[0002] Currently, ultrasound equipment primarily connects the ultrasound unit and probe via wired cables. To prevent signal interference during communication, these cables typically consist of multiple coaxial cables, making maintenance of ultrasound equipment somewhat cumbersome. With the continuous development of wireless communication technology, many medical equipment manufacturers have also incorporated wireless communication into their ultrasound equipment, significantly simplifying maintenance.

[0003] In related technologies, when using wireless communication technology in ultrasound equipment, data is usually acquired through the signal channel built into the ultrasound probe, and the acquired data is transmitted to the ultrasound host wirelessly (e.g., via WIFI wireless communication, Wireless Fidelity, wireless network module, or Bluetooth, etc.) to realize data transmission between the ultrasound probe and the ultrasound host.

[0004] However, as the number of signal channels built into the ultrasound probe continues to increase, the amount of data transmitted to the ultrasound host also gradually increases. Using traditional wireless methods for communication data transmission makes it difficult to guarantee the communication rate during the data transmission process. Summary of the Invention

[0047] 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.

[0048] Currently, the connection between the ultrasound host and the ultrasound probe is mainly via wired cable. To prevent signal interference, the connecting cable consists of many coaxial cables, making it thick and heavy. Furthermore, a host often carries multiple probes, and the probe cables easily become tangled, causing inconvenience for medical staff. Prolonged use can also lead to wear and tear and potentially contaminate sterile areas used in surgical procedures. With the rapid development of wireless communication technology, wireless ultrasound probes have become possible. Wireless connection between the probe and the ultrasound host greatly facilitates medical staff; however, it also brings some problems. Low-end medical ultrasound probes on the market are mainly 32 or 64 channels, mid-to-high-end probes are mainly 64 channels with some having 128 channels, and high-end probes are mainly 128 channels, or even exceed 192 channels. As the number of probe channels increases, the amount of data acquired by the probe also increases, requiring a higher communication speed between the probe and the ultrasound host. For example, a 64-channel probe generates 64 * 840 = 52.5 Gbps of data (ADC sampling rate 60 MSPS, sampling quantization bit depth 14 bits, so the single-channel data communication rate is 60 * 14 = 840 Mbps). Even after signal compression, the amount of data to be uploaded to the ultrasound host is still considerable. For mid-range and high-end ultrasound probes, the data communication volume is even greater, so the communication rates of mainstream wireless communication methods cannot meet the requirements. A comparison of the communication rates of mainstream short-range wireless communications such as WIFI, BT, Wireless USB, and UWB is shown in Table 1 below. The rates of these mainstream wireless communications are all limited to some extent.

[0049] Table 1

[0050] Wireless technology Communication rate Explanation WiFi Up to 3.5Gbps WiFi6 theoretically up to 9.6Gbps BT Up to 1Mbps / Wireless USB 480Mbps Up to 1Gbps UWB Several hundred Mbps Up to 1Gbps

[0051] Therefore, it is evident that traditional wireless methods for data transmission struggle to guarantee communication speeds during data transmission. Consequently, this application provides a wireless communication system and method to address the aforementioned technical problems. The technical solutions of this application's embodiments are described below.

[0052] In one embodiment, a wireless communication system is provided, see [link to relevant documentation]. Figure 1 As shown, the wireless communication system may include: an ultrasonic probe, multiple wireless communication host terminals, an ultrasonic host, and multiple laser transceivers. The ultrasonic probe is used to acquire ultrasonic data of the object being tested. The multiple wireless communication host terminals are communicatively connected to the ultrasonic probe. The ultrasonic host is electrically connected to the multiple wireless communication host terminals. Multiple laser transceivers (not shown in the figure) are respectively disposed inside the ultrasonic probe and the multiple wireless communication host terminals, and the wireless communication host terminals and the ultrasonic probe communicate via the laser transceivers.

[0053] The object being tested can be all parts of a human or animal body, or one or more parts of a human or animal body.

[0054] The shape of the ultrasound probe can be set according to the actual situation, as long as the shape of the ultrasound probe does not obstruct its wireless laser optical window and is convenient for medical staff to operate. For example, it can be a gun-shaped ultrasound probe, an elliptical ultrasound probe, etc. This embodiment mainly uses a gun-shaped ultrasound probe, which not only facilitates the operation of medical staff, but also makes it easier to track and aim the wireless laser emitted by the ultrasound probe.

