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.

10. 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. - View Dependent Claims (11, 12, 13)
