Abstract: According to one embodiment of an X-ray imaging system, a column, including a first sub column, a second sub column, a third sub column, a first connector, and a second connector, supports an X-ray tube. The first connector connects the second sub column to the first sub column and includes a first rotation axis parallel to a short axis of a tabletop. The second connector connects the third sub column to the second sub column and includes a second rotation axis perpendicular to the first rotation axis and a central axis of the second sub column. The third sub column supports the X-ray tube.

Abstract: According to embodiment, an X-ray diagnostic apparatus includes a frame holding an X-ray tube and detector such that an axis connecting a X-ray focus and center of the detector rotates around an isocenter, display displaying a first image, operation circuitry inputting a position of a target region on the image, target position calculation circuitry calculating a position of the region on a second image based on an angle between the axes concerning the first and second images, a first distance from the isocenter to a top plate, and second distance from the target position to the plate, and top plate movement amount calculation circuitry calculating a top plate movement amount to display the region at a same position as the target position on the second image based on the calculated position, target position, angle, and first distance.

Abstract: An X-ray diagnostic device with a suspension mechanism for suspending an object in a vertically movable manner, using two suspension wires, which can avoid the shortened durability of the suspension wires, and using windup type springs, which can eliminate possibility for the fall of the suspended object due to the breaking of the windup type springs. The suspension mechanism may includes two suspension wires for holding the suspended object; and single threaded corn pulleys, one for each one of the two suspension wires, for winding the respective suspension wires. The suspension mechanism may also includes a plurality of windup type springs for balancing against gravitational force acting on the suspended object; connection between the plurality of windup type springs such that this connection moves when the plurality of windup type springs are put to be not balanced with respect to each other; and mechanism for preventing the fall of the suspended object by detecting motion of the connection.
