    摘要： The invention comprises a method and apparatus for aligning a charged particle beam path for treating a tumor of a patient, comprising: a cancer therapy system comprising the charged particle beam path sequentially passing: from an injector, through a synchrotron, along a beam transport line, and through a nozzle; a first two-dimensional detector configured to measure a beam state of positively charged particles; and an integrated intelligent system configured to classify the beam state into a set of beam shape factors, the integrated intelligent system configured to correct the beam shape through application of a condition-action rule: (1) adjusting a first voltage delivered to a first magnet positioned in the beam line prior to the first two-dimensional detector and (2) altering the beam shape through application of a second voltage to a second magnet position in the beam line adjacent to the first magnet.

    摘要： The invention comprises a method and apparatus for treating a tumor of a patient with positively charged particles, comprising the steps of transporting the positively charged particles along a beam transport path passing sequentially from an accelerator, through a beam transport line, through a nozzle, and toward a position of the patient, the step of transporting further comprising the steps of: (1) terminating a first Bragg peak, of a first set of the positively charged particles, in a position of the tumor and (2) flash treating the tumor with a second Bragg peak, of a second set of the positively charged particles, the second Bragg peak terminating post-patient relative to the nozzle. Optionally the second set of particles are delivered at a rate exceeding one MHz. Optionally, particles in common are used to both treat the tumor and image the tumor.

    摘要： The invention comprises a method and apparatus for tuning a charged particle beam path of a charged particle beam system used to treat a tumor of a patient, comprising the steps of: positioning a two-dimensional charged particle detector in a beam line downstream from a magnet pair; operating windings of the magnet pair at a first power level to generate a first magnetic field; measuring a beam position with the first two-dimensional charged particle detector; adjusting a correction magnetic field by driving voltage of a correction coil at a second power level, the second power level less than five percent of the first power level, where the first magnetic field and the correction magnetic field combine to yield an operational magnetic field; and the steps of measuring and adjusting the correction magnetic field changing the operational magnetic field to adjust a measured beam position toward a target beam position.