[0055] The form of the wireless communication host can also be set according to the actual situation, such as a terminal with laser signal transceiver function. The number of wireless communication host terminals can also be set according to the actual situation, such as one, two, three, etc. In addition, the ultrasonic probe can be a wireless ultrasonic probe, which can achieve laser communication with each wireless communication host terminal wirelessly.

[0056] Each laser transceiver includes a laser transmitter and a laser receiver, forming a pair. Each transceiver can have the laser transmitter located inside the ultrasonic probe and the laser receiver inside the wireless communication host, or vice versa. Alternatively, both the ultrasonic probe and the wireless communication host can contain laser transmitters and receivers, as long as the laser transceivers in both devices are paired, enabling laser wireless communication between them. The number of laser transceivers can be set according to actual needs, such as one, two, three, etc., as long as the total number matches the number of wireless communication host devices—that is, each wireless communication host device includes a laser transceiver.

[0057] The form of the ultrasound host can also be set according to the actual situation, such as a tablet, mobile terminal, laptop or other computer device.

[0058] In addition, the wireless communication host and the ultrasound host can be electrically connected, for example, through a communication cable. Furthermore, when making the electrical connection between the wireless communication host and the ultrasound host, the wireless communication host can also be fixed with a bracket. This facilitates alignment between the wireless communication host and the ultrasound probe, enabling rapid laser wireless communication and improving data transmission efficiency.

[0059] As described above, in this embodiment of the application, by installing a laser transceiver device inside the ultrasound probe and the wireless communication host, the ultrasound probe can transmit a large amount of ultrasound data to the wireless communication host via laser wireless communication. This ensures that the communication rate of the transmitted data is not limited. Then, the wireless communication host can transmit the received ultrasound data to the ultrasound host, realizing the transmission of ultrasound data between the ultrasound probe and the ultrasound host. This improves the communication rate of data transmission between the ultrasound probe and the ultrasound host, enabling the wireless transmission of data from mid-to-high-end ultrasound probes.

[0060] The aforementioned wireless communication system includes an ultrasonic probe for acquiring ultrasonic data of the object being tested; multiple wireless communication host terminals communicatively connected to the ultrasonic probe; an ultrasonic host electrically connected to the multiple wireless communication host terminals; and multiple laser transceivers, respectively housed within the ultrasonic probe and the multiple wireless communication host terminals. The wireless communication host terminals and the ultrasonic probe communicate via these laser transceivers. This wireless communication system enables laser wireless communication between the ultrasonic probe and the ultrasonic host. Compared to traditional wireless communication methods, this system offers greater communication capacity, does not occupy radio spectrum resources, and does not interfere with the normal operation of the ultrasonic probe's internal circuitry. Therefore, it can achieve large-scale data transmission between the ultrasonic probe and the ultrasonic host, ensuring the communication rate during data transmission. Furthermore, this system can be used indoors, eliminating issues such as changes in the beam transmission path and laser communication signal attenuation caused by weather or other environmental factors between the ultrasonic probe and the ultrasonic host. This further guarantees the communication rate during data transmission between the ultrasonic probe and the ultrasonic host.

[0061] The above embodiments briefly describe the shape and structure of the ultrasonic probe. In another embodiment, a specific structure of the ultrasonic probe is provided below. (See attached image.) Figure 2 As shown, the external structure of the ultrasonic probe consists of a charging port, a power button, control buttons, a laser communication optical window, a probe transducer array, and internal transceiver / signal processing circuitry.

[0062] The charging port is used to connect the charging cable to charge the internal battery of the ultrasonic probe. The power button is used to turn the ultrasonic probe's power on and off. The control buttons are used for basic operation control of the ultrasonic probe. The laser communication optical window is mainly used for signal transmission and reception during laser wireless communication with the wireless communication host. The probe transducer array is used to convert electromagnetic waves into mechanical energy (acoustic energy).

[0063] Furthermore, the ultrasound probe may also include:

[0064] Power Management Unit: Provides power for battery charging management and the implementation of all electrical functions of the probe;

[0065] Matching circuit: Provides short-range radio communication functionality, enabling identification between the ultrasound probe and the ultrasound host, as well as positioning via RSSI. This short-range radio communication technology is not limited to BT, UWB, Zigbee, WiFi, or other technologies.

