Description

Technical Field

[0001] This application relates to the field of ultrasonic imaging technology, and more particularly to an ultrasonic imaging method and an ultrasonic imaging device. Background Art

[0002] Currently, most ultrasonic imaging technologies are real-time, which is also one of the main advantages of medical ultrasound. However, for some new advanced functions, there are currently limitations in software and hardware, cost, and objective conditions, and they cannot be presented in a real-time imaging manner. For example, super-resolution contrast imaging technology, high-frame-rate dynamic vector blood flow imaging technology, etc.

[0003] The super-resolution contrast imaging technology usually collects signals of small blood vessels, and the signals are relatively weak. In order to improve the signal-to-noise ratio and the resolution of blood vessels, it is necessary to collect blood flow signals for a period of time for imaging. This period of time usually reaches several seconds or even dozens of seconds, which is not suitable for real-time imaging. In addition, the data volume for a period of time is large, and the signal processing time is also long. Therefore, usually, another non-real-time signal acquisition and imaging method is adopted. This method can be the acquisition-preparation-printing post-processing mode.

[0004] The high-frame-rate dynamic vector blood flow imaging technology can achieve the display of hundreds or even thousands of blood flow images per second nominally, but this method is also not suitable for real-time display. Because the frame rate of the display generally rarely reaches more than a few hundred, and even if it can, for the presentation of hundreds of images per second, the human eye cannot capture so many details, and real-time display has no practical significance. This kind of imaging usually adopts the form of slow playback. For example, for an image of 500 frames per second, it is played at 25 frames per second for 20 seconds. In addition, for this high-frame-rate blood flow imaging mode, the data processing volume is also very large, which is also one of the reasons why it is not suitable for real-time signal processing. Therefore, usually, a non-real-time signal acquisition and imaging method is also adopted. This method can also be the acquisition-preparation-printing post-processing mode.

[0005] In this acquisition-preparation-printing post-processing mode, during the data processing process, if the user performs other operations through buttons, it may enter other modes, resulting in the termination of the current data processing or the failure of the unprocessed data processing. And the user has already finished printing the image. Maybe the user thinks that the corresponding data has been obtained at this time, but the actual data has not been processed completely. Summary of the Invention

[0006] This application is proposed to solve the above problems. According to one aspect of this application, there is provided an ultrasonic imaging method, the method comprising: controlling an ultrasonic probe to emit a first ultrasonic wave towards a target tissue, receiving an echo of the first ultrasonic wave to obtain first ultrasonic echo data; generating a first ultrasonic image based on the first ultrasonic echo data to determine a section position based on the first ultrasonic image, wherein the first ultrasonic image at least includes the tissue structure of the target tissue; in a state where the super-resolution imaging mode is activated, controlling the ultrasonic probe to emit a second ultrasonic wave towards the target tissue injected with a contrast agent, receiving an echo of the second ultrasonic wave to obtain second ultrasonic echo data; performing super-resolution imaging processing according to the second ultrasonic echo data to generate and display a super-resolution image corresponding to the section position, wherein during the super-resolution imaging processing, the super-resolution imaging mode remains activated, and imaging modes other than the super-resolution imaging mode are in a disabled state that cannot respond to activation operations.

[0007] According to another aspect of this application, there is provided an ultrasonic imaging method, the method comprising: controlling an ultrasonic probe to emit a first ultrasonic wave towards a target tissue, receiving an echo of the first ultrasonic wave to obtain first ultrasonic echo data; generating a first ultrasonic image based on the first ultrasonic echo data to determine a section position; performing data acquisition and imaging processing in a state where a second imaging mode is activated; wherein, the data acquisition includes: controlling the ultrasonic probe to emit a second ultrasonic wave towards the target tissue, receiving an echo of the second ultrasonic wave to obtain second ultrasonic echo data; the imaging processing includes: performing imaging processing corresponding to the second imaging mode according to the second ultrasonic echo data to generate and display a second ultrasonic image; wherein, the second imaging mode is an imaging mode in which the duration of the data acquisition is less than the duration of the imaging processing, and wherein during the imaging processing, the second imaging mode remains activated, and imaging modes other than the second imaging mode are in a disabled state that cannot respond to activation operations.

[0008] According to still another aspect of this application, there is provided an ultrasonic imaging device, the device comprising a transmitting and receiving circuit, an ultrasonic probe, a processor and a display, wherein: the transmitting and receiving circuit is configured to control the ultrasonic probe to emit an ultrasonic wave towards a target object, receive an echo of the ultrasonic wave, and obtain ultrasonic echo data from the echo; the processor is configured to control the transmitting and receiving circuit and execute the above method to generate an ultrasonic image; the display is configured to display the ultrasonic image.

[0009] For an imaging mode where the data acquisition duration is less than the imaging processing duration, during the imaging processing of the ultrasonic imaging method and ultrasonic imaging device of the present application, other imaging modes are in a disabled state and cannot respond to activation operations, which can avoid the problem of imaging processing failure caused by entering other imaging modes during the imaging processing.

