However, in some scenarios, doctors need to compare and study the status of the same region of interest at different times. For example, when analyzing endometrial peristaltic waves, doctors need to compare and study the status of the relevant areas that generate peristaltic waves at different times to analyze the characteristics of muscle contraction and relaxation, but existing solutions cannot achieve such comparative display.

[0027] In order to make the purpose, technical solutions and advantages of the present application more obvious, the example embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0028] First, refer to Figure 1 An exemplary ultrasonic measuring device for implementing the method for dynamically displaying a region of interest according to an embodiment of the present application is described.

[0029] Figure 1 FIG. 1 is a schematic diagram of a structural block diagram of an exemplary ultrasonic measuring device 10 for implementing the method for dynamically displaying a region of interest according to an embodiment of the present application. Figure 1As shown, the ultrasonic measuring device 10 may include an ultrasonic probe 100, a transmit / receive selection switch 101, a transmit / receive sequence controller 102, a processor 103, a display 104 and a memory 105. The transmit / receive sequence controller 102 can stimulate the ultrasonic probe 100 to transmit ultrasonic waves to the target object (measured object), and can also control the ultrasonic probe 100 to receive ultrasonic echoes returned from the target object, thereby obtaining ultrasonic echo signals / data. The processor 103 processes the ultrasonic echo signals / data to obtain tissue-related parameters and ultrasonic images of the target object. The ultrasonic images obtained by the processor 103 can be stored in the memory 105, and these ultrasonic images can be displayed on the display 104. It should be noted that the target object involved in this application can be a human or a beast, such as a cat, a dog, a rabbit, etc., which is not specifically limited here.

[0030] In the embodiment of the present application, the display 104 of the aforementioned ultrasonic measuring device 10 may be a touch screen, a liquid crystal display, etc., or may be an independent display device such as a liquid crystal display, a television, etc. independent of the ultrasonic measuring device 10, or may be a display screen on an electronic device such as a mobile phone or a tablet computer.

[0031] In the embodiment of the present application, the memory 105 of the aforementioned ultrasonic measuring device 10 may be a flash memory card, a solid-state memory, a hard disk, etc.

[0032] An embodiment of the present application also provides a computer-readable storage medium, which stores multiple program instructions. After the multiple program instructions are called and executed by the processor 103, some or all of the steps or any combination of the steps in the dynamic display method of the area of ​​interest in each embodiment of the present application can be executed.

[0033] In one embodiment, the computer-readable storage medium may be the memory 105, which may be a non-volatile storage medium such as a flash memory card, a solid-state memory, or a hard disk.

[0034] In the embodiment of the present application, the processor 103 of the aforementioned ultrasonic measuring device 10 can be implemented by software, hardware, firmware or a combination thereof, and can use circuits, single or multiple application specific integrated circuits (ASICs), single or multiple general integrated circuits, single or multiple microprocessors, single or multiple programmable logic devices, or a combination of the aforementioned circuits or devices, or other suitable circuits or devices, so that the processor 103 can execute the corresponding steps of the dynamic display method of the region of interest in each embodiment. It should be noted that the region of interest involved in the present application can be represented by graphics such as boxes, points, lines, etc., and no specific limitation is made here. That is, the region of interest can be any kind of graphics such as points, lines, boxes, etc., which can be determined according to actual conditions.

[0035] Combine the following Figures 2 to 7 The method for dynamically displaying a region of interest of the present application is described in detail. The method can be executed by the aforementioned ultrasonic measuring device 10 .

[0036] Figure 2 FIG. 2 is a schematic flow chart of a method 200 for dynamically displaying a region of interest according to an embodiment of the present application. Figure 2 As shown, the method 200 for dynamically displaying a region of interest includes the following steps:

[0037] In step S210, the ultrasonic probe is controlled to transmit a first ultrasonic wave to a target area of ​​a target object and receive an ultrasonic echo based on the first ultrasonic wave to obtain a first ultrasonic echo signal.

