In this way, the X-ray emitted from the tube passes through the patient's lesion after adjusting the light field and hits the receiving plate of the CCD detector. After digital processing, the image of the lesion is obtained.

[0048] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0049] like Figures 1 to 5As shown, this embodiment provides a suspended DR system 100, which includes a suspension body 1, a horizontal moving device 2 and a rotating device 4. The suspension body 1 includes a connecting end 13 and a moving end 12. The connecting end 13 is used to connect the X-ray tube 3. The horizontal moving device 2 is connected to the moving end 12 and is used to drive the suspension body 1 to move in a first direction. The rotating device 4 is used to drive the connecting end 13 to rotate relative to the moving end 12, wherein the first direction is not perpendicular to the rotation plane of the connecting end 13. Specifically, the movement in the first direction can be achieved by the horizontal moving device 2 driving the suspension body 1 to move, so that the horizontal moving device 2 can drive the X-ray tube 3 to move in the first direction. The rotating device 4 drives the connecting end 13 to rotate, thereby realizing the rotational movement of the X-ray tube 3 in the rotation plane. In addition, the horizontal moving device 2 can drive the connection end 13 to move along the first direction and the rotating device 4 can drive the connection end 13 to rotate to cooperate to achieve movement in a direction that is angled with the first direction, thereby achieving movement of the X-ray tube 3 connected to the connection end 13 at any position in space, so that the medical staff can freely and comprehensively adjust the position of the X-ray tube 3 in space, and the X-ray tube 3 can cooperate with the lifting bed 200 and the chest radiograph stand 300 to meet the requirements of supine shooting and stereoscopic shooting of patients. In other words, when the X-ray tube 3 needs to move in the first direction, it can be achieved by driving the suspension body 1 to move by the horizontal moving device 2; when the X-ray tube 3 needs to rotate, it can be driven by the rotating device 4 to rotate the connection end 13 relative to the moving end 12 to achieve the rotation of the X-ray tube 3 relative to the moving end 12; when the X-ray tube 3 needs to move in a direction that is angled with the first direction, it can be achieved by the coordinated movement of the suspension body 1 driven by the horizontal moving device 2 and the rotation of the X-ray tube 3 relative to the moving end 12 by the rotating device 4. The above-mentioned structural form can achieve space saving and greatly simplify the structure of the suspended DR system 100, so that more complex motion requirements can be achieved with a simpler design, which greatly improves the position accuracy and reliability of the suspended DR system 100.

[0050] In actual use, in order to improve the movement accuracy of the X-ray tube 3 in a direction that is angled with the first direction, it is preferred that the first direction is parallel to the rotation plane of the connection end 13 .

[0051] like Figure 2 and Figure 5 As shown, in this embodiment, the first direction is the X direction, and the direction at an angle to the first direction is the Y direction. In other embodiments, the first direction can be adjusted according to actual needs and is not limited here.

[0052] See also Figures 1 to 5As shown, the suspension body 1 includes a first body 11 and a second body 14, a rotating device 4 is disposed between the first body 11 and the second body 14, so that the first body 11 and the second body 14 generate relative rotation, a connecting end 13 is disposed on the second body 14, and a moving end 12 is disposed on the first body 11. With the above-mentioned structural form, the first body 11 can generate relative rotation relative to the second body 14 through the rotating device 4, thereby realizing the relative rotation of the connecting end 13 relative to the moving end 12, and then the X-ray tube 3 can be driven to perform rotational movement through the connecting end 13, thereby improving the movement range of the X-ray tube 3.

[0053] The rotating device 4 includes a first rotating hole 41 and a first rotating shaft 42. The first rotating shaft 42 extends into the first rotating hole 41 and is rotatably connected to the first rotating hole 41. One of the first rotating shaft 42 and the first rotating hole 41 is provided on the first body 11, and the other is provided on the second body 14. The extending direction of the first rotating shaft 42 is not parallel to the first direction. Specifically, through the rotatable connection between the first rotating hole 41 and the second rotating shaft, the first body 11 can rotate relative to the second body 14, thereby realizing the rotational movement of the connecting end 13 relative to the moving end 12, and then the X-ray tube 3 can be driven to rotate through the connecting end 13, thereby increasing the movement range of the X-ray tube 3.

[0054] In this embodiment, the first body 11 is provided with a first rotating shaft 42, the second body 14 is provided with a first rotating hole 41, and the first rotating shaft 42 extends into the first rotating hole 41 and rotates with the first rotating hole 41 along the extension direction of the first rotating shaft 42, thereby realizing the rotation of the first body 11 relative to the second body 14. In other embodiments, the first rotating hole 41 may be provided on the first body 11, and the first rotating shaft 42 may be provided on the second body 14. Of course, in other embodiments, the first body 11 may be provided with a connecting hole, and the second body 14 may be connected with a rotating frame. An accommodating cavity is provided at one end of the rotating frame close to the first body 11, and one end of the first body 11 with the connecting hole extends into the accommodating cavity, and the rotating shaft passes through the rotating frame and the connecting hole, so that the first body 11 can rotate relative to the rotating frame in the accommodating cavity.

