Description

Technical Field

[0001] This application relates to the field of ultrasonic technology, and in particular to a method for displaying acoustic attenuation, a method for displaying ultrasonic parameters, and a device. Background Technology

[0002] Ultrasound scanning is a commonly used clinical examination method. By scanning the target tissue of a target object with ultrasound, various parameters of the target tissue can be obtained, such as sound attenuation parameters, elastic parameters, viscoelastic parameters, etc. Medical staff can make clinical diagnoses based on the obtained parameters.

[0003] In clinical ultrasound examinations, multiple measurements are typically performed, and then statistical analysis is conducted on the parameters obtained from these multiple measurements to arrive at a final diagnostic result, thus avoiding the influence of fluctuations in a single measurement on the diagnostic outcome. Therefore, users need to filter out abnormal results from the multiple measurements. However, in related technologies, ultrasound equipment generally displays the results of multiple measurements in the form of report pages or data tables, making it difficult for users to intuitively find and filter out abnormal results from the data tables. Summary of the Invention

[0011] In response to a deletion instruction for at least one frame of the abnormal sound attenuation parameter, only the remaining sound attenuation parameters after deletion in multiple frames of sound attenuation parameters are displayed, or the abnormal sound attenuation parameters deleted in multiple frames of sound attenuation parameters are displayed in a weakened manner.

[0012] A second aspect of this application provides a method for displaying ultrasound parameters, comprising:

[0013] The interface displays an interface for selecting at least two ultrasound scanning modes, which are used to acquire at least two ultrasound parameters of a target area of ​​a target tissue. The at least two ultrasound scanning modes include a first ultrasound scanning mode and a second ultrasound scanning mode.

[0018] Delete at least one frame of the first abnormal ultrasound parameter, and / or delete at least one frame of the second abnormal ultrasound parameter.

[0019] A third aspect of this application provides an ultrasonic device, comprising:

[0021] A processor for performing the method provided in either the first or second aspect of this application;

[0022] A display is used to show the results of the processor's processing.

[0023] The beneficial effects of this solution are as follows: after displaying multiple frames of acoustic attenuation parameters, at least one frame of abnormal acoustic attenuation parameters is identified and an abnormal prompt is given for at least one frame of abnormal acoustic attenuation parameters. This allows users to intuitively see the abnormal acoustic attenuation parameters through the abnormal prompts and trigger a deletion command to delete at least one frame of abnormal acoustic attenuation parameters.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] This application provides a method for displaying sound attenuation; please refer to [link to relevant documentation]. Figure 1 Here is a flowchart of the method, which may include the following steps.

[0037] S101 displays an interface for selecting at least one acoustic attenuation scan mode, which is used to obtain multi-frame acoustic attenuation parameters of the target area of ​​the target tissue.

[0038] S102, in response to the command to select the sound attenuation scanning mode, scans the target tissue based on the sound attenuation scanning mode to obtain multi-frame sound attenuation parameters of the target area.

[0039] S103 displays multi-frame sound attenuation parameters.

[0040] S104, determine at least one frame of abnormal sound attenuation parameters from the multi-frame sound attenuation parameters.

[0041] S105, provide an abnormal alert for at least one frame of abnormal sound attenuation parameters.

[0042] S106, in response to the deletion instruction for at least one frame of abnormal sound attenuation parameters, only the sound attenuation parameters remaining after deletion in the multi-frame sound attenuation parameters are displayed, or the abnormal sound attenuation parameters deleted in the multi-frame sound attenuation parameters are displayed in a weakened manner.

[0043] The beneficial effect of this embodiment is that after displaying multiple frames of acoustic attenuation parameters, at least one frame of abnormal acoustic attenuation parameters is identified and an abnormal prompt is given for at least one frame of abnormal acoustic attenuation parameters. This allows the user to intuitively see the abnormal acoustic attenuation parameters through the abnormal prompt and trigger a deletion command to delete at least one frame of abnormal acoustic attenuation parameters. Thus, this solution can help the user intuitively find and remove abnormal acoustic attenuation parameters, improving the convenience of the user in performing ultrasound scans.

[0044] The display method provided in this embodiment can be performed by any ultrasound device.

[0045] The ultrasound device can display an interface for selecting the ultrasound scanning mode after startup. This interface can display several ultrasound scanning modes supported by the ultrasound device, such as the acoustic attenuation scanning mode.

[0046] The interface for selecting ultrasound scanning modes can display each ultrasound scanning mode in various ways. For example, the interface can display an icon corresponding to each ultrasound scanning mode, or it can display the options corresponding to each ultrasound scanning mode.

