Description

TECHNICAL FIELD

[0002] With the continuous development of ultrasonic equipment technology, a standard section automatic acquisition function appears in the process of ultrasonic detection. This function can automatically identify and capture standard section images of each ultrasonic section when the operator performs ultrasonic scanning, such as thalamic transverse section, nasolabial coronal section, etc. Among them, the automatic capture process generally performs algorithm model reasoning on each acquired ultrasonic section image to obtain a corresponding section score, which represents the standard degree of the section. When the section score is greater than the threshold, the corresponding section image is captured as a standard section image.

[0003] In related technologies, the threshold of the standard section automatic acquisition function generally uses a default threshold. However, in different medical staff usage, the threshold for judging the standard section has different requirements. For example, due to the different operation years, qualifications, fetal positions, and picture taking techniques of doctors, when performing scoring prediction of ultrasonic sections, senior doctors think that more than 80 points is standard; middle-aged doctors think that more than 75 points is standard; and junior doctors think that more than 70 points is standard. Since the threshold of the standard section automatic acquisition function generally uses a default threshold, if the doctor is not satisfied with the current threshold and needs to modify it, it will be relatively complex, resulting in low efficiency, and it is also difficult to achieve personalized threshold setting requirements, thereby resulting in poor user experience.

[0062] The core of the present application is to provide a threshold setting method of an ultrasound standard section, a threshold setting device, an ultrasound device and a computer readable storage medium, and to improve the efficiency of threshold setting.

[0063] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0064] In the related art, the threshold of the standard section automatic acquisition function is generally a default threshold. However, the threshold for standard section judgment has different requirements in different medical staff use cases. For example, due to the different operation years, qualifications of doctors, fetal positions, and picture taking techniques, when performing ultrasound section score prediction, senior doctors consider that 80 points or more is standard; middle-aged doctors consider that 75 points or more is standard; and low senior doctors consider that 70 points or more is standard. Since the threshold of the standard section automatic acquisition function currently generally uses a default threshold and is embedded in the algorithm code, if the doctor user is not satisfied with the current threshold and needs to modify it, it will be relatively complex, resulting in low efficiency, making it difficult to achieve personalized threshold setting requirements, and further resulting in poor user experience.

[0065] Therefore, the present application provides an ultrasound section threshold setting method, which acquires section materials, then calculates the standard degree of the section materials based on a standard section recognition algorithm to determine a reference standard value, and further sets a standard threshold based on the reference standard value, which can realize personalized setting of the ultrasound section threshold, improve the setting efficiency of the threshold, meet diversified use scenarios, and thus help improve user experience.

[0066] The following describes an ultrasound section threshold setting method provided by the present application through an embodiment.

[0067] Please refer to Figure 1 , Figure 1 The flowchart of the first ultrasound section threshold setting method provided by the present application embodiment.

[0068] In this embodiment, the method can include:

[0069] S11, acquiring section materials selected by a user; wherein the section materials include standard section ultrasound videos or critical standard ultrasound section images;

[0070] It can be seen that this step aims to acquire section materials selected by a user. It can be to enter a manual operation picture screening process (i.e., an ultrasound scanning process in which a user uses an ultrasound probe to detect a human body part), in which the section materials selected by the user are acquired. Alternatively, the user can import section materials after screening. The section materials include standard section ultrasound videos or critical standard ultrasound section images. It should be noted that the standard section ultrasound video selected by the user refers to an ultrasound video in which each frame of section image reaches or is above the standard recognized by the user, and the critical standard ultrasound section image selected by the user refers to a section image that just reaches the standard recognized by the user. In addition, the user of this embodiment can be a user who needs to adjust the standard threshold of the ultrasound section image.

