Reference to "embodiments" herein means that a particular feature, result, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

First, refer to Figure 1, which is a schematic diagram of an application scenario of a microwave neuromodulation method provided in an embodiment of the present application. Among them, microwave neuromodulation is a non-invasive radiofrequency neuromodulation technology. Compared with traditional electrical, magnetic, optical, ultrasonic and other neuromodulation technologies, microwave neuromodulation will not cause trauma to brain tissue. Microwaves are electromagnetic waves in a specific frequency band that can inhibit the excitability of brain neurons. Therefore, microwave neuromodulation can be used to treat diseases caused by excessive brain excitation, such as epilepsy, mental illness, and so on.

Exemplarily, as shown in FIG1 , when microwave neuromodulation is performed on a subject, the target parameters of microwave neuromodulation are first set on the operating table of the distributed microwave neuromodulation device. The target parameters may include, for example, a preset radiation area, the positions of multiple radiation points in the preset radiation area, the preset radiation intensity of each radiation point, etc. Then, microwave neuromodulation is performed on the subject's brain based on the above target parameters.

It should be noted that the distributed microwave neuromodulation device is connected to an antenna, which is used to transmit microwaves, and the microwave field formed by the transmitted microwaves can radiate the preset radiation area of the brain. Optionally, an infrared detector can be set on the antenna, for example, and the infrared detector can obtain the subject's brain image and send the subject's brain image to the operating console of the distributed microwave neuromodulation device. The operating console displays the image after receiving the subject's brain image. In addition, the distributed microwave neuromodulation device can establish a coordinate system using the microwave emission point of the antenna as the coordinate origin, thereby determining the coordinates of each point in the subject's brain image. Thus, the user can select a preset radiation area on the operating console, and set the coordinates of each radiation point in the preset radiation area and the preset radiation intensity of each radiation point to achieve microwave neuromodulation of the subject's brain.

Optionally, when the distributed microwave neuromodulation device is connected to multiple antennas, a coordinate system can be established using the microwave emission point of the target antenna among the multiple antennas as the coordinate origin to determine the coordinates of each point in the subject's brain image. The number of antennas is not limited herein.

In the embodiment of the present application, the distributed microwave neural control device is a microwave signal generating and processing device, which can realize the generation, amplification, filtering, modulation, and other processing of microwave signals, and generate an input signal for the antenna. Among them, the input signal of the antenna is an alternating current signal of a specific frequency. The input signal oscillates on the antenna to form microwaves, which are emitted into the air through the microwave emission point of the antenna to form a microwave field. By controlling the input signal of the antenna, microwaves with different field source intensities can be emitted, and the microwave field formed by microwaves with different field source intensities can produce radiation of different intensities to the same area. Therefore, the distributed microwave neural control device can determine the field source intensity of the microwaves emitted by the antenna based on the position of each radiation point in the above-mentioned preset radiation area and the preset radiation intensity of each radiation point, thereby transmitting the input signal corresponding to the field source intensity to the antenna, so as to generate radiation with an intensity of the preset radiation intensity corresponding to the radiation point to each radiation point in the subject's brain.

It should be noted that since microwaves need to be transmitted in the subject's cerebral cortex and reach the preset radiation area, attenuation will occur during the microwave transmission process, resulting in the microwave field formed by the microwaves generating weaker radiation at each radiation point in the preset radiation area, making the accuracy of microwave neural regulation lower. In addition, microwaves will also affect other brain tissues in the conduction pathway, causing unnecessary stimulation effects.

To this end, the present application provides a distributed microwave nerve regulation device. Referring to FIG2 , FIG2 is a schematic diagram of the structure of a distributed microwave nerve regulation device provided in the present application.

As shown in FIG2 , the distributed microwave neural control device 200 includes: a control paradigm modulator 201, a signal generator 202, a signal amplifier 203, and a signal modulator 204. Among them, the output end of the signal generator 202 is connected to the input end of the signal amplifier 203, and the control end of the signal generator 202 is connected to the first end of the control paradigm modulator 201. The output end of the signal amplifier 203 is connected to the input end of the signal modulator 204. The control end of the signal modulator 204 is connected to the second end of the control paradigm modulator 201, and the signal modulator 204 includes a plurality of output ends, and the plurality of output ends of the signal modulator 204 are connected one-to-one with the input ends of the plurality of antennas of the antenna array. As shown in FIG2 , the first output end of the signal modulator 204 is connected to the input end of the first antenna 211, the second output end of the signal modulator 204 is connected to the input end of the second antenna 212, and the third output end of the signal modulator 204 is connected to the input end of the third antenna 213.

