Abstract
A particle therapy system includes a particle accelerator to output a particle beam; and a scanning system for the particle accelerator to scan the particle beam across at least part of an irradiation target. The scanning system is configured to scan the particle beam in two dimensions that are at an angle relative to a direction of the particle beam. A structure defines an edge. The structure is controllable to move in the two dimensions relative to the irradiation target such that at least part of the structure is between at least part of the particle beam and the irradiation target. The structure includes a material that inhibits transmission of the particle beam.

43. A particle therapy system comprising:
-
a particle accelerator to output a particle beam; one or more scanning magnets that are down-beam of the particle accelerator, the one or more scanning magnets for moving the particle beam relative to at least part of an irradiation target in a patient; an energy degrader that is down-beam of the one or more scanning magnets, the energy degrader comprising a material that allows the particle beam to pass through and thereby reduce an energy of the particle beam, the energy degrader being configurable during movement of the particle beam; and a collimator that is down-beam of the one or more scanning magnets, the collimator being controllable to change a shape of an edge of the collimator, at least a portion of the collimator being movable between a first part of the particle beam and the patient so that the at least a portion of the collimator blocks the first part of the particle beam from reaching the patient and so that the edge at least partly collimates a second part of the particle beam that reaches the irradiation target in the patient.

59. A particle therapy system comprising:
-
a particle accelerator to output a particle beam; an energy degrader to receive the particle beam, the energy degrader comprising a beam-transmissible material that allows the particle beam to pass through the energy degrader and thereby change an energy of the beam; a collimator comprising a material that blocks the particle beam, at least a portion of the collimator being movable into a path of a first part of the particle beam so that the at least a portion of the collimator blocks a first part of the particle beam while allowing a second part of the particle beam to pass; and a control system to control operation of the energy degrader so that at least a portion of the energy degrader moves during movement of the particle beam, and to control operation of the collimator so that the at least a portion of the collimator moves based on the movement of the particle beam. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
