Hereinafter, first, an ultrasound imaging system according to an embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 shows a schematic structural block diagram of an ultrasound imaging system 100 according to an embodiment of the present invention.

As shown in FIG. 1, the ultrasound imaging system 100 includes an ultrasound probe 110, a transmitting circuit 112, a receiving circuit 114, a beam combining circuit 116, a processor 118, a display 120, a transmitting/receiving selection switch 122 and a memory 124. Wherein, the transmitting circuit 112 and the receiving circuit 114 can be connected to the ultrasonic probe 110 through the transmitting/receiving selection switch 122.

The ultrasound probe 110 generally includes an array of multiple array elements. Each time an ultrasonic wave is transmitted, all or some of the array elements of the ultrasonic probe 110 participate in the transmission of the ultrasonic wave. At this time, each of the array elements or parts of the array elements participating in the ultrasonic emission is excited by the emission pulse and emits ultrasonic waves respectively. The ultrasonic waves emitted by these array elements are superimposed during the propagation process to form the The synthetic ultrasonic beam of the target object, for example, the synthetic ultrasonic beam may be an ultrasonic wave emitted to the lungs of the target object (for example, a human body).

During the ultrasound imaging process, the transmitting circuit 112 transmits delayed-focused transmission pulses with a certain amplitude and polarity to the ultrasound probe 110 through the transmission/reception selection switch 122. The ultrasonic probe 110 is excited by the transmitted pulse to transmit ultrasonic waves to the scanning target object, and after a certain delay, it receives the ultrasonic echo with the information of the scanning target reflected and/or scattered from the target area, and regenerates the ultrasonic echo. Converted into electrical signals.

The transmitting/receiving selection switch 122 may also be called a transmitting/receiving controller, which may include a transmitting controller and a receiving controller. The transmitting controller is used to excite the ultrasonic probe 110 to transmit ultrasonic waves to a target object (such as a human body) via the transmitting circuit 112; The receiving controller is used to receive the ultrasonic echo returned from the target object via the receiving circuit 114 through the ultrasonic probe 110.

The display 120 can display the ultrasound image and the scoring result obtained by the processor 118. In addition, the display 120 can also provide the user with a graphical interface for human-computer interaction while displaying the ultrasound image. One or more controlled objects are set on the graphical interface, and the user can use the human-computer interaction device to input operation instructions to control these. Controlled object, so as to perform the corresponding control operation. For example, an icon is displayed on a graphical interface, and the icon can be operated using a human-computer interaction device to perform a specific function, such as the function of selecting a lung ultrasonography chart for comparison.

Optionally, the ultrasound imaging system 100 may also include other human-computer interaction devices other than the display 120, which are connected to the processor 118. For example, the processor 118 may be connected to the human-computer interaction device through an external input/output port, and the external input The output port can be a wireless communication module, a wired communication module, or a combination of the two. The external input/output ports can also be implemented based on USB, bus protocols such as CAN, and/or wired network protocols.

The memory 124 may be used to store instructions executed by the processor 118, used to store received ultrasound echo signals, used to store ultrasound images, and so on.

It should be understood that the components included in the ultrasound imaging system 100 shown in FIG. 1 are only schematic, and may include more or fewer components. The present invention is not limited to this.

Hereinafter, an ultrasound image analysis method according to an embodiment of the present invention will be described with reference to FIG. 2. FIG. 2 is a schematic flowchart of an ultrasound image analysis method 200 according to an embodiment of the present invention.

As shown in FIG. 2, the method 200 includes the following steps:

In step S210, an ultrasound image of the lung is acquired.

As an implementation manner, step S210 may include: reading a pre-stored ultrasound image of the lung from a storage medium. Then, the process of analyzing the acquired lung ultrasound image can be performed at any time after the lung ultrasound image is acquired. The stored ultrasound image of the lung can be read from the storage medium of the machine (for example, the memory 124), or the stored ultrasound image of the lung can be read from the storage medium of other devices via a wired or wireless network.

As another implementation manner, step S210 may include: acquiring the lung ultrasound image in real time.

Wherein, the step of acquiring an ultrasound image of the lung in real time may include: firstly, transmitting an ultrasound wave to the lung of the target object, and receiving an ultrasound echo based on the ultrasound to obtain an ultrasound echo signal; then, according to the ultrasound echo signal Obtain an ultrasound image of the lung of the target object. Exemplarily, the target object may refer to a human body to be detected or a part of the human body to be detected.

Specifically, in conjunction with FIG. 1, the transmission/reception selection switch 122 may be used to excite the ultrasonic probe 110 to transmit ultrasonic waves to the lungs of a target object (such as a human body) via the transmitter circuit 112, and receive the ultrasonic waves from the target object via the receiver circuit 114 through the ultrasonic probe 110. The ultrasound echo returned from the lungs is converted into an ultrasound echo signal. After that, the beam synthesis module 116 may perform beam synthesis processing, and then send the beam synthesized ultrasound echo signal to the processor 118 for related processing, so as to obtain an ultrasound image of the lung. In addition, the lung ultrasound image in the embodiment of the present invention may be obtained after performing a series of signal processing on the ultrasound echo signal, for example, including: analog-to-digital conversion, beam synthesis, IQ (in-phase quadrature, in-phase quadrature) solution. Tuning, logarithmic compression, grayscale conversion, etc.

In one embodiment, for each lung area of the lung, one or more frames of lung ultrasound images are respectively collected and stored in the memory 124. Among them, the left lung and the right lung can be divided into at least two lung regions, for example, the left lung and the right lung can be divided into 3, 4, or 6 lung regions respectively, etc., during the imaging process Acquire one or more frames of lung ultrasound images for each lung area.

In step S220, the ultrasound signs of each lung area in the lung ultrasound image are identified.

Among them, ultrasound signs refer to specific characteristics of the lungs. For example, the ultrasound signs of the lungs can include: bat sign, lung slip sign, beach sign, stratospheric sign, comet tail sign, lung spot sign, and Sexual tissue signs, liquid dark areas and so on. In this embodiment, some of the ultrasound signs can be identified for scoring, such as B-line, lung consolidation, and pleural effusion.

