Description

Technical Field

[0001] This utility model relates to the field of X-ray imaging technology, specifically to a radiation source mounting structure, and an X-ray imaging device and a breast CT including the radiation source mounting structure. Background Technology

[0002] In breast CT scans, the X-ray source and detector are two core components, each playing a crucial role. The X-ray source is the device that emits the X-ray beam during a CT scan. The X-ray beam emitted from the X-ray tube penetrates the breast tissue, forming a planar projection image of the breast. The detector, located opposite the X-ray source, is responsible for receiving the X-rays that have passed through the breast tissue and converting them into electrical signals. Therefore, the X-ray source is responsible for emitting X-rays and is the origin of the final CT image.

[0003] Therefore, the performance and installation stability of the radiation source in breast CT are important factors affecting the quality of CT imaging. Existing radiation sources are generally set on a rotating platform relative to the detector, and the rotating platform is used to rotate around the patient. However, the position of existing radiation sources is mostly fixed, so it is impossible to make adaptive adjustments according to the shape and orientation of the object being measured, which has certain defects in terms of imaging convenience and accuracy. Summary of the Invention

[0004] This utility model provides a radiation source mounting structure. By utilizing the mounting ramp, the adapter component, and the position adjustment of the mounting plate itself, the spatial position of the radiation source on the mounting ramp can be adjusted. With the use of a small number of parts, the spatial position of the radiation source is ensured to be in the optimal orientation, eliminating the need for complex adjustment mechanisms and processes.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A radiation source mounting structure, comprising:

[0007] The bracket, the top of which is provided with a mounting ramp for placing the radiation source; and

[0008] The mounting plate is disposed on the mounting slope. A transition component is provided between the mounting plate and the source, which can drive the source to rotate along the mounting plate to achieve left and right sway of the source. The mounting plate can move freely along the mounting slope to adjust the horizontal twist of the source along the mounting slope.

[0009] Preferably, the source mounting structure further includes a support base disposed at the bottom of the side of the source away from the mounting plate.

[0010] Preferably, the bracket includes a back panel, side panels symmetrically arranged on both sides of the back panel, a front panel parallel to the back panel and arranged on the sides of the side panels, and an inclined panel arranged on the top of the back panel, side panels and front panel.

[0011] Preferably, the back panel, side panel, front panel, and slanted panel are each provided with a number of perforated holes.

[0012] Preferably, the mounting plate includes a horizontal plate disposed on the mounting slope and a vertical plate fixed to the top of the horizontal plate.

[0013] Preferably, the vertical plate and the horizontal plate form an inverted T-shaped structure.

[0014] Preferably, the mounting plate further includes ribs disposed between the side walls of the horizontal plate and the vertical plate.

[0015] Preferably, the adapter assembly includes a rotating seat rotatably disposed on the side wall of the vertical plate, and the end of the rotating seat away from the vertical plate is fixedly connected to the radiation source.

[0016] Preferably, the vertical plate is provided with a plurality of first mounting holes that mate with the radiation source.

[0017] Preferably, the horizontal plate is provided with a second mounting hole for fixing the horizontal plate to the top of the bracket.

[0019] A breast CT scanner, including the aforementioned radiation source mounting structure.

[0020] As can be seen from the above technical solutions, this utility model has the following beneficial effects:

[0021] 1. In this utility model, when it is necessary to adjust the tilt angle of the radiation source, the tilt angle of the mounting slope can be changed by design to indirectly adjust the tilt position of the radiation source; when it is necessary to adjust the left and right sway angle of the radiation source, the radiation source is driven to rotate around the adapter component as the rotation center, and the radiation source then deflects within a small range relative to the mounting plate to adjust the left and right sway angle of the radiation source itself; when it is necessary to adjust the horizontal torsion angle of the radiation source, the mounting plate can be moved and rotated at a certain angle along the top of the mounting slope, thereby driving the radiation source connected to the mounting plate to rotate horizontally. This application utilizes the aforementioned mounting slope, adapter component, and the position adjustment of the mounting plate itself to achieve the purpose of adjusting the spatial position of the radiation source on the mounting slope, making full use of the spatial relationship coupling between the bracket and its components, ensuring that the spatial position of the radiation source is in an optimal orientation with a small number of parts, and reducing the complexity of the adjustment mechanism and adjustment process.

[0022] 2. In this utility model, one end of the source is rotatably connected to the mounting plate via an adapter assembly, and the other end is connected to the bracket via a support base. The adapter assembly can be used to achieve left and right tilting of the source, and the mounting plate can be used to achieve horizontal tilting of the source by twisting along the mounting slope. Therefore, the mounting plate in this application not only has a supporting function, but also plays a role in adjusting the orientation of the source. Attached Figure Description

Detailed Implementation

[0027] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1 A source mounting structure includes a bracket 10 and a mounting plate. The top of the bracket is provided with a mounting slope 110 for placing a source 50. The mounting plate is disposed on the mounting slope 110. It should be noted that the angle of the mounting slope at the top of the bracket can be set according to actual usage requirements, that is, the aforementioned mounting slope angle can be adaptively adjusted during the design and production process. At the same time, in order to achieve left and right tilting of the source, a transition component is provided between the mounting plate and the source. This transition component can drive the source to rotate along the mounting plate 20, thereby achieving left and right tilting of the source. Furthermore, the mounting plate 20 can move freely along the mounting slope 110. Specifically, it can be horizontally twisted at a certain angle along the mounting slope and then fixed to adjust the horizontal orientation of the source along the mounting slope. It can be seen that by utilizing the aforementioned mounting slope, adapter components, and the position adjustment of the mounting plate itself, this application can achieve the purpose of adjusting the spatial position of the source on the mounting slope. It makes full use of the spatial relationship coupling between the bracket and its components, and ensures that the spatial position of the source is in a better orientation with a small number of parts, thus eliminating the need for complex adjustment mechanisms and processes.

