[0061] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0062] This embodiment provides an X-ray imaging device.

[0063] Please refer to Figures 1-9 , the X-ray imaging device includes a gantry assembly 100, a detection assembly 200, a collimator 120, and a display screen assembly 300.

[0064] Please refer to Figures 1-5 , the gantry assembly 100 includes a housing 110 and an X-ray source, and the X-ray source is disposed in the housing 110 for generating X-rays. The detection assembly 200 includes a flat panel detector (not shown) for receiving X-rays and generating a target image. The collimator 120 is connected to the gantry assembly 100, and the collimator 120 includes a lead window 123 and a lead window motor 122, and the lead window motor 122 is used to drive the lead window 123 to move to limit the irradiation range of the X-rays. The display screen assembly 300 includes a display screen 310 and a knob member 320, the display screen 310 includes a display area 311, and the display area 311 is at least used to display an operation interface 312. At least part of the knob member 320 is connected to the display area 311, and the knob member 320 is electrically connected to the lead window motor 122 to control the lead window 123 to limit the irradiation range of the X-rays.

[0065] In an actual application scenario, the user can operate the X-ray imaging device through the operation interface 312 of the display screen 310 and the knob member 320. Since at least part of the knob member 320 is connected to the display area 311 of the display screen 310, on the one hand, when the user operates the display screen 310 and the knob member 320, the hand only needs to move and operate on the display screen 310, thereby improving the convenience of the user operation. On the other hand, the display screen 310 does not block the user's line of sight when adjusting the knob member 320, thereby making the user's operation more intuitive.

[0066] Please refer to Figure 5, specifically, when it is necessary to adjust the irradiation range of the X-ray, that is, the so-called "radiation field", the user can control the lead window motor 122 to work through the knob member 320, drive the lead window 123 to move through the lead window motor 122, and thus limit the irradiation range of the X-ray through the lead window 123. The display screen 310 can be a touch display screen 310.

[0067] It should be noted that "at least part of the knob member 320 is connected to the display area 311" can be understood as at least part of the orthographic projection of the knob member 320 on the display screen 310 is located in the display area 311. The knob member 320 can be connected to the surface of the display screen 310 or embedded in the display screen 310, and the specific implementation scheme is not limited.

[0068] The display screen assembly 300 can be connected to one or more positions of the X-ray imaging device. For example, the display screen assembly 300 can be connected to the gantry assembly 100, the beam limiter 120, the first bracket 400, and / or the second bracket 500. Some optional installation positions, configuration quantities, and specific structures of the display screen assembly 300 will be exemplified below.

[0069] Please refer to Figures 1-5 , in one embodiment, the display screen assembly 300 is disposed on the gantry assembly 100 or the beam limiter 120.

[0070] Since the user usually stands near the gantry assembly 100 or the beam limiter 120 when operating the gantry assembly 100 or the beam limiter 120, it is convenient for the user to operate the display screen assembly 300 on the gantry assembly 100 or the beam limiter 120.

[0071] Please refer to Figures 1-3 , in one embodiment, the X-ray imaging device further includes a first bracket 400, the gantry assembly 100 is disposed on the first bracket 400, and the display screen assembly 300 is disposed on the first bracket 400.

[0072] The first bracket 400 realizes the support for the gantry assembly 100, and also enables the user to stand near the first bracket 400 when operating the gantry assembly 100, thus facilitating the user to operate the display screen assembly 300 on the first bracket 400.

[0073] Please refer to Figures 1-3 , in one embodiment, the first bracket 400 includes a vertical bracket and / or a suspended bracket.

[0074] Whether it is a vertical bracket or a suspended bracket, both can realize the support for the gantry assembly 100, and at the same time, both have the feasibility of installing the display screen assembly 300. Specifically, the vertical bracket can be a column, and the suspended bracket can be installed through a ceiling track.

[0075] Please refer toFigures 1-3 , in one embodiment, the X-ray imaging device further includes a second bracket 500, the detection component 200 is disposed on the second bracket 500, and the display screen component 300 is disposed on the second bracket 500.

