Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an ultrasonic imaging device and an ultrasonic inspection method thereof. Background Art

[0002] For scientific research applications, the design often involves N groups of animals (with multiple control groups), with each group often containing dozens or even hundreds of animals. Ultrasound equipment is used to observe the heart, abdomen, etc., and images need to be taken one by one. The data for each animal must be recorded, stored, and analyzed separately, and finally all the data are put together for statistics and comparison. However, due to time requirements for experimental animals, all animals must be examined within a few days or even one or two days. Therefore, when performing color ultrasound, it is often necessary to first concentrate on taking images of all animals, and then perform post-processing operations such as measurements, and then summarize the data of all animals. Therefore, when taking ultrasound images of experimental animals, due to the large number of experimental animals, not only does it take a long time to operate the ultrasound instrument, but also the post-processing time and data statistical processing time for all images after the imaging is completed is also very long.

[0057] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0058] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0059] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0060] The ultrasonic imaging device and ultrasonic inspection method provided by the present invention provide an automated workflow, enabling automatic identification of target objects, automatic creation of scanning tasks, automatic image generation, automatic measurement, and batch export. These devices are ideal for high-volume, repetitive ultrasonic inspections for scientific research, and offer high inspection efficiency. These are described in detail below using several examples.

[0061] like Figure 1 As shown, the ultrasonic imaging device provided by the present invention includes an ultrasonic probe 10, a transmitting / receiving control circuit (30 and 40), a processor 20, a human-computer interaction device 70 and a memory 80.

[0062] The ultrasound probe 10 includes a transducer (not shown) composed of multiple array elements arranged in an array. The array elements are used to transmit ultrasonic waves in response to excitation electrical signals or to convert received ultrasonic waves into electrical signals. Therefore, each array element can be used to convert electrical pulse signals into and from ultrasonic waves, thereby transmitting ultrasonic waves to the target biological tissue and receiving echoes of ultrasonic waves reflected from the tissue.

[0063] The transmitting / receiving control circuit is used to control the ultrasonic probe 10 to transmit ultrasonic waves to the region of interest and receive the echo of the ultrasonic waves. The transmitting / receiving control circuit includes a transmitting control circuit 30 and a receiving control circuit 40.

[0064] The transmission control circuit 30 is used to stimulate the ultrasound probe 10 to transmit ultrasound waves toward the target object according to the control of the processor 20 .

[0065] The receiving control circuit 40 is used to receive ultrasonic echoes returned from the target object through the ultrasonic probe 10 to obtain ultrasonic echo signals, and can also process the ultrasonic echo signals. The receiving control circuit 40 may include one or more amplifiers, analog-to-digital converters (ADCs), etc.

[0066] The human-computer interaction device 70 is used for human-computer interaction, such as outputting visual information and receiving user input. The user input may be received using a keyboard, operating buttons, mouse, trackball, touchpad, or a touch screen integrated with a display. The visual information may be output using a display.

[0067] The memory 80 is used to store various types of data.

[0068] The ultrasound imaging apparatus may further include a beamforming module 50 and an IQ demodulation module 60 .

[0069] The beamforming module 50 is signal-connected to the receiving control circuit 40 and is used to perform beamforming processing, such as delay and weighted summation, on the echo signals. Because the distances between the ultrasound receiving points in the measured tissue and the receiving elements vary, the channel data for the same receiving point output by different receiving elements have different delays. This requires delay processing, phase alignment, and weighted summation of the different channel data for the same receiving point to obtain beamformed ultrasound image data. The ultrasound image data output by the beamforming module 50 is also referred to as radio frequency data (RF data). The beamforming module 50 outputs the RF data to the IQ demodulation module 60. In some embodiments, the beamforming module 50 may also output the RF data to the memory 80 for caching or storage, or directly output the RF data to the processor 20 for image processing.

[0070] The beamforming module 50 can perform the above functions in the form of hardware, firmware or software. The beamforming module 50 can be integrated into the processor 20 or set separately, which is not limited in the present invention.