[0020] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention. It should be understood that the present invention is not limited by the exemplary embodiments described herein. Based on the embodiments of the present invention described herein, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Figure 1 FIG. shows a schematic flowchart of an ultrasonic imaging method 100 according to an embodiment of the present application. As Figure 1 shown, the ultrasonic imaging method 100 may include the following steps:

[0022] In step S110, control the ultrasonic probe to emit a first ultrasonic wave toward the target tissue, and receive the echo of the first ultrasonic wave to obtain first ultrasonic echo data.

[0023] In step S120, generate a first ultrasonic image based on the first ultrasonic echo data to determine a section position based on the first ultrasonic image, where the first ultrasonic image at least includes the tissue structure of the target tissue.

[0024] In step S130, in a state where the super-resolution imaging mode is activated, control the ultrasonic probe to emit a second ultrasonic wave toward the target tissue injected with a contrast agent, and receive the echo of the second ultrasonic wave to obtain second ultrasonic echo data.

[0025] In step S140, perform super-resolution imaging processing according to the second ultrasonic echo data to generate and display a super-resolution image corresponding to the section position, where during the super-resolution imaging processing, the super-resolution imaging mode remains activated, and the imaging modes other than the super-resolution imaging mode are in a disabled state that cannot respond to the activation operation.

[0026] In an embodiment of the present application, controlling the ultrasonic probe to emit a first ultrasonic wave toward the target tissue of the target object is to generate a first ultrasonic image at least including the tissue structure of the target tissue, so as to determine a suitable section position on the tissue image, and then fix the probe to collect data for super-resolution imaging. This process may also be referred to as the acquisition preparation stage.

[0027] Among them, this acquisition preparation stage may be performed in the grayscale imaging mode. At this time, the generated first ultrasonic image is a grayscale image (B image), and a suitable section position can be determined based on this grayscale image.

[0028] Alternatively, the acquisition preparation stage can also be carried out in a conventional contrast imaging mode (the conventional contrast imaging mode can display contrast images in real time as opposed to the super-resolution imaging mode). At this time, the first ultrasound image generated can include a grayscale image and a contrast image generally superimposed on the grayscale image, or only include the contrast image superimposed on the grayscale image. The appropriate section position can be determined based on the grayscale image and / or the contrast image.

[0029] Alternatively, the acquisition preparation stage can also be carried out in the super-resolution imaging mode. At this time, although in the super-resolution imaging mode, data acquisition for super-resolution imaging has not started yet. Instead, in the acquisition preparation stage, real-time imaging can be performed at the frame rate of the conventional contrast imaging mode. The first ultrasound image generated can also include a grayscale image and a contrast image generally superimposed on the grayscale image, or only include the contrast image superimposed on the grayscale image. The appropriate section position can be determined based on the grayscale image and / or the contrast image.

[0030] After determining the section position based on the first ultrasound image, the user fixes the probe. At this time, the super-resolution imaging mode is in an active state, and data acquisition for super-resolution imaging can start, that is, enter the data acquisition stage. In this stage, the ultrasound probe can be controlled to emit a second ultrasonic wave to the target tissue injected with the contrast agent to obtain second ultrasonic echo data. This second ultrasonic echo data is the data used for super-resolution imaging. Generally, the duration of data acquisition is not too long, ranging from several hundred milliseconds to several seconds. In actual clinical scenarios, it generally does not exceed 10 seconds. After the data starts to be acquired, the ultrasound system can perform imaging processing while acquiring data. Since the amount of data acquired is very large and imaging processing (also known as data processing) cannot be performed in real time, the time for plotting and acquiring data will be less than or even much less than the imaging processing time. Based on this, during the relatively long imaging processing period, if the user performs other operations through buttons, keyboards, or voice, etc., it may enter other modes, resulting in the termination of the current imaging processing. If entering other real-time modes, the previous data may be overwritten, resulting in data processing failure.

[0031] Therefore, in the embodiments of the present application, during the super-resolution imaging processing, the super-resolution imaging mode remains in an active state, and imaging modes other than the super-resolution imaging mode are in a disabled state that cannot respond to activation operations. In this way, the problem of imaging processing failure caused by entering other imaging modes during imaging processing can be avoided.

[0032] Specifically, in one embodiment, during the super-resolution imaging processing, the operation buttons on the human-computer interaction device for entering imaging modes other than the super-resolution imaging mode can be made ineffective, thereby implementing the disabled state of imaging modes other than the super-resolution imaging mode that cannot respond to activation operations.

