Abstract: An X-ray imaging apparatus is provided with an X-ray source, a detector, a C-shaped arm, a hose for accommodating wiring, the hose including a base side portion and an opposite side portion, a base including a C-shaped arm support portion and a hose attachment portion to which the base side portion is rotatably attached, a biasing member for biasing the base side portion of the hose to rotate about the hose attachment portion in the first rotation direction outwardly away from the C-shaped arm, and an image processing unit.

Abstract: An arm moving mechanism 200 includes a first rotatable member 26 mounted on base 27 so as to be rotatable about a first rotation axis 31 perpendicular to the base 27, a second rotatable member 25 mounted on the first rotatable member 26 so as to be rotatable about a second rotation axis 32 perpendicular to the base 27, a C-shaped arm support frame 24 mounted on the second rotatable member 25 so as to be rotatable about a third rotation axis 33 perpendicular to the base 27, motors for rotating them, and a controller for controlling the motors. When the first rotatable member 26, the second rotatable member 25, and the C-shaped arm support frame 24 are moved, the radiation irradiation unit 11 and the radiation detection unit 14 are moved linearly between the imaging position for performing radiographic imaging and the retreat position retreated from the imaging position.

Abstract: This X-ray fluoroscopic imaging apparatus includes a first arm, a second arm, and a controller. The controller is configured to move a second base to move the second arm to a position where the second arm does not interfere with the first arm when the first arm and the second arm interfere with each other and change the angle of the second arm so that the angle of the second arm becomes a predetermined imaging angle to arrange the first arm and the second arm at positions where the first arm and the second arm do not interfere with each other to perform imaging.

Abstract: A storage unit 2 arranged on a foot side of a subject placed on a top board is provided with a box composed of a block member 22 and a plate member 23 and a lid 21 covering an upper side of the box. The lid 21 is provided so as to be capable of pivoting about a shaft 20 relative to the plate member 23 of the box composed of the block member 22 and the plate member 23. When the lid 21 is in a closed state, the upper portion of the plate member 23 of the box composed of the block member 22 and the plate member 23 is covered by the lid 21. In this state, as shown in FIG. 2, the upper surface of the lid 21 and the surface of the top board of the storage unit 2 are arranged at the same height, and are thus coplanar.

Abstract: An X-ray fluoroscopic imaging apparatus is capable of easily setting a region of interest and maintaining a source object distance, such as in cases where a mechanism for moving a top board upward and downward is not provided or even in cases where it is desired to perform control without moving the top board upward and downward. In some examples, a C-arm supports an X-ray tube and a flat panel detector to face each other. An examination table equipped with a movable top board is movable in a longitudinal direction and inclinable. The movable top board may be moved in the longitudinal direction in a state in a which an inclination angle is maintained until a position in a perpendicular direction with respect to the movable top board after inclination changed matches a position in the perpendicular direction with respect to the movable top board before the inclination with respect to a height in the vertical direction and move a C-arm by a distance moved in parallel to a horizontal plane.

Abstract: An X-ray fluoroscopy and imaging and apparatus prevents error in a foot switch having a sensor. The detection sensor detects whether the operator is contacting each switch installed on the foot-switch. The information detected by the sensor is displayed as a textual format and/or an image that are visually recognizable, so that the operator can confirm the accuracy of a contacted-switch indication. Accordingly, the operator can comprehend instantly and accurately information relative to the switch currently selected.
