Abstract
The invention relates to an ion beam system for irradiating tumor tissues at various irradiation angles in relation to a horizontally arranged patient couch and to a method of carrying out ion irradiations, wherein the patient couch has an apparatus for rotation about a vertical axis and the ion beam system has at least one of the following irradiation systems: a first irradiation system having an asymmetrical scanning system of fixed location, which has a central ion beam deflection region for deflection angles of up to ±15° with respect to the horizontal direction and makes possible scanning of a tumor volume in the central ion beam deflection region, and which has an additional lifting device for the patient couch; a second irradiation system, which has an ion beam deflection apparatus for a deflection angle greater than the first irradiation system and a symmetrical scanning unit for scanning the tumor volume, which scanning unit is arranged downstream of the ion beam deflection apparatus and is arranged to pivot synchronously with the deflection angle of the ion beam deflection apparatus.