[0033] For example, the human-machine interaction device can be a touch screen, which includes virtual buttons. Generally, clicking on a virtual button can execute the corresponding operation. For example, the touch screen includes a first virtual button for entering the grayscale imaging mode (B mode). Generally, clicking on this button is regarded as an activation operation. Generally, in response to this activation operation, the grayscale imaging mode can be entered. Similarly, the touch screen includes a second virtual button for entering the color imaging mode (C mode). Generally, clicking on this button is regarded as an activation operation. Generally, in response to this activation operation, the color imaging mode can be entered. Similarly, the touch screen can also include virtual buttons for entering other imaging modes (such as super-resolution imaging mode, conventional contrast imaging mode, vector flow imaging mode, etc.). Clicking on them can enter the corresponding imaging modes respectively. Therefore, as described above, during the imaging process in the super-resolution imaging mode, the operation buttons on the touch screen for entering imaging modes other than the super-resolution imaging mode can be disabled (i.e., made ineffective). For example, the virtual buttons become unclickable and gray, so that the user cannot click on them, that is, cannot perform an activation operation on them, and thus cannot enter other imaging modes. That is, the imaging modes other than the super-resolution imaging mode are in a disabled state where they cannot respond to activation operations, thereby avoiding the problem of imaging process failure caused by entering other imaging modes during the imaging process.

[0034] In another embodiment, the human-machine interaction device may be a control panel such as a keyboard, which includes mechanical buttons such as physical buttons or knobs. Generally, pressing a mechanical button can execute a corresponding operation. For example, the control panel includes a first mechanical button for entering the grayscale imaging mode (B mode). Generally, pressing this button is regarded as an activation operation. Generally, in response to this activation operation, it is possible to enter the grayscale imaging mode. Similarly, the control panel includes a second mechanical button for entering the color imaging mode (C mode). Generally, pressing this button is regarded as an activation operation. Generally, in response to this activation operation, it is possible to enter the color imaging mode. Similarly, the control panel may also include mechanical buttons for entering other imaging modes (such as super-resolution imaging mode, conventional contrast imaging mode, vector flow imaging mode, etc.). Pressing them can enter the corresponding imaging modes respectively. Compared with the virtual buttons described above, mechanical buttons generally cannot be directly disabled so that they cannot be pressed. Therefore, during the imaging process in the super-resolution imaging mode, the user operations received by the operation buttons on the control panel for entering imaging modes other than the super-resolution imaging mode can be made invalid, that is, even if a user pressing operation is received, this operation is regarded as invalid and not responded to, so that it will not enter other imaging modes, that is, the imaging modes other than the super-resolution imaging mode are in a disabled state where they cannot respond to the activation operation, thus avoiding the problem that the imaging process fails due to entering other imaging modes during the imaging process.

[0035] In other embodiments, the human-machine interaction device may include a voice input device, such as a microphone, and there may be an implementation method of performing user operations through voice input. In such a case, the voice input function can be disabled during the imaging process; or, instead of disabling the voice input function, the input voice is subjected to voice recognition. When a voice input for entering other imaging modes is recognized, it is regarded as an invalid user operation and not responded to. These two methods are essentially similar to the two methods described above, and can also achieve that during the imaging process in the super-resolution imaging mode, the imaging modes other than the super-resolution imaging mode are in a disabled state where they cannot respond to the activation operation, thus avoiding the problem that the imaging process fails due to entering other imaging modes during the imaging process.

[0036] In an embodiment of the present application, method 100 may further include: outputting a prompt message after obtaining the second ultrasonic echo data; or, outputting a prompt message after reaching a preset acquisition time; wherein, the prompt message is used to prompt that the data acquisition is completed, and the preset acquisition time is the total duration preset for transmitting the second ultrasonic wave. As mentioned above, for super-resolution imaging, since the amount of data collected is very large and imaging processing cannot be performed in real time, the time for taking pictures and collecting data is less than or even much less than the imaging processing time. During the imaging processing, the user may not know that the probe can be removed at this time and still hold the probe on the target object, that is, still taking pictures, resulting in unnecessary operations and easily increasing the user's fatigue level. Therefore, in this embodiment, after obtaining sufficient data for super-resolution imaging or reaching the preset data acquisition duration, it indicates that the data acquisition is completed, and a prompt message can be output to the user to prompt that the data acquisition is completed, so that the user knows that the probe can be removed, avoiding unnecessary operations that cause user fatigue.

[0037] Therefore, as described above, after the super-resolution data acquisition is completed, a prompt message can be output, such as a text prompt, to prompt the user that the data acquisition is completed and the probe can be removed; during the super-resolution imaging processing, the operation buttons on the human-computer interaction device for entering imaging modes other than the super-resolution imaging mode can be disabled to avoid the problem of imaging processing failure caused by entering other imaging modes during the imaging processing. In addition, after the super-resolution imaging processing is completed, the aforementioned prompt message can disappear (or disappear at an earlier time, such as a few seconds after the prompt message is output). At the same time, since the processing is completed, the disabling of the aforementioned buttons can be lifted (that is, the aforementioned disabled state is lifted, making the imaging modes other than the super-resolution imaging mode available states that can respond to activation operations), facilitating the user to perform other operations. Figure 2 That is, the above process is briefly shown, which can be combined with Figure 2 to better understand the content described above.