[0071] The IQ demodulation module 60 removes the signal carrier through IQ demodulation, extracts the tissue structure information contained in the signal, and performs filtering to remove noise. The resulting signal is called a baseband signal (IQ data pair). The IQ demodulation module 60 outputs the IQ data pair to the processor 20 for image processing. In some embodiments, the IQ demodulation module 60 also outputs the IQ data pair to the memory 80 for caching or storage, so that the processor 20 can read the data from the memory 80 for subsequent image processing.

[0072] The IQ demodulation module 60 may also perform the above functions in the form of hardware, firmware or software. Similarly, the IQ demodulation module 60 may be integrated into the processor 20 or may be provided separately, which is not limited in the present invention.

[0073] The processor 20 is configured to be a central control circuit (CPU), one or more microprocessors, a graphics controller circuit (GPU) or any other electronic component that can process input data according to specific logical instructions. It can control peripheral electronic components according to input instructions or predetermined instructions, or read and / or save data from the memory 80. It can also process the input data by executing the program in the memory 80, for example, performing one or more processing operations on the collected ultrasound data according to one or more working modes. The processing operations include but are not limited to adjusting or limiting the form of ultrasound waves emitted by the ultrasound probe 10, generating various image frames for subsequent display on the display of the human-computer interaction device 70, or adjusting or limiting the content and form displayed on the display, or adjusting one or more image display settings displayed on the display (such as ultrasound images, interface components, and positioning areas of interest).

[0074] As echo signals are received, the acquired ultrasound data may be processed by the processor 20 in real time during scanning, or may be temporarily stored on the memory 80 and processed in quasi-real time in either on-line or off-line operation.

[0075] In this embodiment, the processor 20 controls the operation of the transmit control circuit 30 and the receive control circuit 40, for example, controlling the transmit control circuit 30 and the receive control circuit 40 to operate alternately or simultaneously. The processor 20 may also determine an appropriate operating mode based on a user's selection or program settings, form a transmit sequence corresponding to the current operating mode, and send the transmit sequence to the transmit control circuit 30 so that the transmit control circuit 30 uses the appropriate transmit sequence to control the ultrasound probe 10 to transmit ultrasonic waves.

[0076] The processor 20 is also used to process the ultrasound data to generate a grayscale image of the signal strength changes within the scanning range. The grayscale image reflects the anatomical structure inside the tissue, which is called a B image. The processor 20 can output the B image to the display of the human-computer interaction device 70 for display.

[0077] Existing ultrasound imaging equipment is usually operated by ultrasound doctors who are experienced and can skillfully use the complex functions of ultrasound imaging equipment. For other medical staff, ultrasound imaging equipment has various functions and requires a lot of time and energy to learn before they can use it. In the scenario of scientific research applications, both ultrasound doctors and other medical staff need to manually inspect and measure a large number of experimental animals, which takes a long time. Taking the application of myocardial infarction research as an example, mice are generally used as experimental animals. The operating procedures for users to use ultrasound imaging equipment are as follows:

[0078] 1. Place the mouse in an anesthesia induction box for anesthesia.

[0079] 2. After anesthesia, the mouse is fixed on the experimental table, and the anesthesia tube is inserted into the mouth and nose for continuous anesthesia. At the same time, the mouse's abdomen is depilated.

[0080] 3. Each mouse wears an "earring" with a number on it. The operator creates a new animal on the ultrasound instrument and enters the mouse number as the animal identification ID.

[0081] 4. Then select the mouse probe and heart examination mode. Based on the purpose of the experiment, create an image of the corresponding section of the mouse heart. Place the probe on the section to be scanned, scan the B-mode image, and select whether to scan B+M, B+C, or B+C+PW modes as needed. Save the image. Then place the probe on the next scan section and repeat the above steps. It should be noted that there are many sections of the heart, but generally only a few of them are scanned in experiments. Experimental heart scans are different from clinical heart scans in hospitals. Clinically, as many complete hearts as possible are scanned to rule out possible problems with the heart. Experiments have clear purposes and observation objects, so generally only a few clear sections or even only 1-2 sections are scanned. At the same time, only the B+M, B+C, or B+C+PW modes are scanned according to needs. B-mode images are definitely scanned.

