Description
Technical Field
[0001] This application belongs to the field of medical instrument technology, and specifically relates to X-ray-based medical imaging detection devices. Background Technology
[0002] Explanation of the name:
[0003] CT (Computed Tomography) is a medical imaging technique. It uses X-ray beams to perform tomographic scans of the human body and then uses computer processing to produce detailed images of the body's internal structures.
[0004] DR: Digital Radiography is short for Digital X-ray imaging system. In this application, DR refers to medical DR. Medical DR is a relatively advanced examination method in radiology and can be used for the diagnosis, differential diagnosis and prognosis assessment of diseases of multiple organ systems in clinical practice.
[0005] In hospitals, different detection equipment is used in different scenarios; for example, DR equipment is used to take pictures of the chest, and high-resolution CT equipment is used to take pictures of blood vessels in the head.
[0006] In existing technologies, CT equipment is typically equipped with a matching examination bed. Traditional spiral CT requires horizontal movement to perform CT imaging. This necessitates a complex spiral mechanism, resulting in a complex and costly mechanical system.
[0007] In existing technologies, CT equipment includes medical radiological detection devices with cone-beam X-ray sources. During the detection process, no screw-in mechanism is required. To obtain image sections from different locations, the internal structure of the main unit needs a highly precise gear structure to control the rotation angle of key components. However, smooth rotation is required, necessitating high coaxiality of the rotating parts. Traditionally, large-diameter precision gear rings are used as drive components, which are not only expensive but also cumbersome to maintain, resulting in high costs.
[0008] Designing a CT or DR device with a simpler overall structure, easier operation, and lower cost and maintenance is a key technical challenge. This is especially true in applications such as veterinary hospitals, where cost is a major concern, and simple structure, easy operation, and convenient maintenance are also essential. Therefore, designing a medical radiological detection device suitable for these applications is a crucial problem to be solved. Summary of the Invention
[0009] In this application, the inventor proposes a medical radiation detection device with a cone-beam X-ray source. A rotating track is set up to drive the emission source assembly and the flat plate detection assembly to rotate. The emission source assembly and the flat plate detection assembly are located on one side of the rotating ring assembly and are not located inside the rotating support assembly. The device has a simple structure, is easy to operate, and is convenient to maintain.
[0010] The solution to the above-mentioned technical problems is a medical radiological detection device with a cone-beam X-ray source, comprising: a rotating assembly and a rotating support assembly; the rotating assembly includes a rotating ring assembly, an emission source assembly, and a flat panel detector assembly; the rotating ring assembly is a hollow ring structure with a rotating track in the middle; the emission source assembly and the flat panel detector assembly are mounted face-to-face on one side of the rotating ring assembly; the rotating ring assembly is used to drive the emission source assembly and the flat panel detector assembly to rotate around the central axis along the rotating track to capture 2D medical images at different angles; the rotating support assembly includes a support leg assembly, a hollow support assembly, and at least three rotating support devices; the support leg assembly is used to support the hollow support assembly; the hollow support assembly includes a hollow part for accommodating the rotating ring assembly; the rotating support device includes a rotating drive device for driving the rotating assembly to rotate around the central axis; the emission assembly includes an emission source; the emission source is a cone-beam X-ray source.
[0011] Alternatively, the main body of the rotating track in the rotating ring assembly may be located inside the hollow part of the hollow support assembly; the hollow part of the hollow support assembly and the rotating track in the rotating ring assembly may be coaxially arranged; and the rotating drive device may be installed inside the rotating track, so that the rotating track is fitted into the hollow part of the hollow support assembly.
[0012] Alternatively, the rotating ring assembly may also include a first rotating ring ear and a second rotating ring ear, with a rotating track disposed between the first rotating ring ear and the second rotating ring ear; the emission source assembly and the flat plate detection assembly are fixed face-to-face on one side of the second rotating ring ear; the first rotating ring ear and the second rotating ring ear are respectively fixedly connected to the main body of the hollow support assembly.
[0013] Alternatively, the aforementioned rotation drive device may include a rotation bearing and a bearing support; the rotation bearing is mounted on the bearing support, and the bearing support is fixed inside the hollow part of the hollow support assembly; the rotation bearing is used to support the rotation track, and the rotation ring assembly can rotate around the central axis under the support of the rotation bearing.
[0014] Alternatively, at least one rotating support device may include a drive motor, which drives the rotating bearing to rotate.
[0015] It can be that at least one rotating support device includes a drive motor and a friction wheel; the drive motor is a stepper motor, and the shaft of the stepper motor is connected to the friction wheel; the friction wheel is in contact with the rotating bearing, and the friction wheel is used to drive the rotating bearing to rotate.
[0016] The hollow part of the hollow support component can be a polygonal cavity; or the hollow support component can be circular in shape.
[0017] Yes, the polygonal cavity mentioned above can be a hexagonal cavity.
[0018] The hollow support assembly may be hexagonal in shape; it may also include a display, which is mounted on the outside of one side of the hexagon.
[0019] It can include a rotary encoder, which detects the position of the rotating component relative to the rotating support component; and constructs a 3D medical image based on the 2D medical images at different positions.