Among them, the B-line (also known as the "comet tail sign") is a discrete vertical reverberation artifact that extends from the pleural line to the bottom of the screen, without loss, and moving synchronously with the lungs. A large number of B-line acoustic shadows in ultrasound images are signs of pulmonary interstitial syndrome, and the number increases with the decrease of air content and the increase of lung tissue density. Therefore, B-line can be used to diagnose pulmonary edema and determine the degree of lung ventilation. In addition, in normal lung tissue, 0-2 isolated B lines can sometimes be seen in the same field of view. Specifically, because the normal lung tissue is full of gas and the sound waves are completely scattered, only the pleural line and the A-line can be seen under ultrasound, that is, several hyperechoic lines parallel to the pleural line and repeated. When lung parenchymal diseases (such as pulmonary edema, pneumonia, or acute lung injury) cause increased hydrostatic pressure or increased capillary permeability to widen the lobular septum, due to the decreased air content, some exudate, leaked fluid, collagen and blood As the lung density increases, the echo loss effect between the lung and surrounding tissues is also reduced. Ultrasound can reflect the image of the deeper area to a certain extent and produce some vertical mixed echoes, which is the above-mentioned B-line. According to the width of the B-line area, it can be divided into a single B-line and a diffuse B-line.

When the air content of the lungs is further reduced and the lung tissues become substantial, the sound image can be regarded as a solid tissue similar to the echoes of the liver and spleen. Pulmonary materialization is a progressive result, which can be caused by pulmonary embolism, cancer metastasis in the lung, compressed or obstructive atelectasis, and lung contusion. Signs of marginal tissue materialization, the presence of air and fluid, or vascular fusion also further indicate lung materialization.

When there is pleural effusion, the pleural line is separated from the lung surface, and the sound shadow of the upper and lower ribs forms a quadrilateral shape. The quadrilateral sign can be used as a characteristic sign of various pleural effusions. In addition, the sine wave sign is also a sign of pleural effusion, which means that the surface line of the lung displayed during M-mode ultrasound scanning moves toward the pleural line with the pulsation of breathing and presents a sine wave-like change.

In the embodiment of the present invention, automatic identification, manual identification, or a combination of automatic identification and manual identification can be used to identify the ultrasound signs in the lung ultrasound image.

For example, when automatic recognition is used, the trained neural network model can be used to automatically recognize the ultrasound signs in the lung ultrasound images. Specifically, the neural network model can be trained to enable the machine to recognize ultrasonic signs through a target detection algorithm. The target detection algorithm used may include Faster RCNN and the like.

Exemplarily, the step of training the neural network model includes: marking the ultrasound signs in the lung ultrasound image and inputting the neural network as a training sample for training until the model converges, thereby obtaining a trained neural network model. After that, the lung ultrasound image acquired in step S210 can be input into the neural network model, and the recognition result of the ultrasound signs therein can be output.

In addition, traditional image processing methods can also be used to identify ultrasound signs. For example, since the B line is a discrete vertical reverberation artifact that extends from the pleural line to the bottom of the screen, no loss occurs. Therefore, based on this feature, the B line can be identified by detecting the vertical linear feature in the direction of the sound beam. The recognition of linear features can be achieved through template matching and other methods.

In one embodiment, after the ultrasound signs are identified, they can also be quantitatively analyzed to obtain relevant parameters of the ultrasound signs. As an example, when the recognized ultrasound sign is a B-line, the main calculation parameters include the number of B-lines, the coverage percentage of the B-line, the interval between adjacent B-lines, and so on. The number of B lines is the total number of recognized B lines, the coverage percentage of B line is the percentage of the area occupied by the B line in the lung detection area, and the interval between adjacent B lines is the distance between the B lines at the position of the pleural line .

In the embodiment of the present invention, the ultrasonic signs can be automatically recognized by the above-mentioned method, the ultrasonic signs can also be manually recognized and marked by the user, or the ultrasonic signs can be recognized by a combination of automatic and manual methods. For example, automatic identification methods can be used to identify the relatively easy-to-identify B-line, and complex diseases such as lung consolidation and pleural effusion can be manually marked.

After the lung ultrasound images of each lung area are recognized, the most representative one or more frames of lung ultrasound images can be selected as the final result based on the recognition results. For example, the recognition result of one or more frames of lung ultrasound images with the largest number of B-lines, or the recognition result of one or more frames of lung ultrasound images with the largest percentage of B-lines can be selected. The specific selection criteria can be set by the user.

In step S230, the various lung regions are scored according to the ultrasound signs to generate a score result.

Wherein, the scoring result identifies the degree of damage of each lung area of the lung. As an example, the higher the score, the more severe the lung damage. In the embodiment of the present invention, various scoring standards commonly used in clinical practice can be used for scoring, such as the pulmonary superventilation scoring method, or new scoring standards can be used for scoring.

In one embodiment, each lung area can be scored according to the number of B lines, lung consolidation, and pleural effusion identified in step S220.

For example, when 0-2 isolated B lines are detected, it means that the lungs are normally ventilated, and it is scored as 0 points. When multiple B-lines with clear intervals are recognized, that is, more than 3 single B-lines are detected, it means that the lung tissue is at a moderate aeration, which is scored as 1 point. When a densely fused B-line is identified, that is, an aliased B-line appears, it indicates severe lung tissue degassing, which is scored as 2 points. When there is lung consolidation or lung consolidation with pleural effusion, it is scored as 3 points.

In order to facilitate quantitative analysis, the scoring format can be a number, such as 0-3. However, the scoring format can also be text, such as N, B1, B2, C, which correspond to different severity levels. In step S230, not only can the score of a single lung area be obtained based on a single lung ultrasound image, but also the scores of each lung area can be added to obtain the overall score of the lung.

Exemplarily, the scoring may be an automatic scoring, for example, the system automatically converts the ultrasound sign recognition result into a scoring result. Or, when training the neural network model, the neural network model directly outputs the scoring result. It is also possible for the user to manually score according to the ultrasound signs identified in step S220.

