Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

Fig. 1 is a schematic flowchart of an ultrasound imaging method provided by an embodiment of the application. As shown in Fig. 1, the method may specifically include:

S101. Transmit an ultrasonic group at least twice at a target position on the scanning plane.

S102. Acquire ultrasonic echo data at various positions on the scanning plane.

S103. Obtain multiple ultrasound images according to the acquired ultrasound echo data. This embodiment respectively introduces the specific implementation manners of each of the above steps, as follows:

Specifically, the target position is any position on the scanning plane. Wherein, the scanning plane is a plane formed by the ultrasonic transmitting probe of the ultrasound equipment, and the target position can be any pulse emission position in the scanning plane of the scanning equipment. The ultrasound group includes a first type of ultrasound and a second type of ultrasound, wherein at least one of the amplitude and phase of the first type of ultrasound and the second type of ultrasound is different.

Optionally, the ultrasound group transmitted at any one time may include the following three situations:

The first type: the first type of ultrasound and the second type of ultrasound have the same amplitude and different phases;

The second type: the first type of ultrasound and the second type of ultrasound have different amplitudes and the same phase;

The third type: the first type of ultrasonic waves and the second type of ultrasonic waves have different amplitudes and different phases.

This step describes the two optional transmission methods with reference to Figure 2a and Figure 2b. In Figure 2a and Figure 2b, the horizontal coordinate represents the time sequence, and the vertical coordinate represents the amplitude. The solid arrow represents each ultrasonic pulse, the sign "+" indicates that the phase of the ultrasonic wave is positive, and the sign "-" indicates that the phase of the ultrasonic wave is negative.

Figure 2a illustrates a schematic diagram of the emission sequence of the first ultrasonic group. As shown in FIG. 2a, the first transmission method transmits an ultrasonic group N (N≥2) times, and the ultrasonic group transmitted at any one time includes two ultrasonic waves of the first type and one ultrasonic wave of the second type. Wherein, the amplitude of the first type of ultrasonic waves is smaller than the amplitude of the second type of ultrasonic waves, and the phase of the first type of ultrasonic waves is negative, and the phase of the second type of ultrasonic waves is positive. The ultrasonic pulses in the ultrasonic group emitted at any one time illustrated in Fig. 2a can be summarized as [-a,1,-a], 0<a<1.

Figure 2b illustrates a schematic diagram of the second type of ultrasound group's emission sequence. As shown in Fig. 2b, the second transmission method emits an ultrasonic group M (M≥2) times, and the ultrasonic group emitted at any one time includes one first-type ultrasonic wave and one second-type ultrasonic wave. Wherein, the amplitude of the first type of ultrasonic waves is smaller than the amplitude of the second type of ultrasonic waves, and the phase of the first type of ultrasonic waves is negative, and the phase of the second type of ultrasonic waves is positive. The ultrasonic pulses in the ultrasonic group emitted at any one time illustrated in Fig. 2b can be summarized as [-a,1], 0<a<1.

It should be noted that this embodiment does not limit the specific amplitude and phase of the emitted ultrasound. The specific implementation of the above two emission methods is only an example. The ultrasound imaging method provided in this application may also include other ultrasound group emission methods. Various specific implementation manners, for example, the phase of the first type of ultrasound and the phase of the second type of ultrasound in any ultrasound group are both positive, and the amplitude of the first type of ultrasound is greater than the amplitude of the second type of ultrasound. Regarding this, the embodiments of the present application will not go into details.

Optionally, at the target position, the pulse is transmitted according to a preset pulse repetition frequency (denoted as PRF), which is a user-adjustable parameter. The time interval between the two ultrasound pulses emitted on the scanning plane is defined as LetTime, which is determined by the imaging depth of the image and the parameter loading time of the system, and is mainly determined by the imaging depth adjusted by the user. The LetTime must be less than 1/PRF .

In this embodiment, transmitting the ultrasonic group at the target position includes two optional ultrasonic transmission methods, as follows:

The first type, the ultrasonic group emitted from the target position on the scanning plane, is emitted in a plane wave mode.

Transmitting ultrasonic waves in plane wave mode, all array elements in the scanning plane emit ultrasonic pulses at the same time. Obviously, in this mode, the entire area to be imaged can be scanned by a single shot of ultrasound. Among them, the relationship between the array element and the position is: array element number * array element spacing = position coordinates.

The second is that the ultrasonic waves emitted from the target position on the scanning plane are emitted in the form of focused waves.

