[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Follicle monitoring is real-time and continuous. The errors introduced by different doctors' different habits of manually marking measurement points greatly affect the follicle monitoring effect. At the same time, due to the different manifestations of follicles on different sections, it is impossible to accurately find the optimal section of the follicles during the measurement process, and repeated measurements may occur. Especially for doctors with little clinical experience, there may even be a situation where the optimal section of the follicles is set incorrectly. Therefore, automatic identification, tracking, and measurement of follicles are what doctors need. It can not only effectively reduce the doctor's operation and workload, but also improve the consistency of follicle measurement and reduce the measurement errors caused by manual measurement.

[0052] In order to solve the problem of finding the optimal section of the follicle, the prior art has also proposed a three-dimensional follicle monitoring method. However, the current three-dimensional follicle monitoring method has the following problems: (1) When one follicle is close to another follicle, it is easy to be difficult to effectively distinguish the two follicles; (2) The three-dimensional probe is heavy and expensive, and cannot be generally used for daily examinations.

[0053] Therefore, in order to solve the current problem of follicle monitoring, this application proposes a follicle measurement method based on two-dimensional ultrasound images. Figure 1 , Figure 1 It is a flow chart of an embodiment of the follicle measurement method provided in the present application. The follicle measurement method of the present application is applied to an ultrasound device, which may be a terminal device such as a smart phone, a tablet computer, a laptop computer, a car computer or a wearable device.

[0054] like Figure 1 As shown, the follicle measurement method of this embodiment specifically includes the following steps:

[0055] S101: Acquire multiple continuous ultrasound image frames.

[0056] The ultrasound device acquires multiple consecutive frames of ultrasound images, which are two-dimensional ultrasound images and contain at least one follicle. Figure 2 Ultrasound image shown.

[0057] Furthermore, the ultrasound device can be scanned in real time by the ultrasound device. Specifically, the user can preset the scanning time by the ultrasound device. The user operates the scanning probe within the preset scanning time to obtain a plurality of continuous frames of ultrasound images.

[0058] The ultrasound device can also obtain recorded ultrasound videos and capture video clips from the ultrasound videos according to user instructions or preset scanning duration to segment multiple continuous frames of ultrasound images.

[0059] Further, before measuring the ultrasonic image to be measured, it can be checked whether the automatic measurement function is turned on. When the automatic measurement function is turned on, the ultrasonic image to be measured can be measured; and when the automatic measurement function is not turned on, the user can be reminded to turn on the automatic measurement function. Among them, the automatic measurement function can be started according to an external input signal, and the external input signal can be sent by an external device, or it can be generated by triggering a preset button. The preset button can be a preset virtual button on a certain interactive interface of the touch screen of the ultrasonic diagnostic device, or it can be a preset virtual button on a fixed position of the touch screen, or it can be a physical button on the operation panel of the ultrasonic diagnostic device. When the preset button is triggered, an external input signal will be generated to start the automatic measurement function, and the automatic measurement function can also be turned off by the preset button. In this way, by controlling the on / off of the automatic measurement function, it is possible to switch between automatic measurement and manual measurement, so that the user can select the identification method according to actual needs, which brings convenience to the user. Of course, it is worth explaining that the automatic measurement function can be turned on before the ultrasonic image to be measured is obtained, or it can be turned on after the ultrasonic image to be measured is obtained.

[0060] Specifically, after acquiring multiple consecutive frames of ultrasound images, the ultrasound device can detect whether an external input signal is received, wherein the external input signal is used to start or detect whether the automatic measurement function is started.

[0061] If the ultrasound device does not receive an external input signal, it means that the automatic measurement function is not turned on, and the ultrasound device continues to scan the ultrasound image without performing subsequent measurement steps. If the ultrasound device receives an external input signal, it means that the automatic measurement function is turned on, and the ultrasound device performs subsequent steps to measure the follicles carried in the ultrasound images of multiple consecutive frames.

[0062] S102: Identify a target follicle in one frame of ultrasound images among multiple frames of ultrasound images, and obtain first shape information of the target follicle.

[0063] Here, the target follicles may be all the follicles in the ultrasound image, or may be the follicles selected in the ultrasound image.

