Description

Technical Field

[0001] This utility model relates to the field of data transmission technology, specifically to a non-contact rotating system and a rotating CT system based on millimeter-wave communication. Background Technology

[0002] In large rotating systems, such as medical CT scanners, CT imaging data acquired on the rotating components needs to be transmitted to the fixed components for further processing. Currently, most large rotating systems use slip ring or optical module solutions for data transmission. The following example illustrates this using the most common large rotating system, the "medical rotating CT system": Figure 1 The rotating CT system shown uses a slip ring structure. The four wires on the left side are connected to four metal rings on the flange and rotate together with the flange. The four wires on the right side are connected to the four red brushes shown in the diagram and remain stationary along with the brushes. The four wires on the flange establish corresponding connections with the four signal lines on the brushes. The rotating components in the medical rotating CT system transmit the acquired CT imaging data through... Figure 1 The slip ring structure transmits data from four wires on the flange to four signal lines on the brush, thus enabling data transmission.

[0003] Rotating CT systems, such as medical rotating CT systems, typically generate hundreds of gigabytes of data per CT scan. Therefore, rotating systems often have very high requirements for data transmission rates. However, slip ring solutions can only support data transmission rates below 1 Gbps; higher rates suffer from signal quality degradation and severe bit errors due to contact issues with the spring contacts. While optical modules can support higher data transmission rates, their complex optical path design is costly, susceptible to dust contamination, and this technology is monopolized by foreign companies.

[0004] Therefore, it is necessary to provide a data transmission scheme for rotating systems that can meet the requirements of high-speed signal transmission, ensure high stability of signal transmission quality, and also have the advantages of simple structure and low cost. Utility Model Content

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] The non-contact rotating system and rotating CT system based on millimeter-wave communication provided by this utility model enable high-speed, continuous, and stable transmission of large-capacity data between the rotating and fixed components using millimeter-wave wireless communication technology; it also has the advantages of simple design and low cost.

[0040] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] Millimeter-wave communication technology boasts advantages such as high bandwidth, high transmission rate, low latency, strong directionality, miniaturization, and integration. In particular, its millimeter-wave frequency band provides extremely high bandwidth, easily achieving transmission rates exceeding 1Gbps, making it especially suitable for applications requiring high bandwidth transmission, such as those handling large-capacity and high-fidelity data.

[0043] Please see Figure 2 , Figure 2 This is a schematic diagram of a non-contact rotating system based on millimeter-wave communication, provided as an embodiment of the present invention.

[0044] This utility model embodiment provides a non-contact rotation system based on millimeter-wave communication, such as... Figure 2 As shown, it includes a fixing component 10, a rotating component 20, and a millimeter-wave communication component 30; the signal from the rotating component 20 can be transmitted to the fixing component 10 at high speed and stably through the millimeter-wave communication component 30 in a non-contact wireless communication manner for subsequent processing.

[0045] The millimeter-wave communication component 30 includes multiple millimeter-wave transmitting modules 31 and one millimeter-wave receiving module 32.

[0046] The fastener 10 is typically connected to the equipment base and remains fixed in place.

[0047] The rotating component 20 rotates relative to the fixed component around a fixed axis.

[0048] The millimeter-wave transmitting module 31, as a wireless radio frequency transmitting component, is used to convert the data collected on the rotating part into millimeter-wave wireless signals and transmit them.

[0049] The millimeter-wave receiving module 32, as a wireless radio frequency receiving component, is used to receive the millimeter-wave wireless signal transmitted by the millimeter-wave transmitting module 31 and convert it into a corresponding logic signal. The form of the logic signal is not limited; it can be a single-ended signal or a differential signal.

[0050] like Figure 2 As shown, in this embodiment, the rotating component 20 is rotatably disposed on one side of the fixed component 10, with a preset distance between them to maintain a non-contact state. The rotating component 20 can be an annular or arc-shaped structure; of course, depending on different requirements, the rotating component 20 can also be an irregular shape, such as a triangle or rectangle. Here, it is preferred that the rotating component 20 is an annular or arc-shaped structure, with its outer circumferential surface being a circular surface, that is, the outermost outermost part is circular. The structure of the fixed component 10 is not limited here, and it can be any shape that conforms to maintaining non-contact with the rotating component during rotation and being able to receive millimeter-wave signals at any time.