[0082] 5. After inspecting one mouse, end the inspection and create the next animal. Enter the number of the next mouse and repeat steps 1-4 until all mice have been inspected.

[0083] 6. All examination data are then post-processed on the machine (or if separate post-processing software is available, the data can be exported to the post-processing software on the PC). For example, various chambers and wall thicknesses can be measured on the M image, and the intravascular flow velocity can be measured on the PW atlas.

[0084] 7. Then export all inspection images, measurement data, etc. and organize them into data tables for summary.

[0085] As can be seen from the above steps, users need to manually operate step by step, which is very time-consuming when testing a large number of experimental mice. The ultrasonic imaging equipment provided by the present invention can improve the automation level of the experimental inspection process, thereby improving the user's work efficiency. Figure 2 As shown, the processor 20 controls the ultrasonic imaging device to perform ultrasonic examination, which specifically includes the following steps:

[0086] Step 1. The processor 20 receives an instruction for starting an experimental inspection process through the human-computer interaction device 70, and starts the experimental inspection process in response to the instruction. The experimental inspection process is used to guide the user to complete the scanning task of multiple target objects and obtain the measurement results of the ultrasound images of the target objects. The instruction for starting the experimental inspection process may include: an instruction for switching the working mode to the experimental mode. For example, virtual buttons for multiple working modes can be set on the display interface, one of which is the experimental mode. The user operates the human-computer interaction device 70 to select the virtual button of the experimental mode, and then an instruction for switching the working mode to the experimental mode is issued. Of course, a physical button can also be set. After the user triggers the physical button, an instruction for switching the working mode to the experimental mode is issued. In the experimental mode, the processor 20 starts the preset experimental inspection process.

[0087] Step 2: The processor 20 obtains operation sequence information of the experimental inspection process based on the user's operation. The operation sequence information is pre-associated with a set of ultrasound parameters.

[0088] There are many ways to obtain the operation sequence information of the experimental inspection process. Two of them are specifically introduced below.

[0089] One approach is for the processor 20 to display a settings page on the display interface of the human-computer interaction device 70, allowing the user to select the operational sequence information for the experimental examination process. The operational sequence information may include multiple options for animal type, examination site, section, image mode, and image post-processing method. This embodiment uses these five as an example for description. For example, the settings page presents multiple selectable animal types for the user to select, such as mouse, cat, and dog. Different animal types determine certain parameters for ultrasound scanning, examination site, and subsequent image processing (these parameters vary with animal type). In other words, each animal type is pre-associated with a set of ultrasound parameters that are applicable to that animal type. When the user selects an animal type, the selected animal type becomes the target animal type. The settings page presents multiple selectable examination sites pre-associated with the target animal type for the user to select, such as heart, lungs, and abdomen. The examination site is also pre-associated with a set of ultrasound parameters. For example, different examination sites may have different associated sections, ultrasound image annotations, body map names / types, and measurement items. When the user selects an examination site, the selected examination site becomes the target examination site. The setup page presents a variety of pre-associated, selectable sections for the target examination area, such as the long-axis four-chamber view and the short-axis main pulmonary artery view. Each section is also pre-associated with a set of ultrasound parameters. For example, different sections may have different associated image modes, image post-processing methods, ultrasound image annotations, and measurement items. The user selects a section, and the selected section becomes the target section. The setup page presents a variety of pre-associated, selectable image modes and / or image post-processing methods for the target section to select. Examples of image modes include B-mode, M-mode, C-mode, PW-mode, B+M-mode, B+C-mode, and B+C+PW-mode. Each image mode is also pre-associated with a set of ultrasound parameters. B and B+M images can be scanned on the long-axis four-chamber view, while B, B+C, and B+C+PW images can be scanned on the short-axis main pulmonary artery view. The user selects an image mode, and the selected image mode becomes the target image mode. Image post-processing methods can be measurement items.For example, on the long-axis four-chamber view, measurements on the B image include LA Diam (left atrial diameter), and on the M image include: IVSd (diastolic interventricular septal thickness), LVIDd (left ventricular short-axis diameter at end-diastole), LVPWd (left ventricular posterior wall thickness at end-diastole), IVSs (systolic interventricular septal thickness), LVIDs (left ventricular short-axis diameter at end-systole), LVPWs (left ventricular posterior wall thickness at end-systole), LVEDV (left ventricular end-diastolic volume), LVESV (left ventricular end-systolic volume), FS (fractional shortening), and EF (ejection fraction). On the short-axis main pulmonary artery view, no operations are required on the B image or C image. The measurement required on the PW atlas is pulmonary artery velocity (B images are used to facilitate visualization of blood vessels, while C images are used to confirm blood flow, both in preparation for the PW image). The user selects an image post-processing method, which becomes the target image post-processing method.

