The present invention limits rotation-related loads on a mechanism. In an x-ray diagnostic device according to the present embodiment, an x-ray generating unit (15) generates x-rays. An x-ray detection unit (18) detects the x-rays generated by the x-ray generating unit (15) and transmitted through a subject. A C-shaped arm (11) holds the x-ray generating unit (15) and the x-ray detection unit (18) so that the x-ray generating unit (15) and the x-ray detection unit (18) face each other. A movement unit (19) moves the C-shaped arm (11) around a plurality of rotational axes. A sequence setting unit (24) sets an imaging sequence for a plurality of left-eye imaging positions with respect to a subject and for a plurality of right-eye imaging positions that respectively correspond to the plurality of left-eye imaging positions. A mechanism control unit (25) controls the movement unit (19) to move the C-shaped arm (11) according to the imaging sequence that has been set. The imaging sequence includes a sequence in which images are captured in succession from at least two imaging positions among a plurality of left-eye imaging positions or a sequence in which images are captured in succession from at least two imaging positions among a plurality of right-eye imaging positions.La présente invention concerne une limitation des charges associées à une rotation dun mécanisme. Dans un dispositif de radiodiagnostic selon un mode de réalisation de la présente invention, une unité génératrice de rayons X (15) génère des rayons X. Une unité de détection de rayons X (18) détecte les rayons X générés par lunité génératrice de rayons X (15) et dont lémission traverse un sujet. Un bras en forme de C (11) maintient lunité génératrice de rayons X (15) et lunité de détection de rayons X (18) de sorte que lunité génératrice de rayons X (15) et lunité de détection de rayon X (18) se font face. Une unité de déplacement (19) déplace le bras en forme de C (11) suivant plusieurs axes de rotation.
