Abstract
A particle therapy gantry for delivering a particle beam to a patient includes a beam tube having a curvature defining a particle beam path and a plurality of superconducting, variable field magnets sequentially arranged along the beam tube for guiding the particle beam along the particle path. In a method for delivering a particle beam to a patient through a gantry, a particle beam is guided by a plurality of variable field magnets sequentially arranged along a beam tube of the gantry and the beam is alternately focused and defocused with alternately arranged focusing and defocusing variable field magnets.

A particle therapy gantry for delivering a particle beam to a patient comprising:
- a beam tube dimensioned for use in a patient treatment room to direct a particle beam provided thereto to a patient and having a curvature defining a particle beam path;
- and
- a plurality of variable field magnets sequentially arranged along said beam tube for guiding the particle beam along said particle path.
A method for delivering a particle beam to a patient through a gantry comprising the steps of:
- bending the particle beam with a plurality of variable field magnets sequentially arranged along a beam tube of the gantry, the particle beam traveling in said beam tube and said beam tube being dimensioned for use in a patient treatment room to direct a particle beam provide thereto to a patient;
- adjusting the magnetic field of the variable field magnets based on the energy of the particles in the particle beam;
- alternately focusing and defocusing the particle beam traveling in said beam tube with alternately arranged combined function focusing and defocusing variable field magnets;
- and
- delivering said particle beam from said gantry to a patient, wherein said beam is strongly focused in both the horizontal and vertical planes.
A particle beam therapy system comprising:
- a source of particles;
- an accelerator for accelerating the particles to a desired energy level;
- an injector for transporting the particles from said source to said accelerator;
- a patient treatment room including a rotatable gantry for delivering a beam of the accelerated particles to a patient, said gantry including a beam tube dimensioned for use in the patient treatment room to direct a particle beam provided thereto to a patient and having a curvature defining a particle beam path and a plurality of variable field magnets sequentially arranged along said beam tube for guiding the particle beam along said particle path;
- a beam transport system for transporting the accelerated beam from said accelerator to said patient treatment station;
- and
- a controller for controlling the magnetic field of said variable field magnets based on the energy level of the particles in the accelerated beam.
