The supporting parts of a gantry (1, 2) are situated substantially radially with respect to the longitudinal axis. The gantry includes an inner gantry part (1) with at least two supporting locations (S) to an outer gantry portion (2).The support locations (S) are situated at each side of a treatment volume (12). A radiation head (8), mechanically attached to the inner gantry part (1) and arranged to direct radiation to the treatment volume (12) is movable around the treatment volume (12). In preferred embodiments, the parts (20, 21, 22, 23) of the gantry are formed as rings, leaving a free space along the rotational axis (9). A body-supporting couch (10) is arranged along the rotational axis extending through the hollow parts (20, 21, 22, 23). The radiation head (8) is preferably movable in a path also perpendicular to the rotation axis (9).Other References
