Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic imaging, and in particular to an ultrasonic imaging system and a method for measuring ultrasonic images. Background Art

[0002] Ultrasound examination, especially obstetric ultrasound examination, usually requires scanning many standard sections, and checking the main anatomical structures and related functions from the obtained section images. The doctor judges whether the main anatomical structures and functions are normal through the obtained ultrasound section images, and records the examination results in the ultrasound report. Since there are many anatomical structures that need to be examined and recorded, relying on the doctor's experience to interpret and record ultrasound section images is inefficient, and it is easy to miss something, which may lead to incomplete examination reports and even missed diagnoses.

[0003] For example, in obstetric examinations, doctors usually need to identify anatomical structures in standard sections and measure them. Different anatomical structures have different measurement requirements (for example, some target parts need to be magnified for measurement). Doctors need to use corresponding measurement strategies according to different anatomical structures to obtain more accurate measurement data. Due to the large number of sections and measurement items, doctors often need to perform multiple operations, which affects work efficiency. Summary of the invention

[0004] The main purpose of the embodiments of the present application is to provide an ultrasound imaging system and an ultrasound image measurement method, aiming to efficiently and accurately assist users in completing the measurement of target anatomical structures in ultrasound images.

[0015] The control display shows the measurement results of the target anatomical structure.

[0016] It can be seen from the above embodiments that the ultrasound imaging system provided by the present application can complete the identification, magnification and measurement of the target anatomical structure in the target ultrasound image, and improve the measurement accuracy and reduce the operation complexity by magnifying the image to an appropriate multiple before measuring; and based on the received ultrasound measurement instructions, it can automatically perform the above-mentioned identification, magnification, measurement and other related actions with one click, thereby accurately and efficiently assisting users to obtain the measurement results of the target anatomical structure corresponding to the target ultrasound image.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0032] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0033] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] See also Figure 1 , Figure 1 An ultrasound imaging system according to an embodiment of the present invention is described. Figure 1 A schematic structural block diagram of an ultrasound imaging system according to an embodiment of the present invention is shown.

[0035] like Figure 1 As shown, the ultrasound imaging system 100 includes an ultrasound probe 110, a transmitting circuit 112, a receiving circuit 114, a processor 116, and a display 118. Further, the ultrasound imaging system may also include a transmit / receive selection switch 120 and a beamforming module 122, and the transmitting circuit 112 and the receiving circuit 114 may be connected to the ultrasound probe 110 through the transmit / receive selection switch 120.

[0036] The ultrasound probe 110 includes a plurality of transducer array elements, referred to as array elements, which may be arranged in a row to form a linear array, or arranged in a two-dimensional matrix to form a surface array, or may form a convex array. For example, a plurality of transducer array elements may be arranged in a single row along a preset direction, or a plurality of transducer array elements may be arranged in multiple rows along a preset direction.

[0037] The transducer array element is used to transmit ultrasonic waves according to the excitation electrical signal, or to convert the received ultrasonic waves into electrical signals. Therefore, each transducer array element can be used to realize the mutual conversion between the electrical pulse signal and the ultrasonic wave, so as to transmit the ultrasonic wave to the tissue corresponding to the scanning target, and can also be used to receive the ultrasonic wave echo reflected by the tissue. When performing ultrasonic examination, the transmission sequence and the reception sequence can be used to control which transducer array elements are used to transmit ultrasonic waves and which transducer array elements are used to receive ultrasonic waves, or control the transducer array elements to transmit ultrasonic waves or receive ultrasonic wave echoes in time slots. The transducer array elements involved in ultrasonic wave transmission can be excited by electrical signals at the same time, so as to transmit ultrasonic waves at the same time; or, the transducer array elements involved in ultrasonic wave beam transmission can also be excited by several electrical signals with a certain time interval, so as to continuously transmit ultrasonic waves with a certain time interval.

[0038] During the ultrasonic imaging process, the processor 116 controls the transmitting circuit 112 to send the delayed focused transmitting pulse to the ultrasonic probe 110 through the transmitting / receiving selection switch 120. The ultrasonic probe 110 is stimulated by the transmitting pulse to transmit an ultrasonic beam to the scanning target, and receives the ultrasonic echo reflected from the tissue corresponding to the scanning target after a certain delay, and reconverts the ultrasonic echo into an electrical signal. The receiving circuit 114 receives the electrical signal converted and generated by the ultrasonic probe 110, obtains the ultrasonic echo signal, and sends these ultrasonic echo signals to the beamforming module 122, and the beamforming module 122 performs a first processing operation on the ultrasonic echo data, and sends the processed ultrasonic echo signal to the processor 116, wherein the first processing operation performed by the beamforming module 122 on the ultrasonic echo data includes but is not limited to focusing delay, weighting and channel summing. The processor 116 is used to generate at least one frame of ultrasonic scanning image according to the echo signal.