[0071] In actual operation, the user can first enter the threshold automatic acquisition function interface, and after entering, the user can use the ultrasonic probe to perform ultrasonic scanning on the human body part. During the scanning process, the user can manually confirm the standard degree of the generated ultrasonic section image. The user considers that the ultrasonic section image or the standard section ultrasonic video belongs to the above-mentioned critical standard ultrasonic section image, and then stores it. Therefore, the stored critical standard ultrasonic section image and the standard section ultrasonic video can be applied to the present embodiment to realize automatic matching and setting of the threshold.

[0072] It can be seen that the selected section material is actually the content selected by the operator, which represents the standard requirement of the operator for the section.

[0073] S12, performing standard degree calculation on the section material based on a standard section recognition algorithm to obtain a reference standard value; wherein the standard section recognition algorithm is used to identify the standard section image according to the standard threshold;

[0074] On the basis of S11, a standard degree calculation is performed on the section material based on a standard section recognition algorithm to obtain a reference standard value; wherein the standard section recognition algorithm is used to identify the standard section image according to the standard threshold. That is, the standard degree of the selected section material is inferred and predicted by using the standard section recognition algorithm, and the standard value of the standard degree of the critical standard ultrasound section image or the standard degree of each ultrasound section image of the standard section ultrasound video is determined, that is, the reference standard value, and then the reference standard value can be used to realize the personalized automatic matching of the standard threshold in the subsequent, that is, for different users, the selected section material will be different for the same section, and the standard degree identified by the user will be different, and the reference standard value calculated for different users will also be different, and thus the reference standard value calculated can be used to match the standard threshold corresponding to the different user needs, and the threshold is personalized. The reference standard value can be presented in the form of a section score; specifically, the standard section recognition algorithm can use classification confidence and the like to calculate and obtain the reference standard value when calculating the reference standard value of the related section image. The standard section recognition algorithm can use machine learning recognition algorithms, including but not limited to neural network algorithms, such as RetinaNet, YOLO series, RCNN series, and the like. The ultrasound device can use the standard section recognition model algorithm to identify the section type from the above-mentioned section material, and can calculate and infer or predict the section score reflecting the standard degree of the section, and then the section score and the standard threshold can be compared, and the ultrasound device will determine that the ultrasound section image with a section score greater than the standard threshold belongs to the standard section image. Since the obtained section material is a picture or image about the section, any section material can be calculated by the standard section recognition algorithm to obtain a standard value or multiple standard values.

[0075] If the section material is a critical standard ultrasound section image, the standard section recognition algorithm can be used to directly infer and calculate the critical standard ultrasound section image to obtain the reference standard value.

[0076] If the section material is a standard section ultrasound video, the standard section recognition algorithm is used to infer and calculate each image in the standard section ultrasound video to obtain multiple reference standard values, and then the standard threshold is set based on the multiple reference standard values.

[0077] In order to set a corresponding standard threshold for each section type and improve the practicability and reliability of the automatic threshold setting, S12 and S13 in the embodiment can include:

[0078] S121, performing standard degree calculation on the section material corresponding to each section type based on the standard section recognition algorithm to obtain the reference standard value corresponding to each section type;

[0079] S122, setting the standard threshold of the corresponding section type according to the reference standard value corresponding to each section type.

[0080] It can be seen that in this optional solution, how to process the section images of each section type is mainly explained. First, based on the standard section recognition algorithm, the section classification of the section material can be realized, and the standard degree calculation can be performed on the section material corresponding to each section type to obtain the reference standard value corresponding to each section type. That is, the obtained section material can include one or more types of ultrasonic section images of the section type, so that in the process of the embodiment, the corresponding reference standard value of each section type of the section image is obtained. Then, the standard threshold of the corresponding section type is set according to the reference standard value corresponding to each section type. Obviously, this helps to improve the setting efficiency.

[0081] S13, setting the standard threshold according to the reference standard value.

