[0002] In a rotary medical device (such as a Computed Tomography (CT) rotary medical device, a Radiation Therapy (RT) device, etc.), wireless communication is achieved through a transmitting antenna and a receiving antenna to transmit the signals collected by a detector. The transmitting antenna is disposed on a slip ring disk body of a rotating gantry of the rotary medical device. Since the receiving antenna is disposed on a fixed gantry of the rotary medical device, it is necessary to process a relatively long printed circuit board antenna to form a circular structure of the transmitting antenna around the slip ring disk body to achieve communication with the receiving antenna. Moreover, when the rotary medical device is operating, the transmitting antenna on the slip ring disk body and the receiving antenna on the fixed gantry need to maintain a relative position relationship of 1 millimeter to 3 millimeters all the time to achieve communication.

[0003] However, in the traditional technology, due to the high-speed rotation of the slip ring disk body of the rotating gantry, the relative position between the transmitting antenna and the receiving antenna will change, resulting in poor signal communication quality between the two. Summary of the Invention

[0041] Please refer to Figure 1 , this application provides a wireless communication system 100, which is applied to a rotary medical device 200. The wireless communication system 100 includes a phased array transmitting unit 10 and a receiving antenna 20. The phased array transmitting unit 10 is disposed on the rotating part of the rotary medical device 200 and is used to transmit radio frequency beams. The receiving antenna 20 is disposed on the fixed part. The position of the receiving antenna 20 is within the coverage area of the radio frequency beam.

[0042] In this embodiment, the rotary medical device 200 is a device that realizes medical functions through rotational motion, such as a CT device or an RT device, etc. The rotary medical device 200 includes a rotating component. The rotating component can be understood as the rotating part of the slip ring disk body 30. The fixed component can be the fixed component of the rotary medical device 200, or the frame of the rotary medical device 200, or the support frame 50 separately provided in the rotary medical device 200.

[0043] During the scanning process of the rotary medical device 200, the phased array transmitting unit 10 transmits the signals generated by the interaction between the rays and the human tissue in the form of a radio frequency beam. The receiving antenna 20 receives the radio frequency beam transmitted by the phased array transmitting unit 10, thereby realizing the data transmission of the signals generated by the interaction between the rays and the human tissue, and realizing subsequent image reconstruction based on the transmitted data.

[0044] The phased array transmitting unit 10 is arranged on the rotating component of the rotary medical device 200 and will rotate with the rotating component. The radio frequency beam transmitted by the phased array transmitting unit 10 contains the signals generated by the interaction between the rays and the human tissue. The position of the receiving antenna 20 is within the coverage area of the radio frequency beam and can receive the radio frequency beam in real time. By setting the position of the receiving antenna 20 within the coverage area of the radio frequency beam, the receiving antenna 20 can receive the radio frequency beam in real time following the rotation of the phased array transmitting unit 10. Through the phased array transmitting unit 10 and the receiving antenna 20, the transmission and reception of the radio frequency beam are realized. Furthermore, through the wireless communication system 100 provided by the present application, the position of the receiving antenna 20 can be placed arbitrarily within the coverage area of the radio frequency beam.

[0045] Therefore, in the wireless communication system 100 provided by the present application, the radio frequency beam can be received by the receiving antenna 20 when it is quickly switched between multiple different angular directions through the phased array transmitting unit 10. Therefore, through the wireless communication system 100 provided by the present application, it is no longer limited by the requirements for the relative positions between the transmitting antenna and the receiving antenna in the traditional technology, improving the signal communication quality, so that the signals generated by the interaction between the rays and the human tissue contained in the radio frequency beam can be accurately applied to the image reconstruction in the rotary medical device 200, providing reliable and accurate data for medical diagnosis.

[0046] In one embodiment, in the rotary medical device 200, the slip ring disk body 30 is arranged on the rotating frame of the rotary medical device 200. The slip ring disk body 30 has a disk-shaped structure, surrounds the rotation center axis of the rotating frame, and rotates synchronously with the rotating frame. The slip ring disk body 30 is in close cooperation with the brush installed on the fixed frame of the rotary medical device 200, so that the brush contacts the conductive ring on the slip ring disk body 30, thereby realizing the transmission of electric energy and signals during the rotation process.