[0051] The millimeter-wave receiving module 32 in the millimeter-wave communication component 30 is fixedly mounted on the fixing member 10, and the millimeter-wave signal receiving direction of the millimeter-wave receiving module 32 corresponds to the rotating member 20, specifically to the millimeter-wave radiation direction of a millimeter-wave transmitting module 31 on the rotating member 20.

[0052] The millimeter-wave communication component 30 contains a plurality of millimeter-wave transmitting modules 31 arranged circumferentially along the rotating member 20. The circumferential direction refers to the circumferential orientation of the rotating member 20, which in this embodiment corresponds to the rotation direction of the rotating member 20; the circumferential arrangement means that the modules are positioned on the rotating member 20 near its edge / boundary along the rotation direction of the rotating member 20. For example, Figure 2 As shown, multiple millimeter-wave transmitting modules 31 are arranged around the outer circumferential surface 21 of the rotating component 20. In particular, there is an overlap between the millimeter-wave signal radiation ranges of two adjacent millimeter-wave transmitting modules 31 on the rotating component 20.

[0053] In this embodiment, the millimeter-wave communication component 30 is arranged to ensure that when the plurality of millimeter-wave transmitting modules 31 rotate synchronously with the rotating component 20, the millimeter-wave receiving module 32 on the fixing component 10 can receive the millimeter-wave signal emitted by at least one millimeter-wave transmitting module 31 at any time.

[0054] It is understood that when the rotating component 20 rotates, the millimeter-wave transmitting module 31 on the rotating component 2 and the millimeter-wave receiving module 32 on the fixed component 10 will undergo relative motion. In this embodiment, based on the layout of the millimeter-wave communication component 30, it is possible to ensure both the reliability and continuity of signal transmission during rotation.

[0055] Regarding the former, in this embodiment, as the rotating component 20 rotates, the millimeter-wave radiation range of each millimeter-wave transmitting module 31 will sequentially cover the millimeter-wave receiving module 30 on the fixed component 10. That is, when each millimeter-wave transmitting module 31 moves to correspond with the millimeter-wave receiving module 30, its millimeter-wave signal can be normally received by the millimeter-wave receiving module 30. This ensures the reliability of signal transmission during rotation. Here, this can be achieved by setting the distance between the fixed component 10 and the rotating component 20, and / or setting the distance between the millimeter-wave transmitting module 31 on the rotating component 20 and the millimeter-wave receiving module 32 on the fixed component 10, based on factors such as the structure of the rotating component 20, the configuration parameters of the millimeter-wave transmitting module 31 (including specific setting position, millimeter-wave radiation range, and millimeter-wave transmission angle), and the configuration parameters of the millimeter-wave receiving module 32 (specific setting position, millimeter-wave receiving area, and millimeter-wave receiving angle), etc.

[0056] To address the latter, in this embodiment, the overlap between the millimeter-wave signal radiation ranges of two adjacent millimeter-wave transmitting modules 31 is further defined to ensure the continuity of signal transmission during rotation. Specifically, as mentioned above, as the rotating component 20 rotates, the sender of the millimeter-wave signal received by the millimeter-wave receiving module 32 continuously changes. Here, by specifically setting the overlap between the millimeter-wave signal radiation ranges of every two millimeter-wave transmitting modules 31, all millimeter-wave transmitting modules 31 arranged around the rotating component 20 will construct a seamless millimeter-wave signal radiation area around the circumference of the rotating component 20. Here, seamless specifically means that as the rotating component rotates, the millimeter-wave signal radiation area sweeping across the receiving area of ​​the millimeter-wave receiving module 32 on the fixed component 10 is continuous and seamless. For example, Figure 2 The outer circumference of the rotating component 20 is circular, and the maximum millimeter-wave radiation angle of each millimeter-wave transmitting module is 6°. Therefore, a seamless millimeter-wave signal radiation area can be constructed around the periphery of the rotating component 20, corresponding to the receiving area of ​​the millimeter-wave receiving module 32 (i.e., the 6° region). Thus, when multiple millimeter-wave transmitting modules 31 rotate synchronously with the rotating component 20, the millimeter-wave receiving module 32 on the fixed component 10 can receive millimeter-wave signals at any time, i.e., it can receive millimeter-wave signals uninterruptedly; thereby achieving seamless switching of millimeter-wave signals during rotational motion, and ensuring the continuity of signal transmission during rotation.