[0082] On the basis of S12, the purpose of this step is to set the standard threshold according to the reference standard value. That is, the reference standard value is used to set the threshold (i.e. the standard threshold) in the standard section automatic acquisition function, wherein the standard section recognition algorithm used for identifying the ultrasonic image in the standard section automatic acquisition function and the standard section recognition algorithm used for standard degree calculation in the threshold automatic acquisition function can use the same or basically the same algorithm. After completing the setting of the standard threshold, the standard section automatic acquisition function can be executed based on the standard threshold. In this way, the ultrasonic device can automatically match and set the standard threshold based on the user-selected section material, without the need for manual setting, thereby improving the threshold setting efficiency.

[0083] When the section material is a critical standard ultrasonic section image, in order to improve the accuracy and reliability of setting the standard threshold, this step can include:

[0084] S131, judging whether the reference standard value is greater than the conventional threshold;

[0085] S132, if yes, the reference standard value is taken as the standard threshold;

[0086] S133, if no, the conventional threshold is taken as the standard threshold.

[0087] It can be seen that in the optional solution, how to process under the critical standard ultrasound section image is mainly explained. In the optional solution, first, the standard degree of the critical standard ultrasound section image is calculated based on the standard section recognition algorithm to obtain a reference standard value. Then, it is judged whether the reference standard value of the corresponding section type is greater than the corresponding conventional threshold value; if yes, the reference standard value is taken as the standard threshold value; if no, the conventional threshold value is taken as the standard threshold value. Since the standard section recognition algorithm can judge whether the recognized ultrasound section image belongs to the standard section based on the standard threshold value, and can also calculate the reference standard value reflecting the standard degree (which can be presented by the section score), for the case that the reference standard value is greater than the conventional threshold value, the reference standard value corresponding to the user's demand is taken as the standard threshold value, so that the personalized automatic matching of the standard threshold value can be realized, and when the reference standard value is less than the conventional threshold value, the reliability of the standard section recognition can be ensured by taking the conventional threshold value as the standard threshold value, that is, the standard degree of the recognized standard section can finally be maintained at least at the general standard or above.

[0088] The conventional threshold value is a general standard threshold value set in the ultrasound equipment for each section type, and the conventional threshold value corresponding to each section type can be different. The conventional threshold value usually needs to be obtained through a large number of experiments by doctors of various seniority, and is usually the average threshold value of doctors of various seniority. If the standard threshold value is only set to the conventional threshold value, when a doctor of high seniority uses it, it may be considered that the entry condition is too low, and the ultrasound section image considered by the doctor as a non-standard section image is also recognized as a standard section image, and when a doctor of low seniority uses it, it may be considered that the entry condition is too high, and thus the ultrasound equipment is considered to not recognize a standard section image. Therefore, by realizing the above personalized automatic matching and setting of the standard threshold value, the demand of the user for the personalized setting of the threshold value can be met, and the user experience can be improved and the work efficiency can be optimized.

[0089] Of course, in one of the embodiments, the reference standard value calculated based on the critical standard ultrasound section image can be directly taken as the standard threshold value without comparison with the conventional threshold value.

[0090] When the section material is a standard section ultrasound video, in order to improve the accuracy and reliability of the threshold setting, the step can include:

[0091] S134, the standard degree of each frame image of the standard section ultrasound video is calculated based on the standard section recognition algorithm to obtain a plurality of reference standard values;

[0092] S135, the plurality of reference standard values are arranged according to the size relationship, and the reference standard value of the preset proportion division point is taken as a target standard value, that is, a division standard value;

[0093] S136, it is judged whether the division standard value is greater than the conventional threshold value;

[0094] S137, if yes, the demarcation standard value is taken as the standard threshold value;

[0095] S138, if no, the regular threshold value is taken as the standard threshold value.

