Description

[0001] This application is a divisional application of the application with the application date of December 10, 2020, application number 2020114576939, and invention creation name "Dynamic display method for region of interest, ultrasonic imaging device, and storage medium". Technical Field

[0002] This application relates to the field of ultrasonic imaging technology, and more particularly to a dynamic display method for a region of interest, an ultrasonic imaging device, and a storage medium. Background Art

[0003] Ultrasonic instruments are generally used for doctors to observe the internal tissue structure of the human body. Doctors place the operating probe on the skin surface corresponding to the human body part to obtain ultrasonic images of that part. Due to its characteristics such as safety, convenience, non-invasiveness, and low cost, ultrasound has become the main auxiliary means for doctors to make diagnoses.

[0004] When existing ultrasonic instruments perform ultrasonic imaging, they do not provide a comparison display scheme for the states of the same region of interest at different times. However, in some scenarios, doctors need to compare and study the states of the same region of interest at different times. For example, when doctors analyze the endometrial peristaltic wave, they need to compare and study the states of the relevant regions generating the peristaltic wave at different times to analyze the characteristics of muscle contraction and relaxation, but the existing solutions cannot achieve such comparison display.

[0028] In order to make the objectives, technical solutions and advantages of the present application more apparent, exemplary embodiments according to the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described herein. Based on the embodiments of the present application described herein, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0029] First, with reference to Figure 1 an exemplary ultrasonic measurement device for implementing a method for dynamically displaying a region of interest according to an embodiment of the present application will be described.

[0030] Figure 1 A schematic block diagram of an exemplary ultrasonic measurement device 10 for implementing a method for dynamically displaying a region of interest according to an embodiment of the present application is shown. As Figure 1As shown, the ultrasonic measurement 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 may excite the ultrasonic probe 100 to transmit ultrasonic waves to a target object (the object to be measured), and may also control the ultrasonic probe 100 to receive ultrasonic echoes returned from the target object, so as to obtain 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 may be stored in the memory 105, and these ultrasonic images may be displayed on the display 104. It should be noted that the target object involved in this application may be a human or a veterinary animal, such as a cat, a dog, a rabbit, etc., and no specific limitation is made here.

[0031] In an embodiment of this application, the display 104 of the aforementioned ultrasonic measurement device 10 may be a touch display screen, a liquid crystal display screen, etc., or may also be an independent display device such as a liquid crystal display or a television outside the ultrasonic measurement device 10, or may also be a display screen on an electronic device such as a mobile phone or a tablet computer.

[0032] In an embodiment of this application, the memory 105 of the aforementioned ultrasonic measurement device 10 may be a flash card, a solid-state memory, a hard disk, etc.

[0033] An embodiment of this application also provides a computer-readable storage medium, which stores multiple program instructions. After being called and executed by the processor 103, the multiple program instructions can execute some steps or all steps or any combination of the steps in the dynamic display method of the region of interest in each embodiment of this application.

[0034] 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 card, a solid-state memory, or a hard disk.

[0035] In the embodiments of the present application, the processor 103 of the aforementioned ultrasonic measurement device 10 can be implemented by software, hardware, firmware, or a combination thereof. 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 can be used, 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 frames, points, lines, etc., and no specific limitation is made here. That is, the region of interest can be any one of graphics such as points, lines, frames, etc., and can be determined according to the actual situation specifically.

[0036] Next, in conjunction with Figures 2 to 7 a detailed description of the dynamic display method of the region of interest of the present application will be given. This method can be executed by the aforementioned ultrasonic measurement device 10.

[0037] Figure 2 FIG. shows a schematic flowchart of a dynamic display method 200 of a region of interest according to an embodiment of the present application. As Figure 2 shown, the dynamic display method 200 of the region of interest includes the following steps:

[0038] In step S210, control the ultrasonic probe to emit a first ultrasonic wave towards the target region of the target object and receive the ultrasonic echo based on the first ultrasonic wave to obtain a first ultrasonic echo signal.

[0039] In step S220, generate a first ultrasonic image in real time according to the first ultrasonic echo signal, obtain at least one region of interest in the first ultrasonic image, and determine the position information of the at least one region of interest as the initial position information.