[0057] Based on the above-mentioned millimeter-wave communication component configuration, the non-contact rotation system based on millimeter-wave communication provided in this embodiment can ensure that the signal on the rotating component 20 is transmitted completely and reliably to the fixed component 10 during rotation, while also ensuring the continuity of signal transmission during rotation.

[0058] The working principle of the non-contact rotation system based on millimeter-wave communication in this embodiment is as follows:

[0059] During the rotation of the rotating component, the data collected by the rotating component will be simultaneously transmitted in the form of millimeter-wave wireless signals through all millimeter-wave transmitting modules that rotate synchronously with the rotating component. The millimeter-wave receiving module located on the fixed component can receive the millimeter-wave signal emitted by at least one millimeter-wave transmitting module at any time during the rotation of the millimeter-wave transmitting module, so as to ensure that the signal emitted by the millimeter-wave transmitting module can be continuously and completely received by the millimeter-wave receiving module. Then, the millimeter-wave receiving module converts the received millimeter-wave signal into the corresponding logic signal and transmits it to the fixed component for subsequent processing.

[0060] In this embodiment, the single-channel transmission rate based on millimeter-wave wireless communication technology can reach up to 10Gbps, easily meeting the requirements for high-speed signal transmission between the rotating and fixed components. Based on a specific layout design of multiple millimeter-wave transmitting modules and one millimeter-wave receiving module, the millimeter-wave receiving module on the fixed component can receive millimeter-wave signals emitted by at least one transmitting module at any given time when multiple millimeter-wave transmitting modules rotate synchronously with the rotating component, thus ensuring the reliability and continuity of signal transmission. Therefore, the non-contact rotation system based on millimeter-wave communication provided in this embodiment can achieve high-capacity, high-speed, continuous, and stable non-contact signal transmission between the rotating and fixed components. It solves the signal quality problems caused by unstable contact and the lifespan problems caused by contact wear in sliding contact transmission schemes; compared to optical module transmission schemes, it reduces cost and design complexity.

[0061] It should be noted that the millimeter-wave communication component setup of multiple millimeter-wave transmitting modules + one millimeter-wave receiving module provided in this embodiment can greatly simplify the data processing of the millimeter-wave receiving module, the processing of multiple data streams, and the complexity of the device compared to the millimeter-wave communication component setup of multiple millimeter-wave transmitting modules + multiple millimeter-wave receiving modules.

[0062] Please see Figure 2 and Figure 3 These correspond to two different configuration methods of the millimeter-wave communication component in the non-contact rotating system based on millimeter-wave communication described in the embodiments of this utility model.

[0063] This embodiment is a further extension of the above embodiment, and provides two feasible configuration methods for the millimeter-wave communication component.

[0064] like Figure 2The diagram illustrates the first millimeter-wave communication component configuration provided in this embodiment. The outer circumferential surface of the rotating member 20 is circular, hereinafter referred to as the outer circumferential surface 21. The outer circumferential surface 21 of the rotating member 20 corresponds to one side of the fixing member 10; the millimeter-wave receiving module 32 is specifically disposed on the aforementioned side of the fixing member 10; the plurality of millimeter-wave transmitting modules 31 are arranged around the rotating member 20 on its outer circumferential surface 21.

[0065] like Figure 3 The diagram shows a second millimeter-wave communication component configuration provided in this embodiment. The rotating component 20 has an overall annular structure. The plurality of millimeter-wave transmitting modules 31 are arranged around the rotating component 20 on its side end face 22. Optionally, each millimeter-wave transmitting module 31 can be entirely located on the side end face 22 (not shown in the figure); alternatively, it can be arranged as follows: Figure 3 As shown, one end of each millimeter-wave transmitting module 31 is fixedly connected to the side end face 22 of the rotating component 20, and the other end is horizontally suspended on the side end face 22 of the rotating component 20 towards the center of the rotating component 20. The fixing component 10 has a suspended component 11 corresponding to the side end face 22. The millimeter-wave receiving module 32 is disposed on the side of the suspended component 11 corresponding to the side end face 22, specifically corresponding to one millimeter-wave transmitting module 31 on the side end face 22. It can be understood that the suspended component 11 on the fixing component 10 and the side end face 22 on the rotating component 20 are spaced at a predetermined distance to maintain a non-contact state. The suspended component 11 is used to house the millimeter-wave receiving module 32 and can ensure that the millimeter-wave receiving module 32 on the suspended component 11 can receive the millimeter-wave signal emitted by at least one millimeter-wave transmitting module 31 on the rotating component 20 at any time during the rotation of the rotating component 20. Preferably, the suspended component 11 is... Figure 3 The flat panel structure shown makes setup easier.