[0038] In step S220, a first ultrasonic image is generated in real time according to the first ultrasonic echo signal, at least one region of interest in the first ultrasonic image is acquired, and position information of the at least one region of interest is determined as initial position information.

[0039] In step S230, the ultrasonic probe is controlled to transmit a second ultrasonic wave to the target area and receive an ultrasonic echo based on the second ultrasonic wave to obtain a second ultrasonic echo signal.

[0040] In step S240, a second ultrasonic image is generated in real time according to the second ultrasonic echo signal, and position information of the at least one region of interest in the second ultrasonic image is tracked as real-time position information of the at least one region of interest.

[0041] In step S250, the generated ultrasound image is dynamically displayed, and the initial position information of the at least one region of interest is displayed on the first ultrasound image, and the initial position information and corresponding real-time position information of the at least one region of interest are displayed on the second ultrasound image.

[0042] In an embodiment of the present application, the ultrasound probe is controlled to emit a first ultrasonic wave to a target area (such as a tissue area) of a target object (such as a patient) in order to generate a first ultrasonic image to determine (manually selected by the user or automatically selected by the system) at least one region of interest, and determine the position information of the region of interest in the first ultrasonic image as initial position information, which provides a reference for the position change of the region of interest in subsequent frames of ultrasonic images. It should be understood that the first ultrasonic image here may include at least one frame of ultrasonic image. For example, the first ultrasonic image may be the first frame image obtained by scanning, or it may be the first few frames of images obtained by scanning, as long as the region of interest can be determined. Accordingly, the initial position information of the region of interest is the position information of the region of interest in the frame image in which the region of interest is determined. It should be noted that the target area involved in the present application may be the uterine area, or it may be other areas outside the uterine area that are defaulted by the system or selected by the user. In addition, the region of interest may be an area where peristaltic waves are generated, or it may be other areas that are defaulted by the system or selected by the user, which are not specifically limited here.

[0043] After determining the region of interest and its initial position information, the ultrasonic probe can be controlled to continue to transmit a second ultrasonic wave to the target area of ​​the target object, in order to generate a second ultrasonic image to track the position change of the region of interest previously determined based on the first ultrasonic image in the second ultrasonic image over time. Specifically, the position information of the region of interest in the second ultrasonic image can be determined as real-time position information. It should be understood that the second ultrasonic image here may include at least one frame of ultrasonic image. That is, for each frame of the second ultrasonic image, the position of the aforementioned region of interest in the frame image can be determined as the real-time position information of the region of interest in the current frame image.

[0044] In an embodiment of the present application, the generated ultrasound images, such as the aforementioned first ultrasound image and the second ultrasound image, are dynamically displayed. Since the initial position information of the region of interest is displayed in the first ultrasound image, and in the second ultrasound image, in addition to displaying the real-time position information of the region of interest in the current image, the initial position information of the region of interest (the position information in the first ultrasound image) is also displayed, the user can clearly see the position change of the same region of interest in the second ultrasound image, thereby being able to compare and study the motion state of the same region of interest.

[0045] In addition, since the number of regions of interest determined according to the first ultrasound image is at least one, that is, when the number of regions of interest is two or more, the user can see the motion state of each region of interest in the second ultrasound image. Moreover, in the same ultrasound image (i.e., at the same moment), the user can also see the comparison of the positions of different regions of interest.

[0046] In the embodiment of the present application, for any region of interest, the real-time position of the region of interest can be obtained by calculating the average motion displacement or speed of the pixels in the region of interest (for example, calculating the displacement of every two frames according to a method such as speckle tracking) and superimposing them, and the real-time position of the region of interest is continuously updated. Figure 3 to describe.