[0096] It can be seen that in the optional solution, how to process under the standard section ultrasound video is mainly explained. The standard degree of each frame section image of the standard section ultrasound video is calculated based on the standard section recognition algorithm to obtain a plurality of reference standard values. The plurality of reference standard values are arranged according to the size relationship, and the reference standard value of the preset percentage demarcation point is taken as the demarcation standard value. That is, a suitable standard value is selected from each frame image of the section ultrasound video as the demarcation standard value. The preset percentage point can be 5%, 10%, 20%, etc., and can be set based on actual application. Finally, it is judged whether the demarcation standard value is greater than the regular threshold value; if yes, the demarcation standard value is taken as the standard threshold value; if no, the regular threshold value is taken as the standard threshold value. By comparing the demarcation standard value with the regular threshold value, the standard threshold value can be determined. Since the demarcation standard value is derived from the above-mentioned reference standard values, the standard degree of the recognized standard section can be at least maintained at the general standard or above the general standard while achieving personalized automatic matching of the standard threshold value. Therefore, it is also beneficial to improve user experience, optimize work efficiency, and ensure the accuracy and reliability of standard section recognition.

[0097] In the above-mentioned embodiments, after calculating the reference standard value of each frame image of the standard section ultrasound video, the demarcation standard value is determined from the plurality of reference standard values as the target standard value. However, the application does not limit the way of obtaining the target standard value from the plurality of reference standard values. In addition to the above-mentioned demarcation standard value as the target standard value, the target standard value can also be determined in other ways, such as linear or nonlinear processing of the plurality of reference standard values, and then determining the reasonable range to determine the target standard value. In addition, after determining the target standard value, in addition to the result of comparing the target standard value with the regular threshold value to set the standard threshold value, in other embodiments, the obtained target standard value can also be directly taken as the standard threshold value as needed.

[0098] After the reference standard value is matched to the standard threshold value, the standard section recognition algorithm can automatically recognize the standard section image using the newly set standard threshold value. In actual operation, the automatic matching setting of the standard threshold value can be performed under the threshold value automatic acquisition function. After completing the automatic matching setting of the standard threshold value, the threshold value automatic acquisition function can be exited and the standard section intelligent function (i.e. the above-mentioned standard section automatic acquisition function) can be entered. Actual ultrasound scanning can be performed to realize automatic recognition and acquisition of the standard section image and automatic measurement. The measurement result can be automatically displayed on the display interface.

[0099] Further, in one embodiment, setting the standard threshold value according to the reference standard value can include: obtaining a second threshold parameter set by the user based on the reference standard value; and setting the standard threshold value according to the second threshold parameter.

[0100] The reference standard value can be the corresponding reference standard value in the above embodiments. The second threshold parameter can be a target threshold value input by the user after observing the displayed reference standard value and the standard degree of the section material seen by the user, and the target threshold value can be used as the standard threshold value to complete the setting of the standard threshold value. That is, the target threshold value is a value input by the user in combination with the reference standard value calculated by the standard section recognition algorithm and the judgment of the standard degree of the section material by the user. In actual operation, the online threshold setting function can be entered first, and then the user can use the ultrasonic probe to perform ultrasonic scanning under the function to obtain relevant ultrasonic section images. During or after the scanning, when it is observed that the scanned or saved ultrasonic section image is a critical standard section image, the section score (i.e., the reference standard value) of the corresponding ultrasonic section image calculated by the standard section recognition algorithm is also observed, and then the second threshold parameter can be manually input as a target threshold value in combination with the standard degree calculated by the standard section recognition algorithm and the standard degree judged by the user, and the second threshold parameter is set as the standard threshold value by the ultrasonic device. Of course, the second threshold parameter can also be a linear or nonlinear adjustment parameter, and the ultrasonic device can adjust or set the standard threshold value based on a preset mode (such as a preset formula) using the linear or nonlinear parameter.

[0101] The embodiment can further include:

[0102] The standard threshold value is displayed for the user to confirm.

[0103] It can be seen that the optional solution mainly illustrates that the standard threshold value is displayed for the user to confirm, so as to avoid the problem of threshold value setting deviation.

[0104] The embodiment can further include:

[0105] The standard threshold value is reset based on the first threshold parameter manually input by the user.

