[0036] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0037] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0038] In experiments that use ultrasound to stimulate organisms or cells, one experiment often uses multiple ultrasonic signals with different parameters, and the same ultrasonic signal may be repeated multiple times to stimulate the organism or cell. During the experimental test, the set ultrasonic signals are usually executed sequentially. Since organisms are adaptable, the previous parameters executed sequentially will affect the subsequent parameters, which is not conducive to improving the reliability of the test results.

[0039] Based on this, the present application embodiment proposes an ultrasonic excitation system, such as Figure 1 As shown, the system includes a control terminal 101, a signal generator 102, a high-frequency electric-controlled switch 103 and a power amplifier 104, wherein:

[0040] The control terminal 101 is used to obtain ultrasonic parameters and random parameters, and convert the ultrasonic parameters and the random parameters into operation instructions and send them to the signal generator 102. The random parameters are used to randomly select ultrasonic signals for output.

[0041] The signal generator 102 is used to generate an ultrasonic signal and a level control signal according to the operation instruction, and send the ultrasonic signal to the signal input pin of the high-frequency electronically controlled switch 103 through a first output channel, and send the level control signal to the control pin of the high-frequency electronically controlled switch 103 through a second output channel.

[0042] The high-frequency electric-controlled switch 103 selects the ultrasonic signal according to the level control signal, and outputs the selected ultrasonic signal through a signal output pin of the high-frequency electric-controlled switch 103 .

[0043] The power amplifier 104 is used to amplify the ultrasonic signal to output ultrasonic waves through the amplified ultrasonic signal.

[0044] Among them, the control terminal 101 may include devices such as desktop computers, laptops, tablet computers, and smart terminals. A setting interface may be generated at the control terminal 101, and the setting parameters input by the user may be received through the generated setting interface. The ultrasonic parameters and random parameters input by the user may be received through the setting interface of the control terminal 101. Among them, the ultrasonic parameters are used to determine different ultrasonic waves, and the random parameters are used to randomly select the ultrasonic signals to be output. For example, the setting information of the ultrasonic parameters may be received through the setting interface generated by the control terminal 101, which may include one or more of the center frequency of the ultrasonic wave, the waveform of the ultrasonic wave, the amplitude of the ultrasonic wave, the duty cycle of the ultrasonic wave, the repetition frequency of the ultrasonic signal, and the duration of the ultrasonic wave. Alternatively, the setting information of the random parameters may be received through the setting interface, which may include one or more of the random execution parameters of different ultrasonic signals and the random interval duration parameters of different ultrasonic signals.

[0045] The center frequency of the ultrasonic wave is the frequency in the middle of the frequency band of the ultrasonic wave. The frequency range of the ultrasonic wave used for the test can be determined according to the test requirements, and a plurality of different center frequencies can be set within the frequency range. In a possible implementation, parameters such as the upper sideband or the lower sideband of the frequency band of the ultrasonic wave may also be included.

[0046] The waveform of the ultrasonic wave may include a sine wave, a square wave, a triangular wave, etc. When the set waveform of the ultrasonic wave is a triangular wave or a square wave, the ultrasonic parameter may also include parameters such as the duty cycle of the ultrasonic wave. By setting different duty cycles, ultrasonic waves of different intensities may be obtained.

[0047] The duration of an ultrasonic wave can be used to indicate the duration of a single ultrasonic wave signal. Based on the duration of an ultrasonic wave and the duty cycle of the ultrasonic wave, the idle time and effective occupied time of the ultrasonic wave in a single cycle can be determined. Based on the number of repetitions of the ultrasonic wave, the duration of the ultrasonic wave in a single cycle can be determined. For example, if the duration of an ultrasonic wave is T1 and the number of repetitions of the ultrasonic wave is N, then the duration of the ultrasonic wave in a single cycle is T = T1*N.

[0048] In possible implementations, the ultrasound parameters and random parameters may not be limited to being obtained through the setting interface, but may also be obtained through other methods, such as receiving the ultrasound parameters and random parameters through a communication interface, or pre-storing the ultrasound parameters and random parameters through a storage medium.

