Detailed ways

The embodiments of the present invention will be clearly and completely described in detail with reference to the accompanying drawings. An embodiment. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

At present, in order to obtain the normal or diseased condition of the living tissue through the echo intensity, the process of the echo intensity is: handing the sonogram showing the echo intensity to the professional, and then the professional observes the gray level of the sonogram through the naked eye, and The echo intensity is judged in combination with its own experience, and the echo intensity is determined as one of six levels of no echo, very low echo, low echo, equal echo, high echo, and strong echo. This There are technical problems with inaccurate determination of echo intensity. Based on this, the echo processing method, device and electronic device provided by the embodiments of the present invention can alleviate the technical problem that the echo intensity is not accurately determined by the conventional processing method for relieving the echo intensity of the ultrasonic wave after the human body tissue.

Embodiment 1

A method for processing echo strength according to an embodiment of the present invention, as shown in FIG. 1, includes:

Step S102, acquiring a first sonogram, wherein the first sonogram is a sonogram of the echo intensity of the preset portion of the ultrasonic wave on the target object, and the preset portion is a portion of the target object whose echo intensity is known.

Step S104, acquiring a second sonogram, which is a sonogram of the echo intensity of the ultrasonic wave at the part to be tested.

Step S106, calculating a ratio between the gray value of the first sonogram and the gray value of the second sonogram to determine the echo intensity of the portion to be tested according to the ratio.

It should be noted:

(1) The sonogram may be not only a picture presented in paper form but also an electronic image, which is not specifically limited herein. The size of the first image is determined by the size of the preset portion. The size of the second image is determined by the size of the portion to be tested. The size of the image is at least the size of the image acquired by the probe at the same time. The size of the image acquired by the probe at the same time depends on the size of the cross-section of the echo received by the probe. In general, the image acquired by the probe at the same time is an image including a plurality of pixels.

(2) The echo intensity of a part refers to the echo intensity of the echo obtained by the ultrasonic wave at this part.

(3) The first sound image is a sonogram of the echo intensity of the preset portion of the ultrasonic wave on the target object, and the second sound image is a sonogram of the echo intensity of the ultrasonic wave at the portion to be tested, here, the second sound image The ultrasonic waves corresponding to the corresponding ultrasonic waves and the first ultrasonic image are ultrasonic waves of the same energy.

Specifically, the energy amount of the echo has a one-to-one correspondence with the gray scale on the sound image, and thus, the ratio of the gray value of the first sound image to the gray value of the second sound image is a preset. The ratio of the echo intensity of the part to the echo intensity of the part to be tested, and if the echo intensity of the preset part is known, the gray value of the first sound image and the gray value of the second sound image may be The ratio is used to determine the echo intensity of the part to be tested.

It should be emphasized that the processing method of the echo intensity is to determine the degree of lesion of the part to be tested after the echo intensity of the part to be tested is processed. Therefore, the echo intensity here is not limited to the magnitude of the echo energy, and may also refer to The magnitude of the extent of the lesion in the organism characterized by the echo.

Wherein, in the case where the echo intensity refers to the magnitude of the echo energy, the preset portion is a portion of the target object whose echo energy is known, and the final determined echo intensity of the portion to be tested is the echo energy value of the portion to be tested. Since the echo intensity is closely related to the degree of pathological changes of the living tissue, the degree of lesion of the site to be tested can be obtained by knowing the value of the echo energy of the site to be tested.

In addition, in the case where the echo intensity refers to the degree of lesion of the organism characterized by the echo, the preset portion is the portion of the target object whose degree of the lesion is known, and the final determined echo intensity of the portion to be tested is the lesion of the portion to be tested. degree. In this embodiment, a portion of the target lesion with a known degree of lesion is directly selected, and then the degree of lesion of the portion to be tested can be obtained by the method of processing the echo intensity, the steps are simple, and the ratio is clearly determined. The extent of the lesion at the site to be tested.

In the embodiment of the present invention, the preset portion is used as the reference portion, and the echo intensity of the portion to be tested is determined according to the ratio between the gray value of the first sound image image and the gray value of the second sound image image.

First, the echo intensity is determined by observing the sonogram with the naked eye. In the embodiment of the present invention, the echo of the first image image and the gray value of the second image are calculated to determine the echo of the portion to be tested. Intensity, avoiding human error; and, this is a method of quantifying the echo intensity, and finally determining the echo intensity of the part to be tested by a numerical value, compared to the determination of the echo intensity in a certain range. The method is more precise and more helpful for today's computers to perform manual assisted diagnosis through a specific value.

In addition, although the echo energy is still affected by many factors in the process of receiving the echo by the probe in the embodiment of the present invention, the detection conditions such as the probe frequency, the probe angle and the probe gain do not accurately reflect the gray scale in the sound image. The energy of echoes after ultrasound through human tissue. However, in the case where the echo measurement of the preset portion and the echo measurement of the portion to be tested adopt the same probe frequency, probe angle, and probe gain, the echo intensity of the preset portion and the echo intensity of the portion to be tested are the same. Influence, finally, the influence of factors such as probe frequency, probe angle and probe gain is reduced by calculating the ratio of the first sonogram gray value to the second sonogram gray value.

In summary, the embodiment of the present invention alleviates the technical problem of inaccurate determination of echo intensity in the conventional processing method of echogenicity of ultrasonic waves after human tissue.

