  • Patent number: 11813097
    Abstract: A compression tube attaching-detaching unit is provided with an arm, a connecting pin, and an attaching-detaching mechanism portion. The arm supports a compression tube. The attaching-detaching mechanism portion is removably coupled with the connecting pin to mount the arm on a radiographic fluoroscopic imaging apparatus. The connecting pin has a shaft portion and a flange portion positioned at the tip end of the shaft portion. The attaching-detaching mechanism portion includes a main body, a lid portion, a locking portion, and an unlocking portion.

  • Patent number: 11786189
    Abstract: An X-ray shielding unit 19 includes a plurality of shielding slats, freely movable with an imaging system that is in place above a table, and each free end of the shielding slats extends toward the table and is the slats are arrayed in parallel along the long side of the table. A shielding switching element switches the X-ray shielding unit between a shielding state in which the X-ray exposure to the operator S is blocked and a releasing state. The shielding switching element includes a slat rotation mechanism rotating respective shielding slats on a short side axis of the table, and the slat rotation mechanism rotates the shielding slats during switching of the shielding state.

  • Patent number: 10568590
    Abstract: A radiation imaging apparatus adds a compression force to the subject and a belt 31 separated from the surface of a table 13 moves to a lifting position by providing the belt 31 with tension and rotation of a wind-up roller 34 wherein in use belt 31 lifts from the surface of the table 13 and compresses the abdomen of the subject M and, after rotation of the wind-up roller 34 ends X-ray imaging occurs.
