[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0061] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0063] The ultrasound probe is called the eyes of the ultrasound machine. Its performance directly affects the ultrasound imaging effect and the doctor's diagnosis results. Therefore, each probe manufacturer and user will test and control the probe performance indicators and issue a probe qualification report. The evaluation indicators of the ultrasound probe mainly include acoustic performance indicators such as the center frequency and relative bandwidth of the ultrasound probe. At present, the probe detection system mainly purchases a complete set of software and hardware systems, which is expensive to purchase. Secondly, the expansion of new probe models requires a separate charge and a long development cycle. In addition, the probe detection system can only be controlled manually, and it is necessary to manually judge whether the test results meet the index requirements. It takes a long time for testers to replace new probes, which is not suitable for mass production testing on the production line.

[0064] In response to the above problems, an embodiment of the present application provides a detection method and system for an ultrasonic probe, wherein the terminal device can control the mobile control component to move the target probe to the corresponding detection position according to the probe type of the target probe to be detected. A signal is transmitted and received at the detection position, and the test parameters of the target probe are determined based on the reflected signal, thereby determining the detection result of the target probe. In the present application, there is no need for the tester to manually move the target probe to the test position. The target probe only needs to be fixed at a fixed position of the mobile control component. The terminal device automatically moves to the detection position according to the type of probe, and then performs detection of the target probe. This method is simple to operate and is suitable for mass production of production line probes.

[0065] The following describes the application scenarios of the detection method of the ultrasonic probe provided in the embodiment of the present application in conjunction with the accompanying drawings.

[0066] The present application embodiment provides a detection system of an ultrasonic probe, see Figure 1 The ultrasonic probe detection system includes a terminal device 100 , a mobile control component 200 , an ultrasonic pulse transceiver 300 , an oscilloscope 400 , an ultrasonic probe switching control component 500 , a detection box 600 and an ultrasonic probe 700 .

[0067] Among them, the terminal device 100 can be a display device with a display function. The display device may include: a smart TV, a mobile phone, a tablet computer, etc. The terminal device 100 is used to send a movement signal for controlling the movement of the ultrasonic probe 700 to the movement control component 200 after detecting the connected ultrasonic probe 700; notify the ultrasonic pulse transceiver 300 to send a pulse signal; obtain the reflection signal corresponding to each pulse signal received by the ultrasonic pulse transceiver 300, determine the test parameters of the corresponding primitive channel according to the received reflection signal, and determine the detection result of the ultrasonic probe 700 according to the test parameters of each primitive channel.

[0068] The mobile control component 200 is used to move the ultrasonic probe 700 to a detection position corresponding to the probe type of the ultrasonic probe according to the movement signal sent by the terminal device 100. The detection position is determined by the terminal device 100. The terminal device 100 can realize the automatic control operation of the mobile control component 200 through the network port and the standard modbus tcp protocol, and the high-performance servo motor also ensures the accuracy of the X, Y, and Z axis positions of the probe movement.

[0069] In some embodiments, the mobile control assembly 200 further includes a fixture 201, such as Figure 2 The tester can fix the ultrasonic probe 700 on the fixture 201 so that the ultrasonic probe 700 moves along with the movement control component 200 to move the ultrasonic probe 700 to the corresponding detection position.

[0070] The ultrasonic pulse transceiver 300 is a universal ultrasonic pulse generator / receiver. As an example, the terminal device 100 can remotely control the ultrasonic pulse transceiver 300 through serial communication to generate a high-voltage electrical excitation pulse. The excitation pulse signal is converted into an ultrasonic pulse through the ultrasonic transducer of the ultrasonic probe, and then transmitted to the test material or medium. When the ultrasonic signal hits the reflection target, it will be reflected back to the probe. The probe converts the received ultrasonic echo signal into an electrical signal and feeds it back to the ultrasonic pulse transceiver 300.

[0071] In some embodiments, the signal received by the ultrasonic pulse transceiver 300 is processed by adjustable high-pass and low-pass filter signals, and the amplified and filtered signal is output to the oscilloscope 400 for display.