[0029] Reference Figure 2 As a preferred technical solution in this embodiment, the source mounting structure further includes a support base 30. The support base 30 is located at the bottom of the side of the source 50 away from the mounting plate 20. The support base is used to support the front end of the source and can alleviate the deformation of the bracket caused by the weight of the source. At the same time, the lower part of the support base is provided with a screw to adjust the height. By adjusting its height, the source can be made to just contact the surface of the support base. The material of the support base can be polyurethane.

[0030] Reference Figure 2 In some embodiments, the bracket 10 includes a back panel 120, side panels 130, a front panel 140, and an inclined panel 150. There are two side panels 130, symmetrically arranged in parallel on both sides of the back panel. The front panel 140 is positioned opposite the back panel, parallel to the back panel, and located on the side of the side panels. The inclined panel 150 is positioned on top of the back panel 120, side panels 130, and front panel 140. In use, the back panel, side panels, and front panel form the main frame structure of the bracket, and the inclined panel is then installed on top of this main frame structure, thus forming the bracket structure. It should be noted that the tilt angle of the inclined panel can be adjusted according to actual usage requirements; that is, the tilt angle of the inclined panel can be changed according to the required tilt angle of the radiation source.

[0031] Furthermore, the back panel 120, side panel 130, front panel 140 and oblique panel 150 are each provided with a number of perforated holes 160. It should be noted that there are multiple perforated holes, and their shapes can be rectangular, strip-shaped or circular, without much restriction.

[0032] Reference Figure 3 In some embodiments, the mounting plate 20 includes a horizontal plate 210 and a vertical plate 220. The horizontal plate 210 is disposed on the mounting inclined surface 110, and the vertical plate 220 is vertically fixed to the top of the horizontal plate. Specifically, in this embodiment, the vertical plate 220 and the horizontal plate 210 form an inverted T-shaped structure. It should also be noted that the vertical plate can be fixed to the horizontal plate by welding or other fixed connection methods to improve the stability of the mounting plate.

[0033] To further improve the stability of the mounting plate, the mounting plate 20 also includes multiple ribs 230. The ribs 230 are disposed between the top of the horizontal plate 210 and the side wall of the vertical plate 220. In this way, the horizontal plate, the vertical plate and the ribs form a triangular support structure to further improve the stability of the mounting plate.

[0034] In some embodiments, the adapter assembly includes a rotating seat 410, which is rotatably disposed on the side wall of the vertical plate 220. The end of the rotating seat away from the vertical plate is fixedly connected to the source 50. Thus, when it is necessary to rotate the source to cause the source to swing left and right, the source can be driven to move, and the source will then rotate relative to the vertical plate through the rotating seat to obtain a small range of left and right swing. In addition, in order to fix the source after the left and right swing is completed, a plurality of first mounting holes 221 that cooperate with the source 50 are provided on the vertical plate 220. It should be noted that the first mounting holes are milled immediately after the source swings, and then the source and the vertical plate are fixedly connected by bolts or other fasteners to achieve the purpose of fixing the source.

[0035] Furthermore, the horizontal plate 210 is provided with a second mounting hole 211 for fixing the horizontal plate to the top of the bracket 10. Specifically, in this embodiment, the number of the second mounting holes is two sets symmetrically arranged on both sides along the length direction of the horizontal plate, and each set has three holes. In use, the source is connected to the vertical plate. When the source needs to be horizontally twisted along the mounting slope of the bracket, the bracket can be rotated around the hole in the middle of one set of second mounting holes as the rotation center, and twisted in a small range along the center of the hole. After the twist is completed, the horizontal plate is fixed to the top of the mounting slope using bolts or other fasteners to achieve the purpose of adjusting the horizontal twist angle of the source.

[0036] This application also provides an X-ray imaging device, including the aforementioned source mounting structure. The source in the X-ray imaging device is mounted on the top of the bracket 10. The X-ray imaging device also includes a detector 60. The mounting slope and mounting plate in the mounting structure can be used to adjust the source tilt angle, left and right swing angle and horizontal torsion angle, respectively, so as to adjust the source to a better CT imaging position.

[0037] In addition, this application also provides a breast CT scanner, including the aforementioned radiation source mounting structure. The breast CT scanner can adaptively adjust the orientation of the radiation source using the aforementioned radiation source mounting structure to improve the convenience and accuracy of CT imaging.

[0038] In use, the back panel 120, side panel 130, front panel 140, and inclined panel 150 constitute the main structure of the bracket 10, which supports the radiation source 50. When the tilt angle of the radiation source 50 needs to be adjusted, the tilt angle of the inclined panel 150 can be changed to indirectly adjust the tilt position of the radiation source 50. When the left and right sway angle of the radiation source needs to be adjusted, the radiation source uses an adapter to deflect relative to the mounting plate 20 to adjust its own left and right sway angle. In addition, when the horizontal torsion angle of the radiation source needs to be adjusted, the mounting plate 20 can be moved, and the mounting plate rotates at a certain angle along the top of the mounting inclined surface 110, thereby causing the radiation source 50 connected to the mounting plate 20 to rotate horizontally. It should be noted that the radiation source tilt angle adjustment, left and right sway adjustment, and horizontal torsion adjustment in this application can be performed independently or in combination.

[0039] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