It can be understood that the embodiments of the present application are only described by taking the antenna array including three antennas as an example, and the present application does not specifically limit the number of antennas in the antenna array.

In the embodiment of the present application, when microwave nerve regulation is performed on a subject, the control paradigm modulator 201 controls the signal generator 202 to generate a microwave signal. Specifically, after the target parameters of microwave nerve regulation are set on the operating table of the distributed microwave nerve regulation device 200, the control paradigm modulator 201 controls the signal generator 202 to generate a microwave signal to perform microwave nerve regulation on the subject.

Exemplarily, the signal generator 202 is a device based on a cross-coupling structure, which provides voltage gain by isolating the load impedance effect through a buffer. By changing the load impedance of the common source amplifier, the buffer can control the output power of the excitation source to generate a microwave signal. The microwave signal is an alternating current signal of a specific frequency. By processing the microwave signal, the microwave signal can be converted into an input signal for each antenna so that each antenna emits a microwave corresponding to the input signal of the antenna. The control paradigm modulator 201 can control the on and off of the signal generator 202 to control the signal generator 202 to generate a microwave signal.

Optionally, the control paradigm modulator 201 can control the on-off frequency of the signal generator 202 so that the signal generator 202 generates a microwave signal of a target frequency. It should be noted that the frequency of the input signal of each antenna obtained after the microwave signal is processed is the same as the frequency of the microwave signal, and the frequency of the input signal of each antenna is the same as the frequency of the microwave emitted by each antenna. To this end, the control paradigm modulator 201 can be used to control the frequency of the microwave signal generated by the signal generator 202 so that each antenna emits microwaves of a target frequency. When the frequency of the microwaves emitted by each antenna is determined, the microwave field formed by the microwaves emitted by each antenna is only determined by the field source strength of the microwaves emitted by each antenna. Therefore, by determining the field source strength of the microwaves emitted by each antenna, microwave neural regulation of a preset radiation area of the subject's brain can be achieved.

It is understandable that the embodiment of the present application is only described by controlling the on and off of the signal generator 202 by regulating the paradigm modulator 201 to generate a microwave signal of a target frequency. Those skilled in the art can also generate a microwave signal of a preset frequency directly through the signal generator 202, which is not limited here.

Then, the signal amplifier 203 amplifies the microwave signal to obtain an amplified signal. The signal amplifier 203 is a low noise amplifier (LNA) used in the front end of a weak signal receiver at a microwave frequency, which can increase the amplitude of the microwave signal. The signal amplifier 203 enhances the microwave signal through the internal overall gain, so that the microwave signal can be effectively transmitted, detected and processed. The signal amplifier 203 is usually composed of a plurality of amplifier cascades, each of which increases the power of the signal to improve the overall gain of the signal amplifier 203. Optionally, the signal amplifier 203 may include, for example: a microwave vacuum tube amplifier, a solid-state microwave device amplifier, a quantum microwave amplifier, and the like.

Thus, the microwave signal is amplified by the signal amplifier 203 with a preset gain to obtain an amplified signal, so that the amplified signal can be received and processed by the signal modulator 204, thereby obtaining an input signal for each antenna. It should be noted that the preset gain of the signal amplifier 203 can be set based on the number of antennas and the preset radiation intensity of each radiation point, which is not limited here.

Furthermore, the control paradigm modulator 201 obtains the position of each antenna in the antenna array, the position of each radiation point in the multiple radiation points of the preset radiation area, and the preset radiation intensity corresponding to each radiation point. Specifically, the control paradigm modulator 201 can use the position of the target antenna in the antenna array as the reference position, and the relative position of each antenna to the target antenna as the position of each antenna. Then, the control paradigm modulator 201 obtains the position of each radiation point in the multiple radiation points of the preset radiation area and the preset radiation intensity corresponding to each radiation point, wherein the preset radiation area, the position of each radiation point, and the preset radiation intensity corresponding to each radiation point can be pre-set by the user on the operating console of the distributed microwave neural control device 200, and the position of each radiation point is the relative position of each radiation point to the target antenna.