[0040] In step S230, control the ultrasonic probe to emit a second ultrasonic wave towards the target region and receive the ultrasonic echo based on the second ultrasonic wave to obtain a second ultrasonic echo signal.

[0041] In step S240, generate a second ultrasonic image in real time according to the second ultrasonic echo signal, and track the position information of the at least one region of interest in the second ultrasonic image as the real-time position information of the at least one region of interest.

[0042] In step S250, dynamically display the generated ultrasonic image, and display the initial position information of the at least one region of interest on the first ultrasonic image, and display the initial position information and the corresponding real-time position information of the at least one region of interest on the second ultrasonic image.

[0043] In an embodiment of the present application, controlling an ultrasonic probe to emit a first ultrasonic wave towards a target area (such as a tissue area) of a target object (such as a patient) is 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 frame 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 may also be the first few frame images obtained by scanning, as long as the region of interest can be determined. Correspondingly, 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 other areas default or selected by the user outside the uterine area. In addition, the region of interest may be the area where peristaltic waves are generated, or other areas default or selected by the user. No specific limitation is made here.

[0044] After determining the region of interest and its initial position information, the ultrasonic probe can be controlled to continue to emit a second ultrasonic wave towards the target area of the target object, which is to generate a second ultrasonic image to track the position change of the region of interest previously determined according to the first ultrasonic image over time in the second ultrasonic image. 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 to say, for each frame of the second ultrasonic image, the position of the aforementioned region of interest in this frame image can be determined as the real-time position information of the region of interest in the current frame image.

[0045] In an embodiment of the present application, the generated ultrasonic images, such as the aforementioned first ultrasonic image and second ultrasonic image, are dynamically displayed. Since the initial position information of the region of interest is displayed in the first ultrasonic image, and in the second ultrasonic image, in addition to displaying the real-time position information of the region of interest in the current image, the initial position information (the position information in the first ultrasonic image) of the region of interest is also displayed. Therefore, the user can clearly see the position change of the same region of interest in the second ultrasonic image, so as to be able to compare and study the motion state of the same region of interest.

[0046] In addition, since the number of regions of interest determined based on 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 respective motion states 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.

[0047] In an 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 velocity of the pixel points within the region of interest (for example, calculating the displacement between every two frames according to methods such as speckle tracking) and performing superposition, and continuously updated. The following will be described in conjunction with Figure 3 to describe.

[0048] Figure 3 FIG. shows a schematic diagram of tracking the real-time position of pixel points within a region of interest in a method for dynamically displaying a region of interest according to an embodiment of the present application. As Figure 3 shown, assume that the position (i.e., the initial position information) of a certain pixel point in the region of interest (in the first ultrasound image) is represented as coordinates (x1, y1); after re-scanning, a frame of the second ultrasound image is obtained, and the position of this pixel point (in this frame of the second ultrasound image) (i.e., the real-time position information) is coordinates (x2, y2). Relative to the initial position information, it has moved dx1 horizontally and dy1 vertically; then, for another frame of the second ultrasound image obtained by re-scanning, the position of this pixel point (in this frame of the second ultrasound image) (i.e., the real-time position information) is coordinates (x3, y3). Relative to its position information in the previous frame, it has moved dx2 horizontally and dy2 vertically. Similarly, for other pixel points in the region of interest, the position information of other pixel points can be tracked in the same way, so as to obtain the real-time position information of tracking the region of interest.

[0049] In an embodiment of the present application, the display of the initial position information and the real-time position information of any region of interest may include: displaying the region of interest with a first graphic mark at the initial position corresponding to the initial position information, and displaying the region of interest with a second graphic mark at the real-time position corresponding to the real-time position information. Among them, the graphic marks of the same region of interest in different ultrasound images can 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 from each other. The following will be described in conjunction with Figures 4 to 5 exemplarily describe the dynamic display of the region of interest.

[0050] Figure 4 FIG. shows an example of a display interface in a method for dynamically displaying a region of interest according to an embodiment of the present application. As Figure 4As shown, the position of the region of interest in a frame of the second ultrasound image is shown. Among them, the dashed box 1 presents the first region of interest and its initial position, the dashed box 2 presents the second region of interest and its initial position, the solid box 3 presents the first region of interest and its real-time position in the current frame image, and the solid box 4 presents the second region of interest and its real-time position in the current frame image.