[0047] After the interface for selecting the ultrasonic scanning mode is established, the ultrasonic device can obtain the selection instruction for the acoustic attenuation scanning mode based on the operation of the acoustic attenuation scanning mode displayed in the user selection interface. Then, in response to the selection instruction for the acoustic attenuation scanning mode, step S102 is executed to obtain multi-frame acoustic attenuation parameters of the target area. The multi-frame acoustic attenuation parameters represent the acoustic attenuation parameters corresponding to each frame of acoustic attenuation image data / image. It can be the acoustic attenuation parameters corresponding to the entire frame of acoustic attenuation image data / image, or it can be the acoustic attenuation parameters corresponding to a local area of ​​the entire frame of acoustic attenuation image data / image.

[0048] The target area can be any pre-specified region within the target tissue of the object being scanned by ultrasound.

[0049] When acquiring multi-frame acoustic attenuation parameters, ultrasound equipment can first determine the target region on the ultrasound image and / or acoustic attenuation image, and then obtain the multi-frame acoustic attenuation parameters of the target region from the multi-frame acoustic attenuation images obtained from scanning the target tissue.

[0050] In this process, if a target area is identified on an ultrasound image, the ultrasound device can scan the target tissue to obtain a frame of ultrasound image of the target tissue, and then display the frame of ultrasound image. The target area is determined based on the user's operation of identifying the target area on the frame of ultrasound image. The target area can be the entire area or a part of the ultrasound image.

[0051] If a target region is identified on an acoustic attenuation image, the ultrasound device can scan the target tissue to obtain an acoustic attenuation image of the target tissue, and then display that frame of acoustic attenuation image. The target region is determined based on the user's operation of identifying the target region on that frame of acoustic attenuation image. The target region can be the entire region or a part of the acoustic attenuation image.

[0052] If a target region is determined on the acoustic attenuation image, the ultrasound equipment can directly obtain the acoustic attenuation parameters of each frame of the subsequent acoustic attenuation image based on the target region. If a target region is determined on the ultrasound head, the ultrasound equipment can first project the target region determined on the ultrasound image onto the acoustic attenuation image based on the mapping relationship between the ultrasound image and the acoustic attenuation image, and then obtain the acoustic attenuation parameters of each frame of the acoustic attenuation image based on the target region projected onto the acoustic attenuation image.

[0053] In step S102, the ultrasound device can continuously emit ultrasound waves to the target tissue at certain time intervals in the acoustic attenuation scanning mode. Based on the ultrasound echoes formed by the reflection of ultrasound waves by the target tissue, the corresponding ultrasound echo data is obtained. For each frame of ultrasound echo data obtained, the ultrasound device can obtain a frame of acoustic attenuation image of the target tissue based on that frame of ultrasound echo data, and then obtain the acoustic attenuation parameters corresponding to the target area in that frame of acoustic attenuation image. Thus, the ultrasound device can obtain multiple frames of acoustic attenuation parameters of the target area based on multiple frames of acoustic attenuation images obtained by continuous scanning.

[0054] For example, in response to a command to select an acoustic attenuation scanning mode, the ultrasound device scans the target tissue to obtain a first frame acoustic attenuation image of the target tissue, and then obtains the first frame acoustic attenuation parameters corresponding to the target region in the first frame acoustic attenuation image. The device then scans the target tissue to obtain a second frame acoustic attenuation image of the target tissue, and then obtains the second frame acoustic attenuation parameters corresponding to the target region in the second frame acoustic attenuation image. The device then scans the target tissue to obtain a third frame acoustic attenuation image of the target tissue, and then obtains the third frame acoustic attenuation parameters corresponding to the target region in the third frame acoustic attenuation image, and so on.

[0055] A single frame of an acoustic attenuation image contains multiple pixels that can correspond to multiple locations within a target tissue, and the pixel value at each location can represent the acoustic attenuation measurement at that location. The acoustic attenuation parameter of the target region in a single frame of an acoustic attenuation image can be a statistical index of the acoustic attenuation measurements corresponding to multiple pixels within the target region. This statistical index can be any one of various indices such as mean, median, standard deviation, or quartiles.

[0056] Taking the mean as an example of a statistical indicator, after obtaining a frame of acoustic attenuation image, the ultrasound device can obtain the acoustic attenuation measurement value corresponding to each pixel in the target area of ​​the frame of acoustic attenuation image, calculate the average, maximum, minimum or variance of these acoustic attenuation measurements, and determine the calculation result as the acoustic attenuation parameter corresponding to the target area in the frame of acoustic attenuation image. For example, the maximum or minimum or average or variance of the acoustic attenuation of multiple pixels in the target area can be used as the acoustic attenuation parameter of the target area.

[0057] In step S103, the multi-frame sound attenuation parameters can be displayed in various ways.

[0058] One alternative display method is that the ultrasound device displays a data table on the display interface, with each cell of the data table displaying a frame of sound attenuation parameters.

