Abstract

An X-ray imaging includes an X-ray radiation source. The X-ray imaging system also includes an X-ray detector. The X-ray imaging system further includes a gantry structure configured to be mounted to a ceiling or a floor. The gantry structure includes a C-arm having the X-ray radiation source disposed on a first end and the X-ray detector disposed on a second end opposite the first end. The gantry structure also includes a C-arm rotation device coupled to the C-arm and configured to rotate the C-arm relative in an orbital direction relative to the C-arm rotation device. The X-ray imaging system also includes a damping system coupled to the gantry structure and disposed between the gantry structure and the ceiling or the floor, wherein the damping system is configured to dampen vibrations caused by motion of the gantry structure for an entirety of the gantry structure.

Claims (36)

1 . An X-ray imaging system, comprising:

an X-ray radiation source;

an X-ray detector;

a gantry structure configured to be mounted to a ceiling or a floor, wherein the gantry structure comprises:

a C-arm having the X-ray radiation source disposed on a first end and the X-ray detector disposed on a second end opposite the first end; and

a C-arm rotation device coupled to the C-arm and configured to rotate the C-arm in an orbital direction relative to the C-arm rotation device; and

a damping system coupled to the gantry structure and disposed between the gantry structure and the ceiling or the floor, wherein the damping system is configured to dampen vibrations caused by motion of the gantry structure for an entirety of the gantry structure, and wherein the damping system comprises a swivel bearing and a damping mechanism.

2 . The X-ray imaging system of claim 1 , wherein the damping mechanism comprises a body having a third end and a fourth end opposite the third end, a first damper connection disposed on the third end, and a second damper connection coupled to the fourth end.

3 . The X-ray imaging system of claim 2 , wherein both the first damper connection and the second damper connection both directly contact both the gantry structure and the body.

4 . The X-ray imaging system of claim 2 , wherein the first damper connection comprises one or more damping pads.

5 . The X-ray imaging system of claim 2 , wherein the second damper connection comprises a shaft and bushings coupled to opposite ends of the shaft, and wherein the shaft extends through a portion of the gantry structure.

6 . The X-ray imaging system of claim 2 , wherein the swivel bearing is disposed on a surface of the body facing the floor when the gantry structure is mounted to the floor.

7 . The X-ray imaging system of claim 2 , wherein the swivel bearing is disposed on a surface of the body facing the ceiling when the gantry structure is mounted to the ceiling.

8 . The X-ray imaging system of claim 2 , wherein the body is made of a material that is at least times stiffer than both the first damper connection and the second damper connection.

9 . The X-ray imaging system of claim 1 , wherein the swivel bearing is configured to enable the gantry structure to rotate 360 degrees about a rotational axis of the swivel bearing.

10 . The X-ray imaging system of claim 1 , wherein the damping system is configured to dampen the vibrations for the entirety of gantry structure along multiple directions.

11 . The X-ray imaging system of claim 10 , wherein the multiple directions comprise orthogonal directions, and wherein the orthogonal directions comprise a vertical direction extending between the floor and the ceiling and a horizontal direction that is both perpendicular to the vertical direction and parallel with the floor.
