Description

Technical Field

[0001] This utility model relates to the field of CT technology, and in particular to a rotor system for CT equipment and CT equipment. Background Technology

[0002] Computed tomography (CT) systems, also known as computed tomography systems, primarily utilize detectors to receive X-rays and form high-quality images to perform corresponding detection. Therefore, the installation position of the detectors directly affects the final detection results.

[0003] In existing technology, CT equipment includes a rotor, on which an X-ray source and a detector array are fixedly connected. The detectors are arranged according to the shape of the rotor and the actual detection requirements. To ensure that the detectors can effectively receive X-rays, the detector array needs to be distributed circumferentially around the rotor.

[0004] However, due to the limitations of the overall shape of the rotor, the installation position of the detector is not very accurate, resulting in poor X-ray reception and consequently poor detection accuracy. In order to improve the installation position accuracy of the detector on the rotor, the shape of the rotor needs to be machined with a higher level of precision, which increases the overall machining difficulty. Utility Model Content

[0005] The purpose of this invention is to provide a rotor system and CT equipment for CT devices, which solves the problem in the prior art that the rotor shape limits the installation position accuracy of the detector, resulting in a trade-off between improving detection accuracy and reducing manufacturing difficulty.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a rotor system for CT equipment, comprising:

[0008] The main body is used for fixed connection with the bearing rotor of the CT equipment, and the main body has an installation space.

[0009] A mounting bracket is disposed on the main body, and the mounting bracket has multiple mounting positions for mounting detectors capable of receiving X-rays;

[0010] And a radiation source assembly, disposed on the main body and disposed opposite to the mounting bracket for generating X-rays that irradiate the detector.

[0011] Optionally, the mounting bracket includes:

[0012] A mounting plate is disposed in the mounting space;

[0013] The mounting part is disposed on the mounting plate. The mounting part has a plurality of mounting platforms protruding on the side away from the radiation source assembly. Each mounting platform has a mounting surface on the side away from the radiation source assembly as the mounting position.

[0014] Optionally, the mounting portion is arc-shaped, and a plurality of mounting platforms are distributed sequentially along the extension direction of the mounting portion.

[0015] Optionally, the mounting portion is strip-shaped and has a first portion and a second portion, the first portion being directly opposite the radiation source assembly, and the thickness of the mounting portion decreasing from the second portion to the first portion.

[0016] Optionally, multiple mounting plates are arranged around the circumference of the main body, and the multiple mounting plates are spliced ​​together sequentially.

[0017] Optionally, two mounting brackets are arranged opposite each other, and the two ends of the detector are respectively connected to two mounting positions opposite the mounting brackets.

[0018] Optionally, the outer side wall of the main body has a fixing surface, and an irradiation hole is formed through the fixing surface. The radiation source assembly is disposed on the fixing surface and the emitting end corresponds to the irradiation hole.

[0019] Optionally, the rotor system for the CT scanner further includes:

[0020] A mounting plate is disposed on the main body and is used to install electronic control components or cooling components.

[0021] Secondly, this utility model provides a CT device, which includes:

[0022] Support base;

[0023] The bearing is disposed within the support base;

[0024] The rotor system for a CT device as described in any one of the first aspects is disposed within the bearing;

[0025] And a drive assembly, disposed on the support and connected to the bearing.

[0026] Optionally, the driving component includes:

[0027] A driving component is disposed on the support base;

[0028] In addition, a transmission belt, one end of which is fitted onto the output end of the drive unit, and the other end of which is fitted onto the rotor of the bearing.

[0029] The beneficial effects of this utility model are:

[0030] Firstly, by setting a mounting frame on the main body and forming multiple mounting positions on the frame, a detector can be installed at each position. The mounting frame is designed to meet the requirements of installation space and detector installation position, ensuring that each mounting position can be precisely positioned at the designated location. This ensures that the angle of the detector installed at that position and the distance from the X-ray source assembly are optimal, allowing the detector to receive X-rays generated by the X-ray source assembly with high quality during the rotation of the main body. Therefore, when using this rotor system for CT equipment, the mounting frame can be designed according to actual needs, forming multiple mounting positions for detectors within the main body. This reduces the limitations imposed by the shape of the main body on detector installation, improving the accuracy of detector installation position and enabling high-quality X-ray signal reception. Thus, when this rotor system is used in CT equipment, it effectively improves detection accuracy. Furthermore, the main body does not require high-level precision machining, and the mounting frame can be manufactured using conventional machining designs, such as using a four-axis machine tool, without the need for special cutting tools, effectively reducing machining difficulty.

[0031] Secondly, during operation, the CT equipment rotates by driving the rotor of the bearing via a drive component, thereby rotating the main body of the rotor system. During this rotation, the detector receives X-ray signals generated by the radiation source component and transmits them to a computer for data processing, ultimately forming a CT image. Because the detector in this rotor system has high installation precision, it can effectively receive signals with high quality according to the detection requirements, resulting in high-quality CT images that meet the detection needs.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] This utility model discloses a rotor system for CT equipment and a CT equipment.

