Technical Field

[0001] This application relates to the field of medical device communication technology, and in particular to a data transmission system and a medical imaging device. Background Technology

[0002] Computed Tomography (CT) uses an X-ray tube and a detector to scan a section of the human body. The X-ray tube and detector are mounted opposite each other on the rotor of the CT equipment. As the rotor rotates, it needs to transmit the scan data collected by the detector to the stator in real time for subsequent image reconstruction processing.

[0003] Traditionally, CT equipment has a data transmission slip ring on its rotor. This slip ring uses capacitive coupling between the rotor's transmitting antenna and the stator's receiving antenna to achieve wireless data transmission between the rotor and the stator.

The first adjustment unit 1021 is used to adjust the direction of the first signal, and the second adjustment unit 1022 is used to adjust the direction of the second signal.

[0013] The second adjustment component 202 includes a third adjustment unit 2021 and a fourth adjustment unit 2022.

[0015] The third adjustment unit 2021 is a focusing light wedge, and the fourth adjustment unit 2022 is a planar light wedge.

[0016] In one embodiment, the first transceiver module 10 is a first optical transceiver module, and the second transceiver module 20 is a second optical transceiver module; or...

[0017] The first transceiver module 10 is a first electromagnetic wave transceiver module, and the second transceiver module 20 is a second electromagnetic wave transceiver module.

[0018] In one embodiment, the system further includes a controller 30, which is connected to the second transceiver module 20;

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] In the medical field, there are many types of medical imaging equipment, among which computed tomography (CT) equipment is one. CT equipment mainly includes an X-ray tube, detectors, a scanning gantry, and a scanning bed. The X-ray tube and detectors are mounted on a rotating part (which can be called a rotor) within the scanning gantry. During the rotational scanning of the patient, the rotating part drives the X-ray tube and detectors to perform tomographic scanning around the patient's scanned area. Simultaneously, during the scanning process, the detectors acquire attenuated signals passing through the patient's scanned area in real time and transmit the data acquired by the detectors to the stator through a data transmission method between the rotating part and the stationary part (which can be called the stator) of the scanning gantry. This data is then used for subsequent data processing and image reconstruction to obtain a CT image of the scanned area.

[0042] In related technologies, data transmission methods between the rotor and stator of a scanning gantry can include: using slip rings and carbon brushes for data transmission, i.e., setting slip rings on the circumference of the rotor and carbon brushes at predetermined positions on the stator to achieve data transmission; or using capacitive coupling for data transmission, i.e., setting a transmitting antenna on the rotor and a receiving antenna on the stator, and achieving wireless data transmission between the rotor and stator through a capacitive coupler between the transmitting and receiving antennas. It should be noted that data transmission between the rotor and stator can both transmit data collected by the detectors on the rotor to the stator and transmit external control signals to the rotor, thereby enabling external devices (such as computer equipment in the operating room) to control the medical imaging equipment.

[0043] In some implementations, a combination of slip ring brushes and capacitive coupling can be used. The slip ring brushes transmit low-speed external control signals, while the capacitive coupling transmits high-speed scan data. However, existing data transmission methods suffer from short transmission distances and low theoretical bandwidth limits during scan data transmission, and also place high demands on the installation between the rotor and stator. Capacitive coupling also suffers from low signal interference immunity. Furthermore, due to limitations in antenna manufacturing processes, the length of the transmitting antenna is finite. As the CT aperture increases, multiple transmitting antennas need to be spliced ​​together, further increasing the difficulty of slip ring installation.

[0044] Based on this, this application proposes a new data transmission method, which places the data receiving end of the stator outside the scanning frame and on the rotating shaft of the rotor, and realizes long-distance communication through optical transmission or electromagnetic wave transmission. This data transmission method can reduce the installation difficulty between the rotor and the stator (the stationary part on the scanning frame) without increasing the internal size of the existing frame. Moreover, compared with the existing capacitive coupling, which requires antennas to be set around the rotor slip ring, and the limitation of the rotor aperture size on the processing size of the slip ring antenna leads to the limitation of transmission bandwidth, this application adopts optical transmission or electromagnetic wave transmission, so that the rotor aperture size no longer affects the transmission bandwidth of the slip ring, which can effectively meet the needs of large-aperture CT.

[0045] Furthermore, by adopting the data transmission method of this application, bidirectional communication can be used to transmit both detector scanning data and control signals, thereby improving the overall performance of the data transmission system.

[0046] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0047] Figure 1 This is a schematic diagram of the data transmission system provided in an embodiment of this application. Figure 1 As shown, this system can be applied to medical imaging equipment, including: a stationary part (such as the housing of a scanning gantry, not shown in the figure) and a rotating part that is rotated and coupled within the stationary part. It may also include: a first transceiver module 10 and a second transceiver module 20. The first transceiver module 10 is disposed on the rotating part of the medical imaging equipment, and the second transceiver module 20 is located on the rotation axis of the rotating part. The first transceiver module 10 is used to send a first signal to the second transceiver module 20 and / or to receive a second signal sent by the second transceiver module 20. The first signal may carry data to be transmitted collected by a detector in the medical imaging equipment, and the second signal may carry control signals for the medical imaging equipment.

