Patent number: 7060997Abstract: A particle therapy system is provided which can simply and quickly correct a beam orbit. In a particle therapy system provided with an irradiation facility comprising a first beam transport system for receiving a beam and transporting the beam to the patient side, and an irradiation nozzle for forming an irradiation field of the beam, the particle therapy system comprises first beam position monitors for detecting a position upstream of the irradiation nozzle at which the beam passes, second beam position monitors for detecting a position downstream of the irradiation nozzle at which the charged-particle beam passes, and first and second steering magnets. Correction bending amounts for causing the beam to be coincident with a predetermined orbit after the correction are determined in accordance with detected results from the first and second beam position monitors, and first and second steering magnets are excited under control so that the determined correction bending amounts are obtained.Type: GrantFiled: July 21, 2005Date of Patent: June 13, 2006Assignee: Hitachi, Ltd.Inventors: Tetsuro Norimine, Masumi Umezawa, Kazuo Hiramoto

Patent number: 6316776Abstract: A method of irradiation with a charged particle beam and an irradiation apparatus wherein the charged particle beam supplied from an accelerator and extracted from the irradiation apparatus. The irradiation apparatus includes an electromagnet for scanning with the charged particle beam. The method includes the steps of stopping the extraction of the charged particle beam from the irradiation apparatus, changing an irradiation point of the charged particle beam by controlling the electromagnet under a condition when the extraction is stopped, and resuming the extraction of the charged particle beam from the irradiation apparatus after changing the irradiation point.Type: GrantFiled: September 2, 1999Date of Patent: November 13, 2001Assignee: Hitachi, Ltd.Inventors: Kazuo Hiramoto, Hiroshi Akiyama, Koji Matsuda, Tetsuro Norimine, Masahiro Tadokoro