[0106] It can be seen that the user can also manually input the first threshold parameter for adjustment or fine adjustment in the optional solution, which can further improve the setting efficiency of the threshold value and improve the reliability of the threshold value setting. Similar to the above method of setting the standard threshold value using the second threshold parameter, when the first threshold parameter is used to adjust the standard threshold value, the first threshold parameter can be directly used as the standard threshold value, or the first threshold parameter can be linearly transformed or nonlinearly transformed to obtain the standard threshold value.

[0107] In summary, this embodiment acquires the section material selected by the user, then calculates the standard degree of the section material based on the standard section algorithm to determine the reference standard value, and further sets the standard threshold based on the reference standard value. That is, the ultrasound device can directly and automatically match and set the standard threshold of the corresponding section based on the ultrasound material selected by the user. In addition, the user can also modify the standard threshold online based on the reference standard value, thereby realizing personalized matching and setting of the standard threshold, which is conducive to improving the user's work efficiency and enhancing the user experience.

[0108] The following specific embodiment further illustrates the online threshold setting method for ultrasonic standard sections provided in this application.

[0109] Please refer to Figure 2 , Figure 2 A flowchart illustrating a second method for setting the threshold of a standard ultrasonic section, as provided in an embodiment of this application.

[0110] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the interface for the second threshold setting method of the ultrasonic standard section provided in the embodiments of this application.

[0111] Please refer to Figure 4 , Figure 4 This is a schematic diagram illustrating the threshold confirmation of the second ultrasonic section threshold setting method provided in the embodiments of this application.

[0112] Depend on Figure 2 As can be seen, in this embodiment, the main use case for the online threshold setting function is for doctors to adjust the threshold in real time during the scanning process.

[0113] First, the doctor accesses the online threshold setting function and performs an ultrasound scan, which involves using an ultrasound probe to scan a part of the body to obtain ultrasound cross-sectional images. Under this function, the doctor can, during the scan, […]. Figure 3 The interface displays the section score (i.e., reference standard value) of each frame of ultrasound section image calculated by the standard section recognition algorithm; see the corresponding reference. Figure 3 The "algorithm prediction score" in the text refers to the section score, which doctors can then use to infer the section type based on the standard section recognition algorithm (see also: [link to relevant information]). Figure 3 The algorithm comprehensively judges the "predicted category" and the seen ultrasound cross-sectional image, and then... Figure 4The operation interface of the ultrasound device can be used to set or modify the online standard threshold value. For example, when the doctor scans the nasolabial coronal section, based on his own judgment, when he sees that the standard degree of the ultrasound section image of this section type has just changed from a non-standard section to a basically standard section (i.e., a critical standard section image of the nasolabial coronal section appears), the doctor checks the section score of the current ultrasound section recorded by the ultrasound device, and then adjusts the standard threshold value based on the section score and in combination with the standard condition of the critical standard section image of the nasolabial coronal section. The online adjustment can be direct manual input of the threshold value. For sections that are not adjusted, the standard threshold value remains set to the conventional threshold value or the threshold value set previously. In addition, the standard threshold value can be obtained by transformation using a reference standard value. For example, a linear transformation method can be used, i.e., standard threshold value = alph*reference standard value + beta, where alph is 1 by default and beta is 0. Of course, a nonlinear transformation can also be used to obtain the standard threshold value. When the standard threshold values of the ultrasound sections are set or adjusted, the doctor can click the section confirmation button, and then the ultrasound device automatically updates the standard threshold values of the ultrasound sections. Finally, the online threshold value setting function can be exited, and the standard section automatic acquisition function can be reentered to perform normal actual ultrasound scanning, realize automatic recognition and extraction of the standard section image, and automatically calculate and mark the measurement result on the display interface for the standard section image with a measurement item.

[0114] Please refer to Figure 5 , Figure 5 The flowchart of the third threshold value setting method of the ultrasound section provided in the embodiments of the present application.

[0115] Please refer to Figure 6 , Figure 6 The algorithm flowchart of the third threshold value setting method of the ultrasound section provided in the embodiments of the present application.