[0048] For example, one or more first transceiver modules 10 can be provided at any position on the circumferential end face of the rotating part. For instance, multiple first transceiver modules 10 can be provided at equal intervals on the circumferential end face of the rotating part, and each first transceiver module 10 can face the second transceiver module 20. That is, when the second transceiver module 20 is located on one side of the scanning bed of the medical imaging device, each first transceiver module 10 can be provided on the side of the rotating part close to the scanning bed; when the second transceiver module 20 is located on the side of the medical imaging device away from the scanning bed, each first transceiver module 10 can be provided on the side of the rotating part away from the scanning bed. This is so that the signal transmission path of each first transceiver module 10 can point to the second transceiver module 20 during the rotation of the rotating part, thereby realizing signal transmission between the first transceiver module 10 and the second transceiver module 20.

[0049] For example, the second transceiver module 20 can be disposed on the rotation axis of the rotating part, or disposed within a preset range of the rotation axis of the rotating part; the second transceiver module 20 can be independent of the scanning gantry of the medical imaging equipment and located outside the scanning gantry; for example, the second transceiver module 20 can be disposed on the side away from the scanning bed, and the distance between the second transceiver module 20 and the rotation center of the scanning gantry is within a preset distance range. The location of the second transceiver module 20, that is, the distance between the second transceiver module 20 and the rotation center of the scanning gantry, should be able to meet the distance the scanning bed moves into the gantry, so as to avoid the location of the second transceiver module 20 affecting the movement of the scanning bed.

[0050] In this example, the first transceiver module 10 can be connected to the data acquisition module of the detector on the rotating part to obtain the scan data collected by the detector from the data acquisition module, i.e., the data to be transmitted. In an optional implementation, a data acquisition module, such as a Printed Circuit Board Assembly (PCBA), can be set between the first transceiver module 10 and the detector. This data acquisition module is connected to the detector and is used to receive the scan data collected by the detector and transmit the data to the first transceiver module 10 so that the first transceiver module 10 can send the scan data to the second transceiver module 20.

[0051] For example, when there are multiple first transceiver modules 10, the data acquisition module can split the data to be transmitted collected by the detector into multiple data packets, so that the multiple data packets can be transmitted to the second transceiver module 20 through the multiple first transceiver modules 10 respectively; based on this, when the second transceiver module 20 receives the data packets sent by the multiple first transceiver modules 10 respectively, the complete data to be transmitted can be obtained by splicing the multiple data packets.

[0052] For example, the data acquisition module can also transmit the complete data to be transmitted collected by the detector to the second transceiver module 20 through each of the first transceiver modules 10, so that the second transceiver module 20 can receive the complete data to be transmitted, avoid data loss during data transmission, and improve the accuracy of data transmission.

[0053] For the first transceiver module 10, it can convert the data to be transmitted into a first signal carrying the data to be transmitted, and send the first signal to the second transceiver module 20. Optionally, the first signal can be an optical signal or an electromagnetic wave signal, etc. That is, the first transceiver module 10 can be a first optical transceiver module or a first electromagnetic wave transceiver module. Correspondingly, the second transceiver module 20 can also be a second optical transceiver module or a second electromagnetic wave transceiver module. It should be noted that the types of the first transceiver module 10 and the second transceiver module 20 should be consistent.

[0054] It should be noted that the data to be transmitted through the first transceiver module 10 can be the scan data collected by the detector, or the data after data preprocessing of the scan data collected by the detector through the data acquisition module; optionally, data preprocessing can include, but is not limited to, data smoothing, noise reduction, filtering, correction, reconstruction and other processing operations.

[0055] In addition, the first transceiver module 10 can not only send the data collected by the detector to the second transceiver module 20 in the form of a first signal to realize the transmission of scan data, but also receive the control signals sent by the second transceiver module 20 for the medical imaging equipment to realize the transmission of control signals, thereby realizing the control of the medical imaging equipment by external devices.

[0056] For example, the second transceiver module 20 can be connected to an external device to receive control information sent by the external device, convert the control information into a second signal carrying the control information, and send it to the first transceiver module 20; correspondingly, the first transceiver module 10 can also be connected to the controller in the medical imaging device to send the received second signal to the controller of the medical imaging device to instruct the controller to control the medical imaging device according to the control information carried in the second signal.

[0057] In other words, the first transceiver module 10 may include a first transmitter and a first receiver, and the second transceiver module 20 may include a second transmitter and a second receiver. The first transmitter in the first transceiver module 10 can be connected to the detector's data acquisition module to acquire the data to be transmitted collected by the detector from the data acquisition module, and convert the data to be transmitted into a first signal to be sent to the second transceiver module 20. The second receiver in the second transceiver module 20 receives the first signal, parses it to obtain the data to be transmitted collected by the detector, and then performs image reconstruction based on the data to be transmitted to obtain the corresponding reconstructed image. For example, the second receiver in the second transceiver module 20 can be connected to a reconstruction host to send the data to be transmitted obtained from the parsed first signal to the reconstruction host, where image reconstruction processing is performed to obtain the reconstructed image.

[0058] In addition, the second transmitter in the second transceiver module 20 can be connected to an external device to obtain control information from the external device and convert the control information into a second signal to be sent to the first transceiver module 10; the first receiver in the first transceiver module 10 receives the second signal and parses it to obtain the control information; the first receiver can be connected to the controller in the medical imaging device to send the parsed control information to the controller of the medical imaging device to instruct the controller to control the medical imaging device based on the control information.

[0059] For example, the external device may include a control device located in the operating room, through which the user can control the medical imaging equipment in the scanning room, thereby realizing medical scanning. For example, the reconstruction host may include the control device located in the operating room, or it may include a local server, a remote server, a cloud server, etc.

