1. A method for treatment of a tumor of a patient using positively charged particles moving along a beam path, comprising the steps of: accelerating the positively charged particles using a synchrotron; transporting the positively charged particles along a beam transport path from said synchrotron to an exit nozzle; at a first time, imaging the tumor using a scintillation material positioned posterior to the patient relative to said exit nozzle, said step of imaging using the positively charged particles accelerated in said synchrotron and transported along said beam transport path; and at a second time, treating the tumor using the positively charged particles, the positively charged particles accelerated in said synchrotron and transported along said beam transport path.