[0066] Wireless laser communication unit: Provides a wireless communication channel between ultrasound hosts, encoding and modulating the ultrasound echoes acquired by the AFE and transmitting them in laser form. Conversely, it receives modulated laser signals sent by the wireless communication host, demodulates them, and transmits beacon light signals.

[0067] Signal processing unit: realizes transmit beamforming, echo signal preamplification and AFE control, receive beam processing, signal preprocessing, etc.

[0068] Transmitting unit: Provides high-voltage excitation signals to drive the transducer, not limited to pulse signals and continuous wave signals;

[0069] AFE: Ultrasonic echo receiver front end, including LNA, TGC, LPF, ADC, etc.;

[0070] T / R: Ultrasonic transceiver switch.

[0071] Based on this, the aforementioned ultrasonic probe is also equipped with a beacon light emitting device, and the aforementioned wireless communication host also includes a beacon light detection device. The wireless communication host detects the beacon light through the beacon light detection device to achieve tracking of the ultrasonic probe. Here, the beacon light provides the wireless communication host with a beacon for capture, tracking, and aiming, ensuring that the beacon light detection device on the wireless communication host is always aligned with the emission field of the beacon light emitting device, thereby improving the accuracy of data transmission between the ultrasonic probe and the wireless communication host.

[0072] Further, please see here. Figure 3 As shown, the transmitting part of the ultrasonic probe (i.e., the wireless laser communication probe end in the figure) may include a laser, a laser driver, a probe signal processing unit, an optical modulator, a signal conditioning unit (i.e., the signal processing unit above), and an optical transmitting antenna (i.e., the transmitting unit above and the wireless laser communication unit); the receiving part may include an optical receiving antenna, a photodetector, a signal conditioning and amplification unit, a signal demodulation unit, and may also include a beacon light for emitting beacon light.

[0073] The transmitting part of the wireless communication host can include a laser, a laser driver, an optical modulator, a signal conditioning unit, and an optical transmitting antenna; the receiving part can include an optical receiving antenna, a photodetector signal, a conditioning and amplification unit, and a signal demodulation unit. It can also include a tracking and aiming unit for tracking and aligning the ultrasonic probe based on the beacon light emitted by the ultrasonic probe, and a communication interface for data communication with the ultrasonic host.

[0074] It should be noted that, Figure 3 This is merely an example and does not affect the substantive content of the embodiments of this application.

[0075] Among them, see Figure 4 As shown, the tracking and aiming unit includes a lens, a filter, a high-frequency vision camera, a visual signal processing unit, and a tracking and aiming gimbal. The visual signal processing unit calculates the trajectory of the tracking and aiming gimbal in real time based on the position of the beacon (usually an LED with a large field of view) detected by the high-frequency vision camera. When the distance between the beacon light spot position and the center of the field of view of the target wireless communication host meets the set conditions, the center of the field of view of the target wireless communication host is the center of the field of view (or center position) of the high-frequency vision camera. At this time, it can be determined that the target wireless communication host is aligned with the ultrasonic probe. At the same time, the gimbal motor is controlled to drive the wireless communication host to scan and complete the tracking and aiming. When the captured beacon light spot is in the center of the camera, the wireless communication host is the ultrasonic probe end for aiming at the wireless laser communication.

[0076] The distance between the beacon light spot position and the center of the field of view of the target wireless communication host meets the set condition, meaning that the spot position can be in the vicinity of the center position of the high-frequency vision camera. For example, the spot position is within a certain distance from the center position of the high-frequency vision camera, such as 0.1mm, 0.5mm, etc. Preferably, the target wireless communication host is aligned with the ultrasonic probe when the spot position is at the exact center of the high-frequency vision camera.

[0077] The specific tracking and aiming process is as follows: After the ultrasound probe is activated, it immediately emits a beacon light. The wireless communication host module scans the beacon light area. Once the beacon light is detected, acquisition is complete, and the tracking and aiming unit immediately scans and tracks the wireless communication end. When the beacon light spot is located at the center of the high-frequency camera, an audible and visual alert signal is sent to the ultrasound host via the communication cable, indicating to medical staff that the communication optical path has been established and ultrasound detection can be performed. If the wireless communication host fails to detect the beacon light after scanning and tracking for a period of time, an audible and visual alarm signal is issued, reminding medical staff to adjust the angle of the fixation bracket to adjust the position of the wireless communication host so that the wireless communication host can detect the beacon light.