[0060] This embodiment proposes a data transmission system, which includes a stationary part and a rotating part that is rotated and coupled within the stationary part. It also includes a first transceiver module and a second transceiver module. The first transceiver module is disposed on the rotating part, and the second transceiver module is located on the rotation axis of the rotating part. The first transceiver module is used to send a first signal to the second transceiver module and / or to receive a second signal sent by the second transceiver module. In other words, the data transmission system proposed in this application allows one end of the signal transmission to be placed on the rotating part of the scanning gantry of the medical imaging equipment, while the other end is placed outside the medical imaging equipment and on the rotation axis of the scanning gantry. A data transmission path is formed between the medical imaging equipment and the external device using light waves or electromagnetic waves. This not only increases the data transmission distance between the medical imaging equipment and the external device but also increases the data transmission bandwidth and rate. Furthermore, by setting transceiver modules on both the medical imaging equipment and the external device, and using the same data transmission path, not only can the scanning data of the medical imaging equipment be transmitted, but also the control signals from the external device to the medical imaging equipment can be transmitted. Therefore, this data transmission system enables bidirectional data transmission, avoiding the need for multiple data transmission paths within the medical imaging equipment, thereby reducing the construction cost of the data transmission links and improving the efficiency of bidirectional data transmission.

[0061] In an exemplary embodiment, when using light waves or electromagnetic waves for data transmission, to ensure that the first transceiver module 10 mounted on the rotating part always points to the second transceiver module 20 on the rotating shaft during the rotation of the rotating part—that is, the light signal or electromagnetic wave signal sent by the first transceiver module 10 needs to be accurately projected to the second transceiver module 20, and the light signal or electromagnetic wave signal sent by the second transceiver module 20 needs to be accurately projected to the first transceiver module 10—in this example, for the first transceiver module 10, refer to... Figure 2 As shown, the first transceiver module 10 may include a first transceiver component 101 and a first adjustment component 102; wherein, the first adjustment component 102 may be disposed on the signal transmission path of the first transceiver component 101, that is, the first adjustment component 102 is disposed between the first transceiver component 101 and the second transceiver module 20.

[0062] The first adjustment component 102 is used to adjust the direction of the first signal and / or the second signal.

[0063] For example, the position of the first adjustment component 102 can be fixed or adaptively adjusted; that is, during the rotation of the rotating part, both the first transceiver component 101 and the first adjustment component 102 rotate together with the rotating part, and during the rotation, the first adjustment component 102 can be fixed relative to the first transceiver component 101 or adjusted in real time, so that after the first adjustment component 102 adjusts the direction of the first signal sent by the first transceiver component 101, the second transceiver module 20 can accurately receive the first signal; and / or, after the direction of the second signal sent by the second transceiver module 20 is adjusted, the first transceiver component 101 can accurately receive the second signal.

[0064] For example, when transmitting data based on light waves, the first transceiver module 10 can be a first optical signal transceiver module, and the second transceiver module 20 can be a second optical signal transceiver module; when the first transceiver module 10 includes a first transceiver component 101 and a first adjustment component 102, the first transceiver component 101 can be a first optical signal transceiver, and the first adjustment component 102 can be a first optical wedge.

[0065] For example, when data transmission is based on electromagnetic waves, the electromagnetic waves include, but are not limited to, terahertz waves, millimeter waves, etc.; when the electromagnetic wave is terahertz, the first transceiver module 10 can be a first terahertz transceiver module, and the second transceiver module 20 can be a second terahertz transceiver module; when the first transceiver module 10 includes a first transceiver component 101 and a first adjustment component 102, the first transceiver component 101 can be a first terahertz transceiver, and the first adjustment component 102 can be a first terahertz diverter.

[0066] For example, when the electromagnetic wave is a millimeter wave, the first transceiver module 10 can be a first millimeter wave transceiver module, and the second transceiver module 20 can be a second millimeter wave transceiver module; when the first transceiver module 10 includes a first transceiver component 101 and a first adjustment component 102, the first transceiver component 101 can be a first millimeter wave transceiver, and the first adjustment component 102 can be a rotatable first millimeter wave transceiver antenna.

[0067] For example, to ensure the reliability and accuracy of the bidirectional signal transmission path, that is, to ensure that the second transceiver module 20 can accurately receive the first signal sent by the first transceiver module 10, and to ensure that the first transceiver module 10 can accurately receive the second signal sent by the second transceiver module 20; as Figure 3As shown, the second transceiver module 20 may include a second transceiver component 201 and a second adjustment component 202; wherein, the second adjustment component 202 is disposed on the signal transmission path of the second transceiver component 201, that is, the second adjustment component 202 may be disposed between the first transceiver module 10 and the second transceiver component 201.

[0068] The second adjustment component 202 is used to adjust the direction of the first signal and / or the second signal.

[0069] For example, the position of the second adjustment component 202 relative to the second transceiver component 201 can be fixed or flexibly adjustable. That is, during the rotation of the first transceiver module 10 following the rotating part, in order to accurately project the signal emitted by the first transceiver module 10 into the second transceiver component 201, the second adjustment component 202 can adjust the direction of the first signal emitted by the first transceiver module 10 during the rotation so that the second transceiver component 201 can accurately receive the first signal emitted by the first transceiver module 10. Similarly, the second adjustment component 202 can also adjust the direction of the second signal emitted by the second transceiver component 201 so that the first transceiver module 10 during the rotation can also accurately receive the second signal emitted by the second transceiver component 201.

[0070] For example, when transmitting data based on light waves, the first transceiver module 10 can be a first optical signal transceiver module, and the second transceiver module 20 can be a second optical signal transceiver module; when the second transceiver module 20 may include a second transceiver component 201 and a second adjustment component 202, the second transceiver component 201 can be a second optical signal transceiver, and the second adjustment component 202 can be a second optical wedge.