In one embodiment, after the score is generated, an operation interface may be provided to the user, so that the user can confirm or modify the score of each lung region through the operation interface. After the user confirms the score obtained in step S230, step S240 is continued. In another embodiment, after the ultrasonic signs are recognized in step S220, an operation interface may also be provided to the user, so that the user can confirm or delete the recognized ultrasonic signs through the operation interface. Of course, the above-mentioned operation interface is not necessary, and the subsequent steps can be performed directly without the user's operation.

In step S240, a lung ultrasound scoring chart is displayed on the display interface, the lung ultrasound scoring chart includes a lung graphic and an identifier displayed at each lung region of the lung graphic, and the identifier is used to characterize all of the corresponding lung regions. Describe the scoring results.

Among them, the user can quickly understand the scoring results of each lung area according to the marks displayed at each lung area in the lung graph, so as to visually present the patient's lung damage to the doctor, which is convenient for monitoring the patient's health status and helps Follow-up targeted treatment by doctors to patients. The lung graphic can be a structural diagram that reflects the shape of the lung. The structural diagram can be, for example, the two-dimensional schematic diagram shown in Figure 3a, Figure 3b and Figure 4, or a three-dimensional diagram; the structural diagram can be as shown in Figure 3a, Figure 3b. The line model diagram shown in FIG. 4 may also be a rendering diagram. The lung graphics can also be other indicators that have a structural relationship with the lungs in equal or approximate proportions, for example, it can be a rectangular indicator that is divided into two. The present invention does not limit the specific presentation mode of the lung graphics.

In one embodiment, step S240 includes: displaying a single-scored lung ultra-score (LUS) graph on the display interface. That is to say, only one lung ultra-score map is displayed on the display interface, and the lung ultra-score map includes only one lung graphic. Based on a single lung ultra-score map, it can visually display the damage of multiple lung areas, and it can also allow users to quickly overview the overall condition of the lungs, thereby judging which part of the lungs is more severely damaged. In some examples, the damage of a single lung area can also be displayed based on the lung ultra-score map. The scoring result of which lung area is displayed can be determined according to the user input, and the scoring result of which lung area is displayed can also be determined according to the preset order in the system. It can also be combined with the score of the lung area to determine which lung area or several lung areas will be displayed for damage. For example, the processor 118 controls the display according to the damage condition of one or more lung regions whose scoring result exceeds a preset scoring threshold.

In one embodiment, the processor 118 may also control the display to provide dynamic display effects of one or more lung regions. Combined with the schematic diagram of FIG. 3a, the processor 118 can control the display to display the damage of each lung area of the right lung in the order of 1R lung area, 2R lung area, 3R lung area, and 4R lung area. The processor 118 can control the display to display the damage of each lung area of the right lung according to the 1R lung area. , 1L lung area, 2R lung area, 2L lung area... alternately show the damage of each lung area of the right lung and left lung. It can also be combined with the score of the lung area to determine which lung area or several lung areas will be displayed for damage. For example, the processor 118 controls the display to sequentially display the injury status of one or more lung regions according to the level of the scoring result.

As an example, the logo may include graphics. The graphics may use one or more of different colors, brightness, texture, texture density, patterns, pattern density, filling area, or shape to characterize the score of the scoring result. For example, graphics of different colors can be displayed at the location of the corresponding lung area of the lung graphics according to the level of the score. According to the color of the graphics, the user can quickly obtain the score of the corresponding lung area.

In order to facilitate understanding, the embodiment of the present invention provides two visualization implementation forms of lung ultra-score maps, as shown in Fig. 3a, Fig. 3b and Fig. 4.

First, referring to Fig. 3a, in the first form of lung ultrasound scoring map, the marks used to characterize the scoring results are displayed at the positions of each lung area of the lung graph, and the lung ultrasound image can be displayed after clicking the mark. This form of lung ultrasonography scoring map is relatively simple and intuitive, and can quickly convey the information of the scoring result to the user. The dividing line of each lung area may be displayed, or the dividing line between lung areas may not be displayed as shown in Fig. 3a.

In an embodiment, the identifier may be a color block or color frame of different colors, and the color block or color frame of each color represents a score of the scoring result. The shape of the color block or color frame is not limited to a certain one, for example, it may be a circle, a square, a triangle, or the like. The identification of different lung regions can be the same or different. In FIG. 3a, the logo is exemplified as circular graphics with different textures, but it is understandable that in actual application, different textures can be replaced with different colors.

According to the value of the score, the color of the logo can have a certain change rule to facilitate users to understand and remember. For example, the color of the logo can change from dark to light, or from one color system to another as the score increases. Color system. As an example, green means 0 points, yellow means 1 point, orange means 2 points, and red means 3 points.

In one embodiment, the mark further includes the score (not shown) of the scoring result displayed in the color block or color box, so that the scoring result is represented in two forms of graphics and text. However, it should be noted that in other embodiments, the number of the corresponding lung area can also be displayed inside the graph, as shown in Figure 3a, where 1R, 2R, 3R, and 4R represent the right lung areas 1 to 4, 1L, 2L , 3L and 4L represent the left 1 to 4 lung regions, respectively.

As mentioned above, when the above-mentioned form of lung ultra-score map is adopted, the lung ultra-score map can also be used as a playback navigation interface, that is, when a selection instruction for a certain lung area identification of the lung ultra-score map is received, The lung ultrasound image corresponding to the lung area can be displayed on the display interface. Specifically, referring to Figure 6, if the user clicks on the 1R lung area logo on the lung superscore map on the left side of the display interface (you can select or highlight the logo at this time), the 1R lung area will be displayed on the right side of the display interface. Ultrasound image of the lung corresponding to the area, so that the diagnostic image can be reviewed in detail.

In one embodiment, each lung area may correspond to one or more frames of the lung ultrasound image. That is, each lung area can store one or more frames of lung ultrasound images in the memory 124 correspondingly. Continuing to refer to FIG. 6, when each lung area corresponds to storing multiple frames of lung ultrasound images, a list 601 of candidate ultrasound images may be displayed on the display interface (for example, on the side of the lung ultrasound image) for the user to select, and It is also possible to frame or highlight the currently displayed ultrasound image in the list 601.