[0059] One optional display method is for the ultrasound device to display multiple frames of acoustic attenuation parameters according to a coordinate axis, where the horizontal axis represents time or frame number, and the vertical axis represents a preset range of acoustic attenuation parameters. In the coordinate axis display, the multiple frames of acoustic attenuation parameters can also be displayed in a preset icon arrangement.

[0060] Please see Figure 2 (1) The preset icon can be a dotted icon. The horizontal axis of each point corresponds to the time or frame number, and the vertical axis represents the value of the sound attenuation parameter of that frame. Taking the sound attenuation parameter as the average sound attenuation of the target area as an example, for example, point P1 in the figure represents the sound attenuation parameter of the first frame obtained by scanning, and its value can be 0.6. Point P2 represents the sound attenuation parameter of the second frame obtained by scanning, and its value can be 0.8.

[0061] Please see Figure 2 (2) The preset icon can be a bar icon. The horizontal axis of each bar icon corresponds to the time or frame number. The height of the bar icon represents the value of the sound attenuation parameter of that frame. For example, the bar icon M1 in the figure represents the sound attenuation parameter of the first frame obtained by scanning, and its value can be 0.7. Point P2 represents the sound attenuation parameter of the 11th frame obtained by scanning, and its value can be 0.8.

[0062] exist Figure 2 In the example, the sound attenuation parameter of a frame can be the average of the sound attenuation measurements of multiple pixels in the target area of ​​the corresponding frame of sound attenuation image, that is, the average sound attenuation value.

[0063] In step S103, the ultrasound device can display all the obtained multiple frames of acoustic attenuation parameters sequentially according to the scanning order. That is, the ultrasound device can display every frame of acoustic attenuation parameters obtained from the start of the scan on the display, and after each subsequent scan, it will display that frame of acoustic attenuation parameters on the display.

[0064] In step S103, the ultrasound device may also select a portion of the acoustic attenuation parameters from the obtained multi-frame acoustic attenuation parameters for display.

[0065] by Figure 2 (2) is an example. The ultrasound device has accumulated 15 frames of acoustic attenuation parameters based on the acoustic attenuation scanning mode. When displaying multiple frames of acoustic attenuation parameters, the ultrasound device can select the acoustic attenuation parameters from frame 1 to frame 5 and from frame 11 to frame 15 to display them in the coordinate axis as bar icons. The acoustic attenuation parameters from frame 6 to frame 10 are not displayed.

[0066] The ultrasound device can select and display multiple frames of acoustic attenuation parameters chosen by the user based on their selection. Alternatively, the ultrasound device can automatically select and display a subset of acoustic attenuation parameters based on a certain pattern; for example, it can remove the first 10 frames of acoustic attenuation parameters obtained at the start of the scan and begin displaying from the 11th frame. The selection method in this embodiment is not limited.

[0067] In some alternative embodiments, the ultrasound device may also simultaneously display ultrasound images and / or acoustic attenuation images on an interface that displays multiple frames of acoustic attenuation parameters.

[0068] For example, an ultrasound device can acquire an ultrasound image of the target tissue based on a frame of ultrasound echo data of the target tissue, and then display the ultrasound image of the target tissue and multiple frames of acoustic attenuation parameters on the screen.

[0069] Furthermore, the ultrasound device can respond to the user's operation of defining a region of interest (ROI) on the ultrasound image, define the ROI on the ultrasound image, and then acquire an acoustic attenuation image of the ROI based on the ultrasound echo data within the ROI, and display the acoustic attenuation image of that frame along with multiple frames of acoustic attenuation parameters.

[0070] The ultrasound device can execute step S104 based on a variety of triggering conditions.

[0071] First, the ultrasound equipment can determine in real time at certain time intervals whether there are abnormal sound attenuation parameters in the multi-frame sound attenuation parameters while displaying multiple frames of sound attenuation parameters. If it is determined that there is at least one frame of abnormal sound attenuation parameters, then step S105 is executed.

[0072] Second, the ultrasound device can also execute step S104 in response to the user's trigger operation. For example, a virtual button for triggering the filtering of abnormal acoustic attenuation parameters can be displayed in the interface displaying multiple frames of acoustic attenuation parameters. The ultrasound device can determine at least one frame of abnormal acoustic attenuation parameters in response to the user's trigger operation on the virtual button.

[0073] Third, the ultrasonic equipment can determine at least one abnormal sound attenuation parameter among the multiple frames of sound attenuation parameters, provided that the multi-frame sound attenuation parameters meet the target conditions.

[0074] When step S104 is triggered in the third manner described above, the ultrasound device can also perform the following steps after obtaining multiple frames of acoustic attenuation parameters through scanning:

[0075] The statistical analysis parameters corresponding to the multi-frame sound attenuation parameters are determined. The statistical analysis parameters corresponding to the multi-frame sound attenuation parameters include at least one of the first statistical analysis parameter and the second statistical analysis parameter. The first statistical analysis parameter includes at least one of the median, interquartile range, mean, and standard deviation. The second statistical analysis parameter includes the ratio or difference of at least two of the median, interquartile range, mean, and standard deviation.