[0071] For example, when data transmission is based on electromagnetic waves and the electromagnetic waves are terahertz, the first transceiver module 10 can be a first terahertz transceiver module and the second transceiver module 20 can be a second terahertz transceiver module; when the second transceiver module 20 may include a second transceiver component 201 and a second adjustment component 202, the second transceiver component 201 can be a second terahertz transceiver and the second adjustment component 202 can be a second terahertz diverter.

[0072] For example, when data transmission is based on electromagnetic waves and the electromagnetic waves are millimeter waves, the first transceiver module 10 can be a first millimeter wave transceiver module, and the second transceiver module 20 can be a second millimeter wave transceiver module; when the second transceiver module 20 may include a second transceiver component 201 and a second adjustment component 202, the second transceiver component 201 can be a second millimeter wave transceiver, and the second adjustment component 202 can be a rotatable second millimeter wave transceiver antenna.

[0073] In this example, to ensure that the signal path of the first transceiver module on the rotating part always points to the second transceiver module on the external stator, and that the signal path of the second transceiver module on the external stator always points to the first transceiver module on the rotating part, thereby enabling the second transceiver module to accurately receive the first signal sent by the first transceiver module, and enabling the first transceiver module to accurately receive the second signal sent by the second transceiver module; the first transceiver module may include a first transceiver component and a first adjustment component, and the first adjustment component is disposed on the signal transmission path of the first transceiver component to adjust the direction of the first signal and / or the second signal; the second transceiver module may include a second transceiver component and a second adjustment component, and the second adjustment component is disposed on the signal transmission path of the second transceiver component to adjust the direction of the first signal and / or the second signal; thereby ensuring the reliability and accuracy of bidirectional signal transmission.

[0074] In one exemplary embodiment, such as Figure 4 As shown, when the first transceiver module 10 includes a first transceiver component 101 and a first adjustment component 102, the first adjustment component 102 may further include a first adjustment unit 1021 and / or a second adjustment unit 1022. The first adjustment unit 1021 is disposed on the signal transmission path of the first transceiver component 101, and the second adjustment unit 1022 is disposed on the signal reception path of the first transceiver component 101. Based on this, the first adjustment unit 1021 is used to adjust the direction of the first signal; the second adjustment unit 1022 is used to adjust the direction of the second signal.

[0075] In other words, on one side of the rotating part, different signal adjustment units are set for the transmission path of scanning data and the reception path of control signals respectively; when the first transceiver component 101 transmits the first signal, the first signal is transmitted to the second transceiver module 20 after the direction is adjusted by the first adjustment unit 1021 on the signal transmission path; when the first transceiver component 101 receives the second signal, the second signal transmitted by the second transceiver module 20 is transmitted to the first transceiver component 101 in the first transceiver module 10 after the direction is adjusted by the second adjustment unit 1022 on the signal reception path in the first transceiver module 10.

[0076] For example, adjusting the signal direction by the adjustment unit may include changing the transmission direction of the signal, or it may include not changing the transmission direction of the signal; that is, the adjustment unit may adjust the direction of the input signal so that the direction of the output signal is different from that of the input signal; or it may not adjust the direction of the input signal, that is, keep the transmission direction of the input signal so that the direction of the output signal is the same as that of the input signal.

[0077] For example, the first adjustment unit 1021 can maintain the transmission direction of the first signal, so that the first signal emitted by the first transceiver component 101 is transmitted to the second transceiver module 20 after passing through the first adjustment unit 1021; the second adjustment unit 1022 can change the transmission direction of the second signal, so that the second signal emitted by the second transceiver module 20 is converged to the first transceiver component 101 after passing through the second adjustment unit 1022, so that the first transceiver component 101 can accurately receive the second signal.

[0078] For example, when the first adjustment component 102 is a first optical wedge, the first adjustment unit 1021 can be a planar optical wedge, that is, it does not change the light direction of the first signal; the second adjustment unit 1022 can be a focusing optical wedge, that is, it focuses the light of the second signal together, so that the first transceiver component 101 receives the complete second signal.

[0079] For example, such as Figure 5 As shown, when the second transceiver module 20 includes a second transceiver component 201 and a second adjustment component 202, the second adjustment component 202 may further include a third adjustment unit 2021 and a fourth adjustment unit 2022. The third adjustment unit 2021 is disposed on the signal receiving path of the second transceiver component 201, and the fourth adjustment unit 2022 is disposed on the signal transmitting path of the second transceiver component 201. Based on this, the third adjustment unit 2021 is used to adjust the direction of the first signal; the fourth adjustment unit 2022 is used to adjust the direction of the second signal.

[0080] In other words, on the external stator side, different signal adjustment units are set for the receiving path of scanning data and the transmitting path of control signals respectively; when the second transceiver component 201 receives the first signal, the first signal sent by the first transceiver module 10 is transmitted to the second transceiver component 201 in the second transceiver module 20 after the direction is adjusted by the third adjustment unit 2021 on the signal receiving path of the second transceiver module 20; when the second transceiver component 201 sends the second signal, the second signal is transmitted to the first transceiver module 10 after the direction is adjusted by the fourth adjustment unit 2022 on the signal transmitting path.

