Ion beam system for irradiating tumour tissues

Ion beam system according to one of the preceding claims,

• characterised in that
• the second irradiation system (9) has an ion beam deflection apparatus (14) of fixed location and of variable deflection angle (β) arranged to the side of the patient couch (1);
• and the patient couch (1) has an additional vertical lifting apparatus (8).

Ion beam system according to one of the preceding claims,

• characterised in that
• the first irradiation system (5) has a first deflection magnet (20) for scanning the tumour volume in an X direction of the plane orthogonal to the central ion beam deflection region (7) and has a deflection magnet (21) for deflecting in the direction of the central ion beam deflection region (7) in a Y direction of the plane orthogonal to the central ion beam deflection region (7) with additional superimposition for scanning the tumour volume in that direction.

Ion beam system according to one of the preceding claims,

• characterised in that
• the spacing between the deflection magnet (21) in the Y direction and the patient couch (1) of the first irradiation system (5) is between 5 and 7 metres.

Ion beam system according to one of the preceding claims,

• characterised in that
• the spacing between the displaceable linear track (13) of the solenoid magnet (19) and the patient couch (1) is from 3 to 6 metres and the co-displaceable magnetic scanning unit (11) is arranged in that region.

Ion beam system according to one of the preceding claims,

• characterised in that
• the entire floor of the irradiation room (22, 23, 24) is also raised when the patient couch (1) is raised.

Ion beam system according to one of the preceding claims,

• characterised in that
• the ion beam system (4) has ionisation chamber measurement apparatuses and multiwire chamber measurement apparatuses for measuring the location of, and monitoring, the scanning ion beam (16).

Ion beam system according to one of the preceding claims,

• characterised in that
• the irradiation systems (5, 9) are arranged in irradiation rooms (22, 23, 24) that are located next to one another compactly and in the shape of segments of a circle.

Ion beam system according to one of the preceding claims,

• characterised in that
• the ion beam system (4) has a visual checking means for the patient couch (1) in the irradiation room (22, 23, 24) in order to monitor defined angle-of-rotation changes between various settings for multi-field irradiation of the patient couch (1).

Ion beam system according to one of the preceding claims,

• characterised in that
• the irradiation systems (5, 9) have locking apparatuses for taking up and positioning a patient couch (1) in the irradiation room (22, 23, 24).