[0064] The ultrasound device may select the first frame of multiple ultrasound images for identification, or may select any frame of multiple ultrasound images for identification. The ultrasound device may pre-process the ultrasound image frame according to a preset algorithm to obtain the contour of the target follicle in the ultrasound image frame.

[0065] Specifically, the ultrasound device performs preprocessing on the ultrasound image to be measured, including an enhancement process and a segmentation process. The enhancement process is to perform image enhancement on the ultrasound image to be measured to enhance the grayscale difference between the target object and the adjacent image. The segmentation process is to perform image segmentation on the enhanced ultrasound image to be measured to obtain the single-pixel contour line information of the target follicle. In a possible implementation of this embodiment, the preprocessing process can be implemented by a segmentation neural network, the input item of the segmentation neural network is the ultrasound image to be measured, and the output item is the edge line information of the target follicle carried by the ultrasound image to be measured. Among them, the segmentation neural network can select a deep network structure such as u-net, and is trained based on the training data including the standard section data of the follicle and the corresponding follicle of the data set after being annotated by the doctor, so that the segmentation neural network can identify the edge line of the target follicle carried by the ultrasound image to be measured. Of course, in practical applications, the segmentation neural network can be used only to segment the target object. After the target object is segmented, the sobel edge detection method can be used to obtain the edge line data of the target follicle.

[0066] The ultrasound device fits edge lines on the ultrasound image based on the edge line data obtained by preprocessing, so as to display the position and state of the follicle on the ultrasound image, wherein the first shape information of the target follicle includes at least edge line information, and the edge line information is the position and state of the edge line on the ultrasound image.

[0067] In the above steps, the ultrasound device may use all target follicles identified in the ultrasound image as target follicles to be tracked, or may select one or more target follicles as target follicles to be tracked according to preset requirements or preset instructions to continue subsequent tracking and identification.

[0068] Furthermore, in a possible implementation of this embodiment, the ultrasound device displays all target follicles in the ultrasound image by fitting edge lines. When the user needs to track and identify a target follicle, the user outputs a selection instruction by operating a button or clicking on the corresponding target follicle on the touch screen. Then, the ultrasound device uses the target follicle corresponding to the selection instruction as the target follicle to be tracked according to the selection instruction.

[0069] After the ultrasound device determines the target follicle to be tracked, Figure 2 The displayed ultrasound image can be updated to hide the contours of other target follicles except the target follicle to be tracked, or can be updated to highlight the contours of the target follicle to be tracked, such as Figure 3 The target follicle 5 in the ultrasound image in the figure is used to highlight the position and state of the target follicle to be tracked in the ultrasound image. The following steps are applicable to the tracking measurement of all target follicles by the ultrasound device, and are also applicable to the tracking measurement of the selected target follicle to be tracked by the ultrasound device. The user can select one of the methods according to the needs.

[0070] Furthermore, in another possible implementation of this embodiment, if the user does not need to measure all target follicles in the ultrasound image, the ultrasound device can not only select the target follicles to be tracked according to the selection instructions input by the user, but also eliminate some target follicles in the ultrasound image according to preset conditions.

[0071] Specifically, in order to describe the target follicle more clearly, the first shape information of the target follicle further includes the long diameter and the short diameter. First, the ultrasound device needs to fit the long diameter and the short diameter of each target follicle according to the contour line of each target follicle. For example, the ultrasound device obtains the contour line of a target follicle, calculates the straight-line distance between any two contour points on the contour line of the target follicle by traversing, and obtains the two contour points corresponding to the maximum straight-line distance, and connects the two contour points to fit the long diameter of the target follicle. After obtaining the long diameter of the target follicle, the ultrasound device uses the line formed by the two contour points in the contour line of the target follicle, which is perpendicular to the long diameter and passes through the midpoint of the long diameter as the short diameter of the target follicle.

[0072] Then, the ultrasound device calculates the shape and size values ​​of the target follicle according to the long diameter and short diameter of the target follicle. For example, the ultrasound device calculates one or more shape and size values ​​such as the volume, area and average value of the target follicle according to the long diameter length and short diameter length of the target follicle, and the above calculated values ​​can be used as the first shape information of the target follicle.