[0078] The following describes the communication process between the ultrasonic probe and the wireless communication host. During communication, after the digital signal to be transmitted is modulated into an electrical signal, the signal can be input into an optical modulator and modulated onto the laser beam generated by the laser. The laser carrier carrying the modulation information is then transmitted through an optical transmitting antenna. The optical receiving antenna receives the signal. After receiving the modulated laser signal, the electrical signal is extracted by a photodetector, and then demodulated by a conditioning and amplification circuit to recover the original digital signal and restore the original information.

[0079] In addition, both the aforementioned optical transmitting antenna and optical receiving antenna can be made of lenses. The transmitting antenna transforms a laser beam with a very small cross-section into a laser beam with a larger cross-section, making it easier for the receiving antenna to adjust its orientation and receive signals. The optical receiving antenna can receive a laser beam with a large area and focus the laser beam into a smaller spot.

[0080] In this embodiment, the ultrasonic probe is also equipped with a beacon light emitting device, and the wireless communication host also includes a beacon light detection device. The wireless communication host detects the beacon light through the beacon light detection device to track the ultrasonic probe. This ensures that the beacon light detection device on the wireless communication host is always aligned with the emission field of the beacon light emitting device, improving the accuracy of data transmission between the ultrasonic probe and the wireless communication host.

[0081] The above embodiments mention that the wireless communication system includes multiple wireless communication host terminals. However, the arrangement and field of view of each wireless communication host terminal are not described. Therefore, another embodiment is provided below, which mainly describes the arrangement and field of view of each wireless communication host terminal.

[0082] In this embodiment, multiple wireless communication host terminals are positioned above the object being detected, and are circumferentially distributed with the object being detected as the center. Optionally, the detection field of view of the multiple wireless communication host terminals covers the scanning field of view of the object being detected; each wireless communication host terminal has a different detection field of view.

[0083] Please see details. Figure 5 As shown, the subject is placed on a hospital bed. The ultrasound imaging equipment can be equipped with multiple ultrasound probes, which can be of different types. During the examination, one ultrasound probe can be used at a time to acquire ultrasound data, depending on the situation. Alternatively, different types of ultrasound probes can be switched as needed. Simultaneously, multiple wireless communication terminals are positioned above each ultrasound probe, i.e., above the subject, arranged in a circular or square pattern around the subject to obtain omnidirectional ultrasound data. The number of wireless communication terminals is the same as the number of ultrasound probes.

[0084] Regarding the detection field of view of each wireless communication host, the detection field of view is different for each wireless communication host. That is, each wireless communication host receives ultrasound data from different scanning field of view of the object being detected. For example... Figure 5 The detection field of view of wireless communication host I is (c+a / 2)°, that of wireless communication host II is (c+b / 2)°, and that of wireless communication host III is (a / 2+b / 2)°. Furthermore, the detection field of view of all wireless communication host terminals is sufficient to cover the entire scanning field of view of the object being examined. This means that all wireless communication host terminals can detect the ultrasound data of the object being examined within the entire scanning field of view. This avoids the problem of incomplete ultrasound data due to missing ultrasound data, which would affect the final image reconstruction results.

[0085] Of course, in order to improve the efficiency and accuracy of the ultrasonic probe in capturing ultrasonic data at the wireless communication host, the field of view (FOV) of the wireless communication host can be increased so that the detection angle range of the wireless communication host covers the scanning field of view of the object being detected.

[0086] In this embodiment, multiple wireless communication host terminals are positioned above the object being tested and distributed circumferentially around the object, thus obtaining omnidirectional ultrasound data of the object. Furthermore, the detection angles of the multiple wireless communication host terminals cover the scanning field of view of the object, and each wireless communication host terminal has a different detection angle, thereby obtaining complete ultrasound data of the object and improving the quality of the reconstructed image obtained from the ultrasound data.

[0087] The above embodiments mention that the wireless communication host can detect the beacon light emitted by the ultrasound probe and track and align the ultrasound probe based on the beacon light. Another embodiment is provided below, mainly describing the specific process by which the ultrasound host controls the establishment of a communication connection between the wireless communication host and the ultrasound probe after each wireless communication host detects the beacon light emitted by the ultrasound probe. Based on the above embodiments, the ultrasound host may include an intensity acquisition module for acquiring the light intensity of the beacon light signal detected by each wireless communication host; and an intensity sorting module for sorting the light intensities and determining the target wireless communication host from among multiple wireless communication hosts based on the sorting results, so as to establish a communication connection between the target wireless communication host and the ultrasound probe.

