The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

An embodiment of the present invention provides an ultrasound imaging system, referring to fig. 1-2, comprising an ultrasound probe and an ultrasound device; the ultrasonic probe is provided with a sound head sensor 1 and a gesture sensor 2, wherein the sound head sensor 1 is used for acquiring ultrasonic imaging data, and the gesture sensor 2 is used for acquiring motion gesture data; at least one of the ultrasonic probe and the ultrasonic equipment is internally provided with a gesture analysis module 3, and the gesture analysis module 3 is connected with the gesture sensor 2 and is used for determining a probe working section corresponding to the ultrasonic probe according to the motion gesture data; an imaging control module 4 is arranged in at least one of the ultrasonic probe and the ultrasonic equipment, and the imaging control module 4 is connected with the sound head sensor 1 and the gesture analysis module 3 and is used for generating an original ultrasonic image according to ultrasonic imaging data and controlling imaging frame rate according to a probe working section corresponding to the ultrasonic probe.

Wherein, the ultrasonic imaging data is data for generating an ultrasonic image acquired by the sound head sensor 1 of the ultrasonic probe in real time. As an example, the ultrasound probe may be controlled to emit ultrasound waves to human tissue by the imaging control module 4 provided on the ultrasound probe and/or the ultrasound apparatus, receive ultrasound waves transmitted in a medium such as human tissue by the sound head sensor 1, generate ultrasound imaging data such as reflected waves and scattered waves, and transmit the ultrasound imaging data to the imaging control module 4, so that the imaging control module 4 may generate an original ultrasound image from the ultrasound imaging data. In this example, the ultrasonic probe may be composed of a plurality of elongated piezoelectric transducers (each single piezoelectric transducer is called an array element) with the same size and arranged at equal intervals; or the piezoelectric transducers are arranged in a two-dimensional array, i.e. array elements are arranged in a two-dimensional matrix shape. The piezoelectric transducer in the ultrasonic probe converts the voltage pulse excitation applied to the piezoelectric transducer into mechanical vibration, so that ultrasonic waves are emitted outwards; the ultrasonic wave propagates in the medium such as human tissue, and echo analog signals such as reflected waves and scattered waves are generated, each piezoelectric transducer can convert the echo analog signals into echo electric signals, amplify and analog-to-digital convert the echo electric signals, and transmit ultrasonic imaging data converted into echo digital signals to the imaging control module 4. The imaging control module 4 may receive the ultrasonic imaging data, such as echo digital signals, and perform imaging control operations such as beam forming, modulo, logarithmic compression, and spatial compounding on the echo digital signals of one or more channels to generate an original ultrasonic image. The data analysis is to analyze the echo synthesized signals into a two-dimensional matrix of the number of sampling points multiplied by the number of scanning lines, but the signals at each position are complex signals, and in order to image more intuitively, the complex signals are subjected to modulo operation to obtain the energy of the signals, and the energy is used for representing the signals at the position. The logarithmic compression is to make a logarithmic function transformation on the data after the modulo operation, and compress the dynamic range to make the organization level of the image clearer. After that, the same area image transmitted and received at a plurality of angles is compounded by using a space compounding operation, so that the coherence effect is weakened, the speckle noise is reduced, and the resolution of the whole image is improved.

As an example, during the movement of the ultrasonic probe, the gesture sensor 2 built in the ultrasonic probe may collect motion gesture data in real time and send the motion gesture data to the gesture analysis module 3, so that the gesture analysis module 3 analyzes the motion gesture data to determine a probe working section corresponding to the ultrasonic probe, where the probe working section may be an effective imaging section or an ineffective imaging section, when the ultrasonic probe is in a working scanning state, the probe working section corresponding to the ultrasonic probe is an effective imaging section, and when the probe is in an inactive scanning state, the probe working section corresponding to the ultrasonic probe is an ineffective imaging section.