[0090] That is, the user can select the operation sequence information of the current experimental inspection process on the setting page, and the processor 20 obtains the operation sequence information (target animal type, target inspection part, target section, target image mode and image post-processing target method) selected by the user based on the user's selected operation on the setting page.

[0091] Another approach is for the processor 20 to record the user's operation of the ultrasound imaging device to perform the task of scanning the initial target object, obtain the operation sequence information used in the process, and use this operation sequence information as the operation sequence information for the current experimental examination process. In other words, the processor 20 can obtain the operation sequence information for the current experimental examination process by "recording" the user's operations. The "recording" can be performed when the user examines the first mouse; or the "recording" can be performed in advance, and the user-selected operation sequence information can be used when examining the first mouse. These are described below.

[0092] For example, the processor 20 obtains the identifier of the initial target object and creates a new scanning task for the initial target object based on the identifier; the processor 20 receives a recording start instruction through the human-computer interaction device 70; the instruction can be triggered by a specific button in the human-computer interaction device 70, or by clicking a cursor in some display interfaces. In response to the recording start instruction, the processor 20 displays a scanning interface through the human-computer interaction device 70, records the scanning operations performed by the user based on the scanning interface, and obtains the target animal type, target inspection part, target section, target image mode, and target image post-processing method. Among them, the scanning operation includes the operation of drawing an image, freezing the image, selecting a frame and saving the image, annotating the image, and unfreezing the image; the annotation operation includes adding at least one of a body position map, annotations, and measurements.

[0093] For another example, the processor 20 receives a recording start command via the human-computer interface 70. In response to the recording start command, the processor 20 displays a scanning interface via the human-computer interface 70, and records the scanning operation performed by the user based on the scanning interface, thereby obtaining the target animal type, target examination site, target section, target image mode, and target image post-processing method. In other words, the user can perform conventional operations on the ultrasound imaging device without scanning a specific mouse.

[0094] Step 3: Processor 20 obtains the target object's identifier. The target object's identifier is used to uniquely identify the target object and can be a number, ID, etc. The target object is typically an experimental animal. In this embodiment, the target object is a mouse, and a tag with the mouse's number is set on its ear.

[0095] The identification of the target object can be manually input by the user, that is, the processor 20 receives the identification of the target object input by the user through the human-computer interaction device 70. Of course, the identification of the target object can also be automatically identified, that is, the processor 20 identifies the label of the target object to obtain the identification of the target object. Specifically, the ultrasonic imaging device also includes an identification device (not shown in the figure), and the processor 20 identifies the label of the target object in the anesthesia induction box through the identification device to obtain the identification of the target object. The anesthesia induction box is used to anesthetize the target object. The identification device can be set on the anesthesia induction box to facilitate the identification of the target object. The identification device can be a camera, which captures the label of the target object and then identifies the label image to obtain the identification of the target object. The identification device can also be a barcode scanner, which scans the label of the target object through infrared, radio frequency identification or NFC and other technologies to obtain the identification of the target object.

