  • PARTICLE THERAPY SYSTEM, PARTICLE THERAPY METHOD, AND RECORDING MEDIUM
    Publication number: 20220323790
    Abstract: A particle therapy system includes: an accelerator that accelerates a particle beam; an irradiation system that applies the beam accelerated by the accelerator to a target; and a controller that controls the accelerator and the irradiation system. The controller has a treatment execution system that generates a control parameter which controls the accelerator and the irradiation system based on a treatment plan and has a treatment execution controller that controls the accelerator and the irradiation system based on the control parameter generated by the treatment execution system. When irradiation to the target by the irradiation system is suspended due to a failure or an artificial manipulation, the treatment execution system calculates an irradiated dose of the particle beam and an unirradiated dose of the particle beam, and the treatment execution system delivers at least the unirradiated dose to the treatment execution controller.

  • Particle beam treatment system
    Patent number: 10293183
    Abstract: An object of the present invention is to provide a particle beam treatment system that can realize the reduction of treatment time for a specific patient, compared with treatment time in a conventional type. A control unit of a control system controls a beam routing system and irradiation devices so as to maintain the occupation of an accelerator when a certain treatment room of plural treatment rooms once occupies the accelerator except intentional operation to release the occupation of the accelerator or the occurrence of system failure.
