Definitions

  • the irradiation system 40 includes an irradiation device 13 that shapes the charged particle beam supplied from the transport system 30 into an irradiation field according to the size and depth of the affected area of the patient to be irradiated and irradiates the affected area. .
  • the charged particle beam from the transport system 30 is converged and focused by the quadrupole electromagnets 2 g, 2 h, 2 i, but if used as it is, the beam radius r changes with time t at the irradiation point 10.
  • FIG. 2 shows changes in the beam radius at the irradiation point 10 of the charged particle beam in the particle beam therapy system that controls the beam diameter using only the conventional quadrupole electromagnets 2g, 2h, and 2i.
  • the irradiation point 10 the beam radius of the charged particle beam, those were r 11 at time t 1 changes r 13 at time t3. That is, it can be seen that the beam radius of the charged particle beam varies from r b to the maximum diameter r b + ⁇ r b , and the beam diameter changes with time.
  • the beam diameter of the charged particle beam is reduced by a quadrupole electromagnet 2g, 2h, 2i in accordance with the beam diameter reduction coefficient c smaller than the target beam diameter.
  • the beam radius of the charged particle beam at the irradiation point 10 changes from r 21 at time t 1 to r 23 at time t 3 . That is, the beam radius of the charged particle beam varies from cr b to the maximum radius c (r b + c ⁇ r b ).
  • the initial beam radius, ⁇ ((cr b) 2 + r s 2) r b
  • the distance to the irradiation point 10 can be increased, so that a thinner scatterer can be employed and energy loss can be reduced.
  • FIG. 9 is a schematic diagram showing the configuration of the particle beam therapy system 102 according to Embodiment 3 of the present invention.
  • quadrupole electromagnets 2j, 2k, and 2l and deflection electromagnets 4h and 4i are provided at the downstream end of the transport system 31 to deflect the charged particle beam.
  • the charged particle beam which is deflected by the deflecting electromagnet 4i and simultaneously narrowed to be smaller than the target beam diameter is directly passed through the scanning electromagnets 7a and 7b, and then the scattering amount is adjusted by the scatterer 8.
  • the charged particle beams D1, D2, and D3 are deflected by the deflecting electromagnet 4i, and the diameter of the charged particle beam is narrowed down due to the convergence effect.
  • the charged particle beam exiting the deflection electromagnet 4i is adjusted by adjusting the density of the magnetic flux M in the transverse direction perpendicular to the traveling direction of the charged particle beam. D1, D2, and D3 are converged.
  • the irradiation system 42 does not require a quadrupole electromagnet, and the apparatus can be simplified.
