[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please refer to Figure 1 , Figure 1 A flowchart illustrating a follicle counting method provided in an embodiment of the present invention. The method may include:

[0042] Step 101: Start the counting function according to the preset trigger signal.

[0043] The counting function in this step can be an automatic counting function of follicles in the ultrasound images to be counted (such as ovarian ultrasound images). The specific settings of the counting function in this step can be customized by the designer according to the practical scenario and user needs. For example, the counting function can be a function of counting follicles in all or part of the image frames in the real-time acquired ultrasound images (i.e., real-time ultrasound images) within the counting cycle; the counting function can also be a function of counting follicles in all or part of the image frames in the received or stored ultrasound video. This embodiment does not impose any limitations on this.

[0044] Specifically, the preset trigger signal in this step can be a signal that controls the start of the counting function. The specific triggering method for this preset trigger signal can be set by the designer according to the practical scenario and user needs. For example, the preset trigger signal can be a signal triggered by a switch on the ultrasound device's probe (such as a toggle switch), a key on the keyboard, and / or a virtual key on the touchscreen to control the start of the counting function; that is, in this step, the ultrasound device can start the counting function based on the preset trigger signal triggered by the switch on the ultrasound device's probe, a key on the keyboard, or a virtual key on the touchscreen.

[0045] Correspondingly, to avoid accidental activation of the counting function, in this step, the ultrasound device can activate the counting function in B-mode based on a preset trigger signal triggered by a switch on the ultrasound probe, a key on the keyboard, or a virtual key on the touchscreen. For example, in B-mode, the ultrasound device can activate the counting function based on a preset trigger signal triggered by a switch on the ultrasound probe; for instance, when the ultrasound device is in B-mode, the user can press the button switch on the ultrasound probe or toggle the switch on the probe to trigger the preset trigger signal and control the ultrasound device to activate the counting function. Alternatively, in B-mode, the ultrasound device can activate the counting function based on a preset trigger signal triggered by the ultrasound device's keyboard or touchscreen (such as a control panel or touchscreen display); for instance, when the ultrasound device is in B-mode, the user can trigger the preset trigger signal and control the ultrasound device to activate the counting function by pressing the count-on button on the keyboard or clicking the count-on area on the touchscreen.

[0046] Step 102: After entering the counting state, acquire the ultrasound image to be counted until the counting cycle is completed.

[0047] It is understood that in this embodiment, after the ultrasound device starts the counting function, it can enter the counting state to obtain ultrasound images (i.e. ultrasound images to be counted) that need to be counted within the counting cycle, and perform follicle detection and counting on them to generate corresponding follicle count evaluation results.

[0048] Correspondingly, the specific method by which the ultrasound device enters the counting state after activating the counting function in this embodiment can be set by the designer according to the practical scenario and user needs. For example, the ultrasound device can directly enter the counting state after activating the counting function. To improve the accuracy of follicle counting and reduce the consumption of computing resources (after the counting function is activated, some ultrasound images acquired before the probe begins to move are recorded), the ultrasound device in this embodiment can further identify the operator's intention to enter the counting state according to the operator's actual needs. For example, the processor of the ultrasound device can determine whether the probe has moved after the counting function is activated based on the probe movement information of the ultrasound device; if it has moved, it enters the counting state. For example, the ultrasound device can use the sensor information collected by the motion sensor in the ultrasound device's probe and / or the image similarity of the real-time acquired ultrasound images to determine the probe movement information, thereby determining whether to enter the counting state. In other words, in this embodiment, entering the counting state by recognizing probe movement can also reduce the operator's sense of urgency, avoid having to immediately start moving the probe after activating the counting function, and improve the convenience of operation.

[0049] It should be noted that the specific method for determining whether the probe has moved based on the probe movement information of the ultrasound device can be set by the designer according to the practical scenario and user needs. For example, in some embodiments, when the ultrasound device uses sensor information collected by the motion sensor in the probe to determine the probe movement information, the ultrasound device can determine whether the probe has moved based on the sensor information collected by the motion sensor in the probe (a threshold can be set; when the sensor information indicating the probe's movement distance and / or speed exceeds a certain threshold, it is determined that the probe has moved, avoiding false judgments and improving user experience). If movement occurs, it enters a counting state; if no movement occurs, it can continue to acquire sensor information collected by the motion sensor. For example, the ultrasound device can determine whether the probe has moved based on the comparison between the probe movement distance indicated by the sensor information and a distance threshold and / or the comparison between the probe movement speed indicated by the sensor information and a speed threshold; for example, the ultrasound device can determine that the probe has moved and enter a counting state when the probe movement distance corresponding to the sensor information is greater than the distance threshold.

