Abstract :
A combination of a Medical Gantry and Patient Positioning System is required to direct a particle therapy beam to a supine patient from a variety of angles. The requirements of beam direction and size for precision beam treatment result in stringent criteria for the magnetics and mechanical structure of the gantry. In this paper the requirements of large gantries for ion therapy will be discussed. A variety of ion beam gantries for beam energies up to and beyond 250 MeV have been designed, constructed and are being planned. The mechanical alignment requirements will be discussed and compared with actual performance where available. The beam optics requirements will also be discussed and compared amongst different gantry designs
