Gantry structure for hadron therapy device

摘要

In addition to rotation about a rotation axis (18), configured gantry structure to provide a hadron beam to a target (16) receives the rotation axis (18) essentially parallel to the direction of the hadron beam , deflect it away from the axis of rotation (18), and I comprises an beam delivery line (24) for transmitting it as the axis of the beam intersects the rotational axis (18). Beam transmission line (24) is a self-supporting structure that is supported by a center of gravity near in pivotable support arms of the beam delivery line (24) (32). Counterweight (42) is supported in order to compensate the moment of the weight by the force of the beam delivery line (24) and the support arm (32), the other side in the support arm extension of the rotational axis (18) (40) differentially.
