The present application provides a neutron capture therapy system. The neutron capture therapy system is provided with a neutron generating device for generating a neutron beam, an irradiation chamber for irradiating an irradiated body with a neutron beam, and a placement table housed in the irradiation chamber and used for placing the irradiated body. The placement table comprises a placement member for placing a patient, an adjustment device for adjusting the spatial position of the placement member, a driving rod connected between the adjustment device and the placement member, and a first shielding member wrapping the adjustment device, the first shielding member preventing the adjustment device from being radiated by radioactive rays. The adjustment device drives the driving rod to move so as to adjust the spatial position of the placement member, and the first shielding member is provided with a through slot for providing a receiving space for the movement of the driving rod. The adjustment device is disposed inside the basically-sealed first shielding member, so that the radiation damage on the adjustment device caused by neutrons and gamma rays is greatly reduced, and the service life of the adjustment device is prolonged.La présente invention concerne un système de thérapie par capture de neutrons. Le système de thérapie par capture de neutrons est pourvu d'un dispositif de génération de neutrons pour générer un faisceau de neutrons, d'une chambre d'irradiation pour irradier un corps irradié avec un faisceau de neutrons, et d'une table de placement logée dans la chambre d'irradiation et utilisée pour placer le corps irradié. La table de placement comprend un élément de placement pour placer un patient, un dispositif de réglage pour ajuster la position spatiale de l'élément de placement, une tige d'entraînement reliée entre le dispositif de réglage et l'élément de placement, et un premier élément de blindage enveloppant le dispositif de réglage, le premier é