In one embodiment, referring to FIG. 6 continuously, in order to display the changes of the injury condition of each lung area at each stage of the treatment process, a score chart 602 of multiple scoring results of the selected lung area may be displayed on the display interface. The scoring chart 602 may be a graph, a line chart, a histogram, a histogram, and other forms of charts, and the scoring chart 602 may also be a table that records the results of various scorings, which is not limited in the present invention.

As an example, when the scoring chart 602 adopts a graph or a broken line graph, each point on the curve or a broken line may be used to respectively represent the scoring results of multiple scores. In addition, the currently displayed scoring result of the lung ultrasound image may be highlighted in the scoring chart, so that the user can judge the position of the current scoring result in the chart.

Further, the scoring result on the scoring chart 602 may have a mapping relationship with the lung ultrasound image corresponding to the selected lung area. When a selection instruction for the scoring result on the scoring chart 602 is received, that is, when the user clicks a point or line on the chart that represents the scoring result, the lung corresponding to the scoring result can be displayed on the display interface. Ultrasound image, that is, replace the currently displayed lung ultrasound image with the lung ultrasound image corresponding to the selected scoring result, and synchronously switch the lung scoring chart to the lung scoring chart corresponding to the scoring result.

Further, text 603 may also be used on the display interface to show the scoring result or the ultrasound sign recognition result. The scoring result includes a score, and the ultrasound sign recognition result is, for example, the number of B-lines and B-line coverage in the lung ultrasound image.

Fig. 3b shows a lung ultrasonogram according to another embodiment of the present invention. The lung ultrasound scoring map displays markers used to characterize the scoring results at the positions of each lung area of the lung graph, and the lung ultrasound images can be displayed after clicking the markers. The dividing line of each lung area may be displayed as shown in Figure 3b, or the dividing line between lung areas may not be displayed.

The mark in Figure 3b is the overlay superimposed on each lung area. The covering part can characterize the score of the scoring result with different colors, brightness, texture, texture density, patterns, pattern density, and/or filling area. Figure 3b illustrates the use of different textures to characterize the score. The logo covering the entire lung area is the same as the logo shown in FIG. 3a. After receiving the user's selection, the logo itself can be highlighted/highlighted, and at the same time, the lung ultrasound image corresponding to the lung area can be called to display. In an example not shown, the scoring result of the corresponding lung area may be displayed on the covering part.

Fig. 4 shows a second form of lung ultrasound score chart according to another embodiment of the present invention. When this form of lung ultrasound scoring map is adopted, the lung ultrasound images of the corresponding lung regions are displayed at each lung region of the lung graph, and the marks that characterize the scoring result are displayed simultaneously with the lung ultrasound images. The lung ultrasound image displayed at each lung area may be the frame with the highest score in the lung area, or it may be a frame manually designated by the user. According to this form of lung ultrasound scoring map, users can not only view the scoring results of each lung area, but also quickly view the ultrasound images of each lung area at the same time.

As an example, when the logo is displayed synchronously with the lung ultrasound image, the logo can be displayed on the lung ultrasound image. For example, the logo can be a frame, corner marker or other graphics displayed on the lung ultrasound image. Alternatively, the logo can also be displayed side by side with the lung ultrasound image. For example, the logo can be a border displayed next to the lung ultrasound image, or an indicator bar displayed next to the lung ultrasound image. Alternatively, an ultrasound image of the lungs can be displayed on the logo.

As an example, the logo in this embodiment may have different colors, brightness, filling areas, patterns, shapes, or textures to represent the score of the scoring result. For example, referring to FIG. 4, a corner mark 402 with a different color (not shown) may be displayed as the mark in the lower right corner of the lung ultrasound image. The colors of the marks representing different scores can be the same as in the previous embodiment, that is, green can be used to represent 0 points, yellow to represent 1 point, orange to represent 2 points, and red to represent 3 points.

Continuing to refer to FIG. 4, in one embodiment, when the logo is displayed synchronously with the lung ultrasound image, the score value (Score) and the number of B lines can also be displayed on the lung ultrasound image or synchronously with the lung ultrasound image. One or more of (B lines) and B line coverage percentage (Percent). Further, the total score (LUS) of each lung area can also be displayed on the lung ultra-score map. According to the total score displayed on the lung ultra-score chart, the user can quickly learn the overall condition of the lungs. In addition, the number of the corresponding lung area can also be displayed on the lung ultrasound image. For example, the 1R, 2R, and 3R shown in the upper right corner of the lung ultrasound image indicate the first, second, and third lung areas of the right lung, 1L, 2L and 3L represent the first, second, and third lung regions of the left lung, respectively.

In one embodiment, when a selection instruction for a lung ultrasound image of a certain lung area of the lung ultrasound scoring map is received, the selected lung ultrasound image can also be enlarged and displayed on the display interface for the user to view in detail The selected ultrasound image of the lungs.

In one embodiment, referring to FIG. 5, the method 200 further includes: outputting an ultrasound report, the ultrasound report including the lung ultrasonogram. Among them, the first form of lung ultrasound scoring chart shown in Figure 3 is very concise and intuitive for the presentation of the diagnosis results, so it is very suitable to be included in the report as the assessment result chart. Of course, according to the needs of users, the ultrasound report can also use the second form of lung ultrasound score chart shown in Figure 4. The lung ultra-score map output to the ultrasound report can be consistent with the lung ultra-score map displayed on the display interface. For reasons such as report printing, it is also possible to make adaptive adjustments when outputting the lung ultrasound score map, adjust the logo on the lung ultrasound score map to a mode suitable for printing, remove the lung ultrasound images of each lung area and only display the logo. And/or only output signs that the scoring result exceeds the preset scoring threshold on the lung ultrasonographic scoring map, etc. For example, the lung ultrasound scoring map in Figure 3 is marked as a color block, and the color block can be directly converted into a color frame when outputting to an ultrasound report.