[0096] After obtaining the identifier of the target object, the processor 20 ends the scanning task of the previous target object. That is, after obtaining the identifier of the target object, if there is a scanning task currently, the processor 20 ends the current scanning task.

[0097] As can be seen, the user only needs to place the mouse into the anesthesia induction box, and the recognition device will automatically fill in the recognized number into the animal ID currently being examined by the ultrasound imaging device. When one mouse is examined and the next mouse is to be examined, the user does not need to manually end the examination and create a new animal. By recognizing that a new mouse has been placed in the induction box and recognizing the new number, the current scanning task is automatically terminated and a new scanning task for the next mouse is created. The recognized new number is then entered into the ultrasound imaging device system as the animal ID of the new mouse. The high degree of automation saves the user's operation time.

[0098] Step 4: The processor 20 creates a new image scanning task for the target object based on the identifier of the target object.

[0099] Step 5: The processor 20 transmits ultrasound to the target tissue of the target object according to the ultrasound parameters associated with the operation sequence information, receives the ultrasound echo, and obtains an ultrasound image frame of the target object based on the ultrasound echo. Specifically, Figure 3 As shown, this step includes the following steps:

[0100] In step 51, the image generation step, the processor 20 controls the ultrasound probe 10 via the transmission control circuit 30 to transmit ultrasound toward the target tissue of the target subject based on ultrasound parameters associated with the target animal type, target examination site, and target section (i.e., the currently used ultrasound parameters are determined by the target animal type, target examination site, and the current target section). The processor 20 also controls the ultrasound probe 10 via the reception control circuit 40 to receive ultrasound echoes, thereby generating a real-time ultrasound image based on the ultrasound echoes. The processor 20 can display the real-time ultrasound image via the human-computer interaction device 70.

[0101] In step 52, the freeze step, the processor 20 receives the freeze instruction and freezes the ultrasound image in response to the instruction. For example, taking the B image of the long-axis four-chamber cardiac view as an example, after adjusting the image, the user can operate the human-computer interaction device 70 to issue a freeze instruction.

[0102] Step 53: Frame selection and image storage. In this step, the user can select the ultrasound image frame, or the ultrasound image frame can be automatically determined. These steps are described below.

[0103] The processor 20 receives an instruction for selecting a frame of ultrasound image from the frozen ultrasound image and, in response to the instruction, saves the selected ultrasound image as the ultrasound image frame of the target section. That is, the user selects a frame of ultrasound image from the frozen ultrasound image as the ultrasound image of the target section and saves it.

[0104] The processor 20 may also perform quality evaluation on each frame of the frozen ultrasound image to obtain a quality index of each frame of the ultrasound image.

[0105] Specifically, processor 20 analyzes the image quality of the ultrasound image frame of the target section to obtain a first indicator for characterizing image quality. The first indicator can be a quality score or a quality level (e.g., low, medium, high, qualified, unqualified, etc.), as long as it reflects the image quality. Image quality refers to the quality of the image itself and can be reflected in parameters such as clarity, resolution, anatomical similarity, signal-to-noise ratio, and mean square error.

[0106] The processor 20 can estimate the first indicator through a deep learning model. Specifically, a first ultrasound image database is constructed in advance, in which each ultrasound image is marked with the image quality of the ultrasound image (first indicator). A first deep learning model is pre-set, such as an EfficientNet model, a MobileNet model, a VGG model, a ResNet model, and an AlexNet model. The first deep learning model is trained using the constructed first ultrasound image database. After the training is completed, a trained first deep learning model is obtained. The processor 20 inputs each frame of the frozen ultrasound image into the trained first deep learning model, and the first deep learning model outputs the image quality (first indicator) of the ultrasound image.