[0041] The display 118 can display the ultrasound scan image obtained by the processor 116. In addition, while displaying the ultrasound scan image, the display 118 can also provide the user with a graphical interface for human-computer interaction. One or more controlled objects are set on the graphical interface, and the user is provided with a human-computer interaction device to input operation instructions to control these controlled objects, thereby performing corresponding control operations. For example, an icon is displayed on the graphical interface, and the icon can be operated by the human-computer interaction device to perform a specific function, such as drawing a region of interest box on the ultrasound scan image.

[0042] Optionally, the ultrasound imaging system 100 may further include other human-machine interaction devices in addition to the display 118, which are connected to the processor 116. For example, the processor 116 may be connected to the human-machine interaction device via an external input / output port, and the external input / output port may be a wireless communication module, or a wired communication module, or a combination of the two. The external input / output port may also be implemented based on USB, bus protocols such as CAN, and / or wired network protocols.

[0043] The human-computer interaction device may include an input device for checking the user's input information, which may be, for example, a control instruction for the ultrasonic transmission / reception timing, an operation input instruction for drawing points, lines or frames on an ultrasonic scanning image, or other instruction types. The input device may include a keyboard, a mouse, a scroll wheel, a trackball, a mobile input device (such as a mobile device with a touch screen, a mobile phone, etc.), a multi-function knob, etc., or a combination of multiple thereof. The human-computer interaction device may also include an output device such as a printer.

[0110] In the case where the ultrasound measurement instruction specifies a measurement item, determining the anatomical structure type corresponding to the target anatomical structure to be measured in the target ultrasound image according to the measurement item, obtaining position information and size information of the target anatomical structure matching the measurement item in the target ultrasound image, and using the anatomical structure type, the position information and the size information of the target anatomical structure in the target ultrasound image as the anatomical recognition result;

[0111] When the ultrasound measurement instruction does not specify a measurement item, the image category corresponding to the target ultrasound image is identified by a preset image recognition algorithm, and the measurement item corresponding to the target ultrasound image is obtained according to the image category; the anatomical structure type corresponding to the target anatomical structure to be measured in the target ultrasound image is determined according to the measurement item, and the position information and size information of the target anatomical structure matching the measurement item in the target ultrasound image are obtained; the anatomical structure type, the position information and the size information of the target anatomical structure in the target ultrasound image are used as the anatomical recognition result.

[0112] Exemplarily, different from the above-mentioned embodiment, in this embodiment, the ultrasonic measurement instruction is parsed to determine whether the ultrasonic measurement instruction specifies the measurement items of the target ultrasonic image, and then the corresponding operation is performed according to the determination result.

[0113] It can be understood that the method of performing image analysis or image recognition on the target ultrasound image can be: a preset machine learning model and / or feature recognition algorithm is stored in the memory 124, wherein the machine learning model may include a convolutional neural network (CNN), a support vector machine (SVM), a generative adversarial network (GAN), and / or other similar types of models trained using supervised, unsupervised and / or enhanced learning techniques. The machine learning model is used to extract and recognize features of the ultrasound scan image, thereby identifying the anatomical recognition results corresponding to each anatomical structure in the ultrasound scan image, wherein the anatomical recognition results at least include the anatomical type information of the target anatomical structure, the position information of the target anatomical structure in the target ultrasound image, and the size information of the target anatomical structure in the target ultrasound image.

[0114] For example, the machine learning model learns features and regresses parameters of the constructed database by stacking basic convolutional layers and fully connected layers. For an input target ultrasound image, the neural network in the machine learning model can regress the Bounding-Box of the region of interest corresponding to the target ultrasound image, and at the same time obtain the category of the anatomical structure in the region of interest, that is, the anatomical type of at least one anatomical structure corresponding to the target ultrasound image. Common neural networks include R-CNN, FastR-CNN, Faster-RCNN, SSD, YOLO, etc.

[0115] After acquiring the anatomical type corresponding to the anatomical structure in the target ultrasound image, the position information of the target anatomical structure in the target ultrasound image and the size information of the target anatomical structure in the target ultrasound image can be determined according to the structural edges of each target anatomical structure in the target ultrasound image.