[0047] Figure 3 A schematic diagram showing the real-time position of pixels in a region of interest in a method for dynamically displaying a region of interest according to an embodiment of the present application is shown. Figure 3 As shown, it is assumed that the position (i.e., initial position information) of a certain pixel point in the region of interest (in the first ultrasound image) is represented by the coordinates (x1, y1); after scanning again, a second frame of the second ultrasound image is obtained, and the position (i.e., real-time position information) of the pixel point (in the second ultrasound image of the frame) is the coordinates (x2, y2), which is moved horizontally by dx1 and vertically by dy1 relative to the initial position information; then, for another second frame of the second ultrasound image obtained by scanning again, the position (i.e., real-time position information) of the pixel point (in the second ultrasound image of the frame) is the coordinates (x3, y3), which is moved horizontally by dx2 and vertically by dy2 relative to its position information in the previous frame. Similarly, for other pixel points in the region of interest, the position information of other pixel points can be tracked in the same way, thereby obtaining the real-time position information of the tracked region of interest.

[0048] In an embodiment of the present application, for any region of interest, the display of its initial position information and real-time position information may include: displaying the region of interest with a first graphic mark at an initial position corresponding to the initial position information, and displaying the region of interest with a second graphic mark at a real-time position corresponding to the real-time position information. The graphic marks of the same region of interest in different ultrasound images may be the same or similar, and the graphic marks of different regions of interest in the same ultrasound image should be different, or even significantly different, to distinguish each other. Figure 4 to Figure 5 The dynamic display of the region of interest is described exemplarily.

[0049] Figure 4 An example of a display interface in a method for dynamically displaying a region of interest according to an embodiment of the present application is shown. Figure 4As shown, the position of the region of interest in a second ultrasound image is shown. Among them, the dotted line box 1 presents the first region of interest and its initial position, the dotted line box 2 presents the second region of interest and its initial position, the solid line box 3 presents the first region of interest and its real-time position in the current frame image, and the solid line box 4 presents the second region of interest and its real-time position in the current frame image.

[0050] That is to say, Figure 4 In the example shown, two regions of interest are included, namely a first region of interest and a second region of interest, wherein the initial position and real-time position of the first region of interest are shown in a dotted box 1 and a solid box 3 respectively, and the initial position and real-time position of the second region of interest are shown in a dotted box 2 and a solid box 4 respectively.

[0051] In this example, for the same region of interest, its initial position information and real-time position information are shown with different but similar graphic marks (dashed box and solid box), and the user can clearly see the position change of the same region of interest through different icon marks. For different regions of interest, the two are represented by boxes of different colors in the same frame, for example: the first region of interest is represented by a white dashed box 1 at the initial position, and the second region of interest is represented by a black dashed box 2 at the initial position; the first region of interest is represented by a light gray solid box 3 at the real-time position of the current frame, and the second region of interest is represented by a dark gray solid box 4 at the initial position.

[0052] Therefore, in Figure 4 In the example shown, the same region of interest is represented by different but similar icon marks in different ultrasound images (at different times), where "similar" allows the user to determine that it is the same region of interest, and "different" allows the user to distinguish the initial position and the real-time position. Different regions of interest are represented by different icon marks in the same ultrasound image (at the same time) to distinguish each other. In other examples, the same region of interest can also be represented by the same icon mark in different ultrasound images, because the initial position and real-time position of the region of interest can be displayed in each frame of the second ultrasound image, the initial position remains unchanged, and the real-time position changes in real time, and the user can still compare and analyze the position changes of the same region of interest at different times.

[0053] In a further embodiment of the present application, a reference point may be obtained and displayed on the dynamically displayed ultrasound image, for example Figure 4 As shown, point O is the reference point, which enables the user to more clearly see the position change of the area of ​​interest based on the reference function of the reference point.

