摘要： A multileaf collimator (60A) includes leaves (70) that extend in a first direction; a frame (61) that supports the plurality of leaves (70) so that the plurality of leaves (70) are advanceable and retractable in a state where the plurality of leaves (70) are placed side by side in a second direction perpendicular to the first direction; a plurality of shafts (95) that extend in the second direction and are provided to correspond to the plurality of leaves (70), respectively; a plurality of driving units (91) that are respectively connected to base ends of the plurality shafts and rotate the shafts (95) around axial lines; and driving units (91) that are provided at tips of the shafts (95), contact portions of the leaves (70), and advance and retract the leaves (70) in the first direction by the rotation of the shafts (95) around the axial lines. At least some of the plurality of shafts (95) have the same shaft (95) length as each other. The plurality of driving units (91) are arranged so that the positions thereof in the second direction are shifted from each other according to the positions of the tips of the plurality of shafts (95) having the same length.

摘要： A radiation therapy apparatus (20) includes: an annular gantry (30); an irradiation unit (24) which is provided on the gantry (30) and configured to radiate radiation; a support (42A) which supports the gantry (30); a rotation-driving mechanism (40A) which is provided between the gantry (30) and the support (42A) and rotates the gantry (30) around a horizontal central axis (C1) of the gantry (30). The rotation-driving mechanism (40A) includes: annular rails (41) that are provided on the gantry (30); and sliding members (45A) which are provided on regions of the support (42A) that correspond to a lower half of the gantry (30), slidably guide the rails (41), and receive at least a load of the gantry (30) in a vertical direction.