The above exemplarily describes the specific details of displaying a single lung ultrasound score map on the display interface. In another embodiment, referring to FIG. 7, step S240 may further include: simultaneously displaying multiple windows on the display interface, each window displaying the lung ultrasonography score scored once. For example, in Figure 7, four windows are displayed on the display interface, and a lung ultrasonogram scored once is displayed in each window.

When multiple scoring lung ultrasonography charts are displayed on the display interface at the same time, the user can view the scoring results of each stage of the treatment process at the same time, so as to visually compare and evaluate the treatment effect of each part. For example, as the treatment progresses, the identification of each lung area on multiple lung ultrasonographic maps changes from red to orange, or from orange to yellow or green, which visually shows the improvement of lung ventilation.

Wherein, the lung ultrasound scoring map displayed in each window of the multiple windows can be any of the above-mentioned lung ultrasound scoring maps, but preferably, the lung ultrasound scoring maps of the multiple windows adopt the same format to facilitate the process. Compared. Since the first form of lung ultrasound score map described in conjunction with FIG. 3 is relatively concise and intuitive, in one embodiment, when multiple lung ultrasound score maps are simultaneously displayed for comparison, for example, the first format described above can be used. Lung ultrasound score chart.

As an example, when multiple lung ultrasound scoring charts are displayed on the display interface at the same time, the acquisition time of the lung ultrasound scoring chart is displayed in each window, and the lung ultrasound scoring charts are arranged in the order of the acquisition time. Scoring chart for easy viewing by users.

In one embodiment, when multiple lung ultrasound scoring charts are displayed on the display interface at the same time, when an instruction to select a certain lung area in the lung ultrasound scoring chart in one of the windows is received, the other is automatically highlighted. The identification of the corresponding lung area in the lung ultra-score map of one or more windows. That is to say, if the user selects an icon in one window, for example, if the user selects the 1L lung area icon in the upper right window of the window in Figure 7, the lung ultrasound scores in the other three windows The logo of the 1L lung area in the figure is automatically highlighted or enlarged, so that the user can compare the scores of the 1L lung area at various time points.

In one embodiment, the method 200 further includes: highlighting a change in the scoring result of a certain lung area on the lung ultra-score map of a scoring time relative to the lung ultra-score map at a time before or after the scoring. Logo. That is to say, when in a scoring, the scoring result of a certain lung area changes relative to the scoring result at the time before or after the scoring, it will be displayed in the lung ultrasound scoring chart generated based on the scoring. Displays a sign indicating that the scoring result has changed to remind the user to focus on the lung area.

As an example, the indicator that characterizes the change in the scoring result may be a graphic or text, and the graphic or text may be a fixed graphic or text, that is, it only prompts that the scoring result has changed, and does not prompt whether the scoring result has increased or decreased. Or, different signs can also be used to indicate an increase or decrease in the scoring result respectively.

In one embodiment, the method 200 further includes: obtaining the difference between the scoring results of each lung area at two adjacent acquisition times; The difference is displayed as a graphical element on the graph. Wherein, the graphic element may have one or more of different colors, sizes, shapes, textures, patterns, filling areas, and pattern densities to represent the magnitude of the difference. The graphic element that characterizes the difference can be displayed in parallel with the mark that characterizes the scoring result, or overlapped with the mark that characterizes the scoring result.

For example, refer to Figure 7, where in the lung ultra-score map on April 5, 2018, the scoring results of the 4R lung area and the 4L lung area have changed relative to the scoring results of the lung ultra-score map on April 1, 2018 , The scoring results of the two lung regions are reduced by 1 point. Therefore, the same graphic elements (not shown) can be displayed at the corresponding lung regions to indicate that the scoring results have decreased by 1 point.

In one embodiment, when it is received that at least two of the lung ultrasound scoring maps are selected for comparative evaluation, at least two of the lung ultrasound scoring maps and their corresponding lung ultrasound images are displayed in multiple windows of the display interface , To allow users to compare and analyze the results of two ultrasound diagnosis with the combination of lung ultra-score map and specific lung ultrasound images.

It should be noted that the user can select two lung ultrasound score maps for comparative evaluation on the display interface that displays multiple lung ultrasound score maps, or select two lungs on the two display interfaces that display a single lung ultrasound score map. Super score chart for comparative evaluation.

Further, when an instruction to select at least two of the lung ultrasound score maps for comparative evaluation is received, at least two sets of windows are displayed on the display interface at the same time, and one of the selected lung ultrasound scores is displayed in each set of windows Figure and its corresponding lung ultrasound image. Among them, the user can click on any position of the lung ultrasound scoring chart to select the corresponding lung ultrasound scoring chart for comparative evaluation, or the user can also select a specific mark of the lung ultrasound scoring chart to directly select the lung ultrasound image of the corresponding lung area for comparison and evaluation. Conduct comparative evaluation.

For example, referring to Figures 7 and 8, when the lung ultrasound scores scored twice on April 1, 2018 and March 30, 2018 are selected in the display interface shown in Figure 7 for comparative evaluation, the display interface Two sets of windows are shown on the upper row. The first set of windows in the upper row shows the lung ultrasound score chart on April 1, 2018 and the lung ultrasound image for comparative evaluation. The lungs in the 1R lung area are selected here. Ultrasound images of the lungs; the second set of windows located in the lower row shows the lung ultrasound scoring map on March 30, 2018 and the lung ultrasound images at the same lung area, that is, the lung ultrasound images of the 1R lung area. As an example, the identifier of the currently displayed lung ultrasound image can also be highlighted in the lung ultrasound scoring map, such as highlighting or zooming in.

During comparative evaluation, when a lung ultrasound image of a certain lung area is selected for display in a lung ultrasound scoring chart, the lungs at the corresponding lung area of the other one or more lung ultrasound scoring charts for comparison evaluation are automatically displayed Ultrasound image. For example, continuing to refer to Figure 8, suppose that the user changes the selected lung area from 1R lung area to 1L lung area in the lung ultrasonographic scoring chart on April 1, 2018. The first set of windows will display the lung area on April 1, 2018. For the lung ultrasound image of the 1L lung area, the processor 118 can further control to automatically change the selected lung area from the 1R lung area to the 1L lung area on the lung ultrasound scoring map on March 30, 2018. At this time, the second set of windows This will show the lung ultrasound image of the 1L lung area on March 30, 2018. Through the above-mentioned linkage selection of the lung area, the operation friendliness of the comparative evaluation can be further improved, and the user's repeated useless workload can be reduced.

