  • Particle therapy system
    Patent number: 7586112
    Abstract: 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.
    Type: Grant
    Filed: January 26, 2006
    Date of Patent: September 8, 2009
    Assignee: Hitachi, Ltd.

  • Charged particle therapy apparatus and charged particle therapy system
    Patent number: 7465944
    Abstract: A charged particle therapy system is disclosed in which a hard switch for making a beam request of the accelerator side is installed in an irradiation room so that the accelerator side can start a desired beam irradiation preparation after depressing the hard switch. This arrangement allows the accelerator allocated time to be reduced, thereby improving the usage efficiency of the facilities by increasing the throughput with respect to patients.