In this example, the gesture analysis module 3 may be implemented by an upper computer CPU algorithm module, may be implemented by a special processor (such as a DSP, an FPGA, etc.), may also be implemented by a digital signal processing module integrated inside the sensor, and the algorithm implementation is simple, so as to save the operation resources of the FPGA.

As an example, in step S1, the imaging controller obtains ultrasonic imaging data corresponding to the ultrasonic probe through the sound head sensor 1 integrated on the ultrasonic probe and obtains motion gesture data corresponding to the ultrasonic probe through the gesture sensor 2 integrated on the ultrasonic probe, that is, obtains real-time motion information and gesture information of the ultrasonic probe during the operation of the ultrasonic probe. For example, as a probe sound head position or a motion sensor (sensing array), the gesture sensor 2 generally monitors acceleration and rotation angular velocity of each ultrasonic probe sound head direction in real time by using a gyroscope(s) for acquiring motion gesture data of the ultrasonic probe, wherein the motion gesture data includes three-axis acceleration and three-axis angular velocity, namely X-direction acceleration, Y-direction acceleration and Z-direction acceleration, and X-direction angular velocity, Y-direction angular velocity and Z-direction angular velocity.

As an example, in step S2, the imaging controller determines a probe working section corresponding to the ultrasonic probe according to the motion gesture data, specifically, analyzes motion gesture data such as triaxial acceleration and triaxial angular velocity of the ultrasonic probe provided by the gesture sensor, and determines motion gesture changes between different moments according to the motion gesture data acquired at different moments, so as to determine the probe working section corresponding to the ultrasonic probe according to the motion gesture changes at different moments.

As an example, in step S3, the imaging controller generates an original ultrasound image according to the ultrasound imaging data, and specifically performs imaging control operations such as beam forming, modulo, logarithmic compression, and spatial compounding on the ultrasound imaging data, which is the received echo digital signal, to generate the original ultrasound image; and the imaging frame rate control is carried out according to the probe working section corresponding to the ultrasonic probe which is determined by analyzing the motion gesture data, so that the imaging control and the motion gesture data of the ultrasonic equipment are fused, and the intelligent control of the ultrasonic imaging scanning and processing part of the equipment is realized. The gesture analysis module 3 integrated on the ultrasonic probe is used for identifying an effective imaging section of the ultrasonic probe, and an identification result is input into the related imaging control module 4; an imaging control module 4 integrated on the ultrasound device controls the imaging frame rate of the ultrasound device in accordance with the identified probe working section in combination with different working scenarios. For example, the gesture analysis module 3 integrated on the ultrasonic probe can be used for judging that the ultrasonic probe moves rapidly, the probe working section opposite to the ultrasonic probe is in an ineffective imaging section, and the processing result is transmitted to the imaging control module 4 of the ultrasonic equipment in real time, and the imaging control module 4 integrated on the ultrasonic equipment can reduce the imaging frame rate of the ultrasonic equipment, so that the overall power consumption of the equipment is reduced.

In this embodiment, the motion gesture data of the ultrasonic probe by using the gesture sensor 2 is combined with a specific use scenario of the ultrasonic device, especially the spatial gesture of the ultrasonic probe, to determine the use position state of the ultrasonic probe, so as to optimize the user operation. For example, when the posture sensor 2 detects that the ultrasonic probe points downwards from top to bottom, the current ultrasonic probe checks that the part of the patient does not have an application scene of the probe state, and the imaging control module 4 can reduce the frame rate of the imaging control of the device or directly freeze the image through scanning control; the user can define various desired control instructions by inputting a specific custom gesture by himself.

In an embodiment, referring to fig. 4, step S2, that is, determining a probe working section corresponding to the ultrasonic probe according to the motion gesture data, includes:

s211: determining the gesture change rate corresponding to the ultrasonic probe according to the motion gesture data;

s212: if the gesture change rate is greater than a preset rate threshold, determining that a probe working section corresponding to the ultrasonic probe is an invalid imaging section;

s213: and if the gesture change rate is not greater than the preset rate threshold, determining that the probe working section corresponding to the ultrasonic probe is an effective imaging section.