The above-mentioned FIG. 8 displays the comparative evaluation in two sets of windows. In another example, the processor 118 may display the corresponding set of windows according to the number of acquired lung ultrasonography images. For example, compared to the situation in which four lung ultrasonography scoring maps are provided in FIG. 7, when an instruction to compare and evaluate the lung ultrasonography scoring maps is received, the display 120 can be controlled to display four sets of windows on the display interface, and each set of windows is displayed separately A lung ultrasound scoring map and its corresponding lung ultrasound image.

In summary, the ultrasound image analysis method 200 of the embodiment of the present invention scores each lung area, and generates and displays a lung ultra-score map based on the score result, so that the lung imaging results can be visually displayed and compared, so that Lung ultrasound examination can better meet clinical needs.

Hereinafter, an ultrasound image analysis method 900 according to another embodiment of the present application will be described with reference to FIG. 9. As shown in FIG. 9, the ultrasound image analysis method 900 may include the following steps:

In step S910, an ultrasound image of one or more regions of the object to be measured is acquired.

Among them, the measured object can be a human body, a fetus, or an animal. Alternatively, the object to be measured may be a part of the human body to be detected, such as the chest and abdomen of the human body. When the measured object is a human body, one or more regions of the measured object include, for example, tissues and organs such as the heart, lungs, liver and gallbladder, spleen and stomach. Specifically, the ultrasonic imaging system shown in FIG. 1 may be used to transmit ultrasonic waves to the area to be measured of the object to be measured, and an ultrasonic image of the area can be obtained according to the ultrasonic echo returned from the area to be measured.

In step S920, the ultrasound signs in the ultrasound images of the one or more regions are identified.

Among them, ultrasound images in different regions have different ultrasound signs. For example, the ultrasound signs in the lung ultrasound image are such as B-line, lung consolidation, and pleural effusion; the ultrasound signs of the intestine include, for example, intestinal dilatation, gas intestinal cavity, cockscomb sign, piano key sign, etc. or Characterize the pseudo-kidney sign, target ring sign, etc. of intestinal tumors; the ultrasound signs of the liver and gallbladder parts, such as the target sign and anti-target sign of liver nodules, and the floating vessel sign of liver lymphoma and many more.

For ultrasound images in different areas, automatic identification, manual identification, or a combination of automatic identification and manual identification can be used to identify the ultrasound signs. For example, for different regions, neural network models can be trained separately to automatically identify ultrasound signs in them. The embodiment of the present invention does not limit the recognition method of ultrasound signs.

In step S930, the ultrasound images of the one or more regions are scored according to the ultrasound signs to generate a score result.

Wherein, the scoring result can characterize the degree of damage in each area of the tested object, for example, the higher the score, the more severe the damage degree. In the embodiment of the present invention, automatic, manual, or a combination of automatic and manual methods can be used to score each area based on ultrasound signs.

In step S940, an ultrasound scoring chart is displayed on the display interface, the ultrasound scoring chart includes a graphic of the object to be measured and an identifier displayed at one or more regions of the graphic of the object to be tested, and the identifier is used to characterize The scoring result of the corresponding area. The graph of the measured object can be a structural diagram that reflects the shape of the measured object, or it can be other indicator graphs that have a corresponding proportional relationship with the measured object. For example, when the object to be measured is the lungs of a human body, the graphic of the object to be measured may be a graphic of lungs. For example, when the measured object is multiple tissues/organs of the human body, the graph of the measured object may be a human body model diagram, and optionally the structure diagram of the tissue/organ corresponding to one or more regions is displayed on the human body model diagram . For example, when the object to be measured is the heart, the image of the object to be measured may be a four-quadrant diagram, corresponding to the four chambers of the heart.

Wherein, the identifier may include a graphic, and the graphic uses one or more of different colors, brightness, texture, texture density, patterns, pattern density, filling area, or shape to characterize the score of the scoring result.

In one embodiment, a single-scored ultrasound scoring chart is displayed on the display interface, and the ultrasound scoring chart can have two forms: the first form of ultrasound scoring chart is similar to the lung ultrasound scoring chart shown in FIG. 3, That is, one or more areas of the graph of the measured object are displayed with signs that characterize the scoring results. At this time, the ultrasound scoring chart can be used as a playback navigation interface, that is, when the signs of each area are clicked, the ultrasound image of the corresponding area is displayed on the display interface.

The second form of ultrasound scoring chart is similar to the lung ultrasound scoring chart shown in FIG. 4, that is, the ultrasound scoring chart and the ultrasound image are simultaneously displayed on the graph of the measured object. Wherein, the figure of the measured object depends on the type of the measured object. For example, when the measured object is a human body, the figure of the measured object is a human shape or an approximate human shape. For example, when the measured object is a specific tissue or organ, the image of the measured object is an image of the corresponding tissue or organ. For example, when the measured object is the liver, the displayed image is the liver image.

In another embodiment, multiple windows are displayed on the display interface at the same time, and each window displays a once-scored ultrasound scoring chart. When multiple scoring ultrasound scoring charts are displayed on the display interface at the same time, the user can understand the patient's scoring results at different stages at the same time, so as to visually compare and evaluate the changes in various parts.

Wherein, the ultrasound scoring chart displayed in each window of the multiple windows may be any of the above-mentioned ultrasound scoring charts, but preferably, the ultrasound scoring charts of the multiple windows are in the same form to facilitate comparison. Since the above-mentioned first form of ultrasound scoring chart is relatively simple and intuitive, in one embodiment, when multiple ultrasound scoring charts are displayed for comparison at the same time, for example, the above-mentioned first form of ultrasound scoring chart can be used.