In an optional implementation manner of the embodiment of the present invention, as shown in FIG. 2, acquiring the first audio image image includes:

Step S201, selecting a preset part from a part of the target object adjacent to the part to be tested.

Specifically, the preset portion is selected from the portion adjacent to the portion to be tested on the target object, and the tissue having no lesion state may be selected from the portion adjacent to the portion to be tested.

Step S202, transmitting ultrasonic waves to the preset portion, and receiving echoes of the ultrasonic waves at the preset portion.

Specifically, the signal gain of the probe is adjusted according to the echo energy of the preset part and the echo energy of the part to be tested, the position of the probe is adjusted according to the echo propagation path, and then the signal gain of the probe and the position of the probe are adjusted, and then the probe is passed. The echo of the ultrasonic wave at the preset portion is received.

Step S203, generating a first sonogram according to the intensity of the echo of the ultrasonic wave at the preset portion, wherein the gray value of the first sonogram is configured to represent the magnitude of the echo intensity.

It should be noted that the embodiment of the present invention provides a specific implementation method for acquiring the first audio image. The same principle can be used to obtain the second image.

In the embodiment of the present invention, the preset part is selected from the part adjacent to the part to be tested on the target object, and the attributes of the part to be tested and the preset part are similar, then the gray value and the second sound of the first sound image are The ratio between the grayscale values of the image can be used more completely to reflect the difference in lesions between the site to be tested and the preset site.

For example, if the site to be inspected is a piece of skin on the arm of the person to be examined, a skin with no disease state can be found near the skin of the person to be tested. Wherein, the closer the ratio between the gray value of the first sonogram and the gray value of the second sonogram is to 1, the more the skin to be detected is closer to the disease-free state.

In another optional implementation manner of the embodiment of the present invention, calculating a ratio between a gray value of the first sound image image and a gray value of the second sound image image includes:

Calculating a gray value of the first sound image image according to the first sound image image;

Calculating a gray value of the second sound image image according to the second sound image image;

A ratio between a gray value of the first sound image and a gray value of the second sound image is calculated.

Specifically, calculating the gray value of the sound image according to the sonogram is to first calculate the gray value of the pixel in the sound image, and then calculate the gray value of the sound image by the gray value of the pixel.

Among them, the calculation of the gray value of the pixel is as follows:

Gray=R*0.299+G*0.587+B*0.114.

Where Gray is the gray value, R is the red brightness in the pixel, G is the green brightness in the pixel, and B is the blue brightness in the pixel. The range of R, G, B, and Gray is It is 0-255.

The gray value of the sound image is calculated by the gray value of the pixel, and can be combined with the normal distribution algorithm.

Specifically, the sonogram of the echo intensity of a living tissue includes a plurality of pixel points, each image The prime point has a gray value. When the lesion of the living tissue is fixed, the distribution of the gray values of all the pixels in the sonogram satisfies the normal distribution.

Figure 3 is a gray value distribution diagram of the echogenic intensity of a living tissue, and the horizontal axis represents the gray value, where μ represents the grayscale average of the sonogram, and σ represents the sonogram of the sonogram. The gray-scale variance, the horizontal axis label -nσ indicates that the gray value is μ-nσ (n=1, 2, 3); and the vertical axis indicates the ratio of the corresponding pixel points of the respective gray values to the total pixel points of the sound image. It can be seen from Fig. 3 that the smaller the difference between the gray level and the average value of the gray level of the sonogram, the more the corresponding pixel points occupy, especially the gray level average of the sound image. The pixel corresponding to the gray value whose difference is greater than the threshold has the possibility of an acquisition error. Therefore, when calculating the gray value of the sound image, the pixel with the acquisition error is removed to facilitate the grayscale of the sound image. Accurate calculation of values.

Based on the above description, the calculation method of the gradation value of the first sonogram and the calculation method of the second sonogram are described in detail below.

(1) calculating the gray value of the first sonogram according to the first sonogram, and the specific steps include:

Selecting a plurality of first target pixel points from the first sound image image, wherein a difference between a gray value of the first target pixel point and a gray average value of the first sound image image is smaller than a first preset value pixel.

It should be noted that the difference between the gray value of the first target pixel and the gray average of the first image is the gray value of the first target pixel minus the gray of the first image. The absolute value of the difference obtained by the average.

A gray average value of the plurality of first target pixel points is calculated, and a gray average value of the plurality of first target pixel points is determined as a gray value of the first sound image map.

(2) calculating the gray value of the second sound image image according to the second sound image image, and the specific steps include:

Selecting a plurality of second target pixel points from the second sound image image, wherein a difference between a gray value of the second target pixel point and a gray average value of the second sound image image is smaller than a second preset value pixel.

It should be noted that the difference between the gray value of the second target pixel and the gray average of the second image is the gray value of the second target pixel minus the gray level of the second image. The absolute value of the difference obtained by the average.

A gray average value of the plurality of second target pixel points is calculated, and a gray average value of the plurality of second target pixel points is determined as a gray value of the second sound image map.

Specifically, in the gray value distribution of the echo image of the echogenicity of the living tissue shown in FIG. 3, the first preset value may be set to 3σ, and the second preset value may also be set to 3σ.
