Patient`s tumor tissue irradiating device, has beam guide formed as symmetrical polygon around isocenter guiding electron beam in supporting structure and on radiation heads, where deflection magnets are arranged for deflecting beam

摘要

The device has an electron source (3) for producing electron beam (8). A set of radiation heads (7) is arranged around an isocenter (2) in a supporting structure (5) and provides radiation in a direction of the isocenter. The electron beam is guided in the supporting structure and on the radiation heads by a beam guide. The beam guide is formed as a symmetrical polygon (10) around the isocenter. Deflection magnets (9) are arranged for deflecting the electron beam. The magnets have a kick device for deflecting the electron beam on the radiation heads.