As an example, when multiple ultrasound scoring charts are displayed on the display interface at the same time, the acquisition time of the ultrasound scoring chart is displayed in each of the windows, and the ultrasound scoring charts are arranged in the order of the acquisition time, To facilitate users to view.

In one embodiment, when multiple ultrasound scoring charts are displayed on the display interface at the same time, when an instruction to select a certain area of the ultrasound scoring chart in one of the windows is received, the other one or more are automatically highlighted. The corresponding area of the ultrasound score map of each window is identified, so as to facilitate the user to compare the scores of the area at various time points.

In one embodiment, it is also possible to highlight on the ultrasound scoring chart of a single scoring an indication that the scoring result of a certain area of the ultrasound scoring chart at a time before or after the scoring has changed. That is to say, when in a scoring, the scoring result of a certain area has changed with respect to the scoring result at the time before or after the scoring, it will be displayed in the ultrasound scoring chart generated based on the scoring. The mark that the scoring result has changed to remind the user to focus on the area.

As an example, the indicator that characterizes the change in the scoring result may be a graphic or text, and the graphic or text may be a fixed graphic or text, that is, it only prompts that the scoring result has changed, and does not indicate whether the scoring result has increased or decreased. Or, different signs can also be used to indicate an increase or decrease in the scoring result respectively.

In one embodiment, the method 900 further includes: obtaining the difference between the scoring results of each area at two adjacent acquisition times; and placing the score on the ultrasound scoring chart in a window corresponding to the ultrasound scoring chart at a later time. The graphic element displays the difference. Wherein, the graphic element may have one or more of different colors, sizes, shapes, textures, patterns, filling areas, and pattern densities to represent the magnitude of the difference. The graphic element that characterizes the difference can be displayed in parallel with the mark that characterizes the scoring result, or overlapped with the mark that characterizes the scoring result.

In one embodiment, when it is received that at least two of the ultrasound score maps are selected for comparative evaluation, at least two of the ultrasound score maps and their corresponding ultrasound images are displayed in multiple windows on the display interface to allow the user to Combine the ultrasound score chart and specific ultrasound images to compare and analyze the results of the two ultrasound diagnosis.

It should be noted that the user can select two ultrasound score maps for comparative evaluation on the display interface that displays multiple ultrasound score maps, or select two ultrasound score maps on the two display interfaces that display a single ultrasound score map. Comparative assessment.

Further, when an instruction to select at least two of the ultrasound score maps for comparative evaluation is received, at least two sets of windows are displayed on the display interface at the same time, and each set of windows displays the selected one of the ultrasound score maps and Its corresponding ultrasound image. Among them, the user can click any position of the ultrasound scoring map to select the corresponding ultrasound scoring map for comparative evaluation, or the user can also select a specific mark of the ultrasound scoring map to directly select the ultrasound image of the corresponding area for comparative evaluation.

In another embodiment, when an ultrasound image of a certain area of one ultrasound score chart is selected for display, the ultrasound images at the corresponding area of the other one or more ultrasound score charts are automatically displayed.

In summary, the ultrasound image analysis method 900 of the embodiment of the present invention scores each area of the object to be tested, and generates an ultrasound score map based on the score result for display, so that the ultrasound diagnosis results can be visually displayed and compared, so that Ultrasound diagnosis can better meet clinical needs. The above-mentioned scheme of comparative evaluation of the results of multiple scores can make reasonable use of the historical examination data of the same patient, so that the doctor can fully understand the changes of the patient over a period of time.

Hereinafter, an ultrasound imaging method 1000 according to another embodiment of the present application will be described with reference to FIG. 10. The ultrasound imaging method can guide the current scan of the tested object based on the historical scoring situation of the tested object. As shown in FIG. 10, the ultrasound imaging method 1000 may include the following steps:

In step S1010, a historical ultrasound score map of the measured object is obtained, the historical ultrasound score map includes the measured object graph and the identifiers displayed in one or more regions of the measured object graph, and the identifiers are used to characterize the history. score. The historical ultrasound score chart can present the comprehensive score of the tested object in the past period of time, the historical score of the tested object in the last ultrasound imaging examination, and it can also display the number of tested objects in the past period of time. Ratings. Through the identification of one or more areas, the user can intuitively understand the historical situation of each area and guide the real-time scan to be performed based on the historical situation.

The logo can include graphics. The graphics may use one or more of different colors, brightness, texture, texture density, pattern, pattern density, filling area, or shape to represent the score of the score. For example, graphics of different colors can be displayed in each area on the graph of the object to be tested according to the level of score. According to the color of the graph, the user can quickly obtain the score of the corresponding area. The ultrasound scoring map can refer to the manner of FIG. 3 to display the identification of the score representing the score; the ultrasound scoring map can also refer to the manner of Figure 4 to synchronously display the ultrasound image corresponding to the region and the identification of the representative scoring score in each area. For example, when the measured object is a human body, one or more areas may be thyroid, liver and gallbladder, kidney, spleen, ureter, etc. The historical ultrasound scoring map can display the corresponding one or more historical scoring results in each area with color-distinguishable marks.

In step S1020, scan instructions for one or more regions are generated according to the historical scores. The scanning instruction can be embedded in the scanning workflow, requiring the user to perform real-time scanning according to the scanning instruction; it can also provide interface instructions on the interface to prompt the user for the current real-time scanning. In one embodiment, the scanning sequence of one or more regions can be generated according to the score of the historical score. For example, the higher the score, the more serious the damage in the area is. The method can prompt the user to scan each area in real time in the order of the score from high to low. In one embodiment, the processor will determine the relationship between the scores of each area and the preset score threshold in the system. If it exceeds the preset threshold, it is considered that the area belongs to the area that needs the user's current focus and can be displayed on the graph of the object under test. Highlight these areas to guide users to focus on scanning these areas. The preset threshold for each area can be the same or different. In one embodiment, the processor can analyze the changes in the historical scores of each region, and set one or more region scanning sequences according to how much the score has risen or the time it takes to rise, or increase the score beyond a preset value. The corresponding area where the difference threshold or the rising time is lower than the preset time threshold is highlighted as the area to be focused on.