The handle is used to pull the rotating ring component to rotate, thereby driving the emission source component and the flat panel detection component to rotate and acquire 2D medical images at different positions.
[0021] It could be a movable detection bed assembly; the detection bed assembly is used to carry the object to be detected, and moving the detection bed assembly so that the imaging target position of the object to be detected is located between the emission source assembly and the flat plate detection assembly.

Capture 2D medical images from different angles; the rotating support assembly 200 includes a supporting leg assembly 210, a hollow support assembly 220, and at least three rotating support devices 500; the supporting leg assembly 210 supports the hollow support assembly 220; the hollow support assembly 220 includes a hollow portion for accommodating the rotating ring assembly 110; the rotating support device 500 includes a rotating drive device 510 for driving the rotating assembly 100 to rotate around a central axis 800; the emitting assembly includes an emitting source; the emitting source is a cone-beam X-ray source.
[0044] The rotating ring assembly 110 drives the transmitter assembly 120 and the flat panel detector assembly 130 to rotate around the central axis 800 along the rotating track 115, capturing 2D medical images from different angles. Compared to a rack and pinion structure, the track has lower manufacturing costs and is easier to maintain. Power components, compared to ordinary components, are more prone to wear and tear and have a shorter lifespan; therefore, their manufacturing and maintenance cycles and costs should be considered from the initial design stage. The rotation of the track structure and the rotating drive device 510, working in conjunction, ensures accurate rotational positioning while reducing the manufacturing cost and complexity of key components. Accurate relative positioning is guaranteed as long as the components are on the track.
[0045] like Figures 1 to 4The main body of the rotating track 115 in the rotating ring assembly 110 is disposed within the hollow portion of the hollow support assembly 220; the hollow portion of the hollow support assembly 220 and the rotating track 115 in the rotating ring assembly 110 are coaxially arranged; the rotation drive device 510 is installed inside the rotating track 115, so that the rotating track 115 is fitted into the hollow portion of the hollow support assembly 220.

The rotation direction of the moving parts on the main body of the rotating track 115 is orthogonal to the direction of the rotating ring through hole 111.
[0046] The rotation drive device 510 is installed inside the rotation track 115, so that the rotation track 115 fits into the hollow part of the hollow support assembly 220. This structure ensures the accuracy of the position of the rotation track 115, reduces the influence of the inertia of the moving parts on the track as a whole, and makes it more stable.
[0047] like Figures 1 to 4 The rotating ring assembly 110 also includes a first rotating ring ear 116 and a second rotating ring ear 117, with a rotating track 115 disposed between the first rotating ring ear 116 and the second rotating ring ear 117.

The ears of the first rotating ring ear 116 and the second rotating ring ear 117 extend to both sides relative to the rotating track 115, and the extended ears are used for fixed connection with the main body of the hollow support assembly 220.
[0048] The first ear 116 and the second ear 117 of the rotating ring are fixedly connected to the main body of the hollow support assembly 220, which further increases the overall stability of the track.

[0050] The rotary bearing 511 supports the rotary track 115, and the rotary ring assembly 110, supported by the rotary bearing 511, can rotate around the central axis 800. This rotating structure is more flexible and facilitates electrical and manual position adjustment.
[0051] In some embodiments, at least one rotating support device 500 includes a drive motor 513 that drives the rotating bearing 511 to rotate.
[0052] like Figures 5 to 7 In some embodiments, at least one rotating support device 500 includes a drive motor 513 and a friction wheel 515; the drive motor 513 is a stepper motor, and the shaft of the stepper motor is connected to the friction wheel 515; the friction wheel 515 contacts a rotating bearing 511, and the friction wheel 515 is used to drive the rotating bearing 511 to rotate. The rotational drive provided by the stepper motor and the friction wheel 515 is more stable.
[0053] like Figure 6 In some embodiments, the number of rotating support devices 500 is 6, and the number of rotating support devices 500 can be set according to the rotation requirements.
[0054] like Figures 5 to 7 In some embodiments, the hollow portion of the hollow support assembly 220 is a polygonal cavity. This polygonal cavity is a hexagonal cavity. For example... Figure 9 and Figure 11 In some embodiments, a display 270 is also included, which is mounted on the outside of one side of the hexagon.
[0055] like Figure 8 In some embodiments, the hollow support component 220 described above is circular in shape.
[0056] In some embodiments, a rotary encoder is included, which detects the position of the rotation of the rotation component 100 relative to the rotation support component 200; and a 3D medical image is constructed based on the 2D medical images at different positions.
[0057] like Figure 10 and Figure 11 In some embodiments, the rotating assembly 100 includes a handle 170, which is mechanically connected to the rotating ring assembly 110. The handle 170 is used to pull the rotating ring assembly 110 to rotate, thereby driving the emission source assembly 120 and the flat panel detection assembly 130 to rotate and acquire 2D medical images at different positions.