[0073] On the one hand, the ultrasound device can compare the shape size value of the target follicle with the preset shape size threshold, and take the target follicle corresponding to the shape size value greater than or equal to the preset shape size threshold as the target follicle to be tracked. On the other hand, the ultrasound device can also sort the target follicles from large to small according to the shape size value, so that the target follicles corresponding to the preset number of shape size values ​​in the front sorting are taken as the target follicles to be tracked.

[0074] In the above manner, the ultrasound device can automatically screen the target follicles in the ultrasound image without human interference, so as to reduce the workload of the ultrasound device in subsequent tracking and measurement tasks, and also improve the pertinence and accuracy of the measurement of the target follicles.

[0075] S103: Track and identify the target follicle in other frames of ultrasound images to obtain second shape information of the target follicle.

[0076] The tracking in the present application refers to that the ultrasound device uses the target follicle in S102 as a reference and searches for the position of the target follicle in other frames of ultrasound images by setting labels or positioning.

[0077] The first shape information and the second shape information are both shape information of the target follicle. Figure 2 After the target follicles are Figure 2 The shape information of the target follicles in the image is recorded and marked to configure a unique tracking ID for each target follicle. The tracking ID can be used as a unique label for each target follicle to identify the corresponding target follicle. The ultrasound device uses these tracking IDs to identify the target follicles. Figure 2 The ultrasound image is tracked and identified in other adjacent ultrasound images.

[0078] In a possible implementation of this embodiment, the ultrasound device can also track the target follicles in other frames of ultrasound images through a cross-correlation algorithm or a block matching algorithm based on the first shape information of the target follicle in S102. Specifically, the ultrasound device can obtain the contours of the target follicles in different frames of ultrasound images through a cross-correlation algorithm or a block matching algorithm, thereby matching the target follicles with high contour similarity in different frames of ultrasound images as the same target follicle.

[0079] S104: Displaying the first shape information and / or the second shape information in multiple frames of ultrasound images.

[0080] The ultrasound device can display the position and state of the target follicle in multiple frames of ultrasound images based on the first shape information and / or the second shape information. If the first shape information and the second shape information respectively include the contour line information of the target follicle, such as Figure 2 As shown, the ultrasound device displays the contour of the target follicle in the ultrasound image. If the first shape information and the second shape information also include long diameter information and short diameter information, such as Figure 3 As shown, the ultrasound device further displays the long axis and short axis of the target follicle in the ultrasound image.

[0081] After the ultrasound device obtains the target follicles in all frames of ultrasound images, it compares the shape information of the same target follicle in different frames of ultrasound images to obtain the ultrasound image with the best shape information of the target follicle as the optimal frame for identifying the target follicle.

[0082] Specifically, the ultrasound device compares the shape information of the same target follicle in different frames of ultrasound images, and the shape information used for comparison includes but is not limited to: the length of the major axis, the length of the minor axis, or the volume, area, average value, etc. calculated from the major axis and the minor axis. Taking the shape information as area as an example, the ultrasound device obtains the maximum area of ​​the same target follicle in different frames of ultrasound images, and uses the ultrasound image corresponding to the maximum area as the optimal frame for identifying the target follicle, wherein the shape information in the optimal frame is the optimal shape information of the target follicle.

[0083] The ultrasound device traverses all target follicles in the ultrasound image to obtain the optimal frame and optimal shape information corresponding to each target follicle, and records the optimal shape information of each target follicle as the measurement result of the target follicle.

[0084] In a possible implementation of this embodiment, the ultrasound device can also select the optimal frame of the target follicle according to the selection instruction input by the user, which will not be described in detail here.

[0085] In this embodiment, the ultrasound device acquires multiple continuous ultrasound images; identifies the target follicle in one ultrasound image frame in the multiple ultrasound images, and acquires the first shape information of the target follicle; tracks and identifies the target follicle in other ultrasound images, and acquires the second shape information of the target follicle; and displays the first shape information and the second shape information in the multiple ultrasound images. The follicle measurement method of the present application can automatically track the target follicle.

[0086] for Figure 1 After S104 in the illustrated embodiment, the present application further proposes another specific follicle measurement method. Figure 4 , Figure 4 It is a flow chart of another embodiment of the follicle measurement method provided in the present application.