[0116] For another example, the anatomical type corresponding to the anatomical structure in the target ultrasound image can be determined by a sliding window-based method. A common form is to first extract features from the area within the sliding window. The feature extraction method can be traditional PCA, LDA, Harr features, texture features, etc., or a deep neural network can be used for feature extraction. The extracted features are then matched with standard features in the database and classified using discriminators such as KNN, SVM, random forest, and neural networks, so as to determine whether the current sliding window is an area of ​​interest, that is, whether the current sliding window area has a corresponding target anatomical structure, and at the same time obtain the corresponding category of the target anatomical structure.

[0117] After acquiring the anatomical type corresponding to the anatomical structure in the target ultrasound image, the position information of the target anatomical structure in the target ultrasound image and the size information of the target anatomical structure in the target ultrasound image can be determined according to the structural edges of each target anatomical structure in the target ultrasound image.

[0118] like Figure 3 As shown, after the target ultrasound image is identified according to the ultrasound measurement instruction, it can be known from the obtained anatomical identification result that the target anatomical structure in the current target ultrasound image is the fetal brain, that is, the target ultrasound image is an ultrasound image of the fetal brain.

[0119] Furthermore, the anatomical recognition result can also be used to know that the center point O of the marked anatomical structure is located at O(x, y) in the ultrasound image, and the size information of the marked anatomical structure is S. The size information can be obtained by selecting the corresponding cranial brain structure in the target fetal cranial brain image through a target frame, and the area of ​​the target frame is used as the size information of the cranial brain structure. The shape of the target frame can be set as needed, for example, a circle, an ellipse, a triangle, a rectangle, etc., which are not limited here.

[0120] It can be understood that the target ultrasonic image can be at least one frame of ultrasonic scanning image of the scanning target acquired in real time by the ultrasonic imaging system 100, or it can be the ultrasonic scanning image of the scanning target acquired by the ultrasonic imaging system 100 and stored in the corresponding memory, and the processor 116 selects at least one frame of ultrasonic scanning image from the corresponding memory as the target ultrasonic image according to the ultrasonic measurement instruction, wherein the memory for storing the ultrasonic scanning image can be the internal memory of the ultrasonic imaging system 100, or it can be an external processor connected to the ultrasonic imaging system 100 for communication, which is not limited here.

[0121] In some embodiments, the method for acquiring the target ultrasound image can be: the processor of the ultrasound imaging system 100 controls the transmitting circuit 112 to excite the ultrasound probe 110 to transmit ultrasound to the scanning target, and obtains at least one frame of ultrasound scanning image of the scanning target according to the ultrasound echo signal corresponding to the ultrasound received by the receiving circuit 114; and uses the ultrasound scanning image of the current frame as the target ultrasound image according to the ultrasound measurement instruction.

[0122] Exemplarily, the processor 116 of the ultrasound imaging system 100 controls the transmitting circuit 112 to excite the ultrasound probe 110 to transmit ultrasound waves toward the scanning target of the target object, and drives the receiving circuit 114 to control the ultrasound probe 110 to receive the echo signal of the ultrasound waves, and generate at least one frame of ultrasound scanning image of the scanning target according to the echo signal.

[0123] It can be understood that the scanning targets include but are not limited to the neck, chest, abdomen, pelvic organs and limb blood vessels of the target object (such as the patient), and the target tissue corresponding to the scanning target can be the neck organs such as the thyroid gland, parotid gland, submandibular gland, and neck blood vessels. The target tissue corresponding to the scanning target can also be the chest organs such as the pleura, lungs, heart and surrounding large blood vessels, mediastinal lymph nodes, etc. The target tissue corresponding to the scanning target can also be the abdominal organs such as the liver, gallbladder, pancreas, spleen, kidney, ureter, bladder, uterus, ovary, fallopian tube, prostate, etc.

[0124] Ultrasonic waves are emitted to the position corresponding to the scanning target by the ultrasonic probe 110, and at least one frame of ultrasonic scanning image of the ultrasonic section corresponding to the scanning target is obtained according to the ultrasonic echo signal of the received ultrasonic wave, and the ultrasonic scanning image contains the anatomical structure features of the scanning target. That is, the ultrasonic inspection image of the scanning target obtained in this embodiment is an ultrasonic scanning image obtained in real time during the ultrasonic scanning of the scanning target by the ultrasonic imaging system 100.

[0125] In some embodiments, the method for acquiring the target ultrasound image can be: the processor of the ultrasound imaging system 100 controls the transmitting circuit 112 to stimulate the ultrasound probe 110 to transmit ultrasound to the scanning target, and obtains at least one frame of ultrasound scanning image of the scanning target according to the ultrasound echo signal corresponding to the ultrasound received by the receiving circuit 114, and stores the acquired at least one frame of ultrasound scanning image in a preset database, and selects at least one frame of ultrasound scanning image from the database as the target ultrasound image according to the received ultrasound measurement instruction.