[0072] The oscilloscope 400 is used to display the feedback excitation signal received by the ultrasonic probe 700. The terminal device 100 can control the oscilloscope instrument through the USB port and read the waveform raw data and test parameters of the transmission signal corresponding to each primitive channel from the instrument. As an example, the display interface of the oscilloscope 400 is as follows: Figure 3 After the oscilloscope 400 performs signal analysis on the received reflected signal, the waveform, peak-to-peak value, maximum level, minimum level, amplitude and echo time of the reflected signal can be obtained. Among them, the measurement parameters may include the waveform, peak-to-peak value and echo time of the reflected signal.

[0073] The ultrasonic probe switching control component 500 is connected to the terminal device 100 and is used to drive various types of probes of different models and channels from different manufacturers. In some embodiments, the terminal device 100 can test the ultrasonic probe 700 by running the HUST_NET test program. In some scenarios, the HUST_NET host computer test tool (i.e., the HUST_NET probe test program) communicates and interacts with the single-chip microcomputer in the ultrasonic probe switching control component 500 through the serial port, controls the relay switch in the ultrasonic probe switching control component 500, can accurately control a certain array element channel switch of the ultrasonic probe 700, and can make the signal fidelity between each channel consistent. As an example, the ultrasonic probe switching control component 500 can be a relay conversion box, which can be designed to be compatible with both 260 and 409 probes. By simply replacing the conversion board, fast switching tests of different probe interfaces can be achieved to improve the compatibility of the equipment and save testing costs.

[0074] The detection box 600 includes a reflective target 601 and a medium, and the reflective target 601 is fixedly placed in the medium in the detection box 600. As an example, water can be used as the medium, and the reflective target 601 is fixed at a fixed position on the bottom of the detection box 600 where water is placed, such as Figure 4In some scenarios, when the ultrasonic probe 700 is a planar probe, the reflective surface of the reflective target 601 is a planar surface, such as Figure 5 In another embodiment, when the ultrasonic probe 700 is a curved probe, the emitting surface of the reflective target 601 is a curved surface, such as Figure 6 The curvature of the reflective surface of the reflective target 601 is related to the probe curvature of the ultrasonic probe 700 , so that the ultrasonic signals emitted by each elementary channel of the ultrasonic probe 700 can reach the upper surface of the reflective target 601 at the same time.

[0075] The ultrasonic probe 700 is used to transmit ultrasonic signals. In some embodiments, the ultrasonic probe 700 includes a probe transducer 701, such as Figure 7 As shown. The pulse signal transmitted by the ultrasonic pulse transceiver 300 can be converted into an ultrasonic signal through the probe transducer 701 and transmitted through the elementary channel of the ultrasonic probe 700. In some scenarios, after the ultrasonic signal is transmitted through the reflective target 601, the transmitted ultrasonic signal is converted into an electrical signal through the elementary channel by the probe transducer 701 and transmitted to the ultrasonic pulse transceiver 300.

[0076] In some embodiments, the connection relationship between the components in the detection system of the ultrasonic probe is as follows: Figure 8 The oscilloscope 400 is connected to the ultrasonic pulse transceiver 300 via a coaxial cable, and the ultrasonic pulse transceiver 300 is also connected to the ultrasonic probe adapter control component 500 via a coaxial cable.

[0077] See also Fig. 9 As shown, the present application embodiment provides a detection method of an ultrasonic probe, which can be Figure 1 The terminal device 100 in the embodiment is executed, and the specific process is as follows:

[0078] 901, the terminal device determines the probe type of the connected target probe to be detected; controls the movement control component connected to the terminal device to move the target probe to a detection position corresponding to the probe type.

[0079] In some embodiments, after the target probe to be detected is connected to the detection system of the ultrasound probe, the terminal device may determine the probe type of the connected target probe.

[0080] Furthermore, the terminal device can control the mobile control component to move the corresponding detection position according to the probe type of the target probe. Specifically, the terminal device determines the detection position corresponding to the probe type of the target probe according to the pre-generated correspondence between the probe type and the detection position; the terminal device controls the mobile control component to move the target probe to the detection position corresponding to the probe type of the target probe.

[0081] Exemplarily, the terminal device stores a pre-generated correspondence between the probe type and the detection position. As an example, the correspondence between the probe type and the detection position can be stored in a table, such as Fig.10 As shown. After the target probe is connected to the detection system of the ultrasonic probe, when the terminal device determines that the probe type of the target probe is the first probe type, the coordinates of the detection position corresponding to the first probe type can be determined to be [330, 450, 236]. Further, the mobile control component can be controlled to move to [330, 450, 236], at which time the target probe reaches the detection position.