[0087] like Figure 4 As shown, the follicle measurement method of this embodiment specifically includes the following steps:

[0088] S201: Record the measurement results of the target follicle.

[0089] The ultrasound device records the measurement results of the target and enters the measurement results into a report. The measurement results may include the first shape information and the second shape information in the above embodiment, such as the long diameter, short diameter, contour line, and area, volume, average value and other measurement values ​​of the target follicle.

[0090] Specifically, if the ultrasound device has not selected the target follicle to be tracked in the above embodiment, the measurement results of all target follicles in the ultrasound image are input into the report; if the ultrasound device has selected the target follicle to be tracked in the above embodiment, the measurement results of the target follicle to be tracked in the ultrasound image are input into the report. Further, the tracking ID of the target follicle can also be input into the report, wherein the tracking ID can be used for subsequent long-term monitoring of the corresponding target follicle.

[0091] S202: Acquire a plurality of consecutive frames of subsequent ultrasonic images, and obtain third shape information of the target follicle in the subsequent ultrasonic images.

[0092] Among them, the ultrasound device obtains the subsequent ultrasound image after the acquisition time of the continuous multiple frames of ultrasound images in the above embodiment. The number of frames of the subsequent ultrasound image can be the same as the number of frames in the above embodiment, and the number of frames obtained can also be reset according to the needs of the user. The ultrasound device locates the position of the target follicle in the subsequent ultrasound image according to the tracking ID, and calculates the third shape information of the target follicle in the subsequent ultrasound image using the method of the above embodiment, which will not be repeated here. Among them, the specific information content of the third shape information is the same as the first shape information and the second shape information in the above embodiment, which will not be repeated here.

[0093] S203: Obtain subsequent measurement results of the target follicle based on the third shape information.

[0094] The method of obtaining the subsequent measurement results in S203 is the same as the method of obtaining the measurement results in the above embodiment, which will not be described in detail. After the ultrasonic device obtains the subsequent measurement results, it also enters the subsequent measurement results into the report.

[0095] S204: Outputting a development curve of the target follicle according to the measurement result and subsequent measurement results.

[0096] Among them, the ultrasound equipment calculates the development status of the target follicle based on the measurement results of the same target follicle in the report and the subsequent measurement results, which can be specifically reflected in the form of a development curve.

[0097] Specifically, the development curve is generated based on the current measurement result and all measurement data before the current measurement, and the development curve may be for a specific target object. Figure 5 As shown, the development curve takes time as the horizontal coordinate and the follicle size as the vertical coordinate. Each development curve represents the development trend of each follicle, which is convenient for users to intuitively observe the development of each follicle and timely control the ovulation time. Among them, the follicle size can be represented by the longest diameter according to the clinical situation, or by volume or area. The area is the area within the contour line, and the volume size can be estimated according to the long diameter and the short diameter. Of course, in practical applications, there may be a problem that a follicle stops developing during the development process, so the development curve of the largest follicle can also be drawn, wherein the development curve of the largest follicle takes time as the horizontal coordinate and the follicle size as the vertical coordinate. Each point in the development curve represents the size of the largest follicle measured at its corresponding measurement moment. Among them, the development curve can be started according to an external input signal, and the external input signal can be generated according to a preset button. The preset button can be a preset virtual button on a certain interactive interface of the touch screen of the ultrasonic diagnostic device, or a preset virtual button at a fixed position on the touch screen, or a physical button on the operation panel of the ultrasonic diagnostic device.

[0098] In this application, the ultrasound device can automatically complete the measurement and tracking of the target follicle through the above operation steps. The user only needs to operate the ultrasound probe and click the preset button to start the automatic measurement function to obtain the optimal frame and optimal measurement result of the target follicle; at the same time, the measurement result is input into the report. There is no need to select a multi-level menu in the interactive interface. And it can realize automatic tracking of the target follicle during real-time scanning, helping the user to effectively distinguish the performance of the target follicle on different ultrasound images, and find the optimal frame of the target follicle according to the preset algorithm. It can greatly improve the user's measurement efficiency, especially for users with insufficient ultrasound experience, helping users find the optimal section of the target follicle. And the results are presented in the form of a curve, so that the user can intuitively observe the measurement results.