[0047] In one embodiment, the wireless communication system 100 further includes a beam control unit. The beam control unit is configured to adjust the radio frequency beam according to the motion parameters of the rotating component, so that the radio frequency beam is received by the receiving antenna 20.

[0048] In this embodiment, the motion parameters of the rotating component include one or more of a rotation angle region, the speed of the rotating component, and the acceleration of the rotating component, etc. The phased array transmitting unit 10 is disposed on the rotating component. When the rotary medical device 200 operates, the rotation of the rotating component drives the phased array transmitting unit 10 to rotate. According to the motion parameters of the rotating component, the motion condition of the rotating component can be obtained, and further the rotation condition of the phased array transmitting unit 10 can be obtained. Thus, the beam control unit can adjust the radio frequency beam in real time according to the motion parameters of the rotating component, so that it is received by the receiving antenna 20. Through the beam control unit, the radio frequency beam can be made to follow the rotating component for adjustment in real time, so that the radio frequency beam can be transmitted between the phased array transmitting unit 10 and the receiving antenna 20 in different angular directions, improving the signal communication quality.

[0049] In one embodiment, the beam control unit can also obtain the communication quality of the radio frequency beam transmitted between the phased array transmitting unit 10 and the receiving antenna 20 in real time, and adjust the radio frequency beam according to the communication quality and the communication quality threshold, so that the radio frequency beam is received by the receiving antenna 20.

[0050] In this embodiment, the communication quality of the radio frequency beam can include one or more of the signal strength, bit error rate, signal-to-noise ratio, throughput, and data transmission rate of the radio frequency beam. Furthermore, the beam control unit adjusts the radio frequency beam in real time based on the communication quality, which can further achieve high-quality signal transmission between the phased array transmitting unit 10 and the receiving antenna 20.

[0051] In one embodiment, the beam control unit includes a calibration module and a processing module. The calibration module is used to pre-store the mapping relationship between the motion parameters and the corresponding beam parameters. The processing module is used to call the mapping relationship according to the motion parameters of the rotating component to determine the beam parameters, so as to adjust the pointing of the radio frequency beam.

[0052] In this embodiment, the phased array transmitting unit 10 is disposed on the rotating member and has a fixed relative positional relationship with the rotating member. When the rotary medical device 200 operates, the rotating member drives the phased array transmitting unit 10 to rotate. Furthermore, there is a corresponding relationship between the motion parameters of the phased array transmitting unit 10 and the rotating member. When calibrating the phased array transmitting unit 10 and the receiving antenna 20 in the wireless communication system 100, a mapping relationship between the motion parameters and the corresponding beam parameters is generated. The beam parameters can be the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 or / and the beam parameters of the radio frequency beam received by the receiving antenna 20.

[0053] The mapping relationship between the pre-stored motion parameters and the corresponding beam parameters in the calibration module characterizes the calibration relationship between the phased array transmitting unit 10 and the receiving antenna 20, and can ensure that during the rotation of the phased array transmitting unit 10 following the rotating member, high-quality wireless communication is performed with the receiving antenna 20 in real time. Thus, the processing module can determine the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 or / and the beam parameters of the radio frequency beam received by the receiving antenna 20 by calling the mapping relationship according to the motion parameters of the rotating member, so that the radio frequency beams transmitted by the phased array transmitting unit 10 from different angular directions can be received by the receiving antenna 20, improving the signal communication quality, and enabling the signals generated by the interaction between the rays included in the radio frequency beam and the human tissue to be accurately applied to the image reconstruction in the rotary medical device 200.

[0054] In one embodiment, the mapping relationship includes the mapping relationship between the rotation angle region and the beam parameters. The rotation positions of the rotating member are divided into multiple ones. For example, the rotation angle of the rotating member for one week is 360°, and a rotation position is set every 30° rotation angle, and the rotation positions of the rotating member are divided into 12. Or, in one embodiment, the rotation positions of the rotating member are divided into 16 or more, and the specific number can be set according to the actual application scenario, which is not limited in this application. Or, in one embodiment, the rotation positions of the rotating member are evenly or unevenly divided into multiple ones.

