The X-ray receptor 220 is mounted to the inner arc wall of the second C-arm 120 in the double C-arm support 100 by a third support 230. It should be noted that, in some embodiments of the present application, the X-ray imaging apparatus 200 may not be provided with the third support 230. Referring to embodiment 1, the structure and principle of the double C-arm support 100 will not be further explained in this embodiment.

The third support 230 is used to support the X-ray receiver 220. In the present embodiment, the third bracket 230 has a substantially rectangular shape. It should be noted that in other embodiments of the present application, the third support 230 may also be in the shape of an arc, a sphere, a triangle, etc.

Fig. 5 shows a schematic structural diagram of the X-ray receiver 220, the third bracket 230 and the second C-arm 120 in the X-ray imaging apparatus 200 provided in embodiment 2 of the present application. Referring to fig. 5, the third support 230 is rotatably connected to a third input 231 and a third output 232, so that the third output 232 can rotate around a connecting direction from the third input 231 to the third output 232, the third input 231 is connected to the inner arc wall of the second C-arm 120, and the third output 232 is connected to the X-ray receiver 220. When the third output end 232 rotates with the connection direction from the third input end 231 to the third output end 232 as the axis, the third output end 232 can drive the X-ray receiver 220 to rotate with the connection direction from the third input end 231 to the third output end 232 as the axis, so as to increase the freedom of movement of the X-ray imaging apparatus 200. It should be noted that, in some embodiments of the present application, the third bracket 230 may not be provided with the third input 231 and the third output 232 that rotate with each other.

In this embodiment, the third support 230 is a telescopic support, and when the third support 230 moves in a telescopic manner along its telescopic direction, the third support can drive the X-ray imaging apparatus 200 to move in a telescopic manner, so that the freedom of movement of the X-ray imaging apparatus 200 is increased, and the X-ray receiver 220 can reach more positions, thereby realizing more comprehensive imaging coverage.

The X-ray imaging device 200 provided by the embodiment of the application has the advantages of the double-C-shaped arm support 100. The X-ray generator 210 and the X-ray receiver 220 of the X-ray imaging device 200 can reach more positions, more comprehensive imaging coverage is facilitated, and more flexible operation in a single clinical environment is met.

Illustratively, the X-ray imaging apparatus 200 provided in the embodiment of the present application has a sliding angle of the first C-arm 110 relative to the first support 130 of 70 °, and a sliding angle of the second C-arm 120 relative to the first C-arm 110 of 140 °, such that the sliding angle of the second C-arm 120 relative to the first support 130 can reach 210 ° at most. The first output 132 may be rotated 270 ° with the connection direction of the first input 131 to the first output 132 as an axis, and the second output 142 may be rotated 300 ° with the connection direction of the second input 141 to the second output 142 as an axis. The third support 230 can be extended and contracted by 330mm, and the third output end 232 can be rotated by 180 degrees with the connecting direction of the third input end 231 to the third output end 232 as an axis. The first support 130 can move 1m along the extending direction of the fourth rail 172, and the first support 130 can move 2.4m along the extending direction of the third rail 171, so that the movement of the X-ray imaging device 200 in 8 degrees of freedom is realized, more comprehensive imaging coverage is facilitated, and more flexible operation in a single clinical environment is met.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