Specifically, the process of transmitting ultrasound in the form of a focused wave is: according to the preset PRF, the target imaging depth depth, the target imaging width Width (range 0 to 1.0), and the number of beams R of the ultrasound imaging system, calculate the target imaging Under the width Width and the target imaging depth depth, the sweep size that can be scanned by one focus wave emission, and further, the number of volume data packets (packet size) is calculated, that is, how many times the focus wave needs to be emitted to obtain a frame of image by scanning.

For example, it is calculated that sweep size=4, and the entire target imaging width Width in the scanning plane requires 16 shots, and 16/4=4 focused waves need to be emitted to complete the scan of the entire imaging range.

It should be noted that if the scanning plane requires 18 transmissions, it is necessary to transmit ceil(18/4)=5 individual data packets to complete the scanning of the entire imaging range. At this time, the extra 2 transmitted will eventually be The received data of the beams are all discarded in the subsequent processing, and ceil means rounding up.

S102. Acquire ultrasonic echo data at various positions on the scanning plane.

The echo data of the ultrasound group at the target position includes the echo data of the first type of ultrasound and the echo data of the second type of ultrasound. Because the amplitude and phase of the first type of ultrasound and the second type of ultrasound are transmitted At least one item of is different, so that at least one of the amplitude and phase of the echo data of the first type of ultrasonic waves is different from the echo data of the second type of ultrasonic waves.

Wherein, echo data of ultrasonic waves with at least one of different amplitude and phase can be used to obtain a contrast ultrasound image.

In addition, the echo data of ultrasound waves transmitted in different groups with the same amplitude and phase can be used to obtain a blood flow ultrasound image, and can also be used to obtain at least one of an energy Doppler ultrasound image and a blood flow variance ultrasound image.

Furthermore, the echo data of ultrasonic waves whose amplitude and phase are the same in different groups can also be used to obtain tissue gray-scale ultrasound images.

Further, when the ultrasonic waves emitted from different positions on the scanning plane are emitted in plane waves, or in focused waves and the number of volume data packets is one, one emission is used to scan the entire area to be imaged. At this time, In this method, the ultrasound group can be set to transmit at least 64 times, and the acquired echo data of the ultrasound group can also be used to obtain a spectral Doppler ultrasound image.

Taking the echo data of the ultrasonic waves obtained through the transmission sequence of the second ultrasonic group illustrated in Figure 2b as an example, the sequence of the echo data of the ultrasonic waves obtained at each position will be described, and the echo of the first type of ultrasonic waves will be recorded. The data is S1, the echo data of the second type of ultrasound is S2, and the ultrasound group Z transmitted at any one time is [S1, S2]. FIG. 3 illustrates a sequence diagram of an ultrasound transmission sequence.

In Figure 3, the x-coordinate is the position of the scanning plane, and the y-coordinate is the ensemble size of the scanning pulses repeatedly emitted at the same position. For the specific implementation method of acquiring ultrasonic echo data, reference may be made to the prior art.

S103. Obtain multiple ultrasound images according to the acquired ultrasound echo data.

Specifically, if at least one of the amplitude and phase of the multiple groups of transmitted pulses is different, corresponding ultrasonic echo data with at least one of the amplitude and phase different can be obtained. Such ultrasonic echo data can be used to obtain a contrast ultrasound image, such as Shown in Figure 4. The echo data of the ultrasonic waves corresponding to the transmitted pulses with the same amplitude and phase in different groups can be used to obtain blood flow ultrasound images, as shown in FIG. 5. A frame of ultrasound image can be obtained based on the echo data of the ultrasound at all positions of the scanning plane.

Therefore, according to the ultrasound echo data obtained in this step, this embodiment can obtain at least two ultrasound images, the first ultrasound image is a contrast ultrasound image, and the second ultrasound image is a blood flow ultrasound image. Specific ultrasound imaging methods may include:

A1. The imaging method of the contrast ultrasound image is: generating the echo data of the first type of ultrasound at each location and the echo data of the second type of ultrasound at each location.

In this step, a contrast signal can be generated at each target position according to the above method, and a contrast ultrasound image can be generated according to the contrast signal at all positions. Among them, the specific implementation of the contrast image signal processing method and the specific algorithm for generating the contrast ultrasound image can refer to the prior art.

A2. The imaging method of the blood flow ultrasound image is to obtain the blood flow ultrasound image according to the echo data of the first type of ultrasound at each location or the echo data of the second type of ultrasound at each location.

In this embodiment, the blood flow signal can be obtained at each target position according to the above method, and the blood flow ultrasound image can be generated according to the blood flow signal at all positions. Among them, the specific implementation of the blood flow signal processing method and the specific algorithm for generating the blood flow ultrasound image You can refer to the existing blood flow signal processing algorithm technology, which will not be repeated here.