[0126] Step S103: determining the measurement requirements of the target anatomical structure at least according to the anatomical type information, determining the image measurement strategy of the target ultrasound image according to the measurement requirements, and determining the image magnification strategy of the target ultrasound image at least according to the anatomical type information, size information and position information.

[0127] For example, in order to achieve accurate measurement of various anatomical structures, it is necessary to determine the corresponding image magnification strategy based on the recognition result of the target anatomical structure in the target ultrasound image, so as to accurately measure the target anatomical result in the target ultrasound image after being magnified by the image magnification strategy.

[0128] Furthermore, corresponding measurement requirements are set for different anatomical structures, and corresponding image measurement strategies are set for different measurement requirements, so that the measurement of each target anatomical structure in the target ultrasound image can be accurately achieved through the corresponding image measurement strategy.

[0129] The memory 124 stores a first association relationship between anatomical type information and measurement requirements, and a second association relationship between measurement requirements and image measurement strategies. After the anatomical type information corresponding to the target anatomical structure in the target ultrasound image is acquired, the measurement requirements matching the anatomical type information are acquired based on the anatomical type information and the first association relationship, and the image measurement strategy for measuring the target anatomical structure is acquired based on the measurement requirements and the second association relationship.

[0130] At the same time, the memory 124 stores the anatomical type information of the target anatomical structure, the position information of the target anatomical structure in the target ultrasound image, the size information of the target anatomical structure in the target ultrasound image and the third association relationship between the image magnification strategy. After obtaining the anatomical recognition result of the target anatomical structure in the target ultrasound image, the image magnification strategy of the target ultrasound image can be obtained based on the anatomical recognition result and the third association relationship.

[0131] Optionally, determining a measurement requirement of the target anatomical structure at least according to the anatomical type information, and determining an image measurement strategy of the target ultrasound image according to the measurement requirement, includes:

[0132] The measurement requirements of the target anatomical structure are determined according to the anatomical type information and the examination item information of the target object, and the image measurement strategy of the target ultrasound image is determined according to the measurement requirements, and the scanning target is a partial tissue structure of the target object.

[0133] In some embodiments, the image magnification strategy of the target ultrasound image is determined at least based on the anatomical type information, size information and position information, including: determining the image magnification strategy of the target ultrasound image based on the examination item information, anatomical type information, size information and position information of the target object, and the scanning target is a partial tissue structure of the target object.

[0134] For example, in some scenarios, the image magnification and measurement of the target anatomical structure in the target ultrasound image are related to the examination item of the target object. Therefore, in order to more accurately measure the target anatomical structure in the target ultrasound image, it is also necessary to determine the current examination item of the target object.

[0135] The target ultrasound image is associated with the inspection item information of the target object. After determining the target ultrasound image to be subjected to image analysis, the target object and the inspection item information of the target object that match the target ultrasound image can be determined based on the target ultrasound image. After obtaining the inspection item of the target object, according to the first association relationship corresponding to the anatomical type information, the inspection item and the measurement requirement stored in the memory 124, and the second association relationship between the measurement requirement and the image measurement strategy, after obtaining the anatomical type information corresponding to the target anatomical structure in the target ultrasound image, the measurement requirement matching the anatomical type information is obtained based on the anatomical type information, the inspection item and the first association relationship, and the image measurement strategy for measuring the target anatomical structure is obtained based on the measurement requirement and the second association relationship.

[0136] At the same time, the memory 124 stores a third association relationship between the examination item, the anatomical type information of the target anatomical structure, the position information of the target anatomical structure in the target ultrasound image, the size information of the target anatomical structure in the target ultrasound image and the image magnification strategy. After obtaining the anatomical recognition result of the target anatomical structure in the target ultrasound image, the image magnification strategy of the target ultrasound image can be obtained based on the anatomical recognition result, the examination item and the third association relationship.

[0137] For example, the target object is a pregnant woman, and the examination item to be performed is an obstetric ultrasound examination. However, the target object is not limited to only patients who need an obstetric ultrasound examination.

[0138] Usually, a woman's pregnancy is divided into three stages: early, middle, and late. The early stage of pregnancy usually refers to the period from the beginning of pregnancy to the 13th week of pregnancy, the middle stage from the 14th to the 27th week of pregnancy, and the late stage of pregnancy after the 28th week. Different pregnancy stages correspond to different examination items. Or, the fetal development status of different target objects is different, and the corresponding examination items are different.

