Patent ID: 8766218

Claim:
An isocentric gantry designed for rotating around an axis of rotation and for delivering a particle beam for use in particle therapy comprising: a gantry beam line having a gantry entrance point ( 25 ) for entering said particle beam into the gantry in a direction essentially parallel with the axis of rotation; a first ( 20 ), a second ( 21 ) and a third ( 22 ) dipole magnet sequentially arranged for successively bending the particle beam in a single plane and for delivering said particle beam at an isocenter ( 27 ) in a direction essentially perpendicular to the axis of rotation; quadrupole magnets ( 24 ) for focusing and defocusing said particle beam; and a particle beam scanning means ( 23 ) installed between said second dipole magnet ( 21 ) and said third dipole magnet ( 22 ) and configured for scanning said particle beam in both X and Y directions over a target area at the isocenter ( 27 ) wherein said third dipole magnet ( 22 ) has a bending angle smaller than 80°.
