[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The ultrasound image acquisition method provided in the present application can be executed by a computer device, including: Figure 1 The steps shown are:

[0050] Step S101, when entering the automatic section adjustment mode, controlling the acoustic head inside the intracavitary ultrasound probe to continuously rotate;

[0051] Reference Figure 2After turning on the automatic section adjustment mode, the motor can be used to control the sound head inside the intracavitary ultrasound probe to rotate continuously. The sound head is located inside the intracavitary ultrasound probe, and the rotation of the sound head will not affect the subject. During the rotation of the sound head, the shell of the intracavitary ultrasound probe that is in direct contact with the subject does not rotate, and the subject will not feel that there is a foreign object rotating in the body, and the discomfort is low.

[0052] Step S102: obtaining a first type of real-time ultrasonic image according to the real-time ultrasonic image during the continuous rotation of the acoustic head.

[0053] Real-time ultrasonic images can be collected during the continuous rotation of the acoustic head. To distinguish them from real-time ultrasonic images of other processes, the real-time ultrasonic images during the continuous rotation of the acoustic head are called the first type of real-time ultrasonic images.

[0054] Step S103, according to the image comparison result between the first type of real-time ultrasound image and the standard section, the standard section is determined and the rotation of the ultrasonic head is stopped.

[0055] During the continuous rotation of the acoustic head, each time the acoustic head rotates to a certain angle, the first type of real-time ultrasound image at the angle can be compared with the standard section to obtain an image comparison result corresponding to the angle.

[0056] According to the image comparison result corresponding to the angle, it is determined that the image content similarity between the first type of real-time ultrasound image and the standard section is greater than or equal to the threshold, which means that the observation section of the ultrasound head at this angle is the standard section; at this time, the ultrasound head can be directly controlled to stop rotating so that the ultrasound head is at this angle to obtain the standard section; or, the angle can be recorded, the ultrasound head can continue to rotate, and after the rotation of the ultrasound head is completed, the ultrasound head is controlled to rotate back to this angle to obtain the standard section.

[0057] According to the image comparison result corresponding to the angle, it is determined that the image content similarity between the first type of real-time ultrasound image and the standard section is lower than the threshold, which means that the section observed by the ultrasound head at this angle is a non-standard section, and the ultrasound head can be controlled to continue rotating until a standard section is obtained. The threshold value can be set according to actual conditions.

[0058] In the above-mentioned ultrasound image acquisition method, when entering the automatic section adjustment mode, the acoustic head inside the intracavitary ultrasound probe is controlled to rotate continuously, and a first type of real-time ultrasound image is obtained based on the real-time ultrasound image during the continuous rotation of the acoustic head. Based on the image comparison result between the first type of real-time ultrasound image and the standard section, the standard section is determined and the rotation of the acoustic head is stopped. The rotation of the acoustic head inside the intracavitary ultrasound probe will not affect the subject. Compared with the rotation of the intracavitary ultrasound probe as a whole, the discomfort of the subject can be reduced.

[0059] In one embodiment, the method provided in the present application also includes: obtaining a second type of real-time ultrasound image based on the real-time ultrasound image of the intracavitary ultrasound probe during the process of penetrating the cavity; determining whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position based on the second type of real-time ultrasound image; when the real-time position belongs to the target observation position, determining to enter the automatic section adjustment mode.

[0060] The intracavitary ultrasound probe can collect real-time ultrasound images during the process of penetrating deep into the cavity. For the purpose of distinction, the real-time ultrasound images collected during the process of penetrating deep into the cavity are referred to as second-category real-time ultrasound images.

[0061] The target observation position may include a position in the cavity that the user wants to observe. According to the content presented by the second type of real-time ultrasound image, it can be determined whether the real-time position of the intracavitary ultrasound probe during the process of penetrating into the cavity belongs to the target observation position. If the real-time position belongs to the target observation position, it can be determined to enter the automatic section adjustment mode.

[0062] This embodiment obtains a second type of real-time ultrasound image based on the real-time ultrasound image of the intracavitary ultrasound probe during the process of penetrating deep into the cavity, and determines whether the real-time position of the intracavitary ultrasound probe during the process of penetrating deep into the cavity belongs to the target observation position based on the second type of real-time ultrasound image; when the real-time position belongs to the target observation position, the automatic section adjustment mode is entered to alleviate the heating of the intracavitary ultrasound probe.

[0063] In one embodiment, determining whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position based on the second type of real-time ultrasound image includes: comparing the second type of real-time ultrasound image with the target ultrasound image of the target observation position to determine whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position.