[0076] The second bracket 500 supports the detection component 200, and enables the user to usually stand near the second bracket 500 when operating the detection component 200, thus facilitating the user to operate the display screen component 300 on the second bracket 500.

[0077] Please refer to Figures 3-5 , in one embodiment, the display screen component 300 further includes a first main control board 330, and the knob member 320 is electrically connected to the lead window motor 122 to control the lead window 123 to limit the irradiation range of the X-ray, including: the knob member 320 and the lead window motor 122 are electrically connected to the first main control board 330, and in response to the user's manipulation of the knob member 320, the first main control board 330 sends a control signal to the lead window motor 122 to control the lead window motor 122 to drive the lead window 123 to move to limit the irradiation range of the X-ray.

[0078] When the user needs to control the beam limiter 120 to work, the user inputs a trigger signal to the first main control board 330 through the knob member 320. After receiving the trigger signal, the first main control board 330 sends a control signal to the beam limiter 120 to control the beam limiter 120 to work. Specifically, when the user needs to adjust the X-ray field of view, the user can rotate and / or press the knob cap 322, thereby inputting a trigger signal to the first main control board 330. After receiving the trigger signal, the first main control board 330 sends a control signal to the lead window motor 122, and after receiving the control signal, the lead window motor 122 drives the lead window 123 to move, thereby realizing the adjustment of the X-ray field of view.

[0079] Please refer to Figures 3-5 , in one embodiment, the knob member 320 includes a knob base 321 and a knob cap 322. The knob base 321 is connected to the display screen 310, and the knob cap 322 is movably connected to the knob base 321. The user can rotate and / or press the knob cap 322 to manipulate the knob member 320.

[0080] Enables the user to manipulate the knob member 320 by rotating and / or pressing the knob cap 322. The operation method is simple, and a combination of these two operation methods can be used to operate a variety of complex functions, which will be described in detail in conjunction with actual application scenarios later.

[0081] Please refer to Figures 3-5, in one embodiment, the collimator 120 further includes a second main control board 121. The first main control board 330 is electrically connected to the second main control board 121. The first main control board 330 sends a control signal to the lead window motor 122 to control the lead window motor 122 to drive the lead window 123 to move so as to limit the irradiation range of the X-ray, including: based on the control signal sent from the first main control board 330 to the second main control board 121, the second main control board 121 sends a control signal to the lead window motor 122 to control the lead window motor 122 to drive the lead window 123 to move through the transmission connection between the lead window motor 122 and the lead window 123 so as to block at least part of the X-ray.

[0082] When the user needs to adjust the X-ray field of view, the user can rotate and / or press the knob cap 322, thereby inputting a trigger signal to the first main control board 330. After receiving the trigger signal, the first main control board 330 sends a first control signal to the second main control board 121. After receiving the first control signal, the second main control board 121 sends a motor drive signal to the lead window motor 122. After receiving the motor drive signal, the lead window motor 122 drives the lead window 123 to move, thereby realizing the adjustment of the X-ray field of view.

[0083] Please refer to Figures 3-5 , in one embodiment, the collimator 120 further includes a projection device 124 electrically connected to the second main control board 121. The projection device 124 includes a projector and / or a visible light source. The lead window motor 122 is controlled to drive the lead window 123 to move through the transmission connection between the lead window motor 122 and the lead window 123 so as to block at least part of the projection light of the projection device 124, thereby realizing the adjustment of the "light field" of the projection. It should be noted that the "light field" indicates the range of the "field of view" through visible light. Under normal circumstances, the light field range and the field of view range are the same.

[0084] When the user needs to adjust the projection range of the projection device 124, the user can input a trigger signal to the lead window motor 122 through the knob member 320, and control the lead window motor 122 to drive the lead window 123 to move through the transmission connection between the lead window motor 122 and the lead window 123 so as to block at least part of the projection light of the projection device 124, thereby adjusting the projection range of the projection device 124.