The preset speed threshold is a speed value which is set according to actual conditions and used for judging the gesture change speed corresponding to the ultrasonic probe.

As an example, in step S211, the imaging controller collects motion gesture data of the ultrasonic probe through the gesture sensor 2 integrated on the ultrasonic probe, and calculates and determines a gesture change rate corresponding to the ultrasonic probe according to the motion gesture data, where the gesture change rate may calculate a difference between the two according to the motion gesture data between the two moments, and calculate a difference between the two and a corresponding time difference to determine a gesture change rate corresponding to the difference. For example, as a probe sound head position or a motion sensor (sensing array), the gesture sensor 2 generally adopts a gyroscope(s) to monitor acceleration and rotation angular velocity of each ultrasonic probe sound head direction in real time, so as to acquire motion gesture data of the ultrasonic probe.

As an example, in step S212, the imaging controller may compare the calculated posture change rate corresponding to the ultrasonic probe with a preset rate threshold, and determine that the ultrasonic probe is in a fast moving process when the posture change rate corresponding to the ultrasonic probe is greater than the preset rate threshold, where the process has a high probability of being a process of searching for a diagnostic position, rather than a process of performing ultrasonic scanning on the diagnostic position, and thus may determine that the probe working section corresponding to the ultrasonic probe is an ineffective imaging section.

As an example, in step S213, the imaging controller may compare the calculated gesture change rate corresponding to the ultrasound probe with a preset speed threshold, and determine that the movement speed of the ultrasound probe is slower when the gesture change rate corresponding to the ultrasound probe is not greater than the preset speed threshold, and the maximum probability is that the ultrasound scanning process is performed for the diagnostic position, so that the probe working section corresponding to the ultrasound probe may be determined to be an effective imaging section.

In this embodiment, the imaging controller calculates the gesture change rate of the ultrasonic probe in real time according to the motion gesture data of the gesture sensor 2 integrated on the ultrasonic probe, and determines whether the ultrasonic probe is in the fast moving process based on the comparison result of the gesture change rate and the preset speed threshold, so as to determine that the probe working section corresponding to the ultrasonic probe is an ineffective imaging section or an effective imaging section, so that the imaging rate of the ultrasonic probe is controlled in the effective imaging section based on the finally determined probe working section, so as to achieve the purposes of not scanning in the ineffective imaging section and reducing power consumption.

In one embodiment, referring to FIG. 5, the motion gesture data includes tri-axial acceleration and tri-axial angular velocity;

Step S2, namely determining the gesture change rate corresponding to the ultrasonic probe according to the motion gesture data, wherein the step comprises the following steps:

s221: according to the triaxial acceleration and the triaxial angular velocity, respectively determining the acceleration change rate and the angular velocity change rate corresponding to the ultrasonic probe;

s222: if any one of the acceleration change rate and the angular velocity change rate is larger than a preset rate threshold, determining that a probe working section corresponding to the ultrasonic probe is an ineffective imaging section;

s223: and if the acceleration change rate and the angular velocity change rate are not greater than the preset rate threshold, determining that the probe working section corresponding to the ultrasonic probe is an effective imaging section.

Step S221 is an embodiment of step S211, step S222 is an embodiment of step S212, and step S223 is an embodiment of step S223.

The motion gesture data comprises three-axis acceleration and three-axis angular velocity, wherein the three-axis acceleration comprises X-direction acceleration, Y-direction acceleration and Z-direction acceleration, and the three-axis angular velocity comprises X-direction angular velocity, Y-direction angular velocity and Z-direction angular velocity. The preset speed threshold is a speed value which is preset according to actual conditions and used for judging the gesture change speed corresponding to the ultrasonic probe.

