Abstract

A particle therapy system is provided. The particle therapy system includes an imaging unit and a rotatable gantry with an irradiation unit. The irradiation unit projects into an irradiation room delimited by a wall. The imaging unit is arranged on a C-arm. The C-arm is operable to be moved between a retracted parking position und an extended diagnostic position for imaging purposes.

Claims

1. A particle therapy system comprising:

a rotatable gantry with an irradiation unit, which projects into an irradiation room delimited by a wall, and

an imaging unit on a C-arm,

wherein the C-arm is operable to be moved between a retracted parking position and an extended diagnostic position for imaging purposes.

2. The particle therapy system as claimed in claim 1, wherein the C-arm is mounted on the wall of the irradiation room, such that C-arm is operable to rotate along with a rotation of the gantry.

3. The particle therapy system as claimed in claim 1, wherein the C-arm, in its retracted position, lies against a rear wall of the irradiation room.

4. The particle therapy system as claimed in claim 2, wherein the rear wall includes a recess for the C-arm.

5. The particle therapy system as claimed in claim 4, wherein the recess is circular.

6. The particle therapy system as claimed in claim 3, wherein the rear wall includes a holding device for the C-arm, the holding device being operable to be moved relative to the rear wall.

7. The particle therapy system as claimed in claim 6, wherein the C-arm is mounted on the holding device such that the C-arm is operable to be rotated by at least 180°

around its midpoint.

8. The particle therapy system as claimed in claim 1, wherein the C-arm is fixed in a pivotable manner and in its extended position is arranged inclined to the vertical.

9. The particle therapy system as claimed in claim 1, wherein the C-arm and the irradiation unit are arranged opposite to each other.

10. The particle therapy system as claimed in claim 7, wherein the C-arm is mounted on the holding device in such a way that the C-arm is operable to be rotated by 200°

around its mid point.

11. The particle therapy system as claimed in claim 2, wherein the C-arm, in its retracted position, lies against a rear wall of the irradiation room.

12. The particle therapy system as claimed in claim 11, wherein the rear wall includes a recess for the C-arm.

13. The particle therapy system as claimed in claim 12, wherein the recess is circular.

14. The particle therapy system as claimed in claim 13, wherein the rear wall includes a holding device for the C-arm, the holding device being operable to be moved relative to the rear wall.

15. The particle therapy system as claimed in claim 14, wherein the C-arm is mounted on the holding device such that the C-arm is operable to be rotated by at least 180°

around its midpoint.