Optionally, the preset radiation area may be, for example, a circular area, and the multiple radiation points on the preset radiation area may be, for example, distributed on the boundary and the center of the preset radiation area. For example, four radiation points are set on the boundary of the preset radiation area, and one radiation point is set at the center of the preset radiation area, wherein the four radiation points on the boundary of the preset radiation area may be connected to form a rectangle. It should be noted that the preset radiation area and the position of each radiation point may be independently set based on the needs of neural regulation, and are not limited here.

Exemplarily, when obtaining the position of each antenna in the antenna array and the position of each radiation point in the multiple radiation points of the preset radiation area, the control paradigm modulator 201 establishes a coordinate system with the microwave emission point of the target antenna in the antenna array as the coordinate origin, the signal conduction direction on the target antenna as the horizontal axis, the direction of microwave emission by the target antenna as the vertical axis, and the direction perpendicular to both the horizontal and vertical axes as the longitudinal axis; the coordinates of the microwave emission point of each antenna are obtained, and the coordinates of the microwave emission point of each antenna are used as the position of each antenna; the coordinates of each radiation point in the preset radiation area are obtained, and the coordinates of each radiation point are used as the position of each radiation point.

It should be noted that the target antenna can be any antenna in the antenna array. The microwave emission point of the target antenna is the emission point where the target antenna emits microwaves from the inside of the antenna into the air. The direction of the microwaves emitted by the target antenna is the direction of the central axis of the microwave field formed by the microwaves emitted by the target antenna. In an embodiment of the present application, the signal conduction direction on the target antenna is perpendicular to the direction in which the target antenna emits microwaves. The control paradigm modulator 201 establishes a coordinate system by taking the microwave emission point of the target antenna as the coordinate origin, the signal conduction direction on the target antenna as the horizontal axis direction, the direction in which the target antenna emits microwaves as the vertical axis direction, and the direction perpendicular to both the horizontal axis direction and the vertical axis direction as the longitudinal axis direction.

It can be understood that the embodiments of the present application are only described by taking the establishment of the above-mentioned coordinate system to obtain the position of each antenna and the position of each radiation point as an example. Those skilled in the art can also obtain the relative position of each antenna and each radiation point through other methods, which is not limited here.

Thus, the control paradigm modulator 201 can obtain the coordinates of the microwave emission point of each antenna, that is, the position of each antenna, and the coordinates of each radiation point, that is, the position of each radiation point, by establishing the above-mentioned coordinate system. By obtaining the position of each antenna and the position of each radiation point, the radiation field function from the position of each antenna to the position of each radiation point can be obtained, so as to obtain the field source intensity of each antenna based on the preset radiation intensity of each radiation point, thereby achieving microwave radiation to each radiation point by adjusting the field source intensity of each antenna, thereby improving the accuracy of microwave neural control.

Exemplarily, the control paradigm modulator 201 determines the field source intensity corresponding to each antenna based on the preset radiation intensity corresponding to each radiation point, the position of each radiation point, and the position of each antenna in the antenna array. Specifically, the control paradigm modulator 201 can determine the microwave field formed by the microwaves emitted by each antenna through the position of each radiation point and the position of each antenna in the antenna array obtained as above, thereby determining the radiation intensity variation relationship of each position on the path from the position of each antenna to the position of each radiation point, that is, the radiation field function from the position of each antenna to the position of each radiation point. Thus, based on the preset radiation intensity corresponding to each radiation point and the radiation field function of the radiation point, the field source intensity of each antenna can be determined.

Exemplarily, when determining the field source strength corresponding to each antenna based on the preset radiation intensity corresponding to each radiation point, the position of each radiation point, and the position of each antenna in the antenna array, the control paradigm modulator 201 determines the radiation field function from the position of each antenna to the position of each radiation point based on the position of each radiation point and the position of each antenna; determines the field source strength corresponding to each antenna based on the radiation field function from the position of each antenna to the position of each radiation point, and the preset radiation intensity corresponding to each radiation point.