[0081] Similarly, the adjustment unit may adjust the signal direction by changing the transmission direction of the signal or not changing the transmission direction of the signal. For example, the third adjustment unit 2021 may change the transmission direction of the first signal so that the first signal emitted by the first transceiver component 101 is converged to the second transceiver component 201 after passing through the third adjustment unit 2021, so that the second transceiver component 201 can accurately receive the first signal. The fourth adjustment unit 2022 may not change the transmission direction of the second signal so that the second signal emitted by the second transceiver module 20 is transmitted to the first transceiver module 10 after passing through the fourth adjustment unit 2022.

[0082] For example, when the second adjustment component 202 is a second optical wedge, the third adjustment unit 2021 can be a focusing optical wedge, that is, to focus the light of the first signal together so that the second transceiver component 201 receives the complete first signal; the fourth adjustment unit 2022 can be a planar optical wedge, that is, it does not change the light direction of the second signal.

[0083] In this embodiment, on one hand, distinguishing from the signal transmission path and signal reception path on the rotating part side, the first adjustment component may include a first adjustment unit and a second adjustment unit. The first adjustment unit is disposed on the signal transmission path of the first transceiver component and is used to adjust the direction of the first signal transmitted by the first transceiver component. The second adjustment unit is disposed on the signal reception path of the first transceiver component and is used to adjust the direction of the second signal to be received by the first transceiver component. On the other hand, distinguishing from the signal reception path and signal transmission path on the external stator side, the second adjustment component includes a third adjustment unit and a fourth adjustment unit. The third adjustment unit is disposed on the signal reception path of the second transceiver component and is used to adjust the direction of the first signal to be received by the second transceiver component. The fourth adjustment unit is disposed on the signal transmission path of the second transceiver component and is used to adjust the direction of the second signal transmitted by the second transceiver component. Using this data transmission system can improve the reliability and accuracy of bidirectional signal transmission.

[0084] In one exemplary embodiment, in conjunction with the above... Figure 2 and Figure 3 The first transceiver module 10 may include a first transceiver component 101 and a first adjustment component 102, and the second transceiver module 20 may include a second transceiver component 201 and a second adjustment component 202; wherein, the first adjustment component 102 is disposed between the first transceiver component 101 and the second adjustment component 202, and is located on the side closer to the first transceiver component 101; the second adjustment component 202 is disposed between the first adjustment component 102 and the second transceiver component 201, and is located on the side closer to the second transceiver component 201.

[0085] The first adjustment component 102 can be used to adjust the direction of the first signal and / or the second signal, and the second adjustment component 202 can be used to adjust the direction of the first signal and / or the second signal.

[0086] In one optional implementation, the first adjustment component 102 can be used to adjust the direction of the second signal transmitted by the second transceiver component 201, and the second adjustment component 202 can also be used to adjust the direction of the first signal transmitted by the first transceiver component 101. That is, when the first transceiver component 101 transmits the first signal to the second transceiver component 201, the first adjustment component 102 does not adjust the direction of the first signal, but adjusts the direction of the first signal and transmits it to the second transceiver component 201, so that the second transceiver component 201 can accurately receive the first signal; when the second transceiver component 201 transmits the second signal to the first transceiver component 101, the second adjustment component 202 does not adjust the direction of the second signal, but adjusts the direction of the second signal and transmits it to the first transceiver component 101, so that the first transceiver component 101 can accurately receive the second signal.

[0087] For example, the first adjustment component 102 may include a first adjustment unit 1021 disposed in the signal transmission path and a second adjustment unit 1022 disposed in the signal reception path, and the second adjustment component 202 may include a third adjustment unit 2021 disposed in the signal reception path and a fourth adjustment unit 2022 disposed in the signal transmission path; wherein, the first adjustment unit 1021 may not adjust the direction of the first signal transmitted by the first transceiver component 101, but adjusts the direction of the first signal transmitted by the first transceiver component 101 through the third adjustment unit 2021, so that the second transceiver component 201 can completely and accurately receive the first signal transmitted by the first transceiver component 101; the fourth adjustment unit 2022 may not adjust the direction of the second signal transmitted by the second transceiver component 201, but adjusts the direction of the second signal transmitted by the second transceiver component 201 through the second adjustment unit 1022, so that the first transceiver component 101 can completely and accurately receive the second signal transmitted by the second transceiver component 201.

[0088] The data transmission system in this embodiment ensures that the first transceiver module on the rotating part accurately receives the second signal sent by the second transceiver module on the stator, and that the second transceiver module on the stator accurately receives the first signal sent by the first transceiver module on the rotating part. This improves the reliability and accuracy of bidirectional signal transmission while achieving bidirectional signal transmission.

[0089] In one exemplary embodiment, such as Figure 6As shown, the data transmission system may further include a controller 30, which is connected to the second transceiver module 20; wherein the controller 30 is used to adjust the signal receiving range of the second transceiver module 20 when the power of the first signal is detected to be less than or equal to a preset power threshold.

[0090] Exemplarily, the controller 30 can be located in the same position as the second transceiver module 20, or in a different position. The controller 30 can be connected to the second transceiver module 20 via wired or wireless means to achieve data transmission. Exemplarily, when detecting the power of the first signal, the controller 30 can obtain the power of the first signal by detecting the first signal passing through the second adjustment component 202 in the second transceiver module 20; it can also obtain the power of the first signal by checking the first signal collected by the second transceiver component 201 in the second transceiver module 20; of course, it can also obtain the power of the first signal by detecting the power of the first signal received by the second adjustment component 202, etc. The method of detecting the power of the first signal is not limited in this embodiment.

