Patent ID: 8748852

Claim:
An isocentric gantry designed for rotating around an axis of rotation and for delivering a particle beam for use in particle therapy, comprising: a gantry beam line having a gantry entrance point for entering said particle beam into the gantry in a direction essentially parallel with the axis of rotation; bending means for bending the particle beam in a single plane and delivering said particle beam at an isocenter in a direction essentially perpendicular to the axis of rotation, wherein said bending means include: first bending means configured for bending the particle beam away from said axis of rotation, second bending means configured for bending the particle beam towards the axis of rotation, and third bending means configured for bending the particle beam to said direction essentially perpendicular to the axis of rotation, said third bending means having a bending angle smaller than 80°; and particle beam scanning means installed in the beam line and configured for scanning said particle beam in both X and Y directions over a target area at the isocenter, wherein the scanning means is located between the second and the third bending means.
