[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] Figure 1 This is a flow chart of a transducer testing method provided by an embodiment of the present invention. This embodiment is used to determine whether the transducer under the target ultrasonic front end meets the predetermined test conditions. The method can be executed by a transducer testing device. The transducer testing device can be implemented in the form of hardware and / or software. The transducer testing device can be configured in a processor of an electronic device. Figure 1 As shown, the method includes:

[0030] S110 . Based on a pulse transmitter and receiver, obtain a first transmitting signal for driving the transducer under test and a first receiving signal associated with the first transmitting signal received by the transducer under test.

[0031] This embodiment can transmit a first transmission signal to the transducer under test based on the pulse transmitter and receiver to drive the transducer under test to generate ultrasonic waves; when the transducer under test outputs the ultrasonic waves generated based on the first transmission signal to the set detection object, the ultrasonic waves will generate an echo signal when encountering the set detection object, and the transducer under test receives the echo signal, which is the first reception signal. The pulse transmitter and receiver can obtain the first reception signal, and both the first transmission signal and the first reception signal can be exported to the set electronic device, or exported to the set electronic device through an oscilloscope.

[0032] S120. Input the first transmission signal and the first reception signal into a pre-trained data analysis model to obtain a predicted reception signal, wherein the pre-trained data analysis model is used to predict, based on the first transmission signal and the first reception signal, an echo signal received by the transducer to be tested detected by the target ultrasonic front end when the target ultrasonic front end transmits a second transmission signal to the transducer to be tested.

[0033] The target ultrasound front end includes a transmitting unit and a receiving unit, wherein the transmitting unit is used to transmit a second transmitting signal to the transducer under test, and the receiving unit is used to obtain an echo signal received by the transducer under test, which is also called a second receiving signal. The second transmitting signal can be configured to be the same as or different from the first transmitting signal.

[0034] This step is intended to predict the echo signal (second received signal) received by the transducer under test detected by the target ultrasonic front end based on the input data (first transmitted signal) and output data (first received signal) of the transducer under test, so that in actual transducer testing, there is no need to combine each transducer under test with a reference ultrasonic front end to obtain a target ultrasonic front end, and then test the performance of the transducer under test under the target ultrasonic front end, which can significantly improve the test speed of the transducer under test. It should be noted that the reference ultrasonic front end in this embodiment does not include a transducer.

[0035] Among them, the pre-trained data analysis model is trained by the data analysis model based on the target loss function, and the target loss function includes at least one signal index difference item, and the signal index difference item includes the difference between the predetermined index data of the echo signal actually detected by the target ultrasonic front end and the corresponding predetermined index data of the predicted received signal.

[0036] In one embodiment, the at least one signal indicator difference term includes at least one of a maximum sound pressure position difference term, a spectrum difference term and a phase difference term. The target loss function determined in this embodiment can improve the prediction accuracy of the pre-trained data analysis model.

[0037] Based on the above-mentioned embodiment, the target loss function includes a received signal difference term, a maximum sound pressure position difference term and a spectrum difference term; the received signal difference term is configured as the absolute value of the difference between the actual received signal of the target ultrasonic front end and the predicted received signal; the maximum sound pressure position difference term is configured as the difference between the maximum sound pressure position of the predicted received signal and the maximum sound pressure position of the actual received signal; the spectrum difference term is configured as the difference between the spectrum of the predicted received signal and the spectrum of the actual received signal.

[0038] Specifically, the objective loss function can be expressed as:

[0039]

[0040] Among them, α|xx ′ | is the received signal difference term, x is the actual echo signal received by the transducer under test detected by the target ultrasonic front end, and the actual echo signal is recorded in the label of the training sample; x ′ receiving signals for predictions of data analysis models; is the maximum sound pressure position difference term, t p For x ′ is the difference between the time when the maximum instantaneous value appears and the time when the receiving unit of the target ultrasound front end detects x, and fs is the sampling rate of the target ultrasound front end; γ(fft(x ′ )-fft(H(t)*f)) is the frequency spectrum difference term, H(t) represents the equivalent response of the transducer to be tested for transmitting and receiving, and f is the frequency of the second transmitting signal.