[0091] For example, when the controller 30 detects the power of the first signal and determines that the power of the first signal is less than or equal to a preset power threshold, it can adjust the signal reception range of the second transceiver module 20. For example, the controller 30 can send an adjustment command to the second transceiver module 20 to instruct the second transceiver module 20 to adjust its own signal reception range; the controller 30 can also directly control the second transceiver module 20 and adjust its signal reception range.

[0092] The preset power threshold can be related to the rated conversion power of the second transceiver module 20 itself. Typically, when the power of the first signal received by the second transceiver module 20 is greater than or equal to its rated conversion power, the second transceiver module 20 can recover complete scan data based on the received first signal; otherwise, it cannot recover complete scan data, resulting in data loss. This preset power threshold can be equal to or greater than the rated conversion power. Furthermore, the selection of the second transceiver module 20, i.e., its rated conversion power, is related to the data transmission bandwidth. The data transmission bandwidth is directly proportional to the rated conversion power of the second transceiver module 20. In practical applications, a second transceiver module 20 that meets the required data transmission bandwidth can be selected for scanning data transmission.

[0093] For example, in practical applications, if there is no second transceiver module 20 to meet the data transmission bandwidth requirements, higher bandwidth data transmission can be achieved by increasing the transmission power of the first transceiver module 10 or reducing the signal transmission loss rate. Furthermore, the higher the data transmission bandwidth, the greater the pulse frequency of the photoelectric converter in the first transceiver module 10, and the faster the corresponding data transmission rate.

[0094] For example, the controller 30 can adjust the signal receiving range of the second transceiver module 20 by adjusting the second adjustment component 202 in the second transceiver module 20; for example, the position and / or orientation of the second adjustment component 202 can be adjusted to increase the signal receiving range of the second adjustment component 202, thereby increasing the signal power of the first signal received by the second transceiver module 201.

[0095] For example, when adjusting the position and / or orientation of the second adjustment component 202, the second adjustment component 202 may be mounted on an adjustment device, which may include, but is not limited to, a gimbal; the controller 30 may control the adjustment device to move according to a preset adjustment strategy to change the position and / or orientation of the second adjustment component 202. The preset adjustment strategy may include at least one of position movement direction, position movement distance, rotation direction, and rotation angle.

[0096] It should be noted that the controller 30 can adjust the second adjustment component 202 at least once according to the preset adjustment strategy. After each adjustment, the power of the first signal after adjustment can be re-detected until the power of the first signal is greater than or equal to the preset power threshold.

[0097] For example, before the medical imaging equipment is manufactured or before image scanning is performed, a pre-test can be conducted to check whether the power of the first signal received by the second transceiver module meets the power requirements, that is, whether the power of the first signal is greater than or equal to a preset power threshold. If the power requirements are met, image scanning can be performed normally. If the power requirements are not met, the power of the first signal received by the second transceiver module can be increased by adjusting the signal receiving range of the second transceiver module to ensure stable transmission of scanning data.

[0098] For example, during image scanning, the power of the first signal received by the second transceiver module can be detected in real time. If the power of the first signal received by the second transceiver module is less than a preset power threshold, it can be considered that the second transceiver module is unable to completely receive the scan data sent by the first transceiver module, or that the scan data received by the second transceiver module is incomplete. In this case, the current scan can be stopped, and the second transceiver module can be adjusted and corrected to ensure that the power of the first signal received by the second transceiver module meets the power requirements before re-scanning the image. Using this method, it is possible to avoid patients discovering missing image scan data only after a complete image scan, thus preventing them from receiving excessive radiation. In addition, if incomplete scan data received by the stator is detected during the scan and the current scan is stopped in time, the second transceiver module on the stator can be adjusted or corrected immediately, and the image scan can be performed again after adjustment, thereby shortening the overall image scan time and improving image scan efficiency.

[0099] In one exemplary embodiment, such as Figure 7 As shown, the above data transmission system may further include a power detection device 40, which is connected to the second transceiver module 20 and the controller 30 respectively; wherein, the power detection device 40 can be used to detect the power information of the first signal received by the second transceiver module and send the power information to the controller 30.

[0100] For example, the controller 30 can detect the power of the first signal by detecting the power of the first signal received by the second transceiver module through the power detection device 40 to obtain the power information of the first signal. In this way, the controller 30 can obtain the power information of the first signal from the power detection device 40. The power information of the first signal may include the power value of the first signal received by the second transceiver module at at least one moment. Furthermore, the controller 30 can determine the relationship between the power value of the first signal and a preset power threshold, so as to adjust the signal receiving range of the second transceiver module when it is determined that the power of the first signal is less than the preset power threshold.

[0101] For example, when the second transceiver module includes a second transceiver component and a second adjustment component, the power detection device 40 can be connected to the second transceiver component to detect the power of the first signal received by the second transceiver component. Alternatively, the power detection device 40 can also detect the power of the first signal received by the second adjustment component to obtain the power information of the first signal.

[0102] It should be noted that the power detection device 40 may include, but is not limited to, any form or structure of power detector, power detection equipment, power detection module, etc. In this application embodiment, the type and structure of the power detection device 40 are not limited.

[0103] For example, when the power information of the first signal includes the power values ​​of the first signal at multiple times, the controller 30 may adjust the signal receiving range of the second transceiver module in the following ways: if the controller 30 determines that the power value of the first signal at the current time is less than a preset power threshold, adjust the signal receiving range of the second transceiver module; or, if the controller 30 determines that the power value of the first signal at a consecutive preset number of times is less than the preset power threshold, adjust the signal receiving range of the second transceiver module. Adjusting the signal receiving range of the second transceiver module may include adjusting the position and / or orientation of the second adjustment component in the second transceiver module to adjust the signal receiving range of the second adjustment component, thereby increasing the signal power of the first signal received by the second transceiver module.