[0139] Because the same target anatomical structure has different developmental degrees in different gestational periods, and the data to be measured are also different, the same target anatomical structure in different gestational periods has different sizes and / or positions in the target ultrasound image, and the measurement requirements of the target anatomical structure are also different. If the same image magnification strategy is used in different examination items to magnify the target ultrasound image where the target anatomical structure is located, and the same image measurement strategy is used to measure the target anatomical structure, there may be defects such as poor magnification effect of the target anatomical structure and inaccurate measurement data.

[0140] Therefore, in order to achieve accurate magnification and measurement of the target anatomical structure under the corresponding examination item, in this embodiment, the image measurement strategy corresponding to the target anatomical structure in the target ultrasound image is associated with the examination item and the anatomical recognition result corresponding to the target anatomical structure, and / or the image magnification strategy corresponding to the target anatomical structure in the target ultrasound image is associated with the examination item and the anatomical recognition result corresponding to the target anatomical structure.

[0141] Step S104: amplify the target ultrasound image according to the image amplification strategy to obtain an ultrasound amplified image including the amplified target anatomical structure, and measure the target anatomical structure in the ultrasound amplified image according to the image measurement strategy to obtain a measurement result of the target anatomical structure.

[0142] Exemplarily, after obtaining the image magnification strategy and image measurement strategy corresponding to the target ultrasound image, the target ultrasound image is first magnified according to the image magnification strategy, and the target anatomical structure in the magnified ultrasound image is measured using the image measurement strategy to obtain a more accurate measurement result.

[0143] In some embodiments, the image magnification strategy includes at least a magnification factor of the target ultrasound image and a magnification center point corresponding to the target ultrasound image, and magnifying the target ultrasound image according to the image magnification strategy includes:

[0144] An amplification operation of a magnification factor is performed on the target ultrasonic image with the amplification center point as the amplification center of the target ultrasonic image to obtain an ultrasonic amplified image, wherein the amplification center point is the image center point of the target ultrasonic image, or the amplification center point is the region center point of the target structure region where the target anatomical structure is located in the target ultrasonic image.

[0145] See also Figure 4 Exemplarily, the image magnification strategy includes a magnification factor of the target ultrasound image and a magnification center point corresponding to the target ultrasound image.

[0146] Optionally, the magnification center point of the target ultrasound image may be determined based on the position information of the target anatomical structure in the target ultrasound image and the size information of the target anatomical structure in the target ultrasound image. The magnification factor of the target ultrasound image may be determined based on the anatomical type information, or the magnification factor of the target ultrasound image may be determined based on the anatomical type information and the size information of the target anatomical structure in the target ultrasound image, or the anatomical type information, the size information of the target anatomical structure in the target ultrasound image and the examination item information.

[0147] For example, the magnification center point is the center point O of the target anatomical structure in the target ultrasound image, and the magnification factor is α. In the process of magnifying the target ultrasound image, the target ultrasound image is magnified by α times with the magnification center point (point O) as the magnification center of the target ultrasound image to obtain an ultrasound magnified image.

[0148] like Figure 4 As shown, the target ultrasound image includes the target anatomical structure to be measured as the fetal cranial brain. According to the image recognition result, the size of the region of interest (the region where the target anatomical structure is located) in the target ultrasound image is a square frame with a side length of L, and the center point of the region of interest is point O. The upper and lower diameters of the target ultrasound image are H. Assuming that the magnification rule is to center the target anatomical structure to be measured, and to magnify the long axis of the target anatomical structure to more than 1 / 3 of the upper and lower diameters of the target ultrasound image, the magnification factor α can be set to α≥H / (3L), and the center point O of the region of interest can be used as the magnification center point when magnifying.

[0149] Alternatively, the magnification center point is the center point O1 of the target ultrasonic image, and the magnification factor is α. In the process of magnifying the target ultrasonic image, the target ultrasonic image is magnified by α times with the magnification center point (O1) as the magnification center of the target ultrasonic image to obtain an ultrasonic magnified image.

[0150] In some embodiments, the image magnification strategy includes at least a magnification factor of the target ultrasound image and a magnification center point corresponding to the target ultrasound image. In order to improve the preview effect of the magnified ultrasound image, the target ultrasound image is magnified according to the image magnification strategy, including:

[0151] Obtaining position deviation information between the magnification center point and a display center point corresponding to a display interface on which the display displays the target ultrasound image; determining a target translation direction and a target translation amount of the target ultrasound image on the display interface according to the position deviation information, and controlling the target ultrasound image to translate in the target translation direction on the display interface until the translation amount of the target ultrasound image in the target translation direction reaches the target translation amount;

[0152] During the translation of the target ultrasonic image, a magnification operation is performed on the target ultrasonic image with a magnification factor with a magnification center point as the magnification center of the target ultrasonic image to obtain an ultrasonic magnified image, wherein the magnification center point is the image center point of the target ultrasonic image, or the magnification center point is the region center point of a target structure region where a target anatomical structure is located in the target ultrasonic image.