[0038] In the embodiment described above, during the super-resolution imaging processing, the operation buttons on the human-computer interaction device for entering imaging modes other than the super-resolution imaging mode are invalidated, or the user operations received by the operation buttons are invalidated, so that the imaging modes other than the super-resolution imaging mode are in a disabled state that cannot respond to activation operations. In other embodiments, more operation buttons on the human-computer interaction device, such as all buttons, can also be invalidated, or all user operations received by all buttons can be invalidated. This can not only avoid the problem of imaging processing failure caused by entering other imaging modes during the imaging processing, but also avoid imaging processing failure caused by other incorrect operations.

[0039] In a further embodiment of the present application, during super-resolution imaging processing, at least some operation buttons on the human-computer interaction device (or the user operations received thereby) can be made effective and not disabled to cope with some special and unexpected situations, etc.

[0040] Exemplarily, method 100 may further include: during super-resolution imaging processing, when a first preset button on the human-computer interaction device receives a user operation, interrupt the super-resolution imaging processing.

[0041] For example, in one example, during imaging processing, the user discovers that the printing position is incorrect based on the partially displayed imaging results, that is, the previously selected section position is inaccurate or inappropriate. At this time, although some imaging processing has been performed, subsequent processing is no longer required. Therefore, by operating the first preset button on the human-computer interaction device (such as pressing or clicking the button), the super-resolution imaging processing can be interrupted, and the interruption at this time is actually terminating the imaging processing.

[0042] In another example, during imaging processing, the user pre-sets to collect data for N seconds and the imaging processing obtains M frames of images. However, after processing n seconds of data (n is less than N) to obtain m frames of images (m is less than M), the user discovers that the images at this time are already sufficient for observation. Therefore, by operating the first preset button on the human-computer interaction device (such as pressing or clicking the button), the super-resolution imaging processing can be interrupted, and the interruption at this time is actually terminating the imaging processing.

[0043] In yet another example, during imaging processing, the user discovers that there may be a problem with the printing position based on the partially displayed imaging results. At this time, by operating the first preset button on the human-computer interaction device (such as pressing or clicking the button), the super-resolution imaging processing can be interrupted; but after confirmation, it is found that there is no problem with the printing position. At this time, through other operations (to be described later), the super-resolution imaging processing can be continued. In this example, the aforementioned interruption is actually temporarily suspending the imaging processing.

[0044] Therefore, during super-resolution imaging processing, at least some operation buttons on the human-computer interaction device (or the user operations received thereby) can be made effective and not disabled to be flexibly applied to various scenarios.

[0045] In a further embodiment of the present application, after the aforementioned interrupted super-resolution imaging process, the processed data can be saved. Since after the interrupted super-resolution imaging process, partial imaging processing has been completed previously, at this time, the processed data can be saved. This part of the data may be useful (such as the latter two examples among the aforementioned three examples), so it is necessary to save it. This part of the data may also be useless (such as the first example among the aforementioned three examples), so it can also be determined whether to save the processed data according to the specific situation.

[0046] For example, in one embodiment, method 100 further includes: after the interrupted super-resolution imaging process, when the second preset button on the human-machine interaction device receives a user operation, deleting the processed data; restoring the operation button for entering an imaging mode other than the super-resolution imaging mode from invalid to valid, or restoring the user operation received by the operation button from invalid to valid; controlling the ultrasonic probe to emit a third ultrasonic wave to the target tissue, receiving the echo of the third ultrasonic wave to obtain third ultrasonic echo data, and generating a third ultrasonic image based on the third ultrasonic echo data to determine a new section position, so as to perform super-resolution imaging based on the new section position.

[0047] This embodiment can be applied to the first example among the three examples described above, that is, during the imaging process, the user discovers that the mapping position is incorrect according to the partial imaging results that have been displayed. For this scenario, in the case where the processed data has been saved previously, the processed data can be deleted and a new section position can be determined again, that is, return to the acquisition preparation stage. Since the acquisition preparation stage may need to be carried out in an imaging mode other than the super-resolution imaging mode (such as the grayscale imaging mode or the conventional contrast imaging mode), at this time, the aforementioned disabled state can be lifted, that is, the operation button for entering an imaging mode other than the super-resolution imaging mode is restored from invalid to valid, or the user operation received by the operation button is restored from invalid to valid. Then, ultrasonic waves (referred to as the third ultrasonic wave to distinguish from the first ultrasonic wave in the previous text) can be emitted to the target tissue again to generate an ultrasonic image to re-determine the section position, so as to perform super-resolution imaging based on the new section position.

[0048] In another embodiment, method 100 may further include: after the interrupted super-resolution imaging process, when the third preset button on the human-machine interaction device receives a user operation, continuing the super-resolution imaging process.

[0049] This embodiment can be applied to the third example among the three examples described above, that is, during the imaging process, the user discovers that there may be a problem with the printing position based on the partially displayed imaging results, but after confirmation, it is found that there is no problem with the printing position. For this scenario, in the case where the processed data has been previously saved, the imaging process can be resumed, for example, by a third preset button, to continue the unfinished imaging process.