As an example, in step S221, the imaging controller acquires X-direction acceleration, Y-direction acceleration, and Z-direction acceleration of the ultrasonic probe at different moments through the attitude sensor 2 integrated on the ultrasonic probe, and acquires X-direction angular velocity, Y-direction angular velocity, and Z-direction angular velocity; and then, determining the acceleration change rate corresponding to the ultrasonic probe according to the X-direction acceleration, the Y-direction acceleration and the Z-direction acceleration corresponding to different moments, and determining the angular velocity change rate corresponding to the ultrasonic probe according to the X-direction angular velocity, the Y-direction angular velocity and the Z-direction angular velocity corresponding to different moments. For example, as a probe sound head position or a motion sensor (sensing array), the gesture sensor 2 generally adopts a gyroscope(s) to monitor acceleration and rotation angular velocity of each ultrasonic probe sound head direction in real time, so as to acquire motion gesture data of the ultrasonic probe.

As an example, in step S222, the acceleration change rate and the angular velocity change rate corresponding to the ultrasonic probe may be used as variables for determining the operation state of the ultrasonic probe, and when one of the acceleration change rate and the angular velocity change rate is changed, the other is also changed, so that either one of the acceleration change rate and the angular velocity change rate changes, and the operation state of the ultrasonic probe is affected, so that whether the probe operation section is effective or not can be determined. When any one of the acceleration change rate and the angular velocity change rate corresponding to the ultrasonic probe is larger than a preset rate threshold value, the imaging controller determines that any one of the acceleration and the angular velocity of the ultrasonic probe is in a rapid change state, and the maximum probability is a process of searching for a diagnosis position and not a process of performing ultrasonic scanning on the diagnosis position, so that a probe working section corresponding to the ultrasonic probe can be determined to be an ineffective imaging section;

As an example, in step S223, when the acceleration change rate and the angular velocity change rate corresponding to the ultrasound probe are not greater than the preset rate threshold, the imaging controller determines that the acceleration change and the angular velocity change of the ultrasound probe are slower, and the maximum probability is that the ultrasound scanning is performed on the diagnostic position, so that the probe working section corresponding to the ultrasound probe may be determined to be an effective imaging section.

In this embodiment, the imaging controller collects the triaxial acceleration and triaxial angular velocity of the ultrasonic probe through the attitude sensor 2 integrated on the ultrasonic probe, and determines the acceleration change rate and the angular velocity change rate corresponding to the ultrasonic probe according to the triaxial acceleration and the triaxial angular velocity at different moments, and compares and judges the acceleration change rate and the angular velocity change rate corresponding to the ultrasonic probe with a preset rate threshold through the attitude analysis module 3 integrated in the imaging controller, so as to determine the probe working section corresponding to the ultrasonic probe according to the comparison result.

In one embodiment, step S3, that is, performing imaging frame rate control according to a probe working section corresponding to the ultrasound probe, includes:

s31: if the probe working section corresponding to the ultrasonic probe is an invalid imaging section, reducing the imaging frame rate of the ultrasonic probe;

S32: if the probe working section corresponding to the ultrasonic probe is an effective imaging section, determining a current working scene based on the current scene image, and adjusting the imaging frame rate of the ultrasonic probe based on the current working scene.

The current scene image refers to a scene image shot at the moment, and may be an image acquired by a camera or other devices during the working process of the ultrasonic probe held by a user (i.e. doctor). The current working scene refers to the working scene of the current moment of the user identified according to the current scene image, and the current working scene can be any one of searching for a diagnosis position scene or scanning the diagnosis position scene.