[0153] Exemplarily, when the center point corresponding to the enlarged target anatomical structure and the display center point usually coincide with each other, or when the center point corresponding to the enlarged target ultrasound image and the display center point coincide with each other, the enlarged target anatomical structure is displayed at the display center of the corresponding display interface or close to the display center of the display interface, and the display center is usually the focus of the user's field of view, so that the enlarged target anatomical structure can have a better image reading effect.

[0154] In this implementation, an example is taken in which the magnification center point is the center point (point O) of the target anatomical structure in the target ultrasound image and the magnification factor is α.

[0155] During the image magnification process, the position deviation information between the magnification center point (point O) and the display center point (point O2) corresponding to the display interface is first determined, and the target translation direction and target translation amount of the target ultrasonic image on the display interface are determined based on the position deviation information, and the target ultrasonic image is controlled to be translated in the target translation direction on the display interface until the translation amount of the target ultrasonic image in the target translation direction reaches the target translation amount, so that the magnification center point (point O) and the display center point (point O2) corresponding to the display interface coincide or approximately coincide, and in order to save the time required for image magnification, during the translation process of the target ultrasonic image, an α-fold magnification operation is performed on the target ultrasonic image with the magnification center point (point O) as the magnification center of the target ultrasonic image to obtain an ultrasonic magnified image.

[0156] In some embodiments, the image magnification strategy includes at least a magnification factor of the target ultrasound image and a magnification center point corresponding to the target ultrasound image, and magnifying the target ultrasound image according to the image magnification strategy includes:

[0157] Acquire position deviation information between the magnification center point and a display center point corresponding to a display interface on which the display displays the target ultrasound image;

[0158] Determine a target translation direction and a target translation amount of the target ultrasound image on the display interface according to the position deviation information, and control the target ultrasound image to translate in the target translation direction on the display interface until the translation amount of the target ultrasound image in the target translation direction reaches the target translation amount;

[0159] After the target ultrasound image is translated, if no image position adjustment instruction is received from the target operation object triggered by the user within a preset time, a magnification operation is performed on the target ultrasound image with a magnification center point as the magnification center of the target ultrasound image to obtain an ultrasound magnified image;

[0160] If an image position adjustment instruction is received from the target operation object triggered by the user within a preset time, the position of the target ultrasound image on the display interface is adjusted according to the image position adjustment instruction, and after the position adjustment of the target ultrasound image is completed, a magnification operation is performed on the target ultrasound image with a magnification factor with the magnification center point as the magnification center of the target ultrasound image to obtain an ultrasonic magnified image, wherein the magnification center point is the image center point of the target ultrasound image, or the magnification center point is the regional center point of the target structure region where the target anatomical structure in the target ultrasound image is located.

[0161] In this implementation, an example is taken in which the magnification center point is the center point (point O) of the target anatomical structure in the target ultrasound image and the magnification factor is α.

[0162] During the image magnification process, the position deviation information between the magnification center point (point O) and the display center point (point O2) corresponding to the display interface is first determined, and the target translation direction and target translation amount of the target ultrasound image on the display interface are determined according to the position deviation information, and the target ultrasound image is controlled to translate in the target translation direction on the display interface until the translation amount of the target ultrasound image in the target translation direction reaches the target translation amount, so that the magnification center point (point O) and the display center point (point O2) corresponding to the display interface coincide or approximately coincide.

[0163] After the target ultrasonic image completes the translation, if no image position adjustment instruction is received from the user triggering the target operation object (such as a stylus or finger) within the preset time, the target ultrasonic image is magnified α times with the magnification center point (point O) as the magnification center of the target ultrasonic image to obtain an ultrasonic magnified image. The preset time can be set as needed, such as 1s, 2s, 3s, 3.5s, etc.

[0164] If an image position adjustment instruction is received from the target operation object triggered by the user within the preset time, the position of the target ultrasound image on the display interface is adjusted according to the image position adjustment instruction, and after the position adjustment of the target ultrasound image is completed, the target ultrasound image is magnified α times with the magnification center point (point O) as the magnification center of the target ultrasound image to obtain an ultrasonic magnified image.

[0165] Optionally, during the process of completing the translation of the marked ultrasound image, or after the translation of the marked ultrasound image is completed, the enlarged center point is marked in the display interface to facilitate the user to visually judge whether there is an obvious deviation between the enlarged center point and the display center point, wherein the method of marking the enlarged center point includes displaying a corresponding icon at the enlarged center point, such as a circle icon, a triangle icon, a rectangular icon, etc.