[0104] For example, when the second adjustment component is an optical wedge, the position and / or direction of the optical wedge can be adjusted so that more of the first (optical) signal can be irradiated in the central area of ​​the optical wedge, thereby improving the focusing effect of the first (optical) signal and thus increasing the signal power of the first (optical) signal received by the second transceiver component.

[0105] For example, if the power of the first signal is less than a preset power threshold during image scanning, one optional implementation is to quickly adjust the signal receiving range of the second transceiver module without stopping the system (continuing the current scan). If the power of the first signal after adjustment is greater than or equal to the preset power threshold, subsequent scanning and data transmission can continue. If the power of the first signal after adjustment is still less than the preset power threshold, the system can be stopped for inspection and correction of the data transmission system. Quickly adjusting the signal receiving range of the second transceiver module may include using a preset adjustment strategy to adjust the signal receiving range of the second transceiver module at least once.

[0106] For example, if the power of the first signal is less than a preset power threshold during image scanning, the current scan can be stopped immediately, and the data transmission system can be stopped for inspection and correction so that the image scan can be restarted once the data transmission system returns to normal.

[0107] In this embodiment, by setting a power detection device at the stator end to detect the power of the first signal received by the second transceiver module, the reliability and stability of data transmission can be monitored in real time during medical image scanning, and the data transmission system can be corrected in a timely manner when data transmission abnormalities occur. This not only improves the reliability of data transmission, but also avoids users being exposed to more radiation, thereby improving scanning efficiency.

[0108] In one exemplary embodiment, such as Figure 8 As shown, the above data transmission system may further include a vibration detection device 50, which is connected to the rotating part and the controller 30 respectively; wherein, the vibration detection device 50 is used to detect the vibration information of the rotating part and send the vibration information to the controller 30; the controller 30 is also used to adjust the signal receiving range of the second transceiver module according to the vibration information.

[0109] The first transceiver module is mounted on the rotating frame of the medical imaging equipment, i.e., the rotating part, allowing it to rotate along with the frame. During rotation, frame vibration is inevitable, causing the first transceiver module to vibrate as well. When the first transceiver module vibrates, the first (optical) signal it emits may not accurately illuminate the optical signal receiving range of the second transceiver module (e.g., the central region of the optical wedge), resulting in fluctuations in the power of the received first (optical) signal. These power fluctuations not only cause unstable data transmission but may also result in power levels falling below a preset threshold, leading to incomplete data parsing and potentially serious data loss.

[0110] Based on this, in this embodiment of the application, a vibration detection device 50 is provided on the rotating part side so that the controller 30 on the stator side can adjust the signal receiving range of the second transceiver module on the stator side in real time according to the vibration information of the rotating part. This allows the second transceiver module to follow the first transceiver module in vibrating in the same way, thereby eliminating the vibration between the two. In other words, it achieves relative stillness between the second transceiver module and the first transceiver module, thus ensuring that the first (optical) signal emitted by the first transceiver module can accurately illuminate the signal receiving range of the second transceiver module. This ensures that the power of the first (optical) signal received by the second transceiver module can meet certain stability requirements, thereby improving the stability and reliability of data transmission.

[0111] For example, when the second transceiver module includes a second transceiver component and a second adjustment component, the second adjustment component can be mounted on an adjustment platform, such as a pan-tilt unit. The controller 30 can adjust the adjustment platform where the second adjustment component is located in real time based on the received vibration information of the rotating part to achieve vibration elimination. Since the first transceiver module is mounted on the rotating part, the vibration information of the rotating part can be used to characterize the vibration information of the first transceiver module. Furthermore, by collecting the vibration information of the rotating part, rather than the vibration information of the first transceiver module, the vibration acquisition device can be fixed and stationary at a preset position on the rotating part, without needing to rotate with it. This effectively avoids the influence of its own vibration during rotation, improves the accuracy of the vibration information, enhances the control accuracy of vibration elimination, and ultimately improves the stability of data transmission.

[0112] In this embodiment, a vibration detection device is installed on the rotating part side to collect vibration information of the first transceiver module during rotation. Then, the signal receiving range of the second transceiver module is adjusted according to the vibration information, so that even when vibration exists, the first signal emitted by the first transceiver module can always illuminate the effective signal receiving range of the second transceiver module, thereby eliminating vibration and ensuring the stability and reliability of the first signal received by the second transceiver module, and improving data transmission efficiency.

[0113] In an exemplary embodiment, taking optical signal transmission as an example, a data transmission system is provided, such as... Figure 9 As shown; wherein, a first optical transceiver (including optical transmitter STA-A) is mounted on a slip ring rotating part inside the rack of the medical imaging equipment, and a second optical transceiver (including optical transmitter STA-B) is mounted outside the rack and located on the rotation axis of the rack; in addition, on the optical transmission path, on the rotating part side, a rotatable optical wedge A is provided on the side of the first optical transceiver close to the second optical transceiver, and on the stator side, a rotatable optical wedge B is provided on the side of the second optical transceiver close to the first optical transceiver.

[0114] After the first optical transceiver in the rotating section performs electro-optical conversion on the received scanning data, the optical transmitter (STA-A) in the first optical transceiver emits a high-power first optical signal. The first optical signal passes through the rotatable optical wedge A and the rotatable optical wedge B and converges within the signal receiving range of the optical receiver in the second optical transceiver, so that the optical receiver in the second optical transceiver receives the first optical signal and obtains the scanning data through analysis.