[0088] In this system, after each wireless communication host detects the beacon light signal emitted by the ultrasound probe, it sends the detected beacon light signal to the intensity acquisition module of the ultrasound host. This intensity acquisition module obtains the intensity of each beacon light signal from the received signals and then sends the intensities to the intensity sorting module for sorting. Optionally, the intensity sorting module is specifically used to sort the light intensities to obtain an intensity sorting result; obtain the maximum light intensity from the intensity sorting result and the wireless communication host corresponding to the maximum light intensity; and determine the wireless communication host corresponding to the maximum light intensity as the target wireless communication host.

[0089] When the intensity sorting module sorts the intensities of each beacon light signal, it can sort them from smallest to largest or from largest to smallest; either way, a sorting result can be obtained. If sorted from smallest to largest, the last beacon light intensity in the sorted result is the largest beacon light intensity; if sorted from largest to smallest, the first beacon light intensity in the sorted result is the largest beacon light intensity. In short, the largest beacon light intensity can be determined, and the corresponding wireless communication host can be obtained and used as the target wireless communication host. At this point, a communication connection can be established between the target wireless communication host and the ultrasound probe. The data transmission efficiency and accuracy of the wireless communication host and the ultrasound probe established in this way are the highest, thus ensuring the accuracy of the transmitted data.

[0090] Of course, the above can also involve a single ultrasound probe simultaneously establishing connections with multiple wireless communication hosts. In one possible implementation, the ultrasound probe may have multiple signal transceiver channels. When the ultrasound probe transmits and receives data with multiple wireless communication hosts, it can do so through these multiple signal transceiver channels. Alternatively, the ultrasound probe may have only one signal transceiver channel. When the ultrasound probe transmits and receives data with multiple wireless communication hosts, it can be controlled to use this single channel to transmit and receive data with the multiple wireless communication hosts in a time-division manner. For example, the ultrasound probe might transmit and receive data with the first wireless communication host at a first moment, and with the second wireless communication host at a second moment, and so on.

[0091] In this embodiment, the intensity of the beacon light signal detected by each wireless communication host is acquired by the intensity acquisition module of the ultrasound host, and the intensity sorting module of the ultrasound host sorts the light intensities. Based on the sorting results, the target wireless communication host for establishing a communication connection with the ultrasound probe is determined. This ensures the highest efficiency and accuracy of data transmission between the wireless communication host and the ultrasound probe, thereby guaranteeing the accuracy of the transmitted data. Furthermore, the intensity sorting module can identify the wireless communication host corresponding to the highest light intensity in the intensity sorting results as the target wireless communication host. This process is relatively simple, thus improving the efficiency of identifying the target wireless communication host and consequently enhancing the communication efficiency between the target wireless communication host and the ultrasound probe.

[0092] The above Figures 1-5 The embodiments illustrate the structure of the wireless communication system and the specific laser wireless communication process. The technical solution of this application will be further described below from the perspective of wireless communication methods.

[0093] In one embodiment, such as Figure 6 As shown, a wireless communication method is provided, which is applied to... Figures 1-5 Taking a wireless communication system as an example, the method may include the following steps:

[0094] S602, the ultrasonic probe acquires ultrasonic data of the object being tested.

[0095] S604, the ultrasound probe communicates with multiple wireless communication host terminals through multiple laser transceivers to send ultrasound data to the wireless communication host terminals.

[0096] S606, the ultrasound host transmits data with multiple wireless communication host terminals and receives ultrasound data sent by multiple wireless communication host terminals.

[0097] In this embodiment, the explanation of steps S602-S606 can be found in the explanation of the wireless communication system described above, and will not be repeated here.

[0098] The aforementioned wireless communication method utilizes a wireless communication system comprising an ultrasonic probe for acquiring ultrasonic data of the object being tested; multiple wireless communication host terminals connected to the ultrasonic probe; an ultrasonic host electrically connected to the multiple wireless communication host terminals; and multiple laser transceivers, respectively housed within the ultrasonic probe and the multiple wireless communication host terminals. The wireless communication host terminals and the ultrasonic probe communicate via these laser transceivers. This wireless communication system enables laser wireless communication between the ultrasonic probe and the ultrasonic host. Compared to traditional wireless communication methods, this system offers greater communication capacity, does not occupy radio spectrum resources, and does not interfere with the normal operation of the ultrasonic probe's internal circuitry. Therefore, it can achieve large-scale data transmission between the ultrasonic probe and the ultrasonic host, ensuring the communication rate during data transmission. Furthermore, this system can be used indoors, eliminating issues such as changes in the beam transmission path and laser communication signal attenuation caused by weather or other environmental factors, further guaranteeing the communication rate during data transmission between the ultrasonic probe and the ultrasonic host.

