    摘要： The invention comprises a beam adjustment method and apparatus used to perform energy adjustments on circulating charged particles in a synchrotron previously accelerated to a starting energy with a traditional accelerator of the synchrotron. The beam adjustment system uses a radio-frequency modulated potential difference applied along a longitudinal path of the circulating charged particles to accelerate or decelerate the circulating charged particles. Optionally, the beam adjustment system phase shifts the applied radio-frequency field to accelerate or decelerate the circulating charged particles while tightening spatial distribution of a grouped bunch of the circulating charged particles. Optionally, the beam adjustment system simultaneously radially focuses the circulating charged particles using two or more gaps with focusing and/or defocusing edges. The beam adjustment system facilitates treating multiple layers or depths of the tumor without hysteresis and/or between the repeating slow steps of reloading the synchrotron.

    摘要： A rotatable patient positioning apparatus and method of use thereof is described in combination with a rotatable magnet at a termination of a beamline arc. The rotatable patient positioning system optionally: (1) rotates a median of the person in place about a vertical axis and/or (2) rotates the entire person along a path around a vector, such as a vertical axis, where no part of the person intersects the vector. The rotatable targeting magnet rotates independently of a beamline arc at the end of the beamline arc, where the arc is after an accelerator and before the patient in a cancer therapy system. The rotatable targeting magnet directs the charged particle beam, such as vertically, using applied current to the targeting magnet while rotation of the magnet allows scanning across the tumor. The rotatable patient positioning system and targeting magnet combine to target the tumor in three-dimensions.