As an example, the imaging controller identifies the probe working section corresponding to the ultrasonic probe through the integrated imaging control module 4, and performs imaging frame rate control according to the result of identifying the probe working section corresponding to the ultrasonic probe, when the probe working section corresponding to the ultrasonic probe is an ineffective imaging section, which indicates that the ultrasonic probe is not in the ultrasonic scanning process for the diagnosis position of human tissue at the moment, the imaging frame rate of the ultrasonic probe is reduced, so as to achieve the purpose of reducing the power consumption of the ultrasonic probe; when the probe working section corresponding to the ultrasonic probe is an effective imaging section, the ultrasonic probe is possibly in an ultrasonic scanning process for the diagnosis position of human tissues or is not possibly in an ultrasonic scanning process for the diagnosis position of human components, at the moment, a current scene image is required to be acquired through a camera or other equipment, then the current scene image is identified by adopting a pre-trained neural network model so as to determine a current working scene corresponding to the current scene image, and the current working scene can reflect the specific scene of the user currently in searching for the diagnosis position or scanning the diagnosis position so as to adjust the imaging frame rate of the ultrasonic probe based on the current working scene, thereby achieving the purpose of reducing power consumption.

In this embodiment, the imaging controller may identify the motion gesture data by using the integrated gesture analysis module 3, determine a probe working section corresponding to the ultrasonic probe, and input the probe working section corresponding to the ultrasonic probe into the imaging control module 4; the imaging controller reuses the integrated imaging control module 4 to control the frame rate control of the imaging of the ultrasonic equipment according to the identified working section of the probe and combining different working scenes. Specifically, the gesture analysis module 3 integrated on the ultrasonic probe by the imaging controller judges that the ultrasonic probe moves rapidly, when the ultrasonic probe is determined to be in an ineffective imaging section, the processing result is transmitted to the imaging control module 4 integrated on the ultrasonic equipment in real time, and the imaging controller controls the ultrasonic equipment to reduce the frame rate of imaging of the ultrasonic equipment, so that the overall power consumption of the equipment is reduced. The gesture analysis module 3 integrated on the ultrasonic probe by the imaging controller judges that the ultrasonic probe moves rapidly, and when the ultrasonic probe is determined to be in an effective imaging section, the current working scene of the ultrasonic probe needs to be determined according to the current scene image acquired in real time, so that imaging frame rate control is performed based on the current working scene, and the purpose of reducing power consumption is achieved. In this example, the imaging controller can realize imaging control of the ultrasonic equipment and data fusion of real-time motion state and gesture information of the ultrasonic probe through the gesture analysis module 3 integrated on the ultrasonic probe and the imaging control module 4 integrated on the ultrasonic equipment, so as to realize intelligent control of the ultrasonic imaging scanning and processing part of the equipment.

In an embodiment, step S32, that is, adjusting the imaging frame rate of the ultrasound probe according to the current working scenario, includes:

s321: if the current working scene is the scene for searching the diagnosis position, reducing the imaging frame rate of the ultrasonic probe;

s322: and if the current working scene is a scanning diagnosis position scene, the imaging frame rate of the ultrasonic probe is improved.

As an example, a user selects an ultrasonic probe according to a diagnosis position, the ultrasonic probe selects the ultrasonic probe, then determines the position to be diagnosed, then acquires a current scene image through a camera or other equipment, and adopts a pre-trained neural network model to identify a user moving path and a gesture in the current scene image so as to determine a current working scene according to the change of the user moving path and the gesture. When the imaging controller monitors that the moving path is rapid and disordered and the gesture is continuously changed, the fact that the final diagnosis position is not determined at the moment is indicated, and the current working scene is determined to be the scene for searching the diagnosis position is determined, so that the imaging frame rate of the ultrasonic probe needs to be reduced, and the purpose of reducing the power consumption is achieved. When the imaging controller monitors that the moving path is slow and orderly and the gestures remain unchanged, the method indicates that the maximum probability is that the diagnosis position is determined, and ultrasonic scanning is carried out on the diagnosis position, at the moment, the imaging frame rate of the ultrasonic probe needs to be improved to acquire more effective image features, so that the final imaging effect is ensured.

In this embodiment, when determining that the working section of the probe is an effective imaging section according to the motion gesture data, the current working scene of the object needs to be further determined by combining with the current scene image, so as to control the frame rate control of imaging of the ultrasonic device, and both the power consumption and the imaging quality of the ultrasonic imaging system can be considered.