[0115] After the second optical transceiver on the outer stator of the rack performs an electro-optical conversion on the received control information, the optical transmitter (STA-B) in the second optical transceiver emits a high-power second optical signal. The second optical signal passes through the rotatable optical wedge B and the rotatable optical wedge A and then converges within the signal receiving range of the optical receiver in the first optical transceiver, so that the optical receiver in the first optical transceiver receives the second optical signal and obtains the control information through analysis.

[0116] Specifically, for the first optical signal, the rotatable optical wedge A may or may not converge the first optical signal, while the rotatable optical wedge B may converge the optical path of the first optical signal, ensuring that the first optical signal is focused onto the optical receiver of the second optical transceiver. Similarly, for the second optical signal, the rotatable optical wedge B may or may not converge the second optical signal, while the rotatable optical wedge A may converge the optical path of the second optical signal, ensuring that the second optical signal is focused onto the optical receiver of the first optical transceiver.

[0117] For example, such as Figure 10 As shown, because the rotating part vibrates during rotation, the optical path cannot ideally converge at a point. Therefore, a vibration detection device can be installed on the stator inside the frame to collect the vibration information of the rotating part and send the vibration information to the controller 30 outside the frame in real time. This allows the controller 30 to adjust the rotatable optical wedge, such as optical wedge B, according to the vibration information of the rotating part, thereby eliminating vibration. This allows the rotatable optical wedge B to re-converge the optical path that has been deviated by vibration, ensuring that the optical path of the first optical signal emitted by the first optical transceiver on the rotating part during the scanning process is always converged within the signal receiving range of the optical receiver of the second optical transceiver, thus ensuring the stability of data transmission.

[0118] For example, continue to refer to Figure 10 As shown, in order to ensure the reliability of scanning data transmission, a power detection device can be set at the data receiving end outside the rack to collect the power information of the first optical signal received by the second optical transceiver. The controller 30 can fine-tune the rotatable optical wedge B according to the power information to ensure the stability of the received power at the receiving end, thereby ensuring the stability of the transmission rate. In addition, by detecting the received power, scanning can be stopped in time in case of abnormality or failure in the data transmission system, and the data transmission system can be repaired and corrected as soon as possible.

[0119] It should be noted that, due to the reversibility of the optical path, if one of the rotatable optical wedges is adjusted to ensure that the transmission of one optical signal meets the requirements, the transmission of the other optical signal will also meet the requirements.

[0120] For example, when adjusting the optical wedge, only the rotatable optical wedge A on the rotating part side can be adjusted, or only the rotatable optical wedge B on the stator side outside the frame can be adjusted, or both rotatable optical wedge A and rotatable optical wedge B can be adjusted simultaneously; the embodiments of this application do not limit this.

[0121] For example, when data transmission is based on electromagnetic waves, the electromagnetic waves can be terahertz or millimeter waves; for example, refer to Figure 11 As shown, a terahertz-based data transmission system is illustrated, comprising a terahertz transceiver and a terahertz diverter on a rotating section within the rack, and a terahertz diverter and a terahertz transceiver on an external stator; Reference Figure 12 As shown, it illustrates a millimeter-wave-based data transmission system, which includes a millimeter-wave transceiver and a rotatable millimeter-wave transceiver antenna on a rotating part inside the rack, and a rotatable millimeter-wave transceiver antenna and a millimeter-wave transceiver on an external stator of the rack.

[0122] It should be noted that the number of first transceiver modules on the rotating part can be one or more. When multiple first transceiver modules are provided on the rotating part, they can be arranged at equal intervals or at non-equal intervals; this application embodiment does not limit this. Furthermore, the data transmission system proposed in this application embodiment can realize both unidirectional and bidirectional data transmission, and can be flexibly configured according to usage requirements in actual use.

[0123] The data transmission system proposed in this application, compared to traditional carbon brush slip ring and capacitive coupling methods, innovatively places the receiver outside the rack. Without increasing the internal dimensions of the existing rack, the transmitter on the rotating part transmits the data collected inside the rotating part along the end face (axial direction) of the rotating part to the receiver outside the rack. Specifically, the transmitter is integrated into the end face of the rotating part, and its transmission path converges into a cone shape at a single point as the rotating part rotates. Because the receiver at the stator end outside the rack is not integrated inside the rack, it effectively avoids receiver vibration with the rack, improving the stability of the received signal power. Using this data transmission system, the signal transmission distance, bandwidth, and anti-interference capability of the slip ring can be effectively improved. Furthermore, it avoids the limitation of the rotating part aperture size on the processing size of traditional slip ring antennas, so that the rotating part aperture size no longer affects the slip ring bandwidth, effectively meeting the requirements for large apertures.

[0124] In one exemplary embodiment, a medical imaging device is provided, which may include the data transmission system of any of the above embodiments. Based on this, during medical image scanning, on the one hand, the data transmission system can transmit the scan data acquired by the detector in the medical imaging device to the outside, and on the other hand, external control signals can be transmitted to the medical imaging device, realizing bidirectional data transmission. The data transmission system proposed in this application can not only increase the data transmission distance between the medical imaging device and the external device, but also increase the data transmission bandwidth and data transmission rate. In addition, the data transmission system can realize bidirectional data transmission, which can avoid setting up multiple data transmission paths in the medical imaging device, thereby reducing the construction cost of the data transmission link of the medical imaging device and improving the efficiency of bidirectional data transmission.

[0125] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0126] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