It should be noted that, after the above-mentioned blood flow ultrasound image and contrast ultrasound image are obtained in one scan in the embodiment of the present application, the two ultrasound images can be further displayed at the same time to achieve the purpose of dual real-time imaging of the blood flow ultrasound image and the contrast ultrasound image. It should be noted that the purpose of dual real-time imaging is to display both blood flow ultrasound images and contrast ultrasound images. Simultaneously in this embodiment means that after one scan, the user (for example, the doctor) can see both the contrast ultrasound image and the blood flow ultrasound image, and the doctor can choose to display the blood flow ultrasound image at the same time or at different times. And contrast ultrasound images.

Further, according to the echo data for generating the blood flow ultrasound image, at least one of an energy Doppler ultrasound image and a blood flow variance ultrasound image can also be obtained.

Further, according to the ultrasonic echo data obtained in step S102, this embodiment can also obtain a third type of ultrasound image, that is, a tissue gray-scale ultrasound image. The specific implementation method is:

A3. Obtain a tissue gray-scale ultrasound image based on the echo data of the first type of ultrasound at each location, or the echo data of the second type of ultrasound at each location. The specific implementation of generating the tissue gray-scale ultrasound image can refer to the prior art, and its parameter settings are independent of the conventional gray-scale ultrasound imaging, so as to ensure that the optimal image can be debugged.

Further, when the ultrasonic waves emitted from different positions on the scanning plane are emitted in plane waves, or in the form of focused waves and the number of volume data packets is one, that is, the focused waves are emitted at one time to scan the entire area to be imaged. In this embodiment, a fourth type of ultrasound image, that is, a spectral Doppler ultrasound image, can also be obtained according to the acquired echo data of the ultrasound. The specific implementation method is:

A4. Generate a spectral Doppler ultrasound image of the target location based on the echo data of the ultrasound at the target location.

Among them, the target position is any position on the scanning plane. It should be noted that when there is one volume data packet, the number of repetitions of the data received at the same location can theoretically become very large. Generally speaking, the number of times 64 and above is suitable for spectral Doppler imaging. The spectral Doppler ultrasound image generation process in the embodiment needs to acquire more data length than blood flow imaging, so as to ensure that the effect of the spectral Doppler ultrasound image is better. The specific implementation method of generating the spectral Doppler ultrasound image can refer to the prior art, and the parameter setting and the spectral Doppler ultrasound image are independently set to ensure that the optimal image can be debugged.

It is understandable that after the embodiment of the present application executes the imaging algorithm once to obtain the above-mentioned blood flow ultrasound image, contrast ultrasound image, tissue gray-scale ultrasound image, and spectral Doppler ultrasound image, it supports simultaneous display of multiple ultrasound images. For example, after a scan, both blood flow ultrasound images, contrast ultrasound images and spectral Doppler ultrasound images can be displayed. This embodiment does not limit the time when each ultrasound image is displayed to be exactly the same.

It can be seen from the above technical solutions that the ultrasonic imaging method provided by the present application transmits an ultrasonic group at least twice at any position on the scanning plane. The transmitted ultrasound group includes a first type of ultrasound and a second type of ultrasound, and at least one of the amplitude and phase of the first type of ultrasound and the second type of ultrasound is different. Therefore, the echo data of the ultrasound group includes the echo data of the first type of ultrasound and the echo data of the second type of ultrasound, and the echo data of the first type of ultrasound and the echo data of the second type of ultrasound At least one of the amplitude and phase of is different. Therefore, by extracting and processing ultrasound echo data, blood flow ultrasound images and contrast ultrasound images can be obtained, which can achieve the purpose of dual real-time imaging of blood flow ultrasound images and contrast ultrasound images with one scan.

Furthermore, the echo data of the transmitted ultrasound group can also be used to obtain tissue gray-scale ultrasound images, so as to achieve tissue gray-scale ultrasound images, blood flow ultrasound images, energy Doppler ultrasound images, and blood flow variance with one scan. At least one imaging result of the ultrasound image and the contrast ultrasound image achieves the purpose of multiple real-time imaging. The method supports simultaneous display of multiple ultrasound images obtained, and meets the requirement of displaying multiple ultrasound images at the same time in practical applications, thereby supporting more diagnostic functions.

Further, when the plane wave or plane wave is used to transmit, or when the focused wave is transmitted and the number of volume data packets is one, the echo data of ultrasound can also be used to generate spectral Doppler ultrasound images. The calculation and display of spectral Doppler ultrasound images can be completed independently in one position.

