Abstract

A particle therapy device is provided. The particle therapy device includes a gantry, which is rotatable about an axial axis of rotation and surrounds a treatment chamber with a floor that has at least one movable plate, a treatment table being positionable inside the treatment chamber. To make it possible for a patient, supported on the treatment table, to be irradiated from below as well, the plate is movable horizontally out of the treatment chamber in a transverse direction that extends perpendicular to the axial direction.

Claims

1. A particle therapy device, including:

a gantry that is rotatable about an axis of rotation;

a treatment chamber with a floor having at least one movable plate, the gantry surrounding the treatment chamber; and

a treatment table positionable inside the treatment chamber,

wherein the at least one movable plate is movable horizontally out of the treatment chamber in a transverse direction that extends perpendicular to the axial direction.

2. The particle therapy device as defined by claim 1, comprising receptacles for the at least one movable plate, wherein the receptacle are provided in an axially extending solid wall that laterally defines the treatment chamber.

3. The particle therapy device as defined by claim 1, wherein the at least one movable plate is supported movably on a fixed floor.

4. The particle therapy device as defined by claim 3, wherein on a face end of the fixed floor oriented toward the treatment chamber, a guide element, which extends in the transverse direction, supports and moves the at least one movable plate.

5. The particle therapy device as defined by claim 1, comprising a central base plate and two side plates.

6. The particle therapy device as defined by claim 5, wherein the side plates are pivotably supported.

7. The particle therapy device as defined by claim 6, wherein the side plates are pivotable both upward and downward relative to the floor.

8. The particle therapy device as defined by claim 7, wherein a pivot shaft of the side plates is disposed above the base plate.

9. The particle therapy device as defined by claim 8, wherein the at least one movable plate comprises rollers for support on the guide element.

10. The particle therapy device as defined by claim 1, wherein the floor comprises a plurality of horizontally movable plates.

11. The particle therapy device as defined by claim 4, wherein the guide element, in the region laterally outside the treatment chamber, branches into two split arms extending one above the other.

12. The particle therapy device as defined by claim 4, wherein the at least one plate is bent at an angle in the shape of an L toward the face end of the fixed floor;

and that in the radial direction, a plurality of guide elements are provided.

13. The particle therapy device as defined by claim 4, wherein the guide element is a linear guide, in particular a guide rail or a guide groove.

14. The particle therapy device as defined by claim 1, wherein the at least one movable plate comprises a radiotransparent region.

15. The particle therapy device as defined by claim 1, comprising a robot is operable to position the treatment table.

16. The particle therapy device as defined by claim 3, wherein one end of the fixed floor adjoins the treatment chamber.

17. The particle therapy device as defined by claim 7, wherein a width of each of the side plates amounts to approximately 15% to 25% of the total width of the floor.

18. The particle therapy device as defined by claim 10, wherein the horizontally movable plates are positionable one above the other laterally outside the treatment chamber.

19. The particle therapy device as defined by claim 15, wherein the robot is secured to the fixed floor.