[0082] 902 , the terminal device controls an ultrasonic pulse transceiver connected to the terminal device to transmit a pulse signal for each elementary channel of the target probe.

[0083] 903. For any pulse signal, the terminal device obtains a reflected signal corresponding to the pulse signal received by the ultrasonic pulse transceiver.

[0084] The reflected signal is obtained by collecting the ultrasonic signal, and the ultrasonic signal is an ultrasonic signal emitted by the target probe under the drive of the pulse signal.

[0085] In some scenarios, the ultrasonic pulse transceiver may specifically include an ultrasonic pulse generator and an ultrasonic pulse receiver. After the terminal device initializes the ultrasonic pulse generator to send a pulse signal, it controls the relays in the ultrasonic probe switching control component one by one to open the corresponding primitive channel of the target probe.

[0086] In some embodiments, the pulse signal emitted by the ultrasonic pulse generator is converted into an ultrasonic signal by a probe transducer in a cable and a target probe and is emitted through a primitive channel.

[0087] In some embodiments, after the ultrasonic signal is reflected by the reflective target, the reflected ultrasonic signal is received through the elementary channel. The reflected ultrasonic signal passes through the probe transducer in the target probe to convert the transmitted ultrasonic signal into an electrical signal, which is then sent to the pulse receiver to obtain the transmission signal of each pulse signal.

[0088] As an example, taking the third elementary channel of the target probe as an example, the third elementary channel is recorded as CH3, then the signal transmission and reception process is as follows Fig.11As shown. The ultrasonic pulse generator generates a pulse signal, which is turned on by the relay in the ultrasonic probe transfer control component. The pulse signal is converted into an ultrasonic signal by the probe transducer in the target probe, and the ultrasonic signal is transmitted through CH3. After the ultrasonic signal is reflected by the reflection target, CH3 receives the reflected ultrasonic signal, converts the ultrasonic signal into an electrical signal through the probe transducer, obtains the reflected signal of the pulse signal, and sends the reflected signal to the ultrasonic pulse receiver.

[0089] 904. Determine a test parameter of a corresponding primitive channel according to the reflected signal.

[0090] In some embodiments, the test parameters include echo time and peak-to-peak value. The terminal device determines the test parameters of the corresponding elementary channel according to the reflected signal, which can be implemented in the following manner: the terminal device controls the pulse transceiver to input the reflected signal into an oscilloscope connected to the pulse transceiver through a cable; the terminal device obtains the echo time and peak-to-peak value of the reflected signal obtained after the oscilloscope performs signal analysis on the reflected signal.

[0091] Exemplarily, the reflection signal may also be referred to as an excitation signal. The excitation signal is transmitted to an oscilloscope and displayed on the oscilloscope.

[0092] In some scenarios, the terminal device can control the oscilloscope instrument through the USB interface and read the corresponding waveform data and test parameters from the instrument. Figure 3 As shown, the display interface of the oscilloscope displays the waveform of the excitation signal, as well as the peak-to-peak value, maximum level, minimum level, amplitude and echo time of the excitation signal.

[0093] As an example, taking a 192-channel target probe as an example, after the oscilloscope processes the transmitted signal of each primitive channel, the peak-to-peak value is recorded, such as Fig.12 shown.

[0094] In some scenarios, the reflected signal data output by the oscilloscope can be imported into the MATLAB drawing software. Through algorithm processing, the disordered single-point data can be drawn into an intuitive test graph, which improves the efficiency and recognition of data analysis and facilitates intuitive judgment of the performance of the probe.

[0095] In some embodiments, the test parameters include frequency and bandwidth. The terminal device determines the test parameters of the corresponding primitive channel according to the reflected signal, which can be specifically implemented in the following manner: the terminal device performs frequency domain transformation on the reflected signal to obtain frequency domain waveform data; the terminal device determines the frequency and bandwidth of the reflected signal of the primitive channel according to the frequency domain waveform data.

[0096] In some scenarios, the frequency of the reflected signal includes an initial center frequency and a target center frequency after attenuation processing. The terminal device determines the frequency and bandwidth of the reflected signal of the primitive channel according to the frequency domain waveform data, including: the terminal device determines the initial center frequency of the reflected signal according to the frequency domain waveform data; and the terminal device attenuates the frequency domain waveform data according to the set attenuation processing method, and determines the target center frequency and bandwidth corresponding to the frequency domain waveform data after attenuation processing.