[0066] Optionally, whether the millimeter-wave transmitting modules 31 are set on the outer circumferential surface 21 or the side end face 22 of the rotating component 20, the spacing between the multiple millimeter-wave transmitting modules 31 can be set or they can be set seamlessly. The specific settings are based on the millimeter-wave radiation range and millimeter-wave transmission angle of each millimeter-wave transmitting module 31, on the premise of ensuring that there is overlap between the millimeter-wave signal radiation ranges of two adjacent millimeter-wave transmitting modules 31.

[0067] Both of the above-mentioned optional configurations for millimeter-wave communication components ensure that, when multiple millimeter-wave transmitting modules rotate synchronously with the rotating component, the millimeter-wave receiving module on the fixed component can receive the millimeter-wave signal emitted by at least one millimeter-wave transmitting module at any given time. The specific choice can be made flexibly according to different requirements.

[0068] Each millimeter-wave transmitting module in this embodiment includes a transmitting unit and a transmitting antenna connected thereto; each millimeter-wave receiving module includes a receiving unit and a receiving antenna connected thereto.

[0069] The transmitting unit is used to convert the data collected on the rotating part into millimeter-wave wireless signals; the transmitting antenna is used to transmit the millimeter-wave wireless signals output by the transmitting unit; the receiving antenna is used to receive the millimeter-wave wireless signals transmitted by the millimeter-wave transmitting module and convert them into corresponding electrical signals; the receiving unit is used to convert the electrical signals returned by the corresponding receiving antenna into logic signals.

[0070] Here, the transmitting unit and corresponding transmitting antenna in each millimeter-wave transmitting module can be an integrated structure, meaning they are designed together, and a single millimeter-wave transmitting module is considered a single structure. Alternatively, the transmitting unit and corresponding transmitting antenna can be separate structures, meaning they are designed as two independent functional components, and a single millimeter-wave transmitting module consists of an independent transmitting unit and an independent transmitting antenna. Regardless of the structural design, multiple transmitting antennas are arranged circumferentially along the rotating component, ensuring overlap between the millimeter-wave signal radiation ranges of adjacent transmitting antennas; simultaneously, the receiving antenna must be able to receive the millimeter-wave signal emitted by at least one receiving antenna at any given time. If a separate structure design is used, the transmitting unit can be located inside the rotating component as needed, and the receiving unit can be located inside the fixed component as needed.

[0071] In some specific implementations of this embodiment, such as Figure 2 and Figure 3 As shown, multiple millimeter-wave transmitting modules 31, rotating synchronously with the rotating component 20, will one by one face the millimeter-wave receiving module 32 on the fixed component 10. This "facing each other" means that the transmitting antenna on the millimeter-wave transmitting module 31 and the receiving antenna on the millimeter-wave receiving module 32 are directly opposite each other, with the center line of the millimeter-wave radiation area of ​​the transmitting antenna perpendicular to the receiving surface of the receiving antenna. This design ensures that the millimeter-wave radiation range of the transmitting antenna corresponds precisely to the receiving surface of the receiving antenna, thus improving the reliability of data transmission. Of course, a preset angle can also be set between the center line of the millimeter-wave radiation area of ​​the transmitting antenna and the receiving surface of the receiving antenna. Specifically, this design ensures that the millimeter-wave receiving module on the fixed component can receive the millimeter-wave signal emitted by at least one of the millimeter-wave transmitting modules at any given time when multiple millimeter-wave transmitting modules rotate synchronously with the rotating component, and then allows for flexible configuration based on different application scenarios.

