Charged particle beam therapy system having an X-ray imaging device
First Claim
1. Therapy system (100) for irradiating a target volume (2) within a patient (1) with a charged particle beam (6), comprisinga charged particle beam generator (3),a beam transport system (4) for transporting the charged particle beam (6),a nozzle (5) for delivering the charged particle beam (6) to the target volume (2),an X-Ray device (10) comprising an X-Ray source (12) for emitting X-Rays towards the target volume (2), the X-Ray device (10) being movably mounted into the nozzle (5) between a first position wherein the X-Ray device (10) is inside of a treatment path envelope (23) of the charged particle beam (6) within the nozzle (5) and a second position wherein the X-Ray device (10) is outside of said treatment path envelope (23),an X-Ray receiving device (11) mounted opposite to the patient (1) with regard to the X-Ray source (12), and in optical alignment with the X-Ray source (12) when the X-Ray device (10) is in the first position,wherein the therapy system further comprises vacuum means (7) for creating a vacuum within the nozzle (5) so that, in operation, an internal air pressure inside the nozzle is lower than an external air pressure outside the nozzle, and the X-Ray device (10) is rotatably mounted into the nozzle between the first and the second position about a rotation axis (20).

Abstract
Therapy system (100) for irradiating a target volume (2) of a patient (1) with a charged particle beam (6), including a beam generator (3), a beam transport system (4), and a nozzle (5) for distributing the beam to the target volume (2), the nozzle (5) being, when in operation, under vacuum. The therapy system comprises an X-ray device (10) which is rotatably mounted inside the nozzle (5) between a first position and a second position. In the first position, an X-Ray source (12) within the X-Ray device is able to emit X-Rays along a charged particle beam path for generating an X-Ray image on a corresponding X-Ray receiving device (11) arranged opposite to the patient (1), said X-Ray image serving to determine a correct position of the target volume (2) with regard to the charged particle beam (6). In the second position, the X-Ray device (10) is set outside of a charged particle beam treatment path envelope (23), so that the charged particle beam (6) can reach and irradiate the target volume (2).