[0045] Reference Figures 1 to 4 The rotor system for CT equipment includes a main body 1, a mounting frame 2, and a radiation source assembly 3. The main body 1 is used to fix the bearing rotor of the CT equipment, and the main body 1 has an installation space; the mounting frame 2 is disposed on the main body 1, and the mounting frame 2 has multiple mounting positions for mounting detectors 4 that can receive X-rays; the radiation source assembly 3 is disposed on the main body 1 and is disposed opposite to the mounting frame 2 to generate X-rays that irradiate the detectors 4.

[0046] Specifically, the main body 1 is ring-shaped, with an installation space extending through its sidewall. A mounting frame 2 is installed on the sidewall of the installation space. The mounting frame 2 can be ring-shaped or elongated, and can be formed by splicing multiple segments. There can be one mounting frame 2 or multiple frames arranged around it. The mounting frame 2 is detachably connected to the main body 1, which can be achieved through bolts or snap-fit ​​connections. The shape of the mounting frame 2 can be adapted to the shape of the installation space. Multiple installation positions are arranged on the mounting frame 2 according to the actual dimensions, each for installing one detector 4. The specific model of the detector 4 can be selected based on existing technology. The X-ray source assembly 3 is fixed to the outer sidewall of the main body 1, and is located on the upper and lower sides of the main body 1, respectively, forming a relative arrangement with the mounting frame 2.

[0047] By setting a mounting bracket 2 on the main body 1 and forming multiple mounting positions on the mounting bracket 2, a detector 4 can be installed at each mounting position. The mounting bracket 2 can be designed according to the installation space and the installation position requirements of the detector 4, ensuring that each mounting position can be accurately set in the designated position, and ensuring that the angle of the detector 4 installed at that position and the distance from the X-ray source assembly 3 are kept at the optimal level. This allows the detector 4 to effectively receive the X-rays generated by the X-ray source assembly 3 during the rotation of the main body 1. In this way, when using the rotor system of this CT equipment, the mounting bracket 2 can be designed according to actual needs, thereby forming multiple mounting positions for the detector 4 within the main body 1. This reduces the restriction on the installation of the detector 4 by the shape of the main body 1, which not only improves the installation position accuracy of the detector 4, but also enables the detector 4 to receive X-ray signals with high quality. Therefore, when this rotor system is used in CT equipment, it can effectively improve the detection accuracy. At the same time, the main body 1 does not require high-level precision machining, and the mounting bracket 2 can also be completed through conventional machining design, such as using a four-axis machine tool. No special tools are required, thus effectively reducing the machining difficulty.

[0048] Optionally, the mounting bracket 2 includes a mounting plate 21 and a mounting section 22. The mounting plate 21 is disposed in the mounting space; the mounting section 22 is disposed on the mounting plate 21, and a plurality of mounting platforms 23 are provided on the side of the mounting section 22 away from the X-ray source assembly 3. Each mounting platform 23 is provided with a mounting surface 231 on the side away from the X-ray source assembly 3 as a mounting position.

[0049] Specifically, the mounting plate 21 can be strip-shaped, circumferentially arranged around the main body 1, with its inner sidewall being arc-shaped and its outer sidewall being segmented. One side of the mounting plate 21 is attached to the side of the mounting space, and the two can be detachably connected by bolts or clips to facilitate adjustment of the arrangement of multiple mounting plates as needed. The other side of the mounting plate 21 is provided with a mounting part 22, which extends and bends along the circumference of the main body 1. It can be integral with the mounting plate 21 or fixed together by adhesive or welding. A mounting platform 23 protrudes from the side of the mounting part 22 away from the radiation source. Multiple mounting platforms 23 can be evenly distributed along the length of the mounting part 22 or evenly distributed along the circumference of the main body 1, and the resulting mounting surfaces 231 can all face the radiation source. In this embodiment, the mounting plate 21 and the mounting part 22 are integrally structured, and multiple stepped mounting platforms 23 can be formed on the side of the mounting plate 21 by cutting.

[0050] The mounting plate 21 allows for a surface-to-surface fit with the mounting space, providing space for threaded holes or snap-fit ​​structures. This ensures a stable and secure connection between the mounting bracket 2 and the main body 1, preventing the mounting bracket 2 from shifting during rotation of the main body 1. An integrally formed mounting section 22 on the mounting bracket 2 ensures a high connection strength. Multiple mounting platforms 23 within the mounting section 22 further refine the position of the mounting surface 231, ensuring each mounting position is precisely designed at its designated location, thereby effectively improving the installation position accuracy of the detector 4.

[0051] Optionally, the mounting section 22 is arc-shaped, and multiple mounting platforms 23 are distributed sequentially along the extension direction of the mounting section 22.

[0052] Specifically, the arc-shaped mounting part 22 allows multiple mounting platforms 23 to be arranged around the circumference of the main body 1, thereby allowing the mounting surface 231 of the mounting platform 23 to tilt accordingly, so that the detectors 4 at different positions on the main body 1 can all face the specified direction.