[0051] That is to say, in Figure 4 the example shown, there are two regions of interest, namely the first region of interest and the second region of interest. The initial position and real-time position of the first region of interest are shown by the dashed box 1 and the solid box 3 respectively, and the initial position and real-time position of the second region of interest are shown by the dashed box 2 and the solid box 4 respectively.

[0052] In this example, for the same region of interest, its initial position information and real-time position information are shown by different but similar graphical markers (dashed boxes and solid boxes), so that the user can clearly see the position change of the same region of interest through different icon markers. For different regions of interest, the two are represented by boxes with different colors in the same frame. For example, the first region of interest is represented by the white dashed box 1 at the initial position, and the second region of interest is represented by the black dashed box 2 at the initial position; the real-time position of the first region of interest at the current frame is represented by the light gray solid box 3, and the initial position of the second region of interest is represented by the dark gray solid box 4.

[0053] Therefore, in Figure 4 the example shown, the same region of interest is represented by different but similar icon markers in different ultrasound images (at different times). Among them, "similar" enables the user to determine that it is the same region of interest, and "different" enables the user to distinguish the initial position and the real-time position. Different regions of interest are represented by different icon markers 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 marker 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 all the time, and the real-time position changes in real time. The user can still compare and analyze the position change of the same region of interest at different times.

[0054] In a further embodiment of the present application, a reference point can also be obtained and displayed on the dynamically displayed ultrasound image. For example, as Figure 4 shown, the point O is the reference point, which enables the user to more clearly see the position change of the region of interest according to the reference function of the reference point.

[0055] In a further embodiment of the present application, a target point can also be selected as an interest point on the region of interest, and a connection line is formed by connecting the interest point and the reference point, and the connection line is displayed when the ultrasonic image is dynamically displayed. For example, as Figure 4 shown, an interest point A1 is selected on the first region of interest at the initial position, and an interest point A2 is selected on the first region of interest at the real-time position; an interest point B1 is selected on the second region of interest at the initial position, and an interest point B2 is selected on the second region of interest at the real-time position. These interest points are respectively connected to the reference point O to form connection lines. In this way, when continuously displaying multiple frames of ultrasonic images dynamically, the reference point O and the initial position of the region of interest remain unchanged all the time, that is, the connection lines A1O and B1O remain stationary, but as the real-time position of the region of interest changes, the connection lines A2O and B2O will move accordingly, and the user can more clearly see the position change of the region of interest.

[0056] In Figure 4 the example shown, the interest point 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, etc. In addition, in Figure 4 the example shown, the connection lines A1O and B1O are displayed as white dotted lines, and the connection lines A2O and B2O are shown as gray dotted lines. That is to say, the connection lines of the same region of interest with the reference point in different frames of ultrasonic images (at different times) are distinguished and displayed by different features, which can enable the user to more clearly see the comparison between the real-time position and the initial position of the region of interest.

[0057] In Figure 4 the example shown, the reference point O is selected as the center point between the two regions of interest at the initial position. That is to say, in this example, the reference point is generated according to the initial position information of the region of interest, which is only exemplary. In other examples, the reference point can also be obtained in other ways. For example, an operation instruction of the user can be obtained, and the reference point is determined according to the user operation instruction, that is, the user selects the position of the reference point; or, a preset fixed reference point of the system can also be obtained, such as the center point of the display screen, the lower left corner, or other positions, etc.

[0058] Figure 5 shows another example of the display interface in the dynamic display method of the region of interest according to an embodiment of the present application. Figure 5 The example of the display interface shown is generally similar to that shown in Figure 4 , and the difference is only that Figure 5 the position of the reference point in the example shown is different from Figure 4 the position of the reference point in the example shown.

[0059] In a further embodiment of the present application, a curve graph reflecting the motion of the region of interest can also be generated and displayed based on the position information of the region of interest in each frame of the ultrasonic image. For example, as Figure 6 shown. Figure 6 Fig. Figure 6 shows yet another example of the display interface in the dynamic display method of the region of interest according to an embodiment of the present application. Figure 6 The upper half of the display interface example shown in Fig. Figure 6 is the same as Figure 4 Fig. Figure 4 , and the lower half shows a curve graph of the motion of the region of interest. Among them, curve 610 shows the motion curve of a 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 graph of the region of interest, the user can more clearly see the motion state of the same region of interest at different times, and can also see the comparison of the motion states of different regions of interest at the same time.