[0107] The processor 20 can also estimate the image quality (first indicator) of the ultrasound image using traditional image quality assessment methods, including one or more of full-reference, no-reference, and partial-reference image quality assessments, subjective image quality assessment methods, and machine learning image quality assessments. The full-reference image quality assessment method provides a standard reference image and then calculates the distance / error (which can be signal-to-noise ratio, mean square error, structural similarity, etc.) between the image to be evaluated (ultrasound image) and the reference image. By analyzing the obtained error / distance, the quality of the image to be evaluated can be obtained. Semi-reference image quality assessment uses only the feature information of the image to be evaluated (ultrasound image). By comparing the key feature information between the reference image and the image to be evaluated, the quality of the image to be evaluated can be obtained. No-reference image quality assessment uses only the features of the ultrasound image itself (variance, image entropy, spatial frequency, contrast, and average gradient) for evaluation, and performs a comprehensive analysis to obtain the image quality of the ultrasound image.

[0108] The processor 20 identifies the anatomical structure in the ultrasound image frame of the target section and obtains a second indicator for characterizing the imaging quality based on the identified anatomical structure. The second indicator can be a quality score value or a quality level (such as low, medium, high, etc.), which can reflect the imaging quality. The imaging quality reflects the correctness of the doctor's operation of the ultrasound probe. Experienced doctors generally produce higher-quality imaging, while inexperienced doctors may need to spend more time to produce relatively good-quality ultrasound images.

[0109] There are many ways for the processor 20 to identify the anatomical structure in the ultrasound image frame of the target section. For example, the processor 20 performs identification through deep learning target detection and image segmentation methods. Specifically, a second ultrasound image database is pre-constructed, in which each ultrasound image is marked with the anatomical structure area corresponding to the target section, specifically marked with: whether the anatomical structure exists, and if so, the location of the anatomical structure. A second deep learning model is pre-set, and the second deep learning model is trained using the constructed second ultrasound image database. After the training is completed, a trained second deep learning model is obtained. The processor 20 inputs the ultrasound image into the second deep learning model, and the second deep learning model will output whether the anatomical structure corresponding to the target section is contained. If contained, the specific location of the anatomical structure will also be output. For another example, the processor 20 uses a machine learning-based target detection method for identification. For another example, the processor 20 uses a machine learning-based image segmentation method for identification.

[0110] The anatomical structures corresponding to each section are pre-set with corresponding weights. After the processor 20 identifies the anatomical structure, it assigns corresponding weights to each anatomical structure identified from the ultrasound image, and sums up each anatomical structure according to the corresponding weight to obtain a second index. Usually, the important anatomical structures of the section have high weights, and the less important anatomical structures have low weights. If the doctor's mapping skills are good, all the anatomical structures corresponding to the section can be obtained. If the mapping skills are not good, fewer anatomical structures will be obtained, and the corresponding quality score value (second index) will be low, or the quality level will be low.

[0111] The processor 20 obtains a quality indicator for characterizing the comprehensive quality based on the first indicator and the second indicator. For example, the first indicator and the second indicator are pre-set with corresponding weights. The processor 20 assigns corresponding weights to the first indicator and the second indicator respectively, such as multiplying the first indicator by the corresponding weight, multiplying the second indicator by the corresponding weight, and summing the first indicator and the second indicator according to the corresponding weights to obtain a quality indicator. Similarly, the quality indicator can be a quality score value or a quality level. If the quality indicator adopts a quality score value, the processor 20 determines whether the quality indicator reaches a preset threshold. If so, it determines that the quality of the ultrasound image meets the standard, otherwise it determines that the quality of the ultrasound image does not meet the standard. If the quality indicator is a quality level, the processor 20 determines whether the quality indicator reaches the preset level. If so, it determines that the quality of the ultrasound image meets the standard, otherwise it determines that the quality of the ultrasound image does not meet the standard.