[0085] In an actual application scenario, when the user needs to control the projection device 124 of the collimator 120 to work, the user can rotate and / or press the knob cap 322, thereby inputting a trigger signal to the first main control board 330. After receiving the trigger signal, the first main control board 330 sends a second control signal to the second main control board 121. After receiving the second control signal, the second main control board 121 sends a projection working signal to the projection device 124, thereby controlling the projection device 124 to work. Specifically, the working modes of the projection device 124 include but are not limited to projecting images and / or videos, and switching the projected images and / or videos, etc.

[0086] Please refer to Figures 3-5 , in one embodiment, the display screen 310 further includes a non-display area 313 surrounding the display area 311. The knob member 320 is installed in the non-display area 313, and at least a part of the knob member 320 extends into the display area 311.

[0087] On the one hand, since the knob member 320 is installed in the non-display area 313, it is beneficial to reduce the space occupied by the knob member 320 in the display area 311, thereby reducing the influence of the knob member 320 on the display effect of the display area 311. On the other hand, since at least a part of the knob member 320 extends into the display area 311, it provides a hardware basis for subsequent realization of the interaction between the knob member 320 and the display area 311. Specifically, the non-display area 313 can be understood as the so-called "black edge of the display screen".

[0088] Please refer to Figures 3-7 , in one embodiment, the knob member 320 further includes a mounting structure 340. The knob member 320 is fixed to the display screen 310 through the mounting structure 340. In an actual application scenario, the knob member 320 can be fixed by making the mounting structure 340 pass through the display screen 310 by way of opening a mounting hole 314 in the non-display area 313 of the display screen 310.

[0089] Please refer to Figures 3-7 , since the through mounting hole 314 is provided on the display screen 310, on the one hand, the wires of the knob member 320 can pass through the mounting hole 314 to facilitate the routing of the wires on the back side of the display screen 310. On the other hand, the mounting structure 340 can pass through the mounting hole 314 to facilitate the installation of the knob member 320 on the display screen 310 through the mounting structure 340.

[0090] Please refer to Figures 3-7 , in one embodiment, the mounting hole 314 includes a first mounting hole 3141. At least a part of the mounting structure 340 passes through the first mounting hole 3141 and is connected to the knob member 320 to mount the knob member 320 on the touch screen.

[0091] When installing the knob member 320, the installer can place the knob member 320 at one end of the first mounting hole 3141, and then pass the mounting structure 340 through the first mounting hole 3141 from the other end of the first mounting hole 3141, and connect the mounting structure 340 with the knob member 320, so as to install the knob member 320 on the touch screen through the mounting structure 340. Specifically, the first mounting hole 3141 passes through the display side of the touch screen, the knob member 320 is connected to one end of the first mounting hole 3141 located on the display side, and the mounting structure 340 extends into the first mounting hole 3141 from one end of the first mounting hole 3141 located on the back side. The mounting structure 340 may include a mounting screw 341, a mounting pin shaft, or other suitable mounting structures 340.

[0092] The mounting structure 340 is threadedly connected to the knob member 320 because the threaded connection is relatively stable and can be easily realized through a through fitting.

[0093] Please refer to Figures 3-7 In one embodiment, the mounting structure 340 includes a mounting screw 341, a screw column (not shown) on the knob member 320, and a mounting sleeve 342. The screw column of the knob member 320 also has a screw hole (not shown). The screw column passes through the first mounting hole 3141, the mounting sleeve 342 is arranged on the side of the display screen 310 away from the knob member 320 and is fixedly sleeved on a part of the screw column by the mounting screw, and the mounting screw 341 extends into the screw hole, so that the knob member 320 is mounted on the display screen 310 through the mounting structure 340.

[0094] Of course, in other embodiments, the knob 320 may be installed on the display screen 310 by means of an adhesive structure or a buckle structure, and the knob 320 may also be wirelessly connected to the first main control board 330.