[0099] In another embodiment, such as Figure 7 As shown, another wireless communication method is provided. Based on the above embodiments, this method may further include the following steps:

[0100] S702, acquire the light intensity of the beacon light signal detected by each wireless communication host.

[0101] S704 sorts the light intensities and determines the target wireless communication host from multiple wireless communication host terminals based on the sorting results, so that the ultrasound host can establish a communication connection with the ultrasound probe through the target wireless communication host terminal.

[0102] Optionally, S704 may include: sorting the light intensities to obtain a sorting result; obtaining the maximum light intensity from the intensity sorting result and obtaining the wireless communication host corresponding to the maximum light intensity; and determining the wireless communication host corresponding to the maximum light intensity as the target wireless communication host.

[0103] In this embodiment, the explanation of steps S702-S704 can be found in the explanation of the wireless communication system described above, and will not be repeated here.

[0104] In this embodiment, the light intensity of the beacon light signal detected by each wireless communication host is acquired and sorted. Based on the sorting result, the target wireless communication host for establishing a communication connection with the ultrasound probe is determined. This ensures the highest efficiency and accuracy of data transmission between the wireless communication host and the ultrasound probe, thereby guaranteeing the accuracy of the transmitted data. Furthermore, the wireless communication host corresponding to the highest light intensity in the intensity sorting result can also be identified as the target wireless communication host. This process is relatively simple, thus improving the efficiency of identifying the target wireless communication host and consequently enhancing the communication efficiency between the target wireless communication host and the ultrasound probe.

[0105] In another embodiment, another wireless communication method is provided, which, based on the above embodiments, may further include the following step A:

[0106] Step A: The target wireless communication host aligns itself with the ultrasonic probe based on the detected beacon light signal.

[0107] Specifically, during alignment, optionally, the position of the beacon light signal spot can be tracked. When the distance between the spot position and the center of the field of view of the target wireless communication host meets a set condition, the alignment of the target wireless communication host with the ultrasonic probe is determined. The set condition here is the same as that in the wireless communication system described above, that is, the target wireless communication host can determine the alignment of the target wireless communication host with the ultrasonic probe by tracking the position of the beacon light signal spot. Preferably, when the spot position is located at the center of the high-frequency vision camera, the alignment of the target wireless communication host with the ultrasonic probe can be determined, and a communication connection between the two can be established.

[0108] In this embodiment, the target wireless communication host aligns itself with the ultrasonic probe using the detected beacon light signal. This accurately establishes a communication connection with the ultrasonic probe, improving the accuracy of subsequent data transmission. Furthermore, alignment can be determined by the position of the light spot at the center of the camera. This process is relatively simple and intuitive, thus reducing the complexity of the alignment process and improving the efficiency of establishing a communication connection.

[0109] In another embodiment, another wireless communication method is provided, which, based on the above embodiments, may further include the following step B:

[0110] Step B: The target wireless communication host outputs a first prompt message to the ultrasound host; the first prompt message is used to indicate that the laser wireless communication link between the ultrasound probe and the target wireless communication host has been established.

[0111] In this step, after the target wireless communication host is aligned with the ultrasound probe and a communication connection is established, a prompt message can be sent to the ultrasound host to indicate to medical staff that the communication optical path has been established and ultrasound detection can be performed, so that medical staff can quickly detect the object being tested.

[0112] In addition, if the wireless communication host fails to detect the beacon light after scanning and tracking for a period of time, it will issue an audible and visual alarm signal to remind medical staff to adjust the angle of the fixation bracket, thereby adjusting the position of the wireless communication host so that it can detect the beacon light. This can also improve the accuracy and efficiency of detecting the object being examined.

[0113] In this embodiment, after the target wireless communication host is aligned with the ultrasound probe and a communication connection is established, the target wireless communication host can send a prompt message to the ultrasound host, which makes it easier for medical staff to quickly detect the object being tested.