[0064] Before the start of this intracavitary ultrasound examination, real-time ultrasound images collected by the intracavitary ultrasound probe during the process of penetrating the cavity can be obtained. The user (such as a doctor) can judge whether the real-time position of the intracavitary ultrasound probe is at the target observation position based on the content of the real-time ultrasound image during the process of penetrating the cavity. If so, the user can mark the real-time ultrasound image and use the marked real-time ultrasound image during the process of penetrating the cavity as the target ultrasound image collected by the intracavitary ultrasound probe at the target observation position.

[0065] In some scenarios, the feature vector of the second type of real-time ultrasound image (which may be called the first feature vector) and the feature vector of the target ultrasound image (which may be called the second feature vector) may be extracted through a pre-built feature extraction network, and the distance between the first feature vector and the second feature vector may be obtained, and the distance may be called the feature distance. According to the feature distance, the difference between the second type of real-time ultrasound image and the target ultrasound image may be obtained. The larger the feature distance, the greater the difference. The specific implementation method may be, for example:

[0066] Method 1: pre-set a linear function, such as y1=k1×x1, where x1 is the feature distance, k1 is the coefficient, y1 is the difference, k1 is known, k1 can be set to a positive number, and the specific size of k1 can be set according to actual conditions; after obtaining the feature distance according to the first eigenvector and the second eigenvector, the feature distance can be substituted into x1 to obtain the value of y1, and the value of y1 is used as the difference between the second type of real-time ultrasound image and the target ultrasound image.

[0067] Method 2: Preset multiple feature distance intervals, the highest feature distance interval corresponds to the largest difference, and the smallest feature distance interval corresponds to the smallest difference; after obtaining the feature distance according to the first feature vector and the second feature vector, it is possible to determine the feature distance interval to which the feature distance belongs, and use the difference corresponding to the feature distance interval as the difference between the second type of real-time ultrasound image and the target ultrasound image.

[0068] According to the difference between the second type of real-time ultrasound image and the target ultrasound image, it can be determined whether the real-time position of the intracavitary ultrasound probe during the process of penetrating into the cavity belongs to the target observation position. The smaller the difference, the greater the probability that the real-time position belongs to the target observation position. The specific implementation method can be, for example:

[0069] Method 1: Pre-set a linear function, such as y2=k2×x2, where x2 is the difference, k2 is the coefficient, y2 is the probability, k2 is known, k2 can be set to a negative number, and the specific size of k2 can be set according to actual conditions; after obtaining the difference between the second type of real-time ultrasound image and the target ultrasound image, the difference can be substituted into x2 to obtain the value of y2, and the value of y2 is used as the probability that the real-time position of the intracavitary ultrasound probe in the process of penetrating into the cavity belongs to the target observation position.

[0070] Method 2: Preset multiple difference intervals, the highest difference interval corresponds to the smallest probability, and the smallest difference interval corresponds to the largest probability; after obtaining the difference between the second type of real-time ultrasound image and the target ultrasound image, the difference interval to which the difference belongs can be determined, and the probability corresponding to the difference interval is used as the probability that the real-time position of the intracavitary ultrasound probe in the process of penetrating into the cavity belongs to the target observation position.

[0071] According to the probability that the real-time position of the intracavitary ultrasound probe belongs to the target observation position during the process of penetrating the cavity, when it is determined that the real-time position does not belong to the target observation position, the automatic section adjustment mode may not be entered, and the user is reminded to continue to push the intracavitary ultrasound probe deeper into the cavity.

[0072] According to the probability that the real-time position of the intracavitary ultrasound probe belongs to the target observation position during the process of deepening the cavity, when it is determined that the real-time position belongs to the target observation position, the user can be reminded to pause deepening and enter the automatic section adjustment mode.

[0073] This embodiment directly compares the second type of real-time ultrasound image with the target ultrasound image at the target observation position, and can determine whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position without the help of a position prediction network, thereby eliminating sample preparation and network parameter adjustment operations in the training phase and improving processing efficiency.

[0074] In one embodiment, determining whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position based on the second type of real-time ultrasound images includes: acquiring video samples; the video samples are collected during the process of the intracavitary ultrasound probe penetrating into the cavity within a historical period, and / or collected during the process of an intracavitary ultrasound probe other than the intracavitary ultrasound probe penetrating into the cavity within a historical period; obtaining a position prediction network based on target ultrasound image samples marked as target observation ultrasound positions and non-target ultrasound image samples marked as non-target observation ultrasound positions in the video samples; and inputting the second type of real-time ultrasound images into the position prediction network to determine whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position.

[0075] This embodiment determines whether the real-time position of the intracavitary ultrasound probe in the process of penetrating into the cavity belongs to the target observation position by means of the result output by the position prediction network. The input of the position prediction network includes the ultrasound image, and the output includes whether the position when the corresponding ultrasound image is collected belongs to the target observation position, or whether the position when the corresponding ultrasound image is collected does not belong to the target observation position.