[0041] It should be noted that the training of the data analysis model is completed based on the first sample set to obtain a pre-trained data analysis model. The first sample set includes training samples for different transducers, and the training samples include a first transmission signal and a first reception signal of the corresponding transducer obtained based on a pulse transmitter and receiver, and a second transmission signal sent by the target ultrasonic front end of the corresponding transducer to the corresponding transducer and an echo signal received by the corresponding transducer, and the echo signal is used as a label. The first transmission signal and the second transmission signal can be set according to industry test requirements.

[0042] In one embodiment, after the predicted received signal is determined, the set indicator data of the predicted received signal is displayed in a visualization interface so that the user can intuitively understand the signal quality of the predicted received signal.

[0043] S130: Determine whether the transducer to be tested in the target ultrasound front end meets a predetermined test condition based on the predicted received signal.

[0044] In one embodiment, the predicted received signal is input into a pre-trained classification model to obtain a classification identifier of whether the transducer to be tested meets a predetermined test condition.

[0045] Exemplarily, if the pre-trained classification model outputs a first classification identifier, it indicates that the transducer to be tested has passed the predetermined test conditions, that is, the transducer to be tested has passed the test and is a qualified transducer; if the pre-trained classification model outputs a second classification identifier, it indicates that the transducer to be tested has not passed the predetermined test conditions, that is, the transducer to be tested has not passed the test and is an unqualified transducer.

[0046] The classification model is trained based on the second sample set to obtain a pre-trained classification model, wherein each training sample in the second sample set includes a label and an echo signal (second received signal) received by each transducer detected by the target ultrasound front end, and the label includes an identifier for indicating whether the second received signal meets a predetermined test condition.

[0047] In one embodiment, after the predicted received signal is determined, the target indicator data of the predicted received signal is determined based on the existing ultrasonic signal analysis method, and whether the transducer to be tested meets the predetermined test conditions is determined based on the target indicator data, and a first classification identifier is generated to indicate that the predetermined test conditions are met, or a second classification identifier is generated to indicate that the predetermined test conditions are not met.

[0048] The technical solution of the transducer testing method provided in the embodiment of the present invention obtains a first transmitting signal for driving the transducer to be tested and a first receiving signal received by the transducer to be tested based on the first transmitting signal in a separate test of the transducer to be tested; then uses a pre-trained data analysis model to analyze the first transmitting signal and the first receiving signal, predicts the echo signal received by the transducer to be tested detected by the target ultrasonic front end when the target ultrasonic front end transmits a second transmitting signal to the transducer to be tested, and outputs the echo signal as the predicted receiving signal; finally, based on the predicted receiving signal, determines whether the transducer to be tested under the target front end meets the predetermined test conditions. Since the target ultrasonic front end is the core structure of the ultrasonic device, the performance of the transducer to be tested in the ultrasonic device including the target ultrasonic front end can be determined based on the test result, thereby achieving the goal of improving the comprehensiveness of the transducer test content without increasing the complexity of the test process.

[0049] Figure 2 This is a flow chart of a transducer testing method provided by an embodiment of the present invention. This embodiment adds a step of determining a predetermined resolution of an ultrasound image determined by a target ultrasound front end of the transducer to be tested based on the previous embodiment. Figure 2 As shown, the method includes:

[0050] S210 . Based on a pulse transmitter and receiver, obtain a first transmitting signal for driving the transducer under test and a first receiving signal associated with the first transmitting signal received by the transducer under test.

[0051] S220. Input the first transmission signal and the first reception signal into a pre-trained data analysis model to obtain a predicted reception signal, wherein the pre-trained data analysis model is used to predict, based on the first transmission signal and the first reception signal, an echo signal received by the transducer to be tested detected by the target ultrasonic front end when the target ultrasonic front end transmits a second transmission signal to the transducer to be tested.