Specifically, the radiation field function from the position of each antenna to the position of each radiation point can be obtained by simulation on an electromagnetic field simulation model, wherein the electromagnetic field simulation model is a model of the radiation intensity at each position on the microwave field corresponding to a plurality of field source intensities established based on actual measurement results. The control paradigm modulator 201 can determine the radiation intensity at each position on each microwave field based on the electromagnetic conduction parameters and spatial coordinates of the brain tissue by hybrid finite element and boundary element methods. It should be noted that in the embodiment of the present application, since the radiation field function from the position of each antenna to the position of each radiation point is used to represent the radiation intensity at each position on the path from the position of each antenna to the position of each radiation point, the control paradigm modulator 201 only needs to obtain the relative position of each antenna and each radiation point to obtain the radiation field function from the position of each antenna to the position of each radiation point.

Furthermore, after obtaining the radiation field function from the position of each antenna to the position of each radiation point, the control paradigm modulator 201 can determine the field source intensity corresponding to each antenna based on the preset radiation intensity corresponding to each radiation point. Among them, based on the position of each radiation point and the preset radiation intensity of each radiation point, the expected field source intensity of each antenna corresponding to the radiation point can be determined, that is, each antenna can obtain multiple expected field source intensities, and each expected field source intensity corresponds to each radiation point one by one. Based on all the expected field source intensities of each antenna, the field source intensity corresponding to each antenna can be obtained.

Therefore, the control paradigm modulator 201 can determine the field source strength corresponding to each antenna through the above method, and thus determine the input signal corresponding to each antenna based on the field source strength corresponding to each antenna, so that the microwave field formed by the microwaves emitted by each antenna has an intensity of microwaves superimposed at each radiation point that is the preset radiation intensity corresponding to the radiation point, thereby improving the accuracy of microwave neural control.

In a possible embodiment, the relationship between the radiation field function from the position of each antenna to the position of each radiation point, the field source intensity corresponding to each antenna, and the preset radiation intensity of each radiation point can be expressed by the following formula (1):

Formula (1)

in, represents the position of the r-th radiation point, H(r) represents the preset radiation intensity of the r-th radiation point, is the position of the nth antenna in the antenna array, N represents the number of antennas in the antenna array, Indicates the position of the nth antenna To the position of the rth radiant point The radiation field function is It represents the field source strength of the nth antenna, and the rth radiation point is any radiation point.

From formula (1), we can see that the position of the nth antenna is To the position of the rth radiant point The radiation field function can be expressed from the position of the nth antenna To the position of the rth radiant point The relationship between the radiation intensity change at each position in the microwave field. and The product of can be expressed as the field source strength at the nth antenna is When the nth antenna is located at the rth radiation point The radiation intensity of the N antennas is The sum of the radiation intensities of the N antennas can be used to obtain the position of the r-th radiation point. The radiation intensity, that is, the position of the rth radiation point The total radiation intensity. Therefore, when the position of the rth radiation point is set The total radiation intensity is the preset radiation intensity corresponding to the radiation point, and when the radiation field function from the position of each antenna to the radiation point is determined, the field source intensity corresponding to each antenna can be obtained based on formula (1).

Exemplarily, when determining the field source strength corresponding to each antenna based on the radiation field function from the position of each antenna to the position of each radiation point, and the preset radiation intensity corresponding to each radiation point, the control paradigm modulator 201 obtains multiple expected field source intensities corresponding to each antenna based on the radiation field function from the position of each antenna to the position of each radiation point, and the preset radiation intensity corresponding to each radiation point; the average value of the multiple expected field source intensities corresponding to each antenna is used as the field source strength corresponding to each antenna.

In the embodiment of the present application, the control paradigm modulator 201 can obtain the expected field source intensity corresponding to each antenna based on the preset radiation intensity corresponding to the rth radiation point. It can be understood that a plurality of radiation points are set in the preset radiation area. Based on the position of each radiation point and the preset radiation intensity corresponding to the radiation point, the expected field source intensity of all antennas corresponding to each radiation point can be determined, that is, a plurality of expected field source intensities corresponding to each antenna are obtained, and the plurality of expected field source intensities corresponding to each antenna correspond to a plurality of radiation points one by one. Since the field source intensity of each antenna when emitting microwaves is determined, the radiation field function from the position of each antenna to the position of each radiation point is accurate, and there is no calculation error, the plurality of expected field source intensities corresponding to each antenna should all be equal. However, since the radiation field function from the position of each antenna to the position of each radiation point may have an error with the actual radiation field function, the plurality of expected field source intensities corresponding to each antenna may not be completely equal.