[0053] Optionally, the mounting portion 22 is strip-shaped and has a first portion and a second portion, the first portion being directly opposite the radiation source assembly 3, and the thickness of the mounting portion 22 decreasing from the second portion to the first portion.

[0054] Specifically, the first part and the radiation source assembly 3 are located on the upper and lower sides of the main body 1, respectively, while the two ends of the mounting plate 21 are located on both sides of the first part as the second part. The thickness of the mounting part 22 decreases from the second part to the first part, so that the opening angle of the mounting stage 23 gradually changes from the second part to the first part, so as to ensure that the mounting angle of the detector 4 and its distance from the radiation source assembly 3 are kept optimal at different mounting positions.

[0055] Optionally, two mounting brackets 2 are arranged opposite each other, and the two ends of the detector 4 are respectively connected to the two mounting positions of the opposite mounting brackets 2.

[0056] Specifically, the detector 4 is elongated, and its two ends are respectively attached to the mounting surfaces 231 of the two mounting platforms 23, and the two are fixedly connected together by bolts.

[0057] This allows the sides of detector 4 to fit against the two mounting surfaces 231, and both ends of detector 4 are fixed to the mounting surfaces 231 by bolts or other fasteners, thereby effectively improving the installation stability of detector 4.

[0058] Optionally, multiple mounting plates 21 are arranged around the circumference of the main body 1, and the multiple mounting plates 21 are spliced ​​together in sequence.

[0059] Specifically, there are multiple mounting plates 21 that are spliced ​​together sequentially, so that the shape of each mounting plate 21 can be adjusted, allowing the entire mounting frame 2 to be designed entirely according to actual testing requirements. In this embodiment, two mounting plates 21 are provided, and the two mounting plates 21 form the first part of the mounting frame 2 at the splicing point, while the other end of the mounting plate 21 extends circumferentially along the main body 1 to form the second part.

[0060] Optionally, the outer wall of the main body 1 has a fixing surface 11, through which an irradiation hole 12 is opened, and the radiation source assembly 3 is disposed on the fixing surface 11 with its emitting end corresponding to the irradiation hole 12.

[0061] Specifically, a fixing surface 11 is provided on the outer wall of the main body 1, which is directly opposite to the first part. A through hole is provided in the middle of the fixing surface 11 as an irradiation hole 12. The radiation source assembly 3 is disposed on the fixing surface 11 and can be fixed by multiple bolts. The emitting end of the radiation source is directly opposite the irradiation hole 12.

[0062] By setting a fixing surface 11 on the outer side wall of the main body 1, the X-ray source assembly 3 can be directly fixed to the outer side wall of the main body 1. This not only eliminates the need for additional fixing structures to fix the X-ray source assembly 3, effectively reducing the complexity of the overall structure, but also ensures that the positions of the X-ray source assembly 3 and multiple detectors 4 remain corresponding, improving the installation position accuracy of both.

[0063] Optionally, the rotor system for the CT equipment also includes a mounting plate 13. The mounting plate 13 is disposed on the main body 1 and is used to mount the electrical control assembly 5 or the cooling assembly 6.

[0064] Specifically, a fixing plate 13 is respectively installed on the main body 1 at the hollow positions on both sides of the fixing surface 11. The fixing plate 13 can fill the hollow structure of the main body 1. The fixing plate 13 can be integral with the main body 1, or it can be fixedly connected by welding or bolts. An electronic control component 5 is installed on one fixing plate 13, and a cooling component 6 is installed on the other fixing plate 13, so that both the electronic control component 5 and the cooling component 6 are installed on the main body 1, thereby effectively improving the integration level of the rotor system. The specific electronic control component 5, cooling component 6, and radiation source component 3 can all be selected with reference to the prior art. This is not a utility model point of this solution, and will not be described in detail here.

[0065] Reference Figure 5 and Figure 6 The CT device includes a support base 7, a bearing 8, a drive assembly 9, and a rotor system for the CT device as described in the above embodiment. The bearing 8 is disposed within the support base 7; the rotor system for the CT device is disposed within the bearing 8; and the drive assembly 9 is disposed within the support base 7 and connected to the bearing 8.

[0066] Specifically, the support base 7 is hollow in the middle to accommodate the stator of the bearing 8, and the main body 1 of the CT equipment rotor system is fixedly connected to the rotor of the bearing 8. The drive assembly 9 includes a drive component 91 and a transmission belt 92. The drive component 91 is disposed on the support base 7, and can be a servo motor or an electric cylinder, etc., which is not limited in this invention. One end of the transmission belt 92 is sleeved on the output end of the drive component 91, and the other end is sleeved on the rotor of the bearing 8.

[0067] When in use, this CT equipment drives the rotor of the bearing 8 to rotate via the drive component 9, thereby driving the main body 1 of the rotor system to rotate. During rotation, the detector 4 receives the X-ray signal generated by the X-ray source component 3 and transmits it to the computer for data processing, ultimately forming a CT image. Because the detector 4 in this rotor system has high installation accuracy, it can effectively receive signals with high quality according to the detection requirements, thus ensuring that the final CT image has high quality and meets the detection requirements.