[0049] In a possible implementation, when the control terminal 101 obtains the ultrasound parameters and random parameters through the setting interface, the ultrasound graph corresponding to the set ultrasound parameters can be displayed in a predetermined area in the setting interface. Based on the ultrasound graph displayed in the setting interface, the user can obtain the required ultrasound waveform more vividly.

[0050] The random parameters in the embodiments of the present application can be used to randomly select the set ultrasonic signal and randomly determine the interval duration between two ultrasonic signals. For example, multiple different ultrasonic signals can be obtained according to the arrangement and combination of various ultrasonic parameters. Including determining multiple different ultrasonic signals according to different ultrasonic center frequencies, different ultrasonic waveforms, different ultrasonic amplitudes, different ultrasonic duty cycles, ultrasonic signal repetition frequencies and different ultrasonic durations. The set ultrasonic signal can be randomly selected by random parameters, and the interval duration between two ultrasonic signals can be determined by random parameters.

[0051] In possible implementations, in order to further improve the reliability of the system, in addition to simple randomization, one or more of block randomization, segmented randomization, stratified block randomization, and dynamic randomization can also be used. For example, block randomization or block stratified randomization can be used to make the number of occurrences of ultrasonic parameters in different intervals within a set range the same, thereby reducing the impact of uneven occurrences of ultrasonic parameters in different intervals on the test results, thereby helping to improve the reliability of the test results of the ultrasonic experiment.

[0052] In the embodiment of the present application, the control terminal 101 can convert the acquired ultrasonic parameters into operation instructions that can be recognized by the signal generator 102, and send the operation instructions to the signal generator through a serial communication protocol or other communication protocols. For example, when the signal generator 102 is an oscilloscope, the acquired ultrasonic parameters and random parameters can be converted into NI-VISA (an oscilloscope interface protocol) operation instructions that can be recognized by the oscilloscope, so that the oscilloscope can generate an ultrasonic signal corresponding to the acquired hyperparameters according to the converted NI-VISA operation instructions.

[0053] In a possible implementation, the signal generator 102 is not limited to an oscilloscope, and an FPGA or other controller may be used as the signal generator 102 to recognize operation instructions and generate corresponding ultrasonic signals or corresponding level control signals according to the recognized operation instructions.

[0054] The level control signal in the embodiment of the present application may include a level signal such as TTL. The level control signal may include a first level and a second level, which are respectively used to represent different control states. It includes selecting an ultrasonic signal input into the high-frequency electric-controlled switch through a first level, and filtering out the ultrasonic signal input into the high-frequency electric-controlled switch through a second level. For example, for a level signal of TTL (transistor transistor logic, transistor-transistor logic level), it may include a low-level signal and a high-level signal. The ultrasonic signal input into the high-frequency electric-controlled switch 103 may be selected through a low level, and the ultrasonic signal input into the high-frequency electric-controlled switch may be filtered out through a high level.

[0055] By inputting the level control signal into the high-frequency electric control switch, the number of repetitions of the ultrasonic signal and the interval length of different ultrasonic signals can be controlled according to the level control signal. Figure 2As shown, the level control signal of TTL includes a high level and a low level. The duration of the first ultrasonic signal and the second ultrasonic signal is determined according to the number of repetitions and the duration of a single ultrasonic wave. When the duration of the ultrasonic signal ends, the level signal of the level control signal is changed so that the high-frequency electric-controlled switch outputs an idle signal, that is, stops outputting the ultrasonic signal. Alternatively, according to the interval duration between the two ultrasonic signals, when the interval duration ends, the level signal of the level control signal is changed so that the high-frequency electric-controlled switch outputs the second ultrasonic signal.

[0056] In a possible implementation, after the signal generator 102 completes the output of a certain ultrasonic signal, it can return a signal to complete the input to the control terminal 101, so that the control terminal 101 sends corresponding operation instructions to the signal generator according to the subsequent ultrasonic signal and the interval duration, thereby realizing the use of ultrasonic signals with multiple different parameters in one implementation.

[0057] exist Figure 1 Based on the ultrasonic excitation system shown in FIG. , the present application embodiment provides an ultrasonic excitation method, such as Figure 3 As shown, the method includes:

[0058] In S301, the control terminal acquires ultrasonic parameters and random parameters, and converts the ultrasonic parameters and random parameters into operation instructions and sends them to the signal generator.