[0055] The phased array transmitting unit 10 is disposed on the rotating member. When the real-time rotation position of the rotating member is determined to be one of 12 or one of 16 or one of more, it can be known which transmitting position the phased array transmitting unit 10 is located at. The signals of the phased array transmitting unit 10 and each antenna in the receiving antenna 20 are scanned and positioned to confirm the signal transmission direction, so as to satisfy the communication signals with the bit error rate requirement, and thus the calibrated beam parameters, such as the transmission phase information and the reception phase information, are obtained. The transmission phase information is used to regulate the phased array transmission phase. The reception phase information is used to regulate the phased array reception phase. Thus, different rotation positions in the motion parameters correspond to different beam parameters.

[0056] Please refer to Figure 2 With Figure 3 , in one embodiment, the rotation angle region can be understood as the specific angle range where the phased array transmitting unit 10 is located on the rotating component. For example Figure 2 With Figure 3 the first angle region, the second angle region, the third angle region, or the fourth angle region shown in

[0057] Similarly, in one embodiment, the mapping relationship includes the mapping relationship between the speed of the rotating component and the beam parameters. The motion parameter can also be the speed of the rotating component. The motion parameter characterizes the motion condition of the rotating component, and thus can characterize the rotation condition of the phased array transmitting unit 10. Based on the communication signal that meets the bit error rate requirement, the calibration module establishes the mapping relationship between the motion parameter of the rotating component and the corresponding beam parameters during the calibration process. During the rotation of the rotating component, the mapping relationship between the speed of the rotating component and the corresponding beam parameters is established. Thus, different speeds of the rotating component in the motion parameter correspond to different beam parameters

[0058] Similarly, in one embodiment, the mapping relationship includes the mapping relationship between the acceleration of the rotating component and the beam parameters. The motion parameter can also be the acceleration of the rotating component. During the rotation of the rotating component, the mapping relationship between the acceleration of the rotating component and the corresponding beam parameters is established. Thus, when the acceleration of the rotating component in the motion parameter changes, different corresponding beam parameters change accordingly. Thus, according to the motion parameter of the rotating component, the processing module can call the mapping relationship to determine the beam parameters. According to the beam parameters, the pointing of the RF beam can be adjusted to enable high-quality transmission of the RF beam between the phased array transmitting unit 10 and the receiving antenna 20

[0059] In one embodiment, the processing module is connected to the phased array transmitting unit 10, calls the mapping relationship according to the motion parameter of the rotating component, determines the beam parameters of the RF beam emitted by the phased array transmitting unit 10, and adjusts the pointing of the RF beam emitted by the phased array transmitting unit 10

[0060] In one embodiment, the processing module is connected to the receiving antenna 20, calls the mapping relationship according to the motion parameters of the rotating component, determines the beam parameters of the radio frequency beam received by the receiving antenna 20, so as to adjust the receiving direction of the receiving antenna 20.

[0061] In one embodiment, the processing module is respectively connected to the phased array transmitting unit 10 and the receiving antenna 20, calls the mapping relationship according to the motion parameters of the rotating component, determines the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 and the beam parameters of the radio frequency beam received by the receiving antenna 20, so as to adjust the transmitting direction of the radio frequency beam transmitted by the phased array transmitting unit 10 and the receiving direction of the receiving antenna 20. By simultaneously adjusting the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 and the beam parameters of the radio frequency beam received by the receiving antenna 20, the phased array transmitting phase of the phased array transmitting unit 10 and the phased array receiving phase of the receiving antenna 20 can be adjusted in real time and simultaneously, so that the phased array transmitting unit 10 and the receiving antenna 20 can follow and adjust each other, no longer limited by the position of the phased array transmitting unit 10, and no longer limited by the position of the receiving antenna 20.

[0062] In one embodiment, the wireless communication system 100 further includes a slide rail, and the support frame 50 is arranged on the slide rail, which can realize real-time position adjustment so that the position of the receiving antenna 20 can be moved arbitrarily. Furthermore, through the slide rail, the relative position between the support frame 50 and the rotating component can be unrestricted and can be set according to the actual application scenario, which is convenient to realize the movement and fixation of the position.

[0063] In one embodiment, the mapping relationship can exist in the form of a database, and the processing module directly calls the mapping relationship in the database to realize the adjustment of the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 or / and the beam parameters of the radio frequency beam received by the receiving antenna 20.

[0064] In one embodiment, the mapping relationship can exist in the form of a learning model. The learning model is used as the carrier of the mapping relationship and continuously learns the mapping relationship between the motion parameters and the beam parameters. The processing module calls the mapping relationship established by the learning model to realize the adjustment of the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 or / and the beam parameters of the radio frequency beam received by the receiving antenna 20.