[0112] The processor 20 may also display the first indicator, the second indicator and / or the quality indicator on the display interface, so that the user can intuitively see the image quality, printing quality and / or comprehensive quality of the ultrasound image.

[0113] The processor 20 can save the ultrasound image with the highest quality index as the ultrasound image frame of the target section, eliminating the need for the user to make a judgment. The processor 20 can also display the ultrasound image with the highest quality index on the display interface for the user to select. The user can select the ultrasound image with the highest quality index or another ultrasound image. That is, the processor 20 receives an instruction for selecting an ultrasound image frame from the frozen ultrasound image and, in response to the instruction, saves the selected ultrasound image as the ultrasound image frame of the target section.

[0114] The processor 20 can also determine whether the quality index is higher than the quality threshold. When the quality index is not higher than the preset quality threshold, the processor 20 outputs a prompt message for prompting that the ultrasound image quality does not meet the standard, for example, the prompt message is displayed through the human-computer interaction device 70, and the options of re-drawing and continuing drawing are provided for the user to select. If the user chooses to re-draw, the processor 20 receives the instruction for re-drawing, responds to the instruction, returns to the drawing step 51 to re-draw the target section, and re-saves the ultrasound image frame of the target section after the freezing step 52 and the frame selection and storage step 53, that is, repeats the process. Figure 3 If the user chooses to continue drawing, the processor 20 receives an instruction to continue drawing and, in response to the instruction, returns to the drawing step 51 to draw the next target section. After the freezing step 52 and the frame selection and storage step 53, the ultrasound image frame of the next target section is saved.

[0115] The operation sequence information may include multiple target sections. After the processor 20 saves the ultrasound image frame of the target section, it returns to the drawing step 51 to draw the next target section. After the freezing step 52 and the frame selection and storage step 53, the ultrasound image frame of the next target section is saved; this cycle is repeated until the ultrasound image frames of all target sections are saved.

[0116] Step 6. The processor 20 measures the ultrasound image frame of the target object to obtain a measurement result. Specifically, when the quality index is higher than a preset quality threshold, the processor 20 measures the ultrasound image frame of the target section to obtain a measurement result. Because the type of the target section and its associated post-processing method are all known, it is also known which target anatomical structure needs to be measured on the ultrasound image frame of the target section, and these can be preset in advance. In the aforementioned steps, the processor 20 has identified the corresponding target anatomical structure from the ultrasound image frame of the target object, so the measurement result can be obtained by measuring the target anatomical structure according to the measurement items pre-associated with the target anatomical structure. When the quality index is not higher than the quality threshold, if the user chooses to continue drawing in the aforementioned step, there is no need to measure the ultrasound image frame whose quality index is not higher than the quality threshold, and the user can perform manual measurement later.

[0117] Taking the heart as an example, the current target section is the long-axis four-chamber section, and the ultrasound image frame is a B-image. After the processor 20 identifies the left atrium, if the quality index is higher than the quality threshold, the LA Diam is measured and the measurement result is stored in the memory 80. The identification of the target anatomical structure, automatic measurement, and measurement results may not be displayed on the interface, that is, they are performed in the background. The processor 20 then automatically switches the image mode from B mode to M mode and adjusts the sampling line interface. If the quality index is not higher than the quality threshold, that is, the image quality does not meet the automatic measurement standard and the LA Diam cannot be identified, a prompt message will pop up to remind the user. The user can choose to redraw the image or choose to perform manual measurement and then continue the examination. The processor 20 automatically switches to M mode to adjust the sampling line interface.