[0060] In the example described in conjunction with Figures 4 to 6 Fig. Figures 4 to 6 , the region of interest is shown as a rectangular box region, which is only exemplary. In other examples, the region of interest can also be any other form, such as a point, a circle, a tracing, etc.

[0061] In the embodiment of the present application, the curve graph of the motion of a region of interest can include at least one of the following: the motion speed curve graph, the displacement curve graph, and the strain curve graph of the region of interest over a period of time. For a curve graph including at least two regions of interest, the curve graph can also include the relative distance curve graph of different regions of interest over a period of time. In the embodiment of the present application, the curve graph reflecting the motion of the region of interest can be displayed in real time along with the real-time display of the ultrasonic image, or can also be displayed after the real-time display of the ultrasonic image is completed.

[0062] In a further embodiment of the present application, at least one of the following operations may also be performed: quantifying and comparing the motion speed and / or motion direction of the same region of interest at different times based on the motion speed curve graph; quantifying and comparing the motion speed and / or motion direction of different regions of interest at the same time based on the motion speed curve graph; quantifying and comparing the motion frequencies of different regions of interest over a period of time based on the motion speed curve graph; quantifying and comparing the phase and / or the distance from the initial position of the same region of interest at different times based on the displacement curve graph; quantifying and comparing the phase difference of different regions of interest over a period of time based on the displacement curve graph; performing frequency domain analysis and comparison on the region 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 manner or a numerical manner, so that the user can more accurately view the motion of the region of interest.

[0063] 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 change of the region of interest in the ultrasonic image and dynamically display the position change of the region of interest, so that the doctor can compare and study the motion states 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 in the diagnosis work.

[0064] In an embodiment of the present application, the target region of the above-mentioned target object may include the uterine region, and the tissue region corresponding to the region of interest may include the 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 realized, which provides great support for the doctor's diagnosis.

[0065] The above exemplarily shows the dynamic display method of the region of interest according to an embodiment of the present application. Next, in combination with Figure 7 Describe the dynamic display method of the region of interest according to another embodiment of the present application.

[0066] Figure 7 Fig. shows a schematic flowchart of a dynamic display method 700 of a region of interest according to another embodiment of the present application. As Figure 7 shown, the dynamic display method 700 of the region of interest includes the following steps:

[0067] In step S710, obtain ultrasonic images collected for a period of time for the target region of the target object, determine one frame of the ultrasonic images within the period of time as the first ultrasonic image, and define at least one frame of the ultrasonic images after the first ultrasonic image as the second ultrasonic image.

[0068] In step S720, at least one region of interest in the first ultrasound image is obtained, and the position information of the at least one region of interest is determined as the initial position information.

[0069] 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.

[0070] 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 the corresponding real-time position information of the at least one region of interest are displayed on the second ultrasound image.

[0071] The method 700 for dynamically displaying a region of interest according to an embodiment of the present application is generally similar to the method 200 for dynamically displaying a region of interest according to an embodiment of the present application described above. The difference lies in that: the method 200 for dynamically displaying a region of interest according to an embodiment of the present application acquires ultrasound images in real time, determines the position information of the region of interest in real time, and displays the ultrasound images and the position information of the region of interest in each frame of ultrasound image in real time, including the initial position information and the real-time position information; while the method 700 for dynamically displaying a region of interest according to an embodiment of the present application determines the region of interest and its position information (initial position information) according to one of the ultrasound images after the acquisition of the ultrasound images within a period of time, then determines the position information (real-time position information) of the region of interest in the ultrasound images after this frame of ultrasound image, and dynamically displays the ultrasound images within this period of time and the position information of the region of interest in each frame of ultrasound image, including the initial position information and the real-time position information. For the sake of brevity, the similar details in the two methods are not described here.

[0072] Next, in conjunction with Figure 8 An ultrasonic imaging device provided according to another aspect of the present application is described, which can be used to implement the method for dynamically displaying a region of interest according to an embodiment of the present application described above.
