US Patent 7586112 Particle therapy system

A particle therapy system capable of increasing the number of patients treated in one treatment room per unit time. The particle therapy system comprises a charged particle beam generator for generating an ion beam, an irradiation apparatus for irradiating the ion beam extracted from the charged particle beam generator to an irradiation target, a beam transport system for transporting the ion beam extracted from the charged particle beam generator to the irradiation apparatus, and a central control unit for producing a set of command data to command excitation currents for magnets disposed in the charged particle beam generator and the beam transport system, the set of command data being classified into group-1 data and group-2 data.