[0118] The user can adjust the M sampling line to the target position and click to start scanning (returning to the drawing step 51). The processor 20 begins scanning the M image through the ultrasound probe 10. After the user sees the desired image, the user freezes it (freeze step 52). After adjusting to the frame of image to be saved, the user clicks to save (frame selection and image storage step 53). The processor 20 identifies the target anatomical structure in the M image, such as the left atrium and left ventricle. If the quality index of the M image is higher than the quality threshold, the processor 20 automatically measures IVSd, LVIDd, LVPWd, IVSs, LVIDs, LVPWs, and automatically calculates LVEDV, LVESV, FS, and EF. The measurement results are stored in the memory 80. The processor 20 then automatically switches to the B image mode of the short-axis main pulmonary artery section and starts the drawing step of the next target section. If the image quality does not meet the automatic measurement standard and the ventricular walls and measurement results at the end of diastole and end of systole cannot be identified, a prompt message will pop up to remind the user. The user can choose to redraw the image or perform manual measurement and then continue the examination. The processor 20 automatically switches to the B image mode of the short-axis main pulmonary artery section.

[0119] For the short-axis main pulmonary artery view, the processor 20 and the user perform Figure 3 Steps shown.

[0120] Afterwards, the processor 20 automatically switches to B+C mode and displays the sampling frame of C mode on the display interface. The user operates the human-computer interaction device 70 to adjust the size and position of the sampling frame to the target area, freezes the image, and adjusts to a frame of image to be saved, then clicks Save. After that, the processor 20 automatically switches to B+C+PW mode to adjust the PW sampling line interface.

[0121] The user adjusts the PW sampling line to the target position and clicks Start Scan. The system begins scanning the PW spectrum. The user freezes the image they want and clicks Save after adjusting to the frame they want to save.

[0122] The processor 20 automatically identifies the atlas and determines whether the atlas's quality index exceeds a quality threshold. If so, it automatically measures the pulmonary artery velocity and saves the measurement results to memory. If ultrasound image frames are obtained for all target sections in the operation sequence information, the display interface may remain at the user's last operation interface. If the atlas's quality index is not above the quality threshold, LA Diam cannot be identified, and a prompt message will pop up to inform the user. The user can choose to re-draw the image or perform a manual measurement later. The processor 20 then remains at the user's last operation interface because the operation sequence information has been completed.

[0123] Step 7. After multiple target objects have obtained measurement results, the processor 20 summarizes the identifiers and measurement results of some or all of the target objects and exports them. For example, after all mice have been examined, the user can operate the human-computer interaction device to issue an instruction for calling out all ultrasound image frames that have not obtained measurement results. After receiving the instruction, the processor 20 responds to the instruction and displays all ultrasound image frames that have not obtained measurement results on the display interface of the human-computer interaction device for the user to manually measure; then, based on the user's measurement operation, the ultrasound image frames that have not obtained measurement results are measured to obtain measurement results. Thus, all measurement data are completed. The instruction for calling out all ultrasound image frames that have not obtained measurement results can be an instruction for ending the experimental inspection process, that is, the user operates the human-computer interaction device to issue an instruction for ending the experimental inspection process. The processor 20 responds to the instruction, ends the experimental inspection process and displays all ultrasound image frames that have not obtained measurement results on the display interface of the human-computer interaction device for the user to manually measure. The processor 20 may also display an export button on the display interface. After the user triggers the export button, the identifiers of all target objects are displayed on the display interface for the user to select. Based on the identifiers of the target objects selected by the user, the processor 20 summarizes the identifiers of the selected target objects and their measurement results and exports them. The summary can be exported to an Excel table or to a user-specified storage path, making it convenient for the user to subsequently summarize and analyze the data. Of course, the processor 20 may also summarize and export the identifiers of some or all target objects and the measurement results to a PC connected to the ultrasonic imaging device. The user can use the post-processing software on the PC to measure the ultrasonic image frames for which no measurement results have been obtained, and then export all the data uniformly on the PC.

[0124] It can be seen that the ultrasonic imaging equipment provided by the present invention can realize automatic recognition of target object identification, automatic creation of new scanning tasks, automatic mapping, automatic measurement and batch export, requiring less manual operation, thereby greatly improving the efficiency of scientific research ultrasonic examinations.
