Abstract:
The present invention relates to a particle therapy apparatus used for radiation therapy. More particularly, this invention relates to a gantry for delivering particle beams which comprises means to analyse the incoming beam. Means are integrated into the gantry to limit the momentum spread of the beam and/or the emittance of the beam.

Claim (Index 9):
A particle therapy apparatus comprising:\n a stationary particle beam generator configured to output a particle beam having a first energy; an energy degrader for reducing an energy of the particle beam from the first energy to a second energy, such that an energy spread of the particle beam output by the energy degrader is increased with respect to an energy spread of the particle beam output by the particle beam generator; and a rotatable gantry configured to receive the particle beam having the first or the second energy in a direction substantially along a rotation axis of the rotatable gantry, the rotatable gantry including:\n a beam optic system having a plurality of dipole magnets including a first dipole magnet and a last dipole magnet and configured to bend the received particle beam along a beam path to a target, \n wherein the beam optic system is configured to have a first position along the beam path where a nominal dispersion at the first position is larger than a nominal beam size at the first position, and wherein the first position is located downstream of the first dipole magnet and upstream of the last dipole magnet; and \n an energy spread limiting device, installed at the first position, to limit the energy spread of the particle beam having the second energy to a selected maximum energy spread.