[0065] In one embodiment, there is a mapping relationship between the time parameters pre-stored in the calibration module and the corresponding beam parameters. The processing module calls the mapping relationship according to the current time to determine the beam parameters for adjusting the pointing of the radio frequency beam. Taking the time when the rotating component starts to rotate as the initial time, a mapping relationship between the time parameters and the beam parameters is established. The processing module calls the corresponding beam parameters in the mapping relationship according to the current time to adjust the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 and / or the beam parameters of the radio frequency beam received by the receiving antenna 20.

[0066] In one embodiment, the mapping relationship between the motion parameters pre-stored in the calibration module and the corresponding beam parameters further includes time parameters. During the calibration process between the phased array transmitting unit 10 and the receiving antenna 20, by adding time parameters, a mapping relationship between the time parameters, the motion parameters, and the beam parameters can be established with the time when the rotating component starts to rotate as the initial time. The calibration module pre-stores the mapping relationship between the motion parameters, the time parameters, and the beam parameters.

[0067] The processing module calls the corresponding beam parameters in the mapping relationship according to the current time and the motion parameters to adjust the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 and / or the beam parameters of the radio frequency beam received by the receiving antenna 20. By incorporating time parameters, the relationship nodes in the mapping relationship are increased, and the corresponding beam parameters can be called based on the dual reference of the time parameters and the motion parameters, thereby enabling more accurate adjustment of the beam parameters of the radio frequency beam transmitted by the phased array transmitting unit 10 and / or the beam parameters of the radio frequency beam received by the receiving antenna 20.

[0068] In one embodiment, the wireless communication system 100 further includes a synchronization module 40. The synchronization module 40 is used to obtain the real-time motion parameters of the rotating component and transmit the real-time motion parameters to the beam control unit.

[0069] In this embodiment, the synchronization module 40 can be connected to the rotating component by wire or wirelessly to actively obtain the real-time motion parameters of the rotating component in real time and transmit the real-time motion parameters to the beam control unit. In one embodiment, the synchronization module 40 is connected to the drive motor of the rotating component. The drive motor drives the rotating component to rotate, and thus the rotation angle of the rotating component can be calculated based on the rotation speed of the drive motor, and the position of the rotating component can be known in real time.

[0070] The rotating component can also actively send the real-time motion parameters to the synchronization module 40 in real time, and the synchronization module 40 transmits the real-time motion parameters to the beam control unit.

[0071] In one embodiment, the beam control unit can also be integrated with the synchronization module 40 into the same unit.

[0072] Please refer to Figure 4 In one embodiment, the phased array transmitting unit 10 can be understood as an array composed of multiple transmitting antennas 110. By adjusting the phases of the multiple transmitting antennas 110 in the phased array transmitting unit 10, the mutual combination between different transmitting phases can be achieved, and the radio frequency beam can be transmitted from different angles. The number of phased array transmitting units 10 is not limited, and can be one, two, three, etc.

[0073] In one embodiment, the number of receiving antennas 20 is not limited, and can be one, two, three, etc. Multiple receiving antennas 20 can form a phased array receiving unit and be arranged in an array form. By adjusting the phases of the multiple receiving antennas, the mutual combination between different receiving phases can be achieved, and the radio frequency beam can be received from different angles. By receiving the radio frequency beam transmitted by the phased array transmitting unit 10 through the multiple receiving antennas 20, the transmission of multiple radio frequency beams can be achieved simultaneously, and parallel communication can be realized. Thus, through the wireless communication system 100 provided by the present application, the communication capacity can be significantly improved, the high-speed transmission of multiple radio frequency beams can be realized, the transmission time of the signal data generated by the interaction between the rays detected by the detector in the rotary medical device 200 and the human tissue can be saved, the signal transmission efficiency can be improved, and the detection time of the rotary medical device 200 can be saved.

[0074] In one embodiment, the operating frequency band or operating time slot of at least one phased array transmitting unit 10 is independent.

[0075] In this embodiment, the operating frequency band or operating time slot of the phased array transmitting unit 10 is independent, and frequency division multiplexing or time division multiplexing can be achieved to avoid mutual interference, so that the signals are reasonably divided and arranged in the frequency and time dimensions to improve the transmission efficiency and resource utilization rate between the phased array transmitting unit 10 and the receiving antenna 20.