[0059] The random parameters are used to randomly select an ultrasonic signal for output.

[0060] The ultrasonic parameters and random parameters in the embodiment of the present application can be converted into operation instructions by the control terminal, and the operation instructions can be sent to the signal generator through a serial communication interface or other communication interfaces.

[0061] The ultrasonic parameters in the embodiments of the present application may be one or more of the center frequency of the ultrasonic wave, the waveform of the ultrasonic wave, the amplitude of the ultrasonic wave, the duty cycle of the ultrasonic wave, the repetition frequency of the ultrasonic wave, and the duration of the ultrasonic wave. The random parameters include one or more of the random execution parameters of different ultrasonic signals and the random interval duration parameters of different ultrasonic signals.

[0062] In order to facilitate the signal generator to effectively identify the ultrasonic parameters and random parameters, the ultrasonic parameters and random parameters can be converted into operation instructions that the signal generator can identify. When the signal generator is an oscilloscope, the operation instructions may include NI-VISA operation instructions.

[0063] In S302, the signal generator generates an ultrasonic signal and a level control signal according to the operation instruction, and sends the ultrasonic signal and the level control signal to the high-frequency electronically controlled switch.

[0064] In order to facilitate the control of the ultrasonic signal generated by the signal generator, the ultrasonic signal can be determined according to one or more of the center frequency of the ultrasonic wave in the ultrasonic signal, the waveform of the ultrasonic wave, the amplitude of the ultrasonic wave, the duty cycle of the ultrasonic wave, the repetition frequency of the ultrasonic signal and the duration of the ultrasonic wave. In the embodiment of the present application, a high-precision DDS (full name in Chinese is Direct Digital Synthesizer, full name in English is Direct Digital Synthesizer) can be used to generate a carrier signal of the required frequency, and then a digital signal of a predetermined size, such as an 8*1024 digital signal, is stored in a digital memory, and the digital signal is converted into an analog signal by a digital-to-analog converter. The carrier signal and the analog signal can be mixed by a multiplier to form an ultrasonic signal with a specific duty cycle. For example, an ultrasonic operation instruction can be generated according to one or more of the center frequency of the ultrasonic wave, the waveform of the ultrasonic wave, the amplitude of the ultrasonic wave, the duty cycle of the ultrasonic wave, the repetition frequency of the ultrasonic signal and the duration of the ultrasonic wave, and an ultrasonic signal is generated according to the ultrasonic operation instruction.

[0065] The level control signal may be generated according to one or more of the center frequency of the ultrasound wave, the waveform of the ultrasound wave, the amplitude of the ultrasound wave, the duty cycle of the ultrasound wave, the repetition frequency of the ultrasound signal, and the duration of the ultrasound wave. For example, the level operation instruction may be generated according to one or more of the duration of the ultrasound wave, the random number of repetitions of the ultrasound signal, the random execution parameters of different ultrasound signals, and the random interval duration of different ultrasound signals, and the level control signal may be generated according to the level operation instruction.

[0066] After the signal generator completes the generation of a certain ultrasonic signal, it can feedback the completion status to the control terminal. The control terminal outputs the operation instruction corresponding to the subsequent ultrasonic signal to the signal generator according to the feedback information of the signal generator.

[0067] In S303, the high-frequency electric-controlled switch selects the ultrasonic signal according to the level control signal.

[0068] The corresponding ultrasonic signal can be generated in the signal generator according to the ultrasonic operation instruction converted by the determined ultrasonic parameter. In order to facilitate the control of the duration of the ultrasonic signal and the interval length of different ultrasonic signals, the following can be done: Figure 2 As shown, through the level operation instruction, it is input to the high-frequency electric control switch to select and screen the generated ultrasonic signal to obtain the ultrasonic signal of the required duration, and control the interval duration of different ultrasonic signals.

[0069] In S304, the ultrasonic signal selected by the high-frequency electric-controlled switch is received and amplified by the signal amplifier.

[0070] According to the ultrasonic signal output by the high-frequency electric-controlled switch, the ultrasonic signal can be amplified by a signal amplifier, so that the amplified ultrasonic signal can excite the ultrasonic probe, and the corresponding ultrasonic wave is output through the ultrasonic pressure, which is used for stimulation experiments on organisms or cells.