[0072] In some other specific embodiments of this example, such as Figure 2As shown, the overall structure of a single millimeter-wave transmitting module 31 is arc-shaped. This structural design is more conducive to multiple millimeter-wave transmitting modules 31 being arranged in a surrounding layout on the outer circumferential surface 21 of the rotating component 20. As some preferred examples, the overall structure constructed from multiple arc-shaped millimeter-wave transmitting modules 31 may be a closed annular structure or an annular structure with cutouts (i.e., an arc-shaped structure), depending on factors such as the construction of the rotating component, the rotation method (e.g., periodic left-right rotation), and cost.

[0073] In some specific embodiments of this example, there is no gap between adjacent millimeter-wave transmitting modules. It is understood that, to ensure overlap between the millimeter-wave signal radiation ranges of two adjacent millimeter-wave transmitting modules, the multiple millimeter-wave transmitting modules 31 are preferably seamlessly connected. Of course, depending on the number of millimeter-wave transmitting modules, the range of the millimeter-wave radiation area, and the different transmission angles, a certain gap may be left between adjacent millimeter-wave transmitting modules, as long as it ultimately ensures that there is overlap between the millimeter-wave signal radiation ranges of two adjacent millimeter-wave transmitting modules, and that the millimeter-wave receiving module on the fixing member can continuously receive the millimeter-wave signals emitted by the rotating millimeter-wave transmitting module.

[0074] In some other specific embodiments of this example, such as Figure 4 As shown, each millimeter-wave receiving module 32 includes two receiving units 321 and two receiving antennas 322, with each receiving unit connected to one receiving antenna (not shown in the figure); each millimeter-wave transmitting module 31 includes two transmitting units 311 and two transmitting antennas 312, with each transmitting antenna connected to one transmitting antenna (not shown in the figure). As a preferred example, each receiving unit and its connected receiving antenna are implemented using a chip-scale packaged millimeter-wave receiving chip, and correspondingly, each transmitting antenna and its connected transmitting antenna are implemented using a chip-scale packaged millimeter-wave transmitting chip. That is, each millimeter-wave receiving module 32 integrates two millimeter-wave receiving chips (i.e., the overall structure shown by labels 321 and 322 in the figure), and has dual receiving functionality; each millimeter-wave transmitting module 31 integrates two millimeter-wave transmitting chips (i.e., the overall structure shown by labels 311 and 312 in the figure), and has dual transmitting functionality. Here, a millimeter-wave communication component consisting of a millimeter-wave receiving module with dual receiving function and a millimeter-wave transmitting module with dual transmitting function can significantly improve the ability to transmit and receive millimeter-wave signals compared to single receiving and single transmitting functions. At the same time, it can reduce the number of modules, improve integration, and simplify installation.

[0075] In some preferred embodiments of this example, such as Figure 2As shown, the maximum millimeter-wave signal coverage angle of each millimeter-wave transmitting module 31 is greater than 6°, and the size of each millimeter-wave transmitting module is 13ccm*2cm. Of course, the above parameters can be flexibly configured based on the number of millimeter-wave transmitting modules (specifically the number of transmitting antennas) and their millimeter-wave radiation range, assuming that there is overlap between the millimeter-wave signal radiation ranges of two adjacent millimeter-wave transmitting modules 31.

[0076] Please see Figure 5 , Figure 5 This is a schematic diagram of the overall structure of a non-contact rotating system provided in an embodiment of the present invention.

[0077] This embodiment is a further extension of any of the above embodiments, specifically refining the data processing part of the non-contact rotation system.

[0078] In this embodiment, the rotating component in the non-contact rotating system based on millimeter-wave communication specifically acquires radiation data, such as X-ray data. Correspondingly, such as... Figure 5 As shown, the non-contact rotation system based on millimeter-wave communication also includes a ray emitting unit 40 and a ray receiving unit 50; the ray emitting unit 40 and the ray receiving unit 50 are fixedly disposed at corresponding ends of the rotating component 20; the signal output end of the ray receiving unit 40 is connected to the millimeter-wave emitting module 31.

[0079] Here, the ray emitting unit 40 is used to emit specific electromagnetic waves, such as X-rays. These specific electromagnetic waves can be attenuated to varying degrees after passing through biological organisms, such as the human body.

