Compact Gantry System for the Irradiation of Lying Patient by Proton/Ion   beam
  We describe here a compact gantry system, when the lying patient is slowly moved in horizontal and vertical directions in accordance with rotation of transport channel around its axis so that the region, irradiated from different directions, stays in a focus of beam optical system. By this combination of rotation of magnets and linear motion of patient it becomes possible to simplify magnetic system significantly.