[0050] The above two embodiments are possible operations after interrupting the imaging process and saving the processed data. Of course, saving the processed data may not require re-determining the section position nor continuing the processing, but rather considering that the saved data is sufficient to meet the user's needs, as described in the second example of the third example among the three examples described above, that is: during the imaging process, the user pre-sets to collect data for N seconds, and the imaging process obtains M frames of images, but after processing n seconds of data (n is less than N) to obtain m frames of images (m is less than M), the user discovers that the images at this time are already sufficient for observation.

[0051] In other embodiments, after interrupting the imaging process, the processed data may not be saved first, but operations may be performed according to subsequent user operations.

[0052] For example, in one embodiment, method 100 may further include: after interrupting the super-resolution imaging process, when a second preset button on the human-computer interaction device receives a user operation, making the operation button for entering an imaging mode other than the super-resolution imaging mode change from invalid to valid, or making the user operation received by the operation button change from invalid to valid; controlling the ultrasonic probe to emit a third ultrasonic wave to the target tissue, receiving the echo of the third ultrasonic wave to obtain third ultrasonic echo data, and generating a third ultrasonic image based on the third ultrasonic echo data to determine a new section position, so as to perform super-resolution imaging based on the new section position.

[0053] This embodiment can be applied to the first example among the three examples described above, that is, during the imaging process, the user discovers that the printing position is incorrect based on the partially displayed imaging results. For this scenario, in the case where the processed data has not been previously saved, a new section position can be re-determined, that is, return to the acquisition preparation stage. Since the acquisition preparation stage may need to be carried out in an imaging mode other than the super-resolution imaging mode (such as the grayscale imaging mode or the conventional contrast imaging mode), at this time, the aforementioned disabled state can be lifted, that is, making the operation button for entering an imaging mode other than the super-resolution imaging mode change from invalid to valid, or making the user operation received by the operation button change from invalid to valid. Then, ultrasonic waves (referred to as the third ultrasonic waves to distinguish them from the first ultrasonic waves above) can be re-emitted to the target tissue to generate an ultrasonic image to re-determine the section position, so as to perform super-resolution imaging based on the new section position.

[0054] In another embodiment, method 100 may further include: after interrupting the super-resolution imaging process, when a third preset button on the human-computer interaction device receives a user operation, saving the processed data and continuing the super-resolution imaging process.

[0055] This embodiment can be applied to the third example among the three examples described above. That is, during the imaging process, the user discovers that there may be a problem with the printing position based on the partially displayed imaging results, but after confirmation, it is found that there is no problem with the printing position. For this scenario, in the case where the processed data has not been saved previously, the processed data can be saved first, and then, for example, through the third preset button, the imaging process can be resumed to continue the unfinished imaging process.

[0056] In the above embodiment, the first preset button can be a freeze button, and the second preset button can be a thaw button. In this way, clicking or pressing the freeze button can interrupt the current imaging process; clicking or pressing the thaw button can restore the operation buttons used to enter imaging modes other than the super-resolution imaging mode from invalid to valid, or restore the user operations received by the operation buttons from invalid to valid, and return to the acquisition preparation stage to re-determine the section position for re-acquiring and imaging the super-resolution imaging data.

[0057] Among them, the first preset button and the second preset button can be different buttons, and the user can operate each of them to achieve the desired purpose. Or, the first preset button and the second preset button can also be the same button. This same button has two states, namely the freeze button state and the thaw button state. Each time the same button receives a user operation, it switches from one state to the other. For example, when the user clicks or presses the button for the first time, it represents a freeze operation; when clicking or pressing the button again, it represents a thaw operation. Clicking the button next time represents a freeze operation again, and so on. Or, the same button performs the operation corresponding to the freeze button or the operation corresponding to the thaw button according to different user operations received. For example, single-clicking or short-pressing the button represents a freeze operation; double-clicking or long-pressing the button represents a thaw operation, and so on.

[0058] The above-mentioned third preset button can be a button different from the first preset button and the second preset button, or it can also be the same button as at least one of the first preset button and the second preset button. Similar to the foregoing description, when it is the same button, different subsequent processes can be achieved by performing different operations on the same button, and no further examples will be described here.

[0059] In an embodiment of the present application, during imaging processing, every time the data capable of generating one frame of super-resolution image is processed, one frame of super-resolution image can be generated and displayed. Alternatively, after all the data is processed, that is, after the imaging processing is completely finished, the super-resolution image can be generated and displayed. In addition, after the super-resolution image is generated, parameter measurement can be performed on the super-resolution image, and the measurement result can be output.

[0060] Therefore, as described above, after the super-resolution data acquisition is completed, a prompt message can be output, such as a text prompt, to prompt the user that the data acquisition is completed and the probe can be removed; during the super-resolution imaging processing, the button for entering other imaging modes can be disabled to avoid the problem that the imaging processing fails due to entering other imaging modes during the imaging processing. In addition, during the super-resolution imaging processing, the freeze and thaw buttons are not disabled. After clicking the freeze button, the data processing can be interrupted. At this time, the text prompt disappears, and the disabled buttons can also be restored. Clicking the freeze button again (when the freeze and thaw buttons are the same button) or clicking the thaw button can return to the acquisition equipment state. In addition, after the data processing is interrupted, a part of the video (i.e., the processed data) can be saved, and this part of the video can be used to perform quantitative measurement operations. Figure 3 That is, the above process is concisely shown, which can be combined with Figure 3 to better understand the foregoing content.