[0054] In a further embodiment of the present application, a target point may be selected as an interest point on the region of interest, the interest point and the reference point may be connected to form a line, and the line may be displayed when the ultrasound image is dynamically displayed. Figure 4 As shown, the point of interest A1 is selected on the first region of interest at the initial position, and the point of interest A2 is selected on the first region of interest at the real-time position; the point of interest B1 is selected on the second region of interest at the initial position, and the point of interest B2 is selected on the second region of interest at the real-time position. These points of interest are respectively connected with the reference point O to form lines, so that when the continuous multi-frame ultrasound image is dynamically displayed, the initial positions of the reference point O and the region of interest remain unchanged, that is, the lines A1O and B1O remain stationary, but as the real-time position of the region of interest changes, the lines A2O and B2O will move accordingly, and the user can more clearly see the position change of the region of interest.

[0055] exist Figure 4 In the example shown, the point of interest selected on the region of interest is the center point of the region of interest, which is only exemplary. In other examples, it can also be any point on the region of interest, such as a point on the bounding box of the region of interest. Figure 4 In the example shown, lines A1O and B1O are displayed as white dotted lines, and lines A2O and B2O are displayed as gray dotted lines. That is, the lines connecting the same region of interest and the reference points in different frames of ultrasound images (at different times) are distinguished and displayed using different features, so that the user can more clearly see the comparison between the real-time position and the initial position of the region of interest.

[0056] exist Figure 4 In the example shown, the reference point O is selected as the center point between the two regions of interest when they are in the initial position. That is, in this example, the reference point is generated based on the initial position information of the regions of interest. This is only exemplary. In other examples, the reference point can also be obtained in other ways. For example, the user's operation instruction can be obtained, and the reference point is determined according to the user's operation instruction, that is, the user selects the position of the reference point; or, a fixed reference point preset by the system can also be obtained, such as the center point of the display screen, the lower left corner, or other positions.

[0057] Figure 5 Another example of a display interface in a method for dynamically displaying a region of interest according to an embodiment of the present application is shown. Figure 5 The display interface example shown is similar to Figure 4 are substantially similar to those shown, differing only in that Figure 5 The reference point positions in the example shown are Figure 4 The reference points in the examples shown are located differently.

[0058] In a further embodiment of the present application, a curve graph reflecting the movement of the region of interest may be generated and displayed based on the position information of the region of interest in each frame of ultrasound image, for example: Figure 6 shown. Figure 6 Another example of a display interface in a method for dynamically displaying a region of interest according to an embodiment of the present application is shown. Figure 6 The upper part of the display example shown is the same as Figure 4 Similarly, the lower part shows a curve diagram of the motion of the region of interest. Among them, curve 610 shows the motion curve of one region of interest over time, and curve 620 shows the motion curve of another region of interest over time. Based on the displayed motion curve diagram of interest, the user can more clearly see the motion status of the same region of interest at different times, and can also see the comparison of the motion status of different regions of interest at the same time.

[0059] In combination Figures 4 to 6 In the described example, the region of interest is shown as a rectangular frame area, which is only exemplary. In other examples, the region of interest can also be any other form, such as a point, a circle, a trace, etc.

[0060] In an embodiment of the present application, a graph of the motion of a region of interest may include at least one of the following: a velocity graph, a displacement graph, and a strain graph of the region of interest over a period of time. For a graph including at least two regions of interest, the graph may also include a relative distance graph of different regions of interest over a period of time. In an embodiment of the present application, a graph reflecting the motion of the region of interest may be displayed in real time along with the real-time display of the ultrasound image, or may be displayed after the real-time display of the ultrasound image ends.

[0061] In a further embodiment of the present application, at least one of the following operations may also be performed: based on the motion speed curve, quantify and compare the motion speed and / or motion direction of the same region of interest at different times; based on the motion speed curve, quantify and compare the motion speed and / or motion direction of different regions of interest at the same time; based on the motion speed curve, quantify and compare the motion frequency of different regions of interest over a period of time; based on the displacement curve, quantify and compare the phase and / or distance from the initial position of the same region of interest at different times; based on the displacement curve, quantify and compare the phase difference of different regions of interest over a period of time; perform frequency domain analysis and comparison on the regions of interest. Based on the above quantification and comparison, the motion of the region of interest can be quantitatively analyzed. Exemplarily, the results of the above comparison can be displayed in a curve or numerical form, so that the user can view the motion of the region of interest more accurately.