[0055] The first body 11 and the first rotating shaft 42 can be integrally formed, thereby improving the structural strength of the first body 11. In other embodiments, the first body 11 and the first rotating shaft 42 are separately provided, and the first body 11 and the first rotating shaft 42 are detachably connected, so that if one of the first body 11 and the first rotating shaft 42 is damaged, it is only necessary to replace the damaged first body 11 or the first rotating shaft 42, and the above-mentioned structural form facilitates the processing of the first body 11 and the first rotating shaft 42. In addition, in this embodiment, the extension direction of the first rotating shaft 42 is perpendicular to the first direction, so that the first direction is parallel to the rotation plane of the connection end 13, thereby improving the movement accuracy of the X-ray tube 3 in the direction at an angle to the first direction.

[0056] The second body 14 includes a telescopic cylinder, one end of which is rotatably connected to the first body 11, and the other end of which is connected to the X-ray tube 3, and the telescopic cylinder is used to drive the X-ray tube 3 to move in the vertical direction. Specifically, the position of the X-ray tube 3 in the vertical direction can be adjusted by the telescopic cylinder, so that the positional relationship between the X-ray tube 3 and the lifting bed 200 can be adjusted, and the two adjacent telescopic joints can drive each other to slide up and down synchronously, so as to adjust the distance between the X-ray tube 3 and the patient on the lifting bed 200 in the vertical direction. The above-mentioned structural form is adopted to further improve the movement range of the X-ray tube 3, and improve the adaptation range of the X-ray tube 3 and the lifting beds 200 of different heights, so that the position of the X-ray tube 3 in space meets the needs of different clinical conditions.

[0057] The telescopic cylinder includes a plurality of telescopic joints, which are slidably nested in sequence along the vertical direction, the telescopic joint close to the first body 11 is rotatably connected to the first body 11, and the telescopic joint close to the X-ray tube 3 is connected to the X-ray tube 3. With the above-mentioned structural form, there is a certain height difference between two adjacent telescopic joints, so that the function of the plurality of telescopic joints performing telescopic actions in order is realized, and the telescopic action of the telescopic cylinder is coherent and stable.

[0058] In this embodiment, in order to further increase the adjustable range of the length of the telescopic tube, it is preferred that the outer diameters of the plurality of telescopic sections decrease from top to bottom, and the telescopic sections are in the shape of a hollow tube.

[0059] Two adjacent telescopic joints are connected by bearing sliding, which reduces the friction force of the entire telescopic tube when it is extended and retracted, and prolongs the service life of the telescopic tube. In other embodiments, two adjacent telescopic joints can also be connected by guide wheels sliding.

[0060] The X-ray tube 3 is rotatably connected to the second body 14; wherein the rotation plane of the X-ray tube 3 is not perpendicular to the rotation plane of the connection end 13. Specifically, one of the telescopic tube and the X-ray tube 3 is provided with a second rotation hole, and the other of the telescopic tube and the X-ray tube 3 is provided with a second rotation shaft, which extends into the second rotation hole and is rotatably connected to the second rotation hole; wherein the extension direction of the second rotation shaft is not perpendicular to the rotation plane of the connection end 13.

[0061] In specific use, the rotating device 4 drives the connection end 13 to rotate relative to the moving end 12, so that the X-ray tube 3 can be driven by the moving end 12 to realize rotation in the rotation plane; in addition, the extension direction of the second rotating shaft is not perpendicular to the rotation plane of the connection end 13, so that when the X-ray tube 3 rotates along the extension direction of the second rotating shaft, its rotation plane is not parallel to the rotation plane of the connection end 13. That is, the X-ray tube 3 can rotate in the rotation plane of the connection end 13, or it can rotate along the extension direction of the second rotating shaft, and the rotation plane of itself rotating along the extension direction of the second rotating shaft is not parallel to the rotation plane of the connection end 13. With the above-mentioned structural form, the rotation of the X-ray tube 3 relative to the connection end 13 is realized through the second rotating hole and the second rotating shaft, and the rotation plane of the X-ray tube 3 is not parallel to the rotation plane of the connection end 13, which further increases the rotation range of the X-ray tube 3, so that the position of the X-ray tube 3 in space meets the needs of different clinical conditions.

[0062] In this embodiment, the rotation plane of the X-ray tube 3 relative to the connection end 13 is perpendicular to the rotation plane of the connection end 13, so that the X-ray tube 3 can rotate freely in the horizontal plane and the vertical plane, thereby quickly adjusting the spatial position of the X-ray tube 3 to meet the needs of different clinical conditions.

[0063] like Figures 1 to 5 As shown, the horizontal moving device 2 includes a matching portion 21 and a guide portion 22 extending along the first direction, the matching portion 21 matches the guide portion 22, and one of them is arranged on the connection end 13, and the other is arranged on the mounting surface. The mounting surface referred to above is the mounting surface of the horizontal moving device 2. With the above structural form, the guide portion 22 can provide guidance for the movement of the moving end 12, so that the suspension body 1 can accurately move along the first direction, thereby improving the stability of the movement of the suspension body 1.

[0064] In this embodiment, the guide portion 22 is installed on the installation surface, and the matching portion 21 is installed on the connection end 13. In addition, along the first direction, the matching portion 21 and the guide portion 22 are provided on both sides of the connection end 13, thereby further improving the stability of the movement of the suspension body 1.

[0065] The matching portion 21 includes a roller, the guiding portion 22 includes a guide rail extending along the first direction, the roller is connected to the connecting end 13, the guide rail is arranged on the mounting surface, and the roller is slidably connected to the guide rail. With the above-mentioned structural form, the friction of the suspension body 1 is reduced through the sliding connection between the roller and the guide rail, and the service life of the suspension body 1 and the guide rail is increased.