To this end, in the embodiment of the present application, the average value of the multiple expected field source intensities corresponding to each antenna is used as the field source intensity corresponding to each antenna to reduce the calculation error of the field source intensity corresponding to each antenna and improve the accuracy of microwave neural regulation. It should be noted that the embodiment of the present application is only described by taking the average value of the multiple expected field source intensities corresponding to each antenna as the field source intensity corresponding to each antenna as an example. Those skilled in the art can also perform other processing on the multiple expected field source intensities corresponding to each antenna to obtain the field source intensity corresponding to each antenna, which is not limited here.

In a possible embodiment, the control paradigm modulator 201 arranges the preset radiation intensity corresponding to each radiation point into a preset radiation intensity matrix. The above formula (1) can be used to obtain the expression of each element in the preset radiation intensity matrix, that is, the preset radiation intensity corresponding to each radiation point can be expressed by formula (1). Therefore, based on the expression of the preset radiation intensity corresponding to each radiation point in the preset radiation intensity matrix, and the preset radiation intensity corresponding to each radiation point, multiple expected field source intensities corresponding to each antenna can be obtained. Therefore, based on the multiple expected field source intensities corresponding to each antenna, the field source intensity corresponding to each antenna is determined. The multiple expected field source intensities corresponding to each antenna can be expressed by the following formula (2):

Formula (2)

Where H(R) represents the R composed of the preset radiation intensities of the R radiation points in the preset radiation area. R is the preset radiation intensity matrix. The elements of each row in H(R) represent the preset radiation intensity corresponding to R radiation points. Each element in the same column in H(R) is equal, representing the preset radiation intensity of the radiation point corresponding to the column. G _E represents the R composed of the radiation field function from each antenna position to each radiation point. N is the radiation field function matrix of G E, where N represents the number of antennas in the antenna array, the elements of each row of G _E represent the radiation field function from the position of each antenna to the position of the radiation point corresponding to the row, and the elements of each column of G _E represent the radiation field function from the position of the antenna corresponding to the column to the position of each radiation point. is the generalization coefficient, I is an N The constant matrix of N, that is is a generalization coefficient matrix, which can be derived from the expression of the preset radiation intensity corresponding to each radiation point in the above preset radiation intensity matrix. M represents the N composed of the R expected field source intensities corresponding to each antenna The expected source strength matrix R, the elements of each row of M represent the R expected source strengths of the antennas corresponding to the row, and the elements of each column of M represent the expected source strengths of the N antennas corresponding to the radiation point corresponding to the column.

It should be noted that since the preset radiation intensity corresponding to each radiation point is obtained by superimposing the radiation intensity of the microwaves emitted by each antenna to the radiation point, the radiation intensity of the microwaves emitted by each antenna to the radiation point is the product of the radiation field function from the position of each antenna to the position of the radiation point and the field source intensity of each antenna. Therefore, when the preset radiation intensity of each radiation point and the radiation field function from the position of each antenna to the position of each radiation point are determined, the control paradigm modulator 201 can obtain multiple expected field source intensities corresponding to each antenna. For example, based on the above R The preset radiation intensity matrix of R and the above R The radiation field function matrix of N can obtain R expected field source intensities corresponding to each antenna, that is, the above-mentioned expected field source intensity matrix. For example, each element of the first row in the expected field source intensity matrix can be determined by the element value of the first column in the preset radiation intensity matrix and each element of the first row in the radiation field function matrix to represent the expected field source intensity of each antenna determined based on the position of the radiation point corresponding to the first row in the expected field source intensity matrix and the preset radiation intensity of the radiation point corresponding to the first row.