[0050] In other embodiments, the ultrasound device can determine whether the probe has moved based on the image similarity between the current frame ultrasound image acquired by the ultrasound device and the ultrasound image acquired when the counting function is activated (i.e., the ultrasound image of the counting function activation frame). If the probe has moved, it enters the counting state; if the probe has not moved, it can continue to acquire the current frame ultrasound image acquired by the ultrasound device. In other words, the probe movement information can be the image similarity between the current frame ultrasound image acquired by the ultrasound device in real time and the ultrasound image acquired when the counting function is activated (i.e., the ultrasound image of the counting function activation frame). For example, the ultrasound device can determine whether the image similarity between the current frame ultrasound image and the ultrasound image of the counting function activation frame is less than a similarity threshold; if so, it enters the counting state.

[0051] Specifically, the content of the ultrasound images to be counted in this step can be set by the designer according to the practical scenario and user needs. For example, the ultrasound images to be counted can be all image frames within the counting period of the ultrasound video received or stored by the ultrasound equipment, or a portion of image frames extracted from all image frames; the ultrasound images to be counted can also be all image frames or a portion of image frames (such as image frames extracted at intervals) in the ultrasound images acquired in real time by the ultrasound equipment within the counting period. This embodiment does not impose any restrictions on this.

[0052] Correspondingly, the specific cycle time setting for the counting period in this embodiment can be set by the designer according to the practical scenario and user needs. For example, the counting period can be determined by the running time after entering the counting state and / or the scanning distance of the probe. For instance, when the counting period is determined by the running time after the ultrasound device enters the counting state, the ultrasound device can determine that the counting period is complete when the running time after entering the counting state reaches a time threshold. To avoid the sense of time pressure brought to the operator of the ultrasound device when using time as the counting period measurement method, this embodiment can use scanning distance as the counting period measurement method, thereby making the operation process of the ultrasound device more user-friendly. That is, the counting period can be determined by the scanning distance of the probe. In other words, the ultrasound device can determine whether the counting period is complete based on the scanning distance of the probe after entering the counting state. For example, the ultrasound device can use the motion sensor in the probe or distance detection based on real-time ultrasound images to determine whether the scanning distance of the probe after entering the counting state has reached a distance threshold, and thus determine that the counting period is complete when the distance threshold is reached. When the counting cycle can be determined by the running time after entering the counting state and the scanning distance of the probe, the ultrasound equipment can determine that the counting cycle is completed when the scanning distance of the probe reaches the threshold after entering the counting state and the running time after entering the counting state reaches the time threshold.

[0053] Correspondingly, the counting period can also be determined by a triggered counting period end command. For example, the ultrasound device can determine whether the counting period is complete by judging whether a counting period end command has been triggered. For instance, after entering the counting state, the user can press the button switch on the ultrasound device's probe or toggle the switch on the probe to trigger the counting period end command and control the ultrasound device to end the counting period. Alternatively, after entering the counting state, the user can press the counting period end button on the keyboard or click the counting period end area displayed on the touch screen to trigger the counting period end command and control the ultrasound device to end the counting period.

[0054] Step 103: Perform follicle detection on each frame of ultrasound image to be counted to identify the number of follicles in each frame of ultrasound image to be counted.

[0055] Understandably, in this step, the processor of the ultrasound device can perform follicle detection on each frame of the ultrasound image to be counted, identify the follicles in each frame of the ultrasound image to be counted, and thus count the number of follicles in each frame of the ultrasound image to be counted.

[0056] Specifically, the specific method by which the processor performs follicle detection on each frame of ultrasound image to be counted in this step can be set by the designer according to the practical scenario and user needs. For example, the processor can adopt the same or similar method as the target detection and segmentation method in the prior art. As long as the processor can identify the follicles in each frame of ultrasound image to be counted, this embodiment does not impose any restrictions on this.

[0057] It should be noted that in this step, the ultrasound equipment can also identify the location of each follicle in each frame of the ultrasound image to be counted and output the follicle location information to the display of the ultrasound equipment so that the user can view the specific location of the follicle in the ultrasound image to be counted displayed on the display.

