative to the body support surface using a torso support comprising a left pad slideably attached to said body support surface and a right pad slideably attached to said body support surface, said torso support comprising: an adjustable shoulder distance between said left pad and said right pad; using at least a first motor to axially translate at least one of said right pad and said left pad relative to the longitudinal axis of said body support surface;andtreating the tumor using positively charged particles delivered from an accelerator while said body support surface supports the patient. 11. The method of claim 10, further comprising the steps of: using a computer system to recall a stored shoulder width ergonomic parameter of the patient; andusing said computer system to control said first motor to set said adjustable shoulder distance for the patient using the shoulder width ergonomic parameter. 12. The method of claim 11, further comprising the step of: adjusting a distance between said support surface and a back of the patient using a second motor controlled by said computer system to move said torso support. 13. The method of claim 11, further comprising the step of: simultaneously moving the body support surface and the patient from an angle less than thirty degrees off of a vertical axis to less than thirty degrees off of a horizontal axis. 14. The method of claim 10, further comprising the step of: using a robot arm to re-orientate the body support surface from a first orientation within twenty degrees of vertical to a second orientation within twenty degrees of horizontal while the patient is supported by said body support surface. 15. The method of claim 14, further comprising the step of: circumferentially rotating the longitudinal axis of the support surface at least one hundred eighty degrees around the vertical axis using said robot arm. 16. The method of claim 14, further comprising the step of: using a foot support attached to said body support surface to support the patient standing in said first orientation. 17. The method of claim 16, further comprising the step of: using the computer system to set a head constraint position relative to said body support surface. 18. The method of claim 11, further comprising the steps of: controlling both intensity and energy of the charged particles, wherein for a given axis of treatment of the tumor the intensity and energy comprise a correlation coefficient of at least six-tenths for at least three energy levels of the charged particles. 19. The method of claim 10, further comprising the step of: generating a tomographic image of at least a portion of the patient using the positively charged particles.