Thus, the control paradigm modulator 201 can obtain multiple expected field source strengths corresponding to each antenna, that is, the above-mentioned expected field source strength matrix. Then, the control paradigm modulator 201 averages the elements in each column of the expected field source strength matrix to obtain a 1 N field source strength matrix. Each element in the field source strength matrix represents the field source strength corresponding to each antenna. It should be noted that the elements in each column of the expected field source strength matrix represent multiple expected field source strengths of the antenna corresponding to the column, that is, the expected field source strength of the antenna corresponding to the column determined based on the position of each radiation point and the preset radiation intensity of each radiation point. The control paradigm modulator 201 averages each column in the expected field source strength matrix and uses the average of each column in the expected field source strength matrix as the field source strength of the antenna corresponding to the column.

It can be seen that in the embodiment of the present application, the control paradigm modulator determines the radiation field function from the position of each antenna to the position of each radiation point based on the position of each radiation point and the position of each antenna, thereby obtaining multiple expected field source intensities corresponding to each antenna based on the radiation field function from the position of each antenna to the position of each radiation point and the preset radiation intensity corresponding to each radiation point, and taking the average value of the multiple expected field source intensities corresponding to each antenna as the field source intensity corresponding to each antenna. Thus, the field source intensity of each antenna can be determined, so as to control each antenna to emit microwaves of the field source intensity corresponding to the antenna, and perform microwave neural regulation on the subject, thereby improving the accuracy of microwave neural regulation.

Furthermore, the signal modulator 204 modulates the input signal of each antenna based on the amplified signal and the field source strength corresponding to each antenna, so as to control the intensity of the microwaves emitted by each antenna to be the field source strength corresponding to the antenna through the input signal of each antenna, so that the intensity of the microwave field formed by the microwaves emitted by each antenna superimposed at each radiation point is the preset radiation intensity corresponding to the radiation point.

Specifically, the control paradigm modulator 201 can send the field source strength corresponding to each antenna to the signal modulator 204, so as to modulate the input signal corresponding to the field source strength of each antenna through the signal modulator 204. After receiving the field source strength corresponding to each antenna, the signal modulator 204 performs dispersed modulation on the amplified signal, and modulates it into the input signal of each antenna respectively, so as to make the intensity of the microwave emitted by each antenna to be the field source strength corresponding to the antenna through the input signal of each antenna. It should be noted that the signal modulator 204 only modulates the intensity of the amplified signal to modulate the intensity of each antenna input signal, so that the intensity of each antenna input signal corresponds to the field source strength of the antenna.

Exemplarily, when the input signal of each antenna is modulated based on the amplified signal and the field source strength corresponding to each antenna, the signal modulator 204 separates the amplified signal into multiple modulation signals; determines the amplitude of the input signal of each antenna based on the field source strength corresponding to each antenna; modulates the amplitude of the modulation signal corresponding to each antenna into the amplitude of the input signal corresponding to the antenna, and obtains the input signal corresponding to each antenna. It should be noted that each modulation signal in the multiple modulation signals corresponds to each antenna one by one.

Specifically, the signal modulator 204 separates the amplified signal to obtain multiple modulated signals, each of which corresponds to each antenna. Optionally, the amplified signal can be evenly divided into multiple modulated signals based on the amplitude of the amplified signal. For example, when the number of antennas is N and the amplitude of the amplified signal is A, the amplified signal can be separated into N modulated signals, and the amplitude of each modulated signal is A/N. Then, based on the field source strength corresponding to each antenna, the signal modulator 204 can determine the amplitude of the input signal of each antenna, and modulate the amplitude of the modulated signal corresponding to each antenna to the amplitude of the input signal corresponding to the antenna, to obtain the input signal corresponding to each antenna.

Optionally, the signal modulator 204 may also modulate the frequency of the modulation signal corresponding to each antenna, so that the frequency of the microwaves emitted by each antenna is the same as the frequency of the modulation signal corresponding to each antenna, which is not limited in this embodiment of the present application.

It can be seen that the signal modulator 204 separates the amplified signal into multiple modulated signals, and determines the amplitude of the input signal of each antenna based on the field source strength corresponding to each antenna, and then modulates the amplitude of the modulated signal corresponding to each antenna to the amplitude of the input signal corresponding to the antenna, thereby obtaining the input signal corresponding to each antenna. Thus, the signal modulator 204 can provide each antenna with the input signal corresponding to the antenna, so that the intensity of the microwaves emitted by each antenna is the field source strength corresponding to the antenna, so that the radiation intensity at each radiation point is the preset radiation intensity of the radiation point, thereby improving the accuracy of microwave neural regulation.