Furthermore, the method of transmitting ultrasound groups at least twice in this application is set according to the imaging principle of blood flow ultrasound images, so the accuracy of the obtained blood flow ultrasound images is relatively high, and the number of transmission groups can be set according to the accuracy requirements. The greater the number of groups, the higher the accuracy of the blood flow ultrasound image, which leaves room for adjusting the accuracy of the image as needed.

It should be noted that in this embodiment, multiple ultrasound images can be obtained in one scan, that is, the "multi-type imaging" mode can be set in the ultrasound equipment, and the user can select this mode to obtain multiple ultrasound images in one scan. At the same time, keep the existing model. In different imaging modes, the parameters in the ultrasound image acquisition algorithm can be independent of each other and adjusted separately. For example, in a variety of imaging modes, in the blood flow ultrasound image imaging algorithm, the cut-off frequency of the filter is a parameter that needs to be set, and in the imaging algorithm in the blood flow ultrasound image mode, it is also necessary to set the cutoff frequency of the filter. The cut-off frequency of the filter in various imaging modes and the cut-off frequency of the filter in the existing blood flow ultrasound image mode can be set to different values, and can be adjusted separately. In other words, in different modes, although it is possible to use the same imaging algorithm, the parameters of the imaging algorithm are independent of each other to obtain a better imaging effect.

The ultrasound imaging method provided in the embodiments of the present application can be applied in a scenario where a contrast image needs to be generated for medical diagnosis.

Using the ultrasound imaging method provided by the embodiments of the present application, the imaging mode of blood flow ultrasound image + contrast ultrasound image can be realized through one scan, and the blood flow ultrasound image and the contrast ultrasound image can be displayed at the same time.

In addition, the ultrasound imaging method provided by the embodiments of the present application can also realize the spectral Doppler ultrasound image imaging mode through one scan, so that a more accurate blood flow velocity can be obtained by quantitative analysis.

In summary, the present application can realize real-time display of the direction of contrast agent perfusion and blood flow velocity during the imaging process, perform a more quantitative analysis of the lesion, and show that the blood perfusion form of the lesion is more helpful for the diagnosis of the lesion.

Furthermore, the present application can be used not only for two-dimensional (2D) contrast imaging, but also for three-dimensional (3D)/(4D) four-dimensional contrast imaging. The optional application scenarios of the ultrasound imaging method provided in this application in 3D/4D contrast imaging are tumor perfusion of the abdominal probe and hysterosalpingography of the intracavitary probe. In this application scenario, it is only necessary to focus on providing the signal of the contrast agent for blood flow ultrasound imaging and contrast ultrasound imaging.

This embodiment introduces the imaging method in this application scenario, as follows:

S1. After the user points the probe of the ultrasound device at the area to be imaged and triggers the multi-type imaging mode, the ultrasound group is transmitted at least twice at the target position on the scanning plane.

Wherein, each ultrasound group includes one first type of ultrasound and one second type of ultrasound, and at least one of the amplitude and phase of the first type of ultrasound and the second type of ultrasound is different (refer to Figure 2b).

It should be noted that in order to increase the frame rate of the contrast 4D system, plane wave transmission is used to transmit ultrasonic waves, or a higher number of imaging beams (the number of receiving lines obtained in one transmission) is used when focusing transmission, such as 32 beams, 64 beams And so on, which can reduce the number of shots and get better time resolution.

S2. Obtain echo data of the ultrasound group at all positions on the scanning plane of any slice.

S3. Perform signal processing on the echo data of the ultrasound group through the 3D/4D technology and the ultrasound imaging method provided in the embodiments of the present application to obtain the blood flow ultrasound image and the contrast ultrasound image in the 3D/4D mode.

As a result, real-time blood flow images can be used to identify the flow direction of the fallopian tube contrast agent in hysterosalpingography in 3D/4D contrast, which can assist in diagnosing the patency of the fallopian tube.

To sum up, in hysterosalpingography, the contrast ultrasound image and the blood flow ultrasound image can be directly displayed at the same time through one scan, so as to realize the display of the contrast agent perfusion and flow direction in the contrast ultrasound image to assist the diagnosis of the uterus and fallopian tubes. . At the same time, in the abdominal volume probe angiography, the spatial perfusion direction of blood flow can be better presented, and the diagnosis of lesions can be better assisted.

It should be noted that the contrast 3D/4D function is not limited to a motor-driven volume probe or an actual matrix 2D probe.