[0061] The above exemplarily shows the ultrasonic imaging method 100 according to an embodiment of the present application. Based on the above description, during the super-resolution imaging processing of the ultrasonic imaging method 100 according to an embodiment of the present application, the super-resolution imaging mode remains in an active state, and the imaging modes other than the super-resolution imaging mode are in a disabled state that cannot respond to the activation operation, which can avoid the problem that the imaging processing fails due to entering other imaging modes during the imaging processing. In addition, after the ultrasonic imaging method 100 according to an embodiment of the present application obtains sufficient data for super-resolution imaging or reaches the preset data acquisition duration, a prompt message can be output to the user to prompt that the data acquisition is completed, avoiding unnecessary operations that cause user fatigue.

[0062] Next, in combination with Figure 4 describe the ultrasonic imaging method according to another embodiment of the present application. As Figure 4 shown, the ultrasonic imaging method 400 may include the following steps:

[0063] In step S410, control the ultrasonic probe to emit a first ultrasonic wave to the target tissue, and receive the echo of the first ultrasonic wave to obtain first ultrasonic echo data.

[0064] In step S420, a first ultrasound image is generated based on the first ultrasound echo data to determine a section position based on the first ultrasound image.

[0065] In step S430, data acquisition is performed in an activated state of a second imaging mode: controlling an ultrasound probe to emit a second ultrasonic wave toward a target tissue, and receiving an echo of the second ultrasonic wave to obtain second ultrasound echo data; wherein the second imaging mode is an imaging mode in which a data acquisition duration is less than an imaging processing duration.

[0066] In step S440, imaging processing is performed in an activated state of the second imaging mode: performing imaging processing corresponding to the second imaging mode according to the second ultrasound echo data to generate and display a second ultrasound image; wherein during the imaging processing, the second imaging mode remains activated, and imaging modes other than the second imaging mode are in a disabled state that cannot respond to an activation operation.

[0067] The ultrasound imaging method 400 according to an embodiment of the present application is generally similar to the ultrasound imaging method 100 described above. The differences are as follows: The ultrasound imaging method 100 is specifically defined for a super-resolution imaging mode; while the ultrasound imaging method 400 is defined for a second imaging mode, wherein the second imaging mode is an imaging mode in which a data acquisition duration is less than an imaging processing duration. The super-resolution imaging mode is an imaging mode in which a data acquisition duration is less than an imaging processing duration. Therefore, the ultrasound imaging method 100 can also be used for other imaging modes in which a data acquisition duration is less than an imaging processing duration, such as a high frame rate vector blood flow imaging mode, a high frame rate color Doppler imaging mode, a super micro blood flow imaging mode, a multi-position pulsed Doppler imaging mode, a pulse wave imaging mode, and the like. Generally, during the imaging processing of the ultrasound imaging method 400 according to an embodiment of the present application, the second imaging mode remains activated, and imaging modes other than the second imaging mode are in a disabled state that cannot respond to an activation operation, which can avoid the problem that the imaging processing fails due to entering other imaging modes during the imaging processing. How to keep the current imaging mode activated and other imaging modes in a disabled state that cannot respond to an activation operation during the imaging processing has been described in detail above. Here, for the sake of brevity, only some main operations are described, and specific details are not elaborated. Those skilled in the art can understand in combination with the above description.

[0068] In an embodiment of the present application, during the imaging processing, an operation button on the human-computer interaction device for entering an imaging mode other than the second imaging mode is invalidated, or a user operation received by the operation button is invalidated, so that imaging modes other than the second imaging mode are in a disabled state that cannot respond to an activation operation.

[0069] In an embodiment of the present application, method 400 may further include: during imaging processing, when a first preset button on the human-machine interaction device receives a user operation, interrupt the imaging processing.

[0070] In an embodiment of the present application, method 400 may further include: after interrupting the imaging processing, save the processed data.

[0071] In an embodiment of the present application, method 400 may further include: after interrupting the imaging processing, when a second preset button on the human-machine interaction device receives a user operation, delete the processed data; restore the operation button for entering an imaging mode other than the second imaging mode from invalid to valid, or restore the user operation received by the operation button from invalid to valid; control the ultrasonic probe to emit a third ultrasonic wave to the target tissue, receive the echo of the third ultrasonic wave to obtain third ultrasonic echo data, and generate a third ultrasonic image based on the third ultrasonic echo data to determine a new section position, so as to perform ultrasonic imaging based on the new section position.

[0072] In an embodiment of the present application, method 400 may further include: after interrupting the imaging processing, when a third preset button on the human-machine interaction device receives a user operation, continue the imaging processing.

