The apparatus of claim 4, said first X-ray imaging system and said second X-ray imaging system combining to form at least one cone beam computed tomography X-ray system. 6. The apparatus of claim 4, said first imaging system further comprising:a first two-dimensional detection surface mounted opposite the rotation point from a center of a connection point of said at least a portion of said first imaging system to said gantry. 7. The apparatus of claim 1, said first imaging system comprising an element of a two-dimensional cone beam computed tomography X-ray system. 8. The apparatus of claim 7, said second imaging system comprising a fluoroscopy system. 9. A method for imaging a tumor of a patient with positively charged particles, comprising the steps of:transporting the positively charged particles, using a beam transport system, from a synchrotron to at least the tumor of the patient along a treatment beam path;functioning a first imaging system along a first imaging beam path from a gantry to the tumor; andoperating a second imaging system along a second imaging beam path from said gantry to the tumor, said first imaging beam path, the tumor, and said second imaging beam path forming an angle of greater than sixty degrees,wherein said gantry physically supports a set of elements comprising: (1) at least a portion of said beam transport system, (2) at least a portion of said first imaging system, and (3) at least a portion of said second imaging system. 10. The method of claim 9, further comprising the step of:rotating said gantry about a rotation point, said step of rotating further comprising the step of:moving said set of elements along a first arc. 11. The method of claim 10, further comprising the steps of:imaging the tumor using both said first imaging system and said second imaging system to form an image; andtreating the tumor with the positively charged particles using the image. 12. The method of claim 11, further comprising the step of:controlling both said step of imaging and said step of treating with a portable control pendant positioned in view of said gantry and outside of a treatment room housing said gantry. 13. The method of claim 11, further comprising the step of:generating a tomographic image from a detected signal resultant from the positively charged particles after the positively charged particles transit through said tumor; andsaid step of treating the tumor further comprising the step of using the tomographic image in targeting the tumor. 14. The method of claim 13, further comprising the steps of:positioning a first light emitting material in a plane across the treatment beam path between an exit nozzle of said beam transport system and the tumor;detecting photons emitted from said light emitting material upon transmission of the positively charged particles through said first light emitting material; anddetermining a path of the positively charged particles using both the photons and said tomographic image. 15. The method of claim 9, said first imaging system further comprising a cone beam computed tomography X-ray based imaging system. 16. The method of claim 15, further comprising the step of:co-rotating: (1) a first source element and a first detector of said first imaging system and (2) a second source element and a second detector of said second imaging system. 17. The method of claim 16, further comprising the step of:tomographically imaging the tumor to form a tomographic image using the positively charged particles. 18. The method of claim 17, further comprising the step of:implementing a cancer treatment therapy plan using both a first image generated using said cone beam computed tomography X-ray based imaging system and said tomographic image. 19. The method of claim 18, further comprising the steps of:said gantry physically supporting a third imaging system, said third imaging system not using X-rays or the positively charged particles; andgenerating a tumor image using said third imaging system. 20. The method of claim 9 further comprising the steps of:rotating the patient with a patient positioning system;generating a cone beam computed tomography image of the tumor without rotation of the gantry; andtreating the tumor of the patient, using the cone beam computed tomography image, with the positively charged particles.