[0166] In this embodiment, based on the different image viewing habits of different users, after the image is translated, if the magnification center point corresponding to the target ultrasound image is not the magnification center point desired by the user, the user can adjust the position of the target ultrasound image as required, so as to adjust the position of the magnification center point to the position desired by the user and then magnify the image, so that the display position of the target anatomical structure in the magnified ultrasound image in the display interface meets the image reading habits of the user.

[0167] In some embodiments, the image magnification strategy includes at least a magnification factor of the target ultrasound image and a magnification center point corresponding to the target ultrasound image, and magnifying the target ultrasound image according to the image magnification strategy includes:

[0168] Performing a magnification operation on the target ultrasonic image with a magnification factor with the magnification center point as the magnification center of the target ultrasonic image to obtain an ultrasonic magnified image, wherein the magnification center point is the image center point of the target ultrasonic image, or the magnification center point is the region center point of the target structure region where the target anatomical structure is located in the target ultrasonic image;

[0169] Acquire position deviation information between the magnification center point and a display center point corresponding to a display interface on which the display displays the target ultrasound image;

[0170] The target translation direction and target translation amount of the ultrasonic amplified image on the display interface are determined according to the position deviation information, and the ultrasonic amplified image is controlled to translate in the target translation direction on the display interface until the translation amount of the ultrasonic amplified image in the target translation direction reaches the target translation amount.

[0171] For example, in this embodiment, the magnification center point is taken as the center point (point O) of the target anatomical structure in the target ultrasound image, and the magnification factor is α.

[0172] During the image magnification process, the target ultrasound image is first magnified α times with the magnification center point (point O) as the magnification center to obtain the ultrasound magnified image. After the image magnification is completed, the position deviation information between the magnification center point (point O) and the display center point (point O2) corresponding to the display interface is determined, and the target translation direction and target translation amount of the ultrasound magnified image on the display interface are determined based on the position deviation information, and the ultrasound magnified image is controlled to translate in the target translation direction on the display interface until the translation amount of the ultrasound magnified image in the target translation direction reaches the target translation amount, so that the magnification center point (point O) and the display center point (point O2) corresponding to the display interface coincide or approximately coincide.

[0173] In some embodiments, measuring the target anatomical structure in the ultrasound magnified image according to the image measurement strategy includes:

[0174] A measurement target is determined from the target anatomical structure in the ultrasound amplified image according to the image measurement strategy, and each measurement target in the target anatomical structure is measured to obtain a measurement result of the target anatomical structure.

[0175] Exemplarily, an image measurement strategy matching the target anatomical structure associates various measurement targets to be measured in the target anatomical structure and a measurement sequence of each measurement target, and measures each measurement target in the target anatomical structure according to the measurement sequence, thereby obtaining a measurement result of the target anatomical structure.

[0176] For example, the target anatomical structure is the fetal head. At this time, according to the measurement requirements, it is necessary to record the main structures in the fetal head, such as the cavum septum pellucidum, thalamus, Sylvian fissure, lateral ventricles, cerebellum, cerebellar vermis, and cerebellomedullary cistern. That is, when the target anatomical structure is the fetal head, the measurement targets at least include the cavum septum pellucidum, thalamus, Sylvian fissure, lateral ventricles, cerebellum, cerebellar vermis, and cerebellomedullary cistern. By measuring each measurement target, the measurement result of the fetal head is obtained.

[0177] When the target anatomical structure is the whole body of the fetus, at this time, according to the measurement requirements, it is necessary to record the basic parts of the fetus such as the head, spine, heart, abdomen and limbs. That is, when the target anatomical structure is the whole body of the fetus, the measurement targets at least include the head, spine, heart, abdomen and limbs, and the measurement results of the whole body of the fetus are obtained by measuring each measurement target.

[0178] In some embodiments, measuring the target anatomical structure in the ultrasound magnified image according to the image measurement strategy includes:

[0179] The measurement target is determined from the target anatomical structure according to the image measurement strategy, and each measurement target is segmented from the ultrasound amplified image, and each measurement target is measured based on the image segmentation result, so as to obtain the measurement result of the target anatomical structure.

[0180] Exemplarily, the image measurement strategy associates each measurement target to be measured in the target anatomical structure, segments each measurement target from the ultrasound amplified image, and measures each measurement target based on the image segmentation result, thereby obtaining a measurement result of the target anatomical structure.

