The invention comprises a method and apparatus for treating a tumor, comprising the steps of: (1) a main controller implementing an initial radiation treatment plan, as a current radiation treatment plan, using positively charged particles delivered from a synchrotron, along a beam transport line, through a nozzle system proximate the treatment room, and into the tumor; (2) concurrent with the step of implementing, imaging the tumor, such as with protons, to generate a current image; (3) upon detection of movement of the tumor relative to surrounding constituents of the patient using the current image, the main controller, using computer implemented code, automatically generating an updated treatment plan, the updated treatment plan becoming the current radiation treatment plan; and (4) repeating the steps of implementing, imaging, and generating an updated treatment plan at least n times, where n is a positive integer of at least one.
