Gantry system useful for particle therapy system for therapy plan and radiation method, particularly for irradiating volume, comprises first and second beam guiding devices guides particle beams

摘要

A gantry system (1) comprises two beam guiding devices (5, 7). The first beam guiding device is rotatable about an axis of rotation of a gantry. The first beam guiding device is operable to guide the particle beam so that the particle beam strikes a treatment location at a gantry incidence direction. The gantry incidence direction deviates from an axis of rotation and is variable. The second beam guiding device is operable to guide the particle beam to a treatment location in a second direction different than the gantry incidence direction. The second direction is parallel to the axis of rotation. The second beam guiding device is non-rotatable and is mechanically optionally uncoupled from the first beam guiding device and is operable to rotate with the first beam guiding device. The system includes beam monitoring unit. The two beam guiding devices have has a scanner, and/or scattering device. The particle therapy system is switchable between =2 of protons, pions, helium ion, carbon ion, and oxygen ion therapy. The second sub-treatment plan defines a radiation based on the radiation parameters of the particle number, particle energy, and/or particle type. The second direction is a direction not obtainable by the first beam guiding device. Independent claims are also included for: (1) particle therapy system (3); (2) operating method for operating a particle therapy system; and (3) treatment plan for irradiating a patient with particles of a particle therapy system.