[0097] Exemplarily, for each elementary channel, the target center frequency and bandwidth of the transmit signal after -6 dB processing and -6 dB processing, as well as the target center frequency and bandwidth after -20 dB processing of the transmit signal are determined.

[0098] As an example, the frequency domain waveform of the reflected signal of the target probe after frequency domain processing is as follows: Fig.13 As shown. The highest point of each waveform is the initial center frequency. The intersection of the dotted line and the waveform is the frequency intersection after -6dB, and the intersection of the solid line and the waveform is the frequency intersection after -20DB. As an example, the frequency intersections of -6dB are 5.19MHz and 11.24MHZ, respectively. The target center frequency after -6dB processing is (11.24+5.19) / 2=8.21MHz, and the bandwidth after -6dB processing is (11.24-5.19) / 8.21=73.7%.

[0099] 905, the terminal device determines the detection result of the target probe according to the test parameters of each primitive channel.

[0100] In some embodiments, the test parameters of each primitive channel can be compared with the corresponding threshold range. If the test parameters of a primitive channel are not within the corresponding threshold range, the detection result of the target probe is determined to be a failure; if the test parameters of each primitive channel are within the corresponding threshold range, the detection result of the target probe is a passing test.

[0101] As an example, the test parameters of each primitive channel can be displayed in a graph, such as Fig.14 The test parameters of each elementary channel include echo time, peak-to-peak value, initial center frequency, -6dB center frequency, -6dB bandwidth, -20dB center frequency and -20dB bandwidth.

[0102] Exemplarily, the echo time, peak-to-peak value, initial center frequency, -6dB center frequency, -6dB bandwidth, -20dB center frequency and -20dB bandwidth respectively correspond to threshold ranges. When the test parameters of each primitive channel are within the corresponding threshold range, the detection result of the target probe is determined to be passed. If the test parameters of at least one primitive channel are not within the corresponding threshold range, the detection result of the target probe is determined to be failed.

[0103] Based on the above scheme, after determining that the target probe to be detected is connected, the terminal device moves to the detection position according to the type of the target probe, and transmits a signal based on the detection position and receives a reflected signal, and determines the test parameters and the test results based on the reflected signal. In this application, the tester can operate simply and only needs to fix the target probe on the mobile control component. The terminal device automatically moves the target probe to the detection position through the mobile control component. The difficulty of adjusting the probe test position is greatly reduced, the labor cost is reduced, the automatic detection of ultrasonic probes is realized, and the test efficiency is improved.

[0104] In some embodiments, a test report document may be automatically generated based on the test parameters to facilitate review by test personnel.

[0105] In some embodiments, the terminal device may generate the corresponding relationship between the probe type and the detection position in the following manner. The specific process is as follows: Fig.15 As shown:

[0106] 1501. After detecting the connected test probe, the terminal device determines the probe type of the test probe.

[0107] 1502, the terminal device controls the movement control component to move the test probe to an initial detection position, and controls the ultrasonic pulse transceiver to transmit a pulse signal for each elementary channel of the test probe.

[0108] 1503. The terminal device determines the time delay corresponding to the reflected signal received by each primitive channel of the test probe.

[0109] 1504. When the time delay of the reflection signal corresponding to each primitive channel is different, the mobile control component is controlled to adjust the detection position of the test probe and the ultrasonic pulse transceiver is controlled again to transmit a pulse signal outward until it is determined that the time delay of the reflection signal corresponding to each primitive channel received is the same, and the current detection position is bound to the probe type of the test probe.

[0110] Based on the above method, the detection position of each probe type can be predetermined by the detection system of the ultrasonic probe, and the corresponding relationship between the detection position and each probe type can be saved.

[0111] Based on the same technical concept, see Fig.16 As shown, an embodiment of the present application provides an electronic device 1600, which can perform any step in the above-mentioned ultrasonic probe detection method. To avoid repetition, it is not repeated here. The device 1600 includes a memory 1601 and a processor 1602.

[0112] The memory 1601 is used to store program instructions;

[0113] The processor 1602 is used to call the program instructions stored in the memory and execute each step of the above-mentioned ultrasonic probe detection method according to the obtained program.

[0114] In the embodiment of the present application, the processor 1602 may be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component, and may implement or execute the methods, steps, and logic block diagrams disclosed in the embodiment of the present application.