In step S1030, according to the scanning instruction, ultrasonic waves are sent to one or more regions of the object to be tested for scanning, and ultrasonic echo signals are obtained. As above, when the scanning instruction provides the scanning sequence, the ultrasound can be sent to each area of the object to be scanned in sequence according to the scanning sequence; when the scanning instruction provides a key area reminder, priority can be given to the key area reminder The scan or key scan corresponds to the key area.

In step S1040, the ultrasound echo signal is processed to obtain the current ultrasound image of one or more regions.

The form of the historical ultrasound score map obtained in step S1010 may be similar to the two forms of lung ultrasound score map described in the method 200 with reference to FIGS. 3 and 4. For example, in the first form of ultrasound scoring map, the marks representing the score of the scoring result are displayed in each area of the graph of the measured object, but the ultrasound image is not displayed. In this form, the ultrasound score map may be a playback navigation interface. When a selection instruction for the mark of a certain area of the ultrasound score map is received, the ultrasound score map corresponding to the area is displayed on the display interface. image.

In the second form of the historical ultrasound scoring map, the ultrasound scoring map may include ultrasound images of corresponding regions displayed in the respective regions of the graph of the measured object, and the identification is displayed synchronously with the ultrasound image. Specifically, the logo is displayed on the ultrasound image, or the logo and the ultrasound image are displayed side by side.

In one embodiment, the scanning order of each area can be generated according to the order of the scores of each area in the historical ultrasound score map, that is, areas with higher scan scores and more severe damage are prioritized. Alternatively, the scan order of each area can also be generated according to the order of the score value of each area in the historical ultrasound score map from low to high. In another embodiment, it is also possible to compare multiple historical ultrasound score maps, and to preferentially scan for areas with improved scores.

Exemplarily, the transmitting circuit 112 shown in FIG. 1 can excite the ultrasonic probe 110 to transmit ultrasonic waves to various areas of the object under test, and receive the ultrasonic echo returned from the object under test through the receiving circuit 114 and the beam synthesis circuit 116. Wave to obtain the ultrasonic echo signal.

After that, in step S1040, the ultrasound echo signal is processed to obtain the current ultrasound image of each area. For example, the processor 118 may process the ultrasonic echo signals to obtain ultrasonic images of various regions of the object to be measured.

In one embodiment, after acquiring the current ultrasound image of one or more regions, the ultrasound imaging method 1000 further includes: identifying ultrasound signs of the current ultrasound image of the one or more regions; obtaining one or more ultrasound signs according to the ultrasound signs. The current scores of multiple regions; and, update the historical ultrasound score map according to the current scores of the one or more regions to obtain a current ultrasound score map, the current ultrasound score map including the measured object graphics and displayed on The identification of one or more regions of the measured object graph, and the identification is used to characterize the current score. For the specific details of identifying ultrasound signs, scoring according to ultrasound signs, and generating a current ultrasound score map according to the score, refer to the related descriptions in the method 200 and the method 900, and will not be repeated here.

In one embodiment, when the current ultrasound score map is generated, the identification of the area where the score has changed may be highlighted on the current ultrasound score map. That is to say, if the score of a certain area in the current ultrasound scoring map has changed from the score of the corresponding area in the historical ultrasound scoring map acquired in step S1010, the indicator of the region will be highlighted.

In the ultrasound imaging method 1000 according to another embodiment of the present application, the current ultrasound diagnosis scan is guided based on the historical ultrasound score chart, which can make the ultrasound diagnosis more targeted. For application scenarios such as physical examinations, it is conducive to rational use of historical physical examination data to achieve long-term tracking and focused attention.

Referring now to FIG. 1 again, an embodiment of the present invention also provides an ultrasound imaging system 100. The ultrasound imaging system 100 may be used to implement the above-mentioned method 200, method 900, or method 1000. The ultrasound imaging system 100 may include an ultrasound probe 110, a transmitting circuit 112, a receiving circuit 114, a beam combining circuit 116, a processor 118, a display 120, a transmitting/receiving selection switch 122, and some or all of the components in the memory 124, and the correlation of each component The description can refer to the above.

The transmitting circuit 112 is used to excite the ultrasonic probe 110 to transmit ultrasonic waves to the target object. The receiving circuit 114 is used to control the ultrasonic probe 110 to receive the ultrasonic echo returned from the target object to obtain the ultrasonic echo signal. The processor 118 is configured to: process the ultrasound echo signals to obtain an ultrasound image of the lung; identify the ultrasound signs of each lung area in the lung ultrasound image; and score each lung area according to the ultrasound signs To generate scoring results. The memory 124 is configured to store programs executed by the processor 118. The display 120 is used to display a lung ultrasonography scoring map on a display interface, the lung ultrasonography scoring map including a lung graphic and an identifier displayed at each lung region of the lung graphic, and the identifier is used to characterize all of the corresponding lung regions. Describe the scoring results.

The processor 118 may execute step S210 to step S230 in the method 200 described above in conjunction with FIG. 2, and the display 120 may execute step S240 in the method 200. In the following, only the main functions of the ultrasound imaging system 100 are described, and the details that have been described above are omitted.

In one embodiment, the identifiers in the lung ultrasound score map displayed on the display 120 include graphics that represent the score in different colors, brightness, texture, texture density, patterns, pattern density, filling area, and/or shape. The score of the result is high or low.

Exemplarily, the identification includes color blocks or color boxes of different colors, and each color block or color box represents a score of the scoring result. Further, the mark may also include the score value of the scoring result displayed in the color block or color box.

As an example, the embodiment of the present invention proposes two forms of lung ultrasound scoring chart. A form of a lung ultrasonography chart is shown in Figure 3, which displays a mark on the lung graph. At this time, the lung ultrasonography chart is a playback navigation interface. When the processor 118 receives a certain lung area of the lung ultrasonography chart When an instruction is selected for the mark, the display 120 displays the lung ultrasound image corresponding to the lung area on the display interface. Wherein, each lung area corresponds to one or more frames of the lung ultrasound images stored in the memory 124.

Another form of lung ultrasound scoring chart is shown in Figure 4.