[0058] Correspondingly, the specific method for identifying the location of each follicle in each frame of ultrasound image to be counted can be set by the designer. For example, the processor can be implemented in the same or similar way as the target detection and segmentation method in the prior art. As long as the processor can identify the location of each follicle in each frame of ultrasound image to be counted, this embodiment does not impose any restrictions on this.

[0059] Specifically, the follicle location marking information used to identify the location of each follicle in the corresponding ultrasound image to be counted may include the follicle center point. That is, in this embodiment, the processor can mark the center point of each follicle to reduce the obstruction of the marking while indicating the location of the follicle area to the user; for example, the ultrasound device can control the display to mark the center point of each follicle with a cross mark. The follicle location marking information may also include the follicle area, that is, the processor can mark the follicle area of ​​each follicle; such as... Figure 2 As shown, the ultrasound equipment can control the display to mark the follicular regions of each follicle with outlines and crosshairs. Follicle location marking information may also include marker types such as boxes, outlines, and / or crosshairs to instruct the display to show each follicle in the ultrasound image to be counted with the corresponding marker type. Follicle location marking information may also include marker colors and / or serial numbers to help users distinguish different follicular regions; for example, the ultrasound equipment can control the display to mark the follicular regions of each follicle with different colored markers (such as boxes, outlines, and / or crosshairs).

[0060] It should be noted that, in real-time scenarios, optional implementation methods include performing follicle detection for each frame in real time and outputting the follicle position marking information for each frame to the display of the ultrasound device in real time; if computing power is insufficient, follicle detection can also be performed on all or part of the ultrasound image frames recorded within the counting cycle after the counting cycle ends, and then a unified follicle count evaluation can be performed.

[0061] Step 104: Generate follicle count assessment results based on the number of follicles in all ultrasound images to be counted.

[0062] It is understood that in this embodiment, the ultrasound device can generate follicle count assessment results based on the number of follicles in all ultrasound images to be counted within the counting cycle, making it convenient for users to understand the counting situation throughout the entire counting cycle.

[0063] Specifically, the content of the follicle counting assessment results in this step can be set by the designer. For example, the follicle counting assessment results can include the maximum count value, that is, the number of follicles in the image frame with the largest number of follicles in the counting cycle; the follicle assessment results can also include the maximum count frame, that is, the image frame with the largest number of follicles in the counting cycle; the follicle counting assessment results can also include the preferred count frame; wherein, the preferred count frame is the image frame in the queue of all ultrasound images to be counted whose corresponding section standard information is greater than the section standard threshold and whose number of follicles is sorted from largest to smallest and is at the top of the preset value.

[0064] In other words, in this embodiment, the ultrasound device can use evaluation models such as artificial neural networks to perform cross-sectional evaluation on each frame of the ultrasound image to be counted, obtaining the cross-sectional standardization information corresponding to each frame of the ultrasound image to be counted, thereby further improving the comprehensiveness and accuracy of the follicle counting evaluation results. Specifically, the preferred counting frame in the follicle evaluation results can be the image frame that meets the cross-sectional standardization threshold requirement (e.g., greater than the cross-sectional standardization threshold) and is among the top preset values ​​in the follicle count sorting queue from largest to smallest among all the ultrasound images to be counted. That is, the ultrasound images among the ultrasound images to be counted that meet the acceptable standard of cross-sectional evaluation and are among the top N (i.e., the preset value) in the follicle count sorting queue. The follicle evaluation results may also include the optimal counting frame, such as the image frame with the largest number of follicles among the preferred counting frames.

[0065] The follicle assessment results may also include sorting results, such as follicle number sorting results obtained by sorting the number of follicles and / or section standardization sorting results obtained by sorting the section standardization information of all the ultrasound images to be counted, thereby showing the comprehensive situation of the ultrasound images to be counted, such as displaying them by histogram, matrix diagram (such as confusion matrix), median, sorting according to standards such as follicle number or section standardization.

[0066] Correspondingly, the method provided in this embodiment may also include obtaining a video evaluation and display instruction; and displaying the corresponding content in the follicle count evaluation result according to the display control information of the video evaluation and display instruction.

[0067] In this embodiment, the present invention detects follicles in each frame of the ultrasound image to be counted, identifies the number of follicles in each frame, and can automatically identify the location of follicles in each frame of the video, thereby enabling statistical counting of follicles in each frame and realizing automatic counting of follicles in the video.
