Description

Technical Field

[0001] This utility model relates to the field of CT imaging technology, and in particular to a CT imaging probe assembly. Background Technology

[0002] The CT imaging probe is a key component of a computed tomography (CT) system. It is used to receive X-rays passing through the object being scanned and convert them into electronic signals. The signal data received by the probe reflects the attenuation characteristics of the X-rays in the object, providing the basis for reconstructing tomographic images. The accuracy and sensitivity of the probe directly affect the image quality. It is widely used in medical diagnosis, industrial non-destructive testing, and scientific research to generate high-resolution tomographic images.

[0003] In existing technologies, CT imaging probes are generally fixed in an array on a ring frame. However, the CT imaging probe cannot be fine-tuned along the radial length of the ring frame, which may lead to insufficient detector sensitivity in some scanning areas, affecting imaging resolution and detail capture capabilities. In addition, in specific scenarios, such as when a larger field of view or higher density acquisition is required, the fixed radial detector layout may not meet the requirements, resulting in incomplete image coverage. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in the prior art, CT imaging probes are generally fixed in an array on a ring frame. However, the CT imaging probe cannot be finely adjusted along the radial length of the ring frame, which may lead to insufficient detector sensitivity in some scanning areas, affecting imaging resolution and detail capture capabilities. In addition, in specific scenarios, such as when a larger field of view or higher density acquisition is required, the fixed radial detector layout may not meet the requirements, resulting in incomplete image coverage. Therefore, this invention proposes a CT imaging probe assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A CT imaging probe assembly includes a fixed ring frame and an imaging probe. A connecting ring is fixedly disposed on the outer wall of the fixed ring frame, and fixed grooves are equidistantly formed on the outer wall of the fixed ring frame. A bottom frame is movably inserted into the fixed ring frame within the fixed grooves. A horizontal column is rotatably connected to the side of the bottom frame, and a fixed frame is fixedly connected to the side of the horizontal column. An imaging probe is movably inserted into the cavity of the fixed frame. A radial adjustment structure is provided on the side of the fixed frame to adjust the radial distance of the imaging probe along the fixed ring frame. A vertical adjustment structure is provided on the top of the bottom frame to adjust the tilt angle of the imaging probe relative to a vertical plane.

[0007] Optionally, the connecting ring is symmetrically fixed with fixing ears on both sides, and the fixing ears are provided with holes at equal intervals along the vertical direction.

[0008] Optionally, the radial adjustment structure includes a locking bolt and a vertical U-groove. The fixing frame has a vertical U-groove along the vertical direction. The locking bolt passes through the vertical U-groove and is screwed into the side of the imaging probe housing. The width of the locking bolt head is greater than the width of the vertical U-groove.

[0009] Optionally, the vertical adjustment structure includes a damping column, a common rod, and an intermediate screw. The tail of the intermediate screw is threaded into the top plate, and the head of the intermediate screw is rotatably connected to the middle position of the top of the common rod.

[0010] Optionally, damping columns are fixedly installed at the bottom of both ends of the common rod, and the bottom ends of the two damping columns are in contact with the top of the horizontal column.

[0011] Optionally, a barb is fixedly provided at the top edge of the fixed frame, and a wire harness groove is provided on the outer wall of the barb.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model indirectly connects the fixed ring frame and the imaging probe through a fixed frame and a bottom frame. The fixed frame has a radial adjustment structure on its side. The radial adjustment structure can adjust the radial distance of the imaging probe along the fixed ring frame within a certain range. This solves to some extent the problem in the prior art where CT imaging probes are generally fixed in an array on a ring frame, but the radial length of the CT imaging probe along the ring frame cannot be finely adjusted, which may lead to insufficient detector sensitivity in some scanning areas, affecting imaging resolution and detail capture capability.

[0014] 2. A vertical adjustment structure is provided between the fixed frame and the bottom frame of this utility model. The vertical adjustment structure can adjust the tilt angle between the imaging probe and the vertical plane, so that the imaging probe can be better aligned with the target area, optimize the imaging angle, reduce imaging distortion, and improve the resolution and accuracy of the scanning results.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A CT imaging probe assembly includes a fixed ring frame 3 and an imaging probe 10. A connecting ring 2 is fixedly disposed on the outer wall of the fixed ring frame 3. Fixed grooves 21 are equidistantly opened on the outer wall of the fixed ring frame 3. A bottom frame 11 is movably inserted into the fixed ring frame 3 within the fixed grooves 21. A horizontal column 8 is rotatably connected to the side of the bottom frame 11. A fixed frame 12 is fixedly connected to the side of the horizontal column 8. An imaging probe 10 is movably inserted into the cavity of the fixed frame 12. The imaging probe 10 is an essential structural component in existing CT scanners, therefore its detailed structure is not disclosed in this application.

[0021] The fixed frame 12 has a radial adjustment structure on its side for adjusting the radial distance of the imaging probe 10 along the fixed ring frame 3. The bottom frame 11 has a vertical adjustment structure on its top for adjusting the tilt angle between the imaging probe 10 and the vertical plane. The connecting ring 2 has fixed ears 1 symmetrically fixed on both sides. The fixed ears 1 have holes equidistantly opened in the vertical direction. The entire fixed ring frame 3 can be fixed to the frame by passing bolts through the holes on the fixed ears 1.

[0022] The radial adjustment structure includes a locking bolt 9 and a vertical U-groove 13. The fixing frame 12 has a vertical U-groove 13 in the vertical direction. The locking bolt 9 passes through the vertical U-groove 13 and is screwed into the side of the imaging probe 10 housing. The width of the head of the locking bolt 9 is greater than the width of the vertical U-groove 13. When the locking bolt 9 is in different positions inside the vertical U-groove 13, the radial distance of the imaging probe 10 is different.

[0023] The vertical adjustment structure includes a damping column 7, a common rod 6, and an intermediate screw 4. The tail of the intermediate screw 4 is screwed into the top plate 5, and the head of the intermediate screw 4 is rotatably connected to the top middle position of the common rod 6. Damping columns 7 are fixedly installed at the bottom of both ends of the common rod 6. The bottom ends of the two damping columns 7 are in contact with the top of the horizontal column 8. A barb rod 14 is fixedly installed at the top edge of the fixed frame 12. A cable tray 15 is opened on the outer wall of the barb rod 14 for leading the signal line of the imaging probe 10 out from the inside of the fixed frame 12 and the bottom frame 11.

[0024] The specific implementation steps and principles of this utility model are as follows:

[0025] When it is necessary to adjust the radial distance and the vertical inclination angle of a specific imaging probe 10, loosen the locking bolt 9 and the intermediate screw 4 in sequence. At this time, the imaging probe 10 can be pulled out of the fixed frame 12 by an appropriate distance. The locking bolt 9 moves along the vertical U-groove 13. At the same time, the damping column 7 no longer applies damping to the horizontal column 8. After rotating the imaging probe 10 to an appropriate distance, tighten the intermediate screw 4 again. The intermediate screw 4 applies damping to the rotation of the horizontal column 8 through the common rod 6 and the damping column 7, thus fixing the imaging probe 10 at a specific inclination angle.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