[0080] The X-ray receiving unit 50 is used to receive the X-rays emitted by the X-ray emitting unit after they have passed through the biological organism, and to form corresponding image data of the biological internal structure. Each millimeter-wave transmitting module connected to the signal output terminal of the X-ray receiving unit converts the image data transmitted from the X-ray receiving unit into corresponding millimeter-wave wireless signals and transmits them simultaneously; the millimeter-wave receiving module of the fixing component converts the received millimeter-wave wireless signals back into the image data. Therefore, the non-contact rotation system based on millimeter-wave communication can transmit the biological internal structure image data acquired by the rotating component to the fixing component in a high-speed and stable manner.

[0081] In some other specific embodiments of this example, such as Figure 5As shown, the output of the millimeter-wave communication-based non-contact rotation system is connected to the terminal processor 60. That is, the output of the millimeter-wave receiving module 32 is connected to the terminal processor 60. The terminal processor 60 processes the signal output by the millimeter-wave communication-based non-contact rotation system, generates the final result, and displays it on the terminal. For example, if the signal output by the millimeter-wave communication-based non-contact rotation system is a biological internal structure image data stream signal, the terminal processor will generate a biological internal structure image and display it on the terminal.

[0082] It should be noted that the millimeter-wave communication component configuration of multiple millimeter-wave transmitting modules + one millimeter-wave receiving module provided in this embodiment, compared with the millimeter-wave communication component configuration of multiple millimeter-wave transmitting modules + multiple millimeter-wave receiving modules, eliminates the configuration of complex data stream processing modules (including each stream signal receiving unit and stream signal processing unit), which can greatly simplify the data processing of the millimeter-wave receiving module, the processing of multiple data streams, and the complexity of the device.

[0083] Please see Figure 6 , Figure 6 This is a schematic diagram of the millimeter-wave communication component in a non-contact rotation system based on millimeter-wave communication, provided as an embodiment of the present invention. This embodiment is a further extension of any of the above embodiments, and a detailed description of the millimeter-wave communication component is provided.

[0084] The non-contact rotation system based on millimeter-wave communication in this embodiment includes a millimeter-wave communication component 30 comprising multiple millimeter-wave transmitting modules 31 and a millimeter-wave receiving module 32.

[0085] like Figure 6 As shown, each millimeter-wave transmitting module 31 includes a transmitting unit 311 and a transmitting antenna 312 connected thereto; specifically, the transmitting unit 31 includes an oscillator, a modulator, and a radio frequency amplifier; the output terminal of the oscillator is connected to the first input terminal of the modulator; the second input terminal of the modulator serves as the input terminal of the transmitting unit and can be connected to the signal output terminal of the X-ray receiving unit, and its output terminal is connected to the input terminal of the radio frequency amplifier; the output terminal of the radio frequency amplifier serves as the output terminal of the transmitting unit and can be connected to the transmitting antenna 312.

[0086] like Figure 6As shown, the millimeter-wave receiving module 32 includes a receiving unit 321 and a receiving antenna 322 connected thereto. Specifically, the receiving unit 321 includes a low-noise amplifier and an envelope detector; the input terminal of the low-noise amplifier is connected to the receiving antenna, and its output terminal is connected to the input terminal of the envelope detector; the output terminal of the envelope detector serves as the output terminal of the receiving unit.

[0087] The working principle of the millimeter-wave communication component described in this embodiment is as follows:

[0088] The X-ray receiving unit on the rotating component transmits the collected data signal to the transmitting unit of the millimeter-wave transmitting module in the millimeter-wave communication component. The modulator in the transmitting unit modulates the signal according to the modulation signal generated by the oscillator and converts it into a wireless signal. After being amplified by the transmitting radio frequency amplifier, it is transmitted through the transmitting antenna. As the rotating component rotates, the millimeter-wave radiation range of each transmitting antenna will sequentially cover the millimeter-wave receiving module on the fixed component. The receiving antenna will continuously receive the wireless signal and convert it into a corresponding electrical signal. After being amplified by the receiving radio frequency amplifier in the receiving unit, it is demodulated by the envelope detector to restore the data signal collected by the X-ray receiving unit. Finally, it is transmitted to the signal receiving unit through the signal line.