[0181] For example, when the target anatomical structure is a fetal head, the measurement targets include at least the cavum septum pellucidum, thalamus, lateral fissure, lateral ventricle, cerebellum, cerebellar vermis, and cerebellomedullary cistern. Regional images corresponding to the measurement targets such as the cavum septum pellucidum, thalamus, lateral fissure, lateral ventricle, cerebellum, cerebellar vermis, and cerebellomedullary cistern are segmented from the ultrasound magnified image, and each measurement target in each segmented regional image is measured, thereby obtaining a measurement result of the fetal head.

[0182] Optionally, the image segmentation method includes a threshold-based segmentation method, that is, one or more thresholds are selected according to the grayscale characteristics of the image to divide the image into several regions. Commonly used threshold segmentation methods include global threshold segmentation, local threshold segmentation, and adaptive threshold segmentation.

[0183] Optionally, the image segmentation method also includes an edge-based segmentation method, that is, the image is divided into different regions by detecting edges in the image. Commonly used edge detection methods include Sobel operator, Canny operator, Laplacian operator, etc.

[0184] Optionally, the image segmentation method also includes a region-based segmentation method, that is, the image is divided into different regions according to the similarity and proximity between pixels in the image. Commonly used region segmentation methods include region growing, region separation aggregation, watershed algorithm, etc.

[0185] Optionally, the image segmentation method also includes a segmentation method based on deep learning, that is, using deep learning technology to train and classify images to achieve automatic image segmentation. Commonly used deep learning segmentation methods include convolutional neural network (CNN) segmentation, U-Net segmentation, Mask R-CNN segmentation, etc.

[0186] Optionally, the image segmentation method also includes a texture-based method, that is, the image is segmented according to different characteristics of the ground object texture (roughness, similarity, etc.), mainly using gray-level co-occurrence matrix, fractal theory, histogram moment and other methods.

[0187] Optionally, the image segmentation method also includes a segmentation method based on wavelet transform, that is, decomposing the image histogram into wavelet coefficients of different levels by binary wavelet transform, then selecting a threshold value based on given segmentation criteria and wavelet coefficients, and finally using the threshold value to mark the image segmentation area.

[0188] In some embodiments, measuring the target anatomical structure in the ultrasound magnified image according to the image measurement strategy includes:

[0189] According to the image measurement strategy, the measurement target is determined from the target anatomical structure, and each measurement target is segmented from the ultrasonic magnified image. The size ratio of each measurement target and the ultrasonic magnified image is determined based on the image segmentation result. Based on the size ratio, each adapted measurement target is secondary magnified, and each measurement target after the secondary magnification is measured, so as to obtain the measurement result of the target anatomical structure.

[0190] Exemplarily, the image measurement strategy associates each measurement target to be measured in the target anatomical structure, segments each measurement target from the ultrasound magnified image, and performs secondary magnification and measurement on each measurement target to display more image details, thereby making the measurement result of the target anatomical structure more accurate.

[0191] For example, when the target anatomical structure is the fetal head, the measurement targets include at least the cavum septum pellucidum, thalamus, lateral fissure, lateral ventricle, cerebellum, cerebellar vermis, and cerebellomedullary cistern. The regional images corresponding to the measurement targets such as the cavum septum pellucidum, thalamus, lateral fissure, lateral ventricle, cerebellum, cerebellar vermis, and cerebellomedullary cistern are segmented from the ultrasonic magnified image, and each segmented regional image is magnified according to a preset ratio. The preset ratio can be set according to the size ratio corresponding to the measurement target and the ultrasonic magnified image, or it can be set uniformly, which is not limited here. After the image is magnified twice, the measurement targets in each regional image are measured to obtain the measurement results of the fetal head.

[0192] Step S105: Control the display 118 to display the measurement result of the target anatomical structure.

[0193] For example, after obtaining the measurement result of the target anatomical structure in the target ultrasound image, the measurement result of the target anatomical structure is displayed on a preset display interface by controlling the display 118, and the measurement result at least includes the measurement data of the target anatomical structure, the measurement analysis opinion, the image of the target anatomical structure, etc. It can be understood that the displayed measurement result can be adjusted as needed.

[0194] See also Figure 5 , Figure 5 It is a schematic flowchart of a method for measuring an ultrasonic image provided in an embodiment of the present application.

[0195] The ultrasound image measurement method provided in the embodiment of the present application may be applied to the aforementioned ultrasound imaging system 100 and executed by the processor 116 of the ultrasound imaging system 100 .

[0196] like Figure 5 As shown, the ultrasound image measurement method includes steps S201 to S206.

[0197] Step S201: controlling the transmitting circuit to excite the ultrasonic probe to transmit ultrasonic waves to the scanning target, and obtaining at least one frame of ultrasonic scanning image of the scanning target according to the ultrasonic echo signal corresponding to the ultrasonic waves received by the receiving circuit.