[0062] Based on the above description, the dynamic display method of the region of interest according to the embodiment of the present application can dynamically track the position changes of the region of interest in the ultrasound image, and dynamically display the position changes of the region of interest, so that the doctor can compare and study the movement state of the same region of interest, and when two or more regions of interest are included, the positions of different regions of interest at the same time can also be compared and studied, thereby better assisting the doctor's diagnosis work.

[0063] In an embodiment of the present application, the target area of ​​the target object described above may include a uterine area, and the tissue area corresponding to the region of interest may include tissue that generates peristaltic waves. In this embodiment, based on the dynamic display method of the region of interest of the present application, qualitative and quantitative peristaltic wave detection can be achieved, providing great support for the doctor's diagnosis.

[0064] The above is an exemplary method for dynamically displaying a region of interest according to an embodiment of the present application. Figure 7 A method for dynamically displaying a region of interest according to another embodiment of the present application is described.

[0065] Figure 7 FIG. 7 is a schematic flow chart of a method 700 for dynamically displaying a region of interest according to another embodiment of the present application. Figure 7 As shown, the method 700 for dynamically displaying a region of interest includes the following steps:

[0066] In step S710, ultrasonic images collected within a period of time for a target area of ​​a target object are acquired, a frame of ultrasonic images in the period of time is determined as a first ultrasonic image, and at least one frame of ultrasonic image after the first ultrasonic image is defined as a second ultrasonic image.

[0067] In step S720, at least one region of interest in the first ultrasound image is acquired, and position information of the at least one region of interest is determined as initial position information.

[0068] In step S730, the position information of the at least one region of interest in the second ultrasound image is tracked as the real-time position information of the at least one region of interest.

[0069] In step S740, the ultrasound images within the period of time are dynamically displayed, and the initial position information of the at least one region of interest is displayed on the first ultrasound image, and the initial position information and corresponding real-time position information of the at least one region of interest are displayed on the second ultrasound image.

[0070] The dynamic display method 700 of the region of interest according to the embodiment of the present application is substantially similar to the dynamic display method 200 of the region of interest according to the embodiment of the present application described above, except that: the dynamic display method 200 of the region of interest according to the embodiment of the present application acquires ultrasonic images in real time, determines the position information of the region of interest in real time, and displays the ultrasonic images and the position information of the region of interest in each frame of the ultrasonic image in real time, including the initial position information and the real-time position information; while the dynamic display method 700 of the region of interest according to the embodiment of the present application determines the region of interest and its position information (initial position information) according to one frame of the ultrasonic image after a period of ultrasonic image acquisition is completed, and then determines the position information (real-time position information) of the region of interest in the ultrasonic image after the frame of the ultrasonic image, and dynamically displays the ultrasonic images within the period of time and the position information of the region of interest in each frame of the ultrasonic image, including the initial position information and the real-time position information. For the sake of brevity, similar details in the two methods are not described here.

[0071] Combine the following Figure 8 An ultrasonic imaging device provided according to another aspect of the present application is described, which can be used to implement the above-mentioned method for dynamically displaying a region of interest according to an embodiment of the present application.

Figure 8As shown, the ultrasonic imaging device 800 may include a transmit / receive sequence controller 810, an ultrasonic probe 820, a processor 830, and a display 840. The transmit / receive sequence controller 810 is used to control the ultrasonic probe 820 to transmit ultrasonic waves to the target area of ​​the target object, and receive ultrasonic echoes based on the ultrasonic waves to obtain ultrasonic echo signals; the processor 830 is used to perform the above-described method for dynamically displaying the region of interest according to the embodiment of the present application based on the ultrasonic echo signals; and the display 840 is used to display under the control of the processor 830.