Exemplarily, when determining the amplitude of the input signal of each antenna based on the field source strength corresponding to each antenna, the signal modulator 204 obtains the radiation efficiency of each antenna; determines the amplitude of the electromagnetic signal corresponding to each antenna based on the field source strength corresponding to each antenna and the radiation efficiency of each antenna; and determines the amplitude of the input signal of each antenna based on the amplitude of the electromagnetic signal corresponding to each antenna.

Specifically, each antenna can be used to convert an input alternating current signal into an electromagnetic signal of a specific frequency. The input signal of each antenna in the embodiment of the present application is an input alternating current signal, and each antenna in the embodiment of the present application transmits the above electromagnetic signal into the air to form a microwave. Among them, the input signal of each antenna forms an electromagnetic signal through oscillation on the antenna, and is transmitted into the air through the microwave emission point of the antenna. During the transmission process, the electromagnetic signal on each antenna will have energy attenuation, that is, the field source intensity of the microwave emitted by each antenna is less than the intensity of the electromagnetic signal formed on the antenna. The ratio of the field source intensity of the microwave emitted by each antenna to the intensity of the electromagnetic signal formed on the antenna is the radiation efficiency of each antenna.

To this end, in an embodiment of the present application, the signal modulator 204 obtains the radiation efficiency of each antenna to obtain the ratio of the field source intensity of the microwave emitted by each antenna to the intensity of the electromagnetic signal formed on the antenna. Based on each corresponding field source intensity and the radiation efficiency of each antenna, the amplitude of the electromagnetic signal corresponding to each antenna can be determined, that is, the amplitude of the electromagnetic signal actually formed on each antenna. Then, based on the amplitude of the electromagnetic signal corresponding to each antenna, the amplitude of the input signal of each antenna can be determined. It should be noted that the preset gain of each antenna to convert the input signal into an electromagnetic signal is determined by the circuit structure of each antenna. To this end, the signal modulator 204 can determine the amplitude of the input signal of the antenna based on the amplitude of the electromagnetic signal corresponding to each antenna and the preset gain of the antenna to convert the input signal into an electromagnetic signal.

Optionally, each antenna may be provided with a plurality of preset gains, and the antenna input signal may be transmitted to the signal path of each preset gain through the selection switch inside the antenna to form an electromagnetic signal of an amplitude corresponding to each preset gain. The signal modulator 204 may obtain the preset gain corresponding to the input signal of each antenna to determine the amplitude of the input signal of each antenna based on the amplitude of the electromagnetic signal corresponding to each antenna.

Therefore, the signal modulator 204 can determine the amplitude of the electromagnetic signal corresponding to each antenna based on the field source strength corresponding to each antenna and the radiation efficiency of each antenna, and determine the amplitude of the input signal of each antenna based on the amplitude of the electromagnetic signal corresponding to each antenna, so as to modulate the amplitude of the input signal of each antenna so that the intensity of the microwave emitted by the antenna is the field source strength corresponding to the antenna, and then the radiation intensity at each radiation point is the preset radiation intensity of the radiation point, thereby improving the accuracy of microwave neural regulation.

In one possible embodiment, each antenna may include multiple microstrip antennas. The input signal of each antenna includes a sub-input signal of each microstrip antenna of the antenna. When determining the amplitude of the input signal of each antenna based on the field source strength corresponding to each antenna, the signal modulator 204 obtains the position of each microstrip antenna; determines the sub-field source strength of each microstrip antenna of each antenna based on the field source strength corresponding to each antenna and the position of each microstrip antenna of the antenna; and determines the amplitude of the sub-input signal of each microstrip antenna of each antenna based on the sub-field source strength of each microstrip antenna of each antenna.

Exemplarily, as shown in FIG3, each antenna may include 2 corresponding to the antenna. 2 microstrip antenna array, where each 2 The microwaves emitted by the microstrip antenna array 2 can be superimposed to form a microwave field as shown in Figure 3. The superimposed microwave field is the microwave field formed by the microwaves emitted by each transmitting antenna. The field source strength of the microwaves emitted by each transmitting antenna is determined by the position of each microstrip antenna of the antenna and the sub-field source strength of the microwaves emitted by each microstrip antenna.