[0073] In an embodiment of the present application, method 400 may further include: after interrupting the imaging processing, when a second preset button on the human-machine interaction device receives a user operation, restore the operation button for entering an imaging mode other than the second imaging mode from invalid to valid, or restore the user operation received by the operation button from invalid to valid; control the ultrasonic probe to emit a third ultrasonic wave to the target tissue, receive the echo of the third ultrasonic wave to obtain third ultrasonic echo data, and generate a third ultrasonic image based on the third ultrasonic echo data to determine a new section position, so as to perform ultrasonic imaging based on the new section position.

[0074] In an embodiment of the present application, method 400 may further include: after interrupting the imaging processing, when a third preset button on the human-machine interaction device receives a user operation, save the processed data and continue the imaging processing.

[0075] In an embodiment of the present application, the first preset button is a freeze button, the second preset button is a thaw button, and the first preset button and the second preset button are the same button or different buttons; when the first preset button and the second preset button are the same button: the same button includes two states, namely the freeze button state and the thaw button state, and each time the same button receives a user operation, it switches from one state to the other state; or the same button performs the operation corresponding to the freeze button or the operation corresponding to the thaw button according to different received user operations.

[0076] In an embodiment of the present application, method 400 may further include: outputting a prompt message after acquiring ultrasonic echo data; or outputting a prompt message after reaching a preset acquisition time; wherein, the prompt message is used to prompt that data acquisition is completed, and the preset acquisition time is the total duration preset for transmitting the second ultrasonic wave.

[0077] In an embodiment of the present application, method 400 may further include: after the imaging process is completed, releasing the disabled state to make the imaging modes other than the second imaging mode available states capable of responding to activation operations.

[0078] In an embodiment of the present application, method 400 may further include: after generating the second ultrasonic image, performing parameter measurement based on the second ultrasonic image and outputting the measurement result.

[0079] In an embodiment of the present application, the second imaging mode may include any one of the following: super-resolution contrast imaging mode (i.e., the super-resolution imaging mode in the aforementioned ultrasonic imaging method 100), high-frame-rate vector blood flow imaging mode, high-frame-rate color Doppler imaging mode, ultra-micro blood flow imaging mode, multi-position pulsed Doppler imaging mode, and pulse wave imaging mode. Among them,

[0080] Among them, the super-resolution contrast imaging performed by the super-resolution contrast imaging mode is mainly used to detect microvessels and capillaries. Generally, non-focused wave scanning methods (such as plane wave scanning) and special filtering and microbubble localization tracking techniques can be used, and the amount of data to be processed is relatively large.

[0081] The high-frame-rate vector blood flow imaging performed by the high-frame-rate vector blood flow imaging mode can calculate the magnitude and direction of blood flow velocity. The high-frame-rate vector blood flow imaging can be achieved by using plane wave or divergent wave scanning. In this way, the frame rate can reach 300 frames or even more than a thousand frames per second. The amount of data of plane wave or divergent wave scanning is relatively large, and the processing of blood flow data is time-consuming.

[0082] The high-frame-rate color Doppler imaging performed by the high-frame-rate color Doppler imaging mode generally uses non-focused wave scanning to achieve high-frame-rate color Doppler imaging. Generally, the frame rate reaches several hundred or even more than a thousand frames per second, and the processing of blood flow data is also time-consuming.

[0083] The ultra-micro blood flow imaging performed by the ultra-micro blood flow imaging mode is mainly used to measure low-speed blood flow and is achieved through special wall filtering processing. The amount of blood flow calculation in this way is much larger than that of traditional color Doppler ultrasound.

[0084] Multi-position pulsed Doppler imaging performed in the multi-position pulsed Doppler imaging mode, as the name implies, requires obtaining pulsed Doppler (PW) spectra at multiple positions. Traditional pulsed Doppler imaging only calculates the PW spectrum at one position at a time. Multi-position PW generally uses non-focused emission scans such as plane waves or diverging waves, and the PW spectra at multiple positions can be calculated simultaneously, which also means an increase in the amount of calculation.

[0085] Pulse wave imaging performed in the pulse wave imaging mode is generally used for measuring the pulse wave velocity (PWV), which is an indicator for evaluating arterial stiffness. For accurate measurement of PWV, plane wave scanning is generally used, and the amount of data processing is large.

[0086] Therefore, the above imaging modes are all imaging modes in which the duration of data acquisition is less than or even much less than the duration of imaging processing. During the imaging processing, other imaging modes are in a disabled state and cannot respond to activation operations, which can avoid the problem of imaging processing failure caused by entering other imaging modes during the imaging processing.

[0087] The following takes the high-frame-rate vector blood flow imaging mode as an example to describe the process of parameter measurement after obtaining the imaging result. In the embodiments of the present application, in the high-frame-rate vector blood flow imaging mode, the parameter measurement includes at least one of the following: measurement of vascular wall shear stress, measurement of blood flow velocity in the region of interest, measurement of blood flow volume, measurement of resistance index and velocity ratio.