[0052] S230: Determine whether the transducer to be tested in the target ultrasound front end meets a predetermined test condition based on the predicted received signal.

[0053] S240: Determine, according to the predicted received signal, an axial resolution and / or a lateral resolution of an ultrasound image determined by a target ultrasound front end including the transducer to be tested.

[0054] Axial resolution refers to the minimum distance between two adjacent structures that can be distinguished in the direction of the ultrasonic beam. It depends on the pulse width of the ultrasonic beam and the center frequency of the ultrasonic wave. The shorter the pulse width, the higher the axial resolution. Reducing the number of cycles of the transmitted pulse or reducing the ultrasonic wavelength can improve the axial resolution; high-frequency ultrasonic waves have a short wavelength, so the axial resolution can be improved. High-frequency transducers can produce short pulse lengths, thereby improving the axial resolution.

[0055] Lateral resolution refers to the minimum distance between two adjacent structures that can be resolved in a plane perpendicular to the direction of the ultrasound beam. It depends primarily on the width of the ultrasound beam. The narrower the ultrasound beam width, the higher the lateral resolution. Lateral resolution deteriorates with increasing depth because the beam converges to its narrowest width and then widens with increasing distance.

[0056] In one embodiment, the predicted received signal is input into a pre-trained resolution prediction model to obtain the axial resolution and / or lateral resolution of the ultrasound image determined by the target ultrasound front end including the transducer to be tested. This embodiment can quickly determine the axial resolution and / or lateral resolution of the ultrasound image determined by the target ultrasound front end including the transducer to be tested based on the predicted received signal.

[0057] The training of the resolution prediction model is completed based on the third sample set to obtain a pre-trained resolution prediction model. For the case where only the axial resolution can be predicted, the training samples in the third sample set include the second received signal received by the target ultrasound front end and the label, and the label includes the axial resolution corresponding to the second received signal; for the case where only the lateral resolution can be predicted, the training samples in the third training sample set include the second received signal received by the target ultrasound front end and the label, and the label includes the lateral resolution corresponding to the second received signal; for the case where the axial resolution and the lateral resolution can be predicted at the same time, the label includes the axial resolution and the lateral resolution corresponding to the second received signal.

[0058] In one embodiment, when an instruction for determining an axial resolution is detected, the center frequency of the predicted received signal and the width of the acoustic beam formed by the predicted received signal are determined; then, based on the center frequency and the width, the axial resolution of the ultrasonic image determined by the target ultrasonic front end including the transducer to be tested is determined; when an instruction for determining a lateral resolution is detected, the width of the acoustic beam formed by the predicted received signal is predicted; then, based on the width, the lateral resolution of the ultrasonic image determined by the target ultrasonic front end including the transducer to be tested is determined.

[0059] After the axial resolution and / or lateral resolution are determined, determine whether the axial resolution and / or lateral resolution meet the corresponding resolution conditions, and based on whether the axial resolution and / or lateral resolution meet the corresponding resolution conditions, determine whether the target ultrasonic front end including the transducer to be tested meets the resolution test conditions.

[0060] If the target ultrasonic front end including the transducer to be tested meets the resolution test conditions, it means that it has passed the resolution test, and therefore a first prompt information indicating that the target ultrasonic front end has passed the resolution test is displayed in the visualization interface; if the target ultrasonic front end including the transducer to be tested does not meet the resolution test conditions, it means that it has not passed the resolution test, and therefore a second prompt information indicating that the target ultrasonic front end has not passed the resolution test is displayed in the visualization interface.

[0061] The technical solution provided by the embodiment of the present invention realizes the determination of the axial resolution and / or lateral resolution of the ultrasound image determined by the target ultrasound front end including the transducer to be tested based on the predicted received signal, thereby determining whether the target ultrasound front end including the transducer to be tested is qualified, whether the target ultrasound front end can be used to assemble ultrasound equipment, etc., further improving the comprehensiveness of the transducer detection content.
