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.

A method for determining a water equivalent depth between an entrance point and a reference point is disclosed. The method may comprise sending to a charged particle beam detector placed at a reference point within or beyond a body a charged particle beam whose energy is modulated between a minimum and maximum energy value, acquiring the time dependent response of said charged particle beam detector, determining from said time dependent response a value of a statistical parameter, providing a calibration curve expressing a relationship between values of said statistical parameter and water equivalent depths, and extracting from this calibration curve the water equivalent depth corresponding to the value of the statistical parameter determined from the time dependent response of the charged particle beam detector placed at the reference point.

The present invention relates to a pulsed beam particle accelerator which can be used for particle radiation therapy. More particular, a device and method are provided to control the number of particles within a beam pulse. The particle accelerator comprises means for varying the number of particles within each beam pulse of said pulsed ion beam from a minimum value to a maximum value as function of the value of a beam control parameter. For each particle irradiation the required number of particles for each beam pulse is controlled by defining a value for said beam control parameter based on calibration data.

The invention relates to a magnet structure for a superconducting isochronous cyclotron for use in particle therapy. The cyclotron according to the invention is using two sets of three or more superconducting sector coil elements for generating an azimuthally varying magnetic field across the acceleration region. In this way, high-field (e.g. above 4 T) isochronous cyclotrons are provided which do not suffer the problem of a low flutter amplitude.

The present disclosure relates to a cyclotron. Embodiments of the present disclosure may include an upper and lower magnet pole, an upper and lower superconducting coil arranged around each of the magnetic poles, a ring-shaped magnetic return yoke, a beam chamber between the upper and lower magnetic poles having one or more electrodes configured to accelerate ions moving substantially in the median plane, and a cryostat. The ring-shaped magnetic return yoke and the coils may form a cold mass contained within the cryostat. Further, the cryostat may not contain the upper and lower poles.