[0089] In some specific embodiments, the millimeter-wave transmitting module is a millimeter-wave transmitting chip; the receiving unit in the millimeter-wave receiving module is a millimeter-wave receiving chip. By embedding the transmitting antenna and the transmitting unit into the chip, chip-level packaging is achieved, which is not only safer and more reliable, but also lower in cost and enables miniaturization.

[0090] This embodiment of the non-contact rotation system based on millimeter-wave communication utilizes millimeter-wave wireless communication technology and a millimeter-wave communication component to achieve high-capacity, continuous, and stable non-contact data transmission between rotating and fixed components. Millimeter-wave communication technology offers advantages such as high bandwidth, high transmission rate, low latency, strong directionality, miniaturization, and integration. In particular, the millimeter-wave frequency band provides extremely high bandwidth, easily achieving transmission rates exceeding Gbps. Therefore, the millimeter-wave communication component in this embodiment can achieve a maximum single-channel rate of 10Gbps, and a multi-channel design can achieve even higher transmission rates, making it particularly suitable for X-ray data transmission requiring high capacity and high fidelity. Furthermore, the millimeter-wave communication component also features safety, reliability, simple structure, and low cost.

[0091] Please see Figure 5 and Figure 7This embodiment further extends any of the above embodiments to provide a rotating CT system, namely a spiral CT system. The rotating CT system provided in this embodiment includes the non-contact rotating system based on millimeter-wave communication provided in any of the above embodiments, and a terminal processor; the terminal processor is connected to the signal output terminal of the non-contact rotating system based on millimeter-wave communication.

[0092] like Figure 5 As shown, the rotating CT system provided in this embodiment includes a fixation component 10, a rotating component 20, a millimeter-wave communication component 30, a radiation emitting unit 40, a radiation receiving unit 50, and a terminal processor 60. Specifically, the radiation emitting unit is an X-ray emitting unit, and the radiation receiving unit is an X-ray receiving unit. The structure, function, and connection relationships of each component will not be described in detail here; please refer to the description in the above embodiment for further details.

[0093] The data transmission architecture of the rotating CT system will be described in detail below:

[0094] In a rotating CT system, X-rays emitted by the X-ray emitting unit on the rotating component are received by the X-ray receiving unit at the other end of the rotating component after penetrating an object or human body; for example... Figure 7 As shown, the X-ray receiving unit includes a data acquisition component (i.e., the data acquisition in the figure) and a data processing component (i.e., the data processing in the figure). The data acquisition component is used to convert the acquired analog X-ray signals into digital biological internal structure image data. The data processing component is used to unpack and package the digital biological internal structure image data according to the number of millimeter-wave transmitting modules, and distribute it to each millimeter-wave transmitting module (i.e., TX1 to TXn modules in the figure). Each millimeter-wave transmitting module converts the received digital signal data packets into millimeter-wave wireless signals and transmits them. As the rotating component rotates, the receiving antenna of the millimeter-wave receiving module will be continuously and seamlessly covered by the millimeter-wave radiation range, that is, it can receive millimeter-wave wireless signals uninterruptedly. The receiving antenna will convert the received millimeter-wave wireless signals into electrical signals and transmit them to the corresponding receiving unit (i.e., RX in the figure). The receiving unit will convert the received electrical signals into corresponding digital signal data packets and then transmit them to the terminal processor. The terminal processor will analyze the received biological internal structure image data and display the analysis results through the terminal.

[0095] As the rotation angle changes, the transmitting antenna covering the receiving antenna continuously changes. Since each transmitting antenna emits the same millimeter-wave signal, and the radiation range of the millimeter-wave signal between adjacent transmitting antennas overlaps, the receiving antenna can continuously receive the millimeter-wave signal, ensuring the continuity of data transmission between the rotating and fixed components. Subsequently, by processing the data stream received by the millimeter-wave receiving module, the original complete data stream can be accurately recovered, thereby ensuring the reliability of data transmission.

[0096] The rotating CT system provided in this embodiment, based on millimeter-wave wireless communication technology, can transmit large amounts of data acquired on the rotating component to the fixed component for subsequent processing via single-channel or multi-channel non-contact wireless transmission with high speed, high stability, high reliability, and low cost. This not only solves the signal quality problems caused by unstable contact and the lifespan issues due to contact wear in existing rotating CT systems' slip ring communication schemes, but also reduces design and cost compared to optical module communication schemes.
