摘要： The present invention relates to an ion beam therapy system comprising a plurality of separate patient treatment stations, a source of ions, an accelerator system for accelerating ions as a beam and an ion beam transport system for directing an ion beam from the accelerator to the treatment stations, wherein said ion beam transport system comprises at least a horizontal beam delivery system and at least a gantry (8) rotateable about an axis of rotation, wherein said gantry carries optics for receiving an ion beam on its axis of rotation transporting said ion beam away from the axis of rotation and returning the ion beam on a path intersecting the axis at a target isocentre delivering said ion beam by rotation of the gantry to said target isocentre from different angles between 0 and 360 degrees and wherein said gantry carries means for raster scanning said ion beam enclosing a vertical deflection means and a horizontal deflection means positioned upstream of a last bending magnet downstream the last quadrupole lens of said gentry, wherein said vertical deflection means and said horizontal deflection, so that the beam can be scanned over a predetermined controlled area around said target isocentre after passing said last bending magnet.