Therefore, the signal modulator 204 obtains the coordinates of the microwave emission point of each microstrip antenna and uses the coordinates of the microwave emission point of each microstrip antenna as the position of each microstrip antenna. The position of each microstrip antenna determines the direction of the microwaves emitted by each antenna. Then, based on the field source strength corresponding to each antenna and the position of each microstrip antenna of the antenna, the sub-field source strength of each microstrip antenna of each antenna is determined. It should be noted that when the position of each microstrip antenna is determined, the field source strength of the microwaves emitted by each antenna corresponds to the sub-field source strength of each microstrip antenna of the antenna. Thus, the sub-field source strength of each microstrip antenna of each antenna can be determined, and thus the amplitude of the sub-input signal of each microstrip antenna of each antenna can be determined based on the sub-field source strength of each microstrip antenna of each antenna.

In the embodiment of the present application, the method of determining the amplitude of the sub-input signal of each microstrip antenna of each antenna based on the sub-field source strength of each microstrip antenna of each antenna is similar to the method of determining the amplitude of the input signal of each antenna based on the field source strength corresponding to each antenna in the above-mentioned embodiment, and will not be repeated here.

It can be seen that the signal modulator 204 can obtain the position of each microstrip antenna, determine the sub-field source strength of each microstrip antenna of each antenna based on the field source strength corresponding to each antenna and the position of each microstrip antenna, and determine the amplitude of the sub-input signal of each microstrip antenna of each antenna based on the sub-field source strength of each microstrip antenna of each antenna, so that the microwave fields formed by multiple microstrip antennas corresponding to each antenna are superimposed as the microwave field corresponding to the antenna, so as to perform microwave neural regulation on the subject, thereby improving the accuracy of microwave neural regulation.

Finally, each antenna emits microwaves to the preset radiation area, and the intensity of the microwaves emitted by each antenna is the field source intensity corresponding to the antenna. The microwave field formed by the microwaves emitted by each antenna is superimposed in the preset radiation area to radiate the preset radiation area, wherein the radiation intensity at each radiation point is the preset radiation intensity corresponding to the radiation point, thereby radiating microwaves to the preset radiation area of the subject's brain to inhibit the signal conduction of neurons in the preset radiation area.

To summarize, in an embodiment of the present application, when microwave nerve regulation is performed on a subject, a microwave signal is generated by controlling a signal generator through a regulation paradigm modulator, and a signal amplifier amplifies the microwave signal to obtain an amplified signal. Then, the position of each antenna in the antenna array, the position of each radiation point in a plurality of radiation points in a preset radiation area, and the preset radiation intensity corresponding to each radiation point are obtained through a regulation paradigm modulator, thereby determining the field source strength corresponding to each antenna based on the preset radiation intensity corresponding to each radiation point, the position of each radiation point, and the position of each antenna in the antenna array. The signal modulator modulates the amplified signal into an input signal for each antenna based on the field source strength corresponding to each antenna, so as to control the intensity of the microwaves emitted by each antenna to be the field source strength of the antenna through the input signal of each antenna, so that the intensity of the microwave field formed by the microwaves emitted by each antenna superimposed at each radiation point is the preset radiation intensity corresponding to the radiation point. Therefore, the microwave field formed by the microwaves emitted by multiple antennas of the above-mentioned distributed microwave neural regulation device can be superimposed in the preset radiation area, and the radiation intensity of the superimposed microwave field to each radiation point is the preset radiation intensity corresponding to the radiation point, which solves the problem of attenuation in the process of microwave radiation to the preset radiation area, resulting in low radiation intensity in the preset radiation area, and improves the accuracy of microwave neural regulation. Since the radiation intensity of each radiation point is obtained by superimposing the radiation intensity of multiple antennas, the radiation intensity of the microwave field formed by the microwaves emitted by each antenna is low, and the microwave field corresponding to each antenna generates low radiation to other areas of the brain, which reduces the impact of microwave radiation on other brain tissues and further improves the accuracy of microwave neural regulation.