[0116] Please refer to Figure 7 , Figure 7 The interface schematic diagram of the third threshold value setting method of the ultrasound section provided in the embodiments of the present application.

[0117] Please refer to Figure 8 , Figure 8 The operation interface schematic diagram of the third threshold value setting method of the ultrasound section provided in the embodiments of the present application.

[0118] On the basis of Figure 5 , in the embodiments, the doctor enters the threshold value automatic acquisition function (i.e., the threshold value automatic acquisition system shown in the figure); in this function, the doctor performs normal ultrasound scanning, and in the scanning process, a frame of ultrasound image in which each ultrasound section just reaches a basically standard section (i.e., a critical standard ultrasound section image) can be saved, or an ultrasound video in which each ultrasound section reaches a basically standard section or above (i.e., a standard section ultrasound video) can be saved.

[0119] For the ultrasound device, when the critical standard ultrasound section image is retained, the section score (i.e. the reference standard value) of the critical standard ultrasound section image of each section type can be calculated by using the standard section recognition algorithm, and then the ultrasound device can set the standard threshold of each corresponding ultrasound section by using the section score of the critical standard ultrasound section image corresponding to each ultrasound section as the target standard value according to the Figure 6 algorithm. Specifically, after the section score of the critical standard ultrasound section image is calculated, the section score is taken as the target standard value, and it is determined whether the target standard value is greater than the conventional threshold of the ultrasound section corresponding to the critical standard ultrasound section image. If yes, the section score (i.e. the target standard value) of the critical standard ultrasound section image is taken as the standard threshold of the corresponding ultrasound section. If no, the conventional threshold is still taken as the standard threshold of the corresponding ultrasound section.

[0120] When the standard section ultrasound video is retained, the section score of each ultrasound section image of the ultrasound video is inferred by using the standard section recognition algorithm, and the section scores are arranged from small to large. The 5% demarcation point value is taken as the demarcation standard value, and the standard threshold of each ultrasound section is automatically set by the ultrasound device by using the Figure 6 algorithm. Specifically, after the demarcation standard value is obtained, the demarcation standard value is taken as the target standard value, and it is determined whether the target standard value is greater than the conventional threshold. If yes, the target standard value (i.e. the demarcation standard value) is set as the standard threshold of the corresponding ultrasound section type. If no, the conventional threshold is still set as the standard threshold of the corresponding ultrasound section. Finally, the ultrasound device automatically updates the standard threshold of each ultrasound section. At this time, the threshold automatic acquisition function can be exited, and the standard section automatic acquisition function is entered to perform normal ultrasound scanning and automatically recognize and acquire ultrasound section images.

[0121] In the specific operation process of the doctor, before the doctor enters the standard section automatic acquisition function, if the doctor wants to adjust the standard threshold, the doctor can first enter the threshold automatic acquisition function. After entering the function, the setting interface shown in Figure 7 is presented. Among them, Figure 7 The left part of the middle part is to show the section type to be processed, the middle part is to display the ultrasound image in the scanning process, and the right part is the clipboard area of the critical standard ultrasound section image or the standard section ultrasound video currently stored. The doctor scans the image while storing the critical standard ultrasound section image or the standard section ultrasound video just entered into the group, and the Figure 8The corresponding section type is selected in the operation interface to confirm the section. After all the sections are completely confirmed, the system automatically calculates and sets the standard threshold value of each ultrasound section according to the stored image of the doctor; after the automatic setting of the standard threshold value is completed, the threshold automatic acquisition function can be exited, at which time the doctor can enter the standard section automatic acquisition function or mode to perform normal actual ultrasound scanning operation, and realize automatic identification and extraction of the ultrasound standard section image.

[0122] It can be seen that, in the embodiment, the section material is acquired in the scanning flow, the standard degree of the section material is calculated based on the standard section identification algorithm, the reference standard value is obtained, and further, the standard threshold value can be personalized matched and set based on the reference standard value, which is beneficial to improve the efficiency of threshold setting and improve the user experience.
