摘要：
The present invention discloses a system (2, 2') for particle beam therapy, comprising as seen in the flow direction of the particle beam (4): a) an adjustable gantry (10, 10') for the beam delivery to a target volume, said gantry comprising: a1) a beam coupling section (6) for the incoming particle beam (4)； said incoming particle beam (4) being oriented substantially horizontally thereby defining a horizontal plane； a2) a first beam bending section (8, 8') comprising a number of beam deflection and/or focusing magnets (12, 14) wherein the first bending section (8, 8') either bends the particle beam (4) with an adjustable angle into the vertical plane, or with 90 degrees in the horizontal plane, but with the mechanical possibility to rotate with an adjustable angle along the axis of the incoming particle beam (4)； a3) a beam transport section (16) receiving the particle beam (4) leaving the first beam bending section (8, 8') and guiding the particle beam (4) to a second beam bending section (18)； a4) the second beam bending section (18) comprising a number of beam deflection magnets and/or beam focusing magnets； a5) a beam nozzle (20) comprising a window for the exit of the particle beam (4)； and b) a patient table/chair (22) being rotatable in the horizontal plane or in a plane being parallel to the horizontal plane and optionally being adjustable vertically, wherein: c) the gantry (10, 10') is supported by a tilting mechanism(24) allowing the gantry (10, 10') to be tilted vertically by an angle Φ1, Φ1 ԑ [-90°； +90°], wherein the gantry (10, 10') comprises a pivot (7, 7') being disposed in the region of the first bending section (8, 8')； and d) a rotation mechanism (26) beingdisposed in a way that the second beam bending section (18) and the beam nozzle (20) being rotatable by an angle Φ2, Φ2 ԑ [-180°； +180°] around a direction given by the angle Φ1.La présente invention concerne un système (2, 2') pour une thérapie par faisceau de particules, comprend, vu de la d