[0088] Among them, the measurement of vascular wall shear stress may include: obtaining a first user input for specifying the position of the vascular wall to be measured in the ultrasonic image of the blood vessel to be measured; presenting a first auxiliary line and a second auxiliary line perpendicular to each other at the vascular wall position, where the first auxiliary line is parallel or coincident with the trend of the blood vessel at the vascular wall position, and the second auxiliary line points to the inside of the blood vessel to be measured; obtaining the blood flow velocity in the direction parallel to the first auxiliary line and the distance from the vascular wall position to the center of the blood vessel to be measured in the direction of the second auxiliary line; calculating the shear stress at the vascular wall position based on the blood flow velocity and the distance. The following will be described in conjunction with Figure 5 and Figure 6 to describe.

[0089] As Figure 5As shown, the position of the blood vessel segment to be measured can be found on the generated image / video, and the position 510 of the blood vessel wall to be measured is set. After the selected position, a first auxiliary line x and a second auxiliary line y perpendicular to each other are presented at this position. Generally, the first auxiliary line x is parallel or coincident with the blood vessel trend at the blood vessel wall position 510, and the second auxiliary line y points to the inside of the blood vessel to be measured. If the first and second auxiliary lines do not meet this condition, they can be automatically and / or manually adjusted by the user to meet this condition. Then, the blood flow velocity in the direction parallel to the first auxiliary line and the distance from the blood vessel wall position to the center of the blood vessel to be measured in the direction of the second auxiliary line are obtained; the wall shear stress (abbreviated as WSS) of the blood vessel wall position is calculated based on the blood flow velocity and this distance. Among them, the WSS calculation formula can be as follows:

[0090]

[0091] In the above formula, μ is the blood viscosity coefficient, v is the velocity component parallel to the tangent direction of the measurement position (i.e., the direction of the first auxiliary line) (such as Figure 6 shown), r is the normal direction along this tangent, and the distance from the measurement point (i.e., the measurement position 510) to the center of the blood vessel. The wall in the formula indicates that the measurement position of the shear stress is on the blood vessel wall.

[0092] In an embodiment of the present application, the measurement of the blood flow velocity in the region of interest (ROI) may include: obtaining a second user input for specifying the size and position of the region of interest in the blood vessel to be measured in the ultrasonic image; calculating at least one of the maximum value, average value, and median value of the blood flow velocity in the region of interest. The following will be described in conjunction with Figure 7 to describe.

[0093] As Figure 7 shown, the position of the blood vessel segment to be measured can be found on the generated image / video, and the size and position of the ROI box are manually set within the blood vessel segment; the relevant results in the ROI box are calculated, such as the maximum value, minimum value, average value, median value, etc. of the blood flow velocity in the ROI box, and the relevant results are displayed.

[0094] In an embodiment of the present application, the measurement of the blood flow volume may include: obtaining a third user input for setting the position of the diameter of the blood vessel to be measured in the ultrasonic image; obtaining the blood flow velocity in the direction perpendicular to the diameter, and calculating the blood flow volume based on the blood flow velocity. The following will be described in conjunction with Figure 8 to describe.

[0095] As Figure 8As shown, the position of the blood vessel segment to be measured can be found on the generated image / video; according to the blood vessel trend, the blood vessel diameter can be manually set; based on the velocity measurement on the diameter, the blood flow rate can be calculated. Among them, the blood flow rate is calculated based on the velocity component and the diameter, and the velocity component is calculated from the vector velocity according to the relevant angle. As Figure 8 shown, is the vector velocity, which is measured by the vector blood flow imaging technique; according to the vector velocity, the velocity component v is obtained along the vertical direction of the manually set diameter; the blood flow rate is calculated according to the velocity component v on the diameter. After calculating the blood flow rate, the calculation result can be displayed.

[0096] In the embodiments of the present application, the measurement of the resistance index and the velocity ratio may include: obtaining a fourth user input, where the fourth user input is used to specify at least two positions to be measured in the blood vessel to be measured in the ultrasonic image; for two different positions to be measured, calculating the blood flow velocity ratio; for one position to be measured, calculating the blood flow velocity ratio at two different times; calculating the resistance index based on the peak systolic blood flow velocity and the end-diastolic blood flow velocity of the blood vessel to be measured. The following will be described in conjunction with Figure 9 and Table 1.

[0097] As Figure 9 shown, the position of the blood vessel segment to be measured can be found on the generated image / video; for two different positions 1+ and 2+ in space, their blood flow velocity ratio can be calculated; for the same position in space (i.e., the position of the velocity curve), the velocity ratio and the resistance index (Resistance Index, abbreviated as RI) are calculated at different times 1x and 2x, and the calculation results are displayed. Among them, the calculation formula of the resistance index is as follows:

[0098]

[0099] In the formula, v PS is the peak systolic flow velocity, and v ED is the end-diastolic flow velocity. Therefore, only the velocity ratio (where the unit of velocity is cm / s) is calculated for the two positions marked with a plus sign "+" in Table 1, and there is no resistance index value.