[0076] Specifically, the training samples used to construct the location prediction network can be obtained in the following way:

[0077] The video collected by the intracavitary ultrasound probe of step S101 during the process of penetrating the cavity within the historical period can be obtained, and the video can be used as a video sample; the video collected by an intracavitary ultrasound probe other than the intracavitary ultrasound probe of step S101 during the process of penetrating the cavity within the historical period can also be obtained, and the video can be used as a video sample.

[0078] Each frame of ultrasound image in the video sample may be referred to as an ultrasound image sample. For each ultrasound image sample, the user may determine whether the position at which the ultrasound image sample is collected belongs to the target observation position according to the content of the ultrasound image sample.

[0079] If the position when the ultrasound image sample is collected belongs to the target observation position, the ultrasound image sample can be marked as the target observation position, and the ultrasound image sample can be called a target ultrasound image sample.

[0080] If the position at which the ultrasound image sample is collected does not belong to the target observation position, the ultrasound image sample may be marked as a non-target observation position, and the ultrasound image sample may be called a non-target ultrasound image sample.

[0081] A training sample is formed according to target ultrasound image samples marked as target observation positions and non-target ultrasound image samples marked as non-target observation positions, and training is performed based on the training samples to obtain a position prediction network.

[0082] After the position prediction network is obtained, the second type of real-time ultrasound image can be input into the position prediction network.

[0083] If the result output by the position prediction network is that the position when the second type of ultrasound image is acquired belongs to the target observation position, it can be determined that the real-time position of the intracavitary ultrasound probe during the process of penetrating into the cavity belongs to the target observation position.

[0084] If the result output by the position prediction network is that the position when the second type of ultrasound image is acquired does not belong to the target observation position, it can be determined that the real-time position of the intracavitary ultrasound probe during the process of penetrating into the cavity does not belong to the target observation position.

[0085] This embodiment uses a position prediction network to analyze and process the second type of real-time ultrasound images, and can automatically determine whether the real-time position of the intracavitary ultrasound probe in the process of penetrating into the cavity belongs to the target observation position, and ensure the accuracy of position recognition.

[0086] In one embodiment, the second type of real-time ultrasound image is input into the position prediction network, including Figure 3 The steps shown are: step S301, obtaining the real-time penetration distance of the intracavitary ultrasound probe during the process of penetrating into the cavity; step S302, if the real-time penetration distance is greater than or equal to the minimum observable distance, inputting the second type of real-time ultrasound image into the position prediction network; the minimum observable distance is the minimum penetration distance at which the target organ can be observed.

[0087] The minimum penetration distance at which the target organ can be observed. For example, when the cavity is the vagina, the target organ that the user wants to observe is the ovary. Generally speaking, when the distance that the intracavitary ultrasound probe penetrates into the vagina is greater than or equal to a certain distance, the ultrasound image collected by the intracavitary ultrasound probe is more likely to include the ovary. When the distance that the intracavitary ultrasound probe penetrates into the vagina is less than the distance, the ultrasound image collected by the intracavitary ultrasound probe basically does not include the ovary. This distance is the minimum penetration distance at which the ovary can be observed.

[0088] The minimum depth at which the target organ can be observed is taken as the minimum observable distance. The minimum observable distance varies depending on the target organ.

[0089] After obtaining the second type of real-time ultrasound image, the real-time penetration distance of the intracavitary ultrasound probe into the vagina can be obtained, and this distance is called the real-time penetration distance.

[0090] If the real-time depth distance is less than the minimum observable distance, it means that the second type of real-time ultrasound image basically does not contain the target organ, reflecting that the intracavitary ultrasound probe is far away from the target observation position. At this time, the second type of real-time ultrasound image can be omitted from the position prediction network for prediction, saving computing resources.

[0091] If the real-time depth distance is greater than or equal to the minimum observable distance, it means that the second type of real-time ultrasound image is more likely to contain the target organ, reflecting that the intracavitary ultrasound probe is relatively close to the target observation position. At this time, the second type of real-time ultrasound image can be input into the position prediction network for prediction to determine whether the real-time position of the intracavitary ultrasound probe belongs to the target observation position.

[0092] In one embodiment, the real-time penetration distance of the intracavitary ultrasound probe during its penetration into the cavity is obtained, including: obtaining the real-time penetration speed of the intracavitary ultrasound probe during its penetration into the cavity based on the Doppler effect of ultrasound; and obtaining the real-time penetration distance of the intracavitary ultrasound probe based on the real-time penetration speed and the penetration time of the intracavitary ultrasound probe.

[0093] When the intracavitary ultrasonic probe penetrates deeply into the cavity, the real-time penetration speed of the intracavitary ultrasonic probe can be obtained according to the Doppler effect of ultrasound, and the real-time penetration distance of the intracavitary ultrasonic probe can be obtained according to the product of the real-time penetration speed and the penetration time of the intracavitary ultrasonic probe.

