Abstract

A particle therapy system that includes at least one irradiation chamber, in which an object is irradiated with a treatment beam, an antechamber, which is screened off from radiation occurring in the irradiation chamber and from which access is made to the irradiation chamber, and an access area, which leads to the irradiation chamber and connects the irradiation chamber to the antechamber, is provided. A support for a patient moves along a path of travel from the antechamber, through the access area, to the irradiation chamber. A radiation protection door is arranged in the access area, and the access area is configured geometrically in such a way that the path of travel in the access area is substantially rectilinear.

Claims

1. A particle therapy system, comprising:

an irradiation chamber, in which an object is irradiated with a treatment beam;

an antechamber, which is shielded from radiation occurring in the irradiation chamber; and

an access area to the irradiation chamber, which connects the irradiation chamber to the antechamber so that access from the antechamber to the irradiation chamber is via the access area,

wherein a radiation protection door is arranged in the access area.

2. The particle therapy system as claimed in claim 1, wherein the access area is arranged spatially in relation to the irradiation chamber such that the access area opens out at an acute angle into the irradiation chamber.

3. The particle therapy system as claimed in claim 1, wherein the access area is configured such that a path along which a patient bed is moved from the antechamber to the irradiation chamber is rectilinear.

4. The particle therapy system as claimed in claim 1, further comprising a radiation-protection wall arranged between the irradiation chamber and the access area that protects the radiation protection door from direct radiation, which goes out from an irradiation center in the irradiation chamber.

5. The particle therapy system as claimed in claim 1, wherein a wall projection is arranged in the irradiation chamber such that the wall projection forms a niche in which neutrons generated and emitted during irradiation are captured.

6. The particle therapy system as claimed in claim 1, wherein the radiation protection door attenuates the radiation occurring in the irradiation chamber and penetrating the radiation protection door by at least a factor of 50.

7. The particle therapy system as claimed in claim 1, wherein the radiation protection door has a thickness of at least 50 cm.

8. The particle therapy system as claimed in claim 1, wherein the radiation protection door is a sliding door.

9. The particle therapy system as claimed in claim 1, wherein the access area is separated from the antechamber by an additional door, which is thinner than the radiation protection door.

10. The particle therapy system as claimed in claim 1, wherein the antechamber is configured such that direct access is possible from the antechamber to further rooms, further corridors, or both further rooms and further corridors of the particle therapy system.

11. The particle therapy system as claimed in claim 2, wherein the access area is configured such that a path along which a patient bed is moved from the antechamber to the irradiation chamber is rectilinear.

12. The particle therapy system as claimed in claim 2, further comprising a radiation-protection wall arranged between the irradiation chamber and the access area that protects the radiation protection door from direct radiation, which goes out from an irradiation center in the irradiation chamber.

13. The particle therapy system as claimed in claim 3, further comprising a radiation-protection wall arranged between the irradiation chamber and the access area that protects the radiation protection door from direct radiation, which goes out from an irradiation center in the irradiation chamber.

14. The particle therapy system as claimed in claim 2, further comprising a wall projection arranged in the irradiation chamber such that the wall projection forms a niche in which neutrons generated and emitted during irradiation are captured.

15. The particle therapy system as claimed in claim 4, further comprising a wall projection arranged in the irradiation chamber such that the wall projection forms a niche in which neutrons generated and emitted during irradiation are captured.

16. The particle therapy system as claimed in claim 4, wherein the radiation protection door attenuates the radiation occurring in the irradiation chamber and penetrating the radiation protection door by at least a factor of 50.

17. The particle therapy system as claimed in claim 4, wherein the radiation protection door is a sliding door.

18. The particle therapy system as claimed in claim 6, wherein the radiation protection door is a sliding door.

19. The particle therapy system as claimed in claim 7, wherein the access area is separated from the antechamber by an additional door, which is thinner than the radiation protection door.

20. The particle therapy system as claimed in claim 5, wherein the antechamber is configured such that direct access is possible from the antechamber to further rooms, further corridors, or both further rooms and further corridors of the particle therapy system.