[0094] In one embodiment, obtaining a real-time ultrasonic image of an intracavitary ultrasonic probe during its deep penetration into a cavity comprises: determining a real-time value of a transmission parameter according to the real-time penetration distance of the intracavitary ultrasonic probe during its deep penetration into the cavity; the deeper the real-time penetration distance, the higher the performance corresponding to the real-time value of the transmission parameter; and controlling the intracavitary ultrasonic probe to transmit ultrasonic waves according to the real-time value of the transmission parameter to acquire a real-time ultrasonic image of the intracavitary ultrasonic probe during its deep penetration into the cavity.

[0095] The transmission parameters of this embodiment mainly include transmission parameters that affect the heating of the intracavity ultrasound probe. Such transmission parameters include at least one of the line density of the intracavity ultrasound probe and the analog signal sampling rate.

[0096] The higher the performance corresponding to the value of this type of transmission parameter, the more heat the intracavitary ultrasound probe generates. For example, the larger the value of the line density, the higher the performance and the more heat is generated. For another example, the larger the value of the analog signal sampling rate, the higher the performance and the more heat is generated.

[0097] When the transmission parameter includes line density, the real-time value of the transmission parameter includes the real-time value of the line density of the intracavitary ultrasound probe; when the transmission parameter includes the analog signal sampling rate, the real-time value of the transmission parameter includes the real-time value of the analog signal sampling rate of the intracavitary ultrasound probe.

[0098] In order to further alleviate the heating of the intracavitary ultrasound probe, the real-time penetration distance of the intracavitary ultrasound probe can be obtained during the process of the intracavitary ultrasound probe penetrating into the cavity. The real-time value of the transmission parameter is determined according to the real-time penetration distance. The deeper the real-time penetration distance, the higher the image quality corresponding to the real-time value of the transmission parameter. For example, the deeper the real-time penetration distance, the larger the real-time value of the line density can be set, and the higher the image quality. For another example, the deeper the real-time penetration distance, the larger the real-time value of the analog signal sampling rate can be set, and the higher the image quality.

[0099] According to the real-time value of the transmission parameter, the intracavitary ultrasonic probe is controlled to transmit ultrasonic waves to collect real-time ultrasonic images of the intracavitary ultrasonic probe during its deep penetration into the cavity.

[0100] In one embodiment, obtaining a real-time ultrasonic image during the process of an intracavitary ultrasonic probe penetrating deeply into a cavity comprises: during the process of the intracavitary ultrasonic probe penetrating deeply into the cavity, determining whether the real-time penetration distance of the intracavitary ultrasonic probe is greater than or equal to a distance threshold; if the real-time penetration distance is greater than or equal to the distance threshold, obtaining the real-time value of the transmission parameter according to a first set of transmission parameter values; if the real-time penetration distance is less than the distance threshold, obtaining the real-time value of the transmission parameter according to a second set of transmission parameter values; the image quality corresponding to the first set of transmission parameter values ​​is higher than that of the second set of transmission parameter values; and according to the real-time value of the transmission parameter, controlling the intracavitary ultrasonic probe to transmit ultrasonic waves to collect the real-time ultrasonic image during the process of penetrating deeply into the cavity.

[0101] The transmission parameters of this embodiment mainly include transmission parameters that affect the heating of the intracavity ultrasound probe. Such transmission parameters include at least one of the line density of the intracavity ultrasound probe and the analog signal sampling rate.

[0102] The distance threshold can be set to the aforementioned minimum observable distance. Take the minimum observable distance as an example:

[0103] In the process of the intracavitary ultrasound probe penetrating into the cavity, it can be determined whether the real-time penetration distance of the intracavitary ultrasound probe is greater than or equal to the minimum observable distance. If the real-time penetration distance is greater than or equal to the minimum observable distance, it means that the second-class real-time ultrasound image is more likely to contain the target organ, reflecting that the intracavitary ultrasound probe is relatively close to the target observation position. At this time, the first set of emission parameter values ​​with high image quality can be used as the real-time value of the emission parameter to collect the second-class real-time ultrasound image with better image quality. If the real-time penetration distance is less than the minimum observable distance, it means that the second-class real-time ultrasound image basically does not contain the target organ, reflecting that the intracavitary ultrasound probe is far away from the target observation position. At this time, the second set of emission parameter values ​​with low image quality can be used as the real-time value of the emission parameter to collect the second-class real-time ultrasound image with general image quality to alleviate the fever.

[0104] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0105] Based on the same inventive concept, the embodiment of the present application also provides an ultrasonic image acquisition device for implementing the ultrasonic image acquisition method involved above. The implementation solution provided by the device to solve the problem is similar to the implementation solution recorded in the above method, so the specific limitations in one or more ultrasonic image acquisition device embodiments provided below can refer to the limitations of the ultrasonic image acquisition method above, and will not be repeated here.