[0076] In this embodiment, the multi-frame acoustic attenuation parameters used to determine the statistical analysis parameters may include the acoustic attenuation parameters of each frame obtained by the ultrasonic device from the start of the scanning based on the acoustic attenuation scanning mode to the present, or may only include the multi-frame acoustic attenuation parameters displayed by the ultrasonic device on the screen.

[0077] Combination Figure 2 Example of (2), multi-frame acoustic attenuation parameters used to determine statistical analysis parameters, may include acoustic attenuation parameters of frames 1 to 15 obtained from the start of scanning based on the acoustic attenuation scanning mode of the ultrasound device, or may only include acoustic attenuation parameters of frames 1 to 5 and frames 11 to 15 displayed on the screen.

[0078] Optionally, when continuously scanning based on the acoustic attenuation scanning mode, the ultrasound device can determine the statistical analysis parameters based on the multiple frames of acoustic attenuation parameters obtained so far for each frame of acoustic attenuation parameters obtained. That is, the ultrasound device can update the corresponding statistical analysis parameters in real time based on the acoustic attenuation parameters obtained in real time during the continuous scanning process.

[0079] Furthermore, given the statistical analysis parameters corresponding to the multi-frame acoustic attenuation parameters, the ultrasound equipment can display both the obtained statistical analysis parameters and the multi-frame acoustic attenuation parameters on the screen in real time.

[0080] Optionally, when statistical analysis parameters are obtained, the ultrasound device can determine in real time whether there are any abnormalities in the currently obtained statistical analysis parameters. If there are abnormalities, the ultrasound device can provide a prompt for the abnormal statistical analysis parameters.

[0081] For example, if at least one of the first statistical analysis parameter and the second statistical analysis parameter is abnormal, an abnormality prompt will be given for at least one of the first statistical analysis parameter and the second statistical analysis parameter that is abnormal.

[0082] One way to provide anomaly alerts for statistical analysis parameters is to display the abnormal parameters and the non-abnormal parameters differently on the screen. For example, abnormal parameters could be displayed in red, while non-abnormal parameters could be displayed in green. Another example is to display a red rectangular border around abnormal parameters, while leaving the border blank around non-abnormal parameters.

[0083] For example, please see Figure 3 , Figure 3 The ratio of standard deviation to mean (STD / Avg) is a second statistical analysis parameter displayed by the ultrasound equipment. If this second statistical analysis parameter is abnormal, the ultrasound equipment displays a red rectangular border around it to indicate the abnormality.

[0084] One way to provide an anomaly alert for abnormal statistical analysis parameters is to output a voice prompt indicating that the corresponding statistical analysis parameter is abnormal. For example, the second statistical analysis parameter could be the ratio of the median to the mean. If the second statistical analysis parameter is abnormal, a voice prompt could be output stating, "The ratio of the median to the mean of the current multi-frame sound attenuation parameters is abnormal."

[0085] In some optional embodiments, the ultrasound device can delete the acoustic attenuation parameters specified by the deletion command from the multi-frame acoustic attenuation parameters after each response to a deletion command. Then, it can update and display the updated statistical analysis parameters based on the deleted acoustic attenuation parameters. For example, the ultrasound device can determine and display a first statistical analysis parameter and a second statistical analysis parameter based on the acoustic attenuation parameters of frames 1 to 15 obtained from the scan. When the ultrasound device receives a deletion command to delete the acoustic attenuation parameters of frames 4 and 5, it can delete the acoustic attenuation parameters of frames 4 and 5, and obtain and display new first and second statistical analysis parameters based on the acoustic attenuation parameters of frames 1 to 3 and frames 6 to 15.

[0086] In other words, after the ultrasound equipment deletes the corresponding acoustic attenuation parameter from the multi-frame acoustic attenuation parameters based on the deletion command, it can perform statistical analysis on the remaining acoustic attenuation parameters after deletion, obtain the statistical analysis parameters of the remaining acoustic attenuation parameters, and update the display.

[0087] Anomalies in statistical analysis parameters can include statistical analysis parameters being greater than a specific first threshold or being less than a specific second threshold.

[0088] For example, the first statistical analysis parameter can be the median of the sound attenuation parameters of multiple frames. If the median is greater than the first threshold corresponding to the median, or less than the second threshold corresponding to the median, it can be determined that the first statistical analysis parameter is abnormal.

[0089] The thresholds for different statistical analysis parameters can be the same or different. The thresholds for each statistical analysis parameter can be set manually by the user, configured by the ultrasound equipment based on the system parameters by default, or determined by the ultrasound equipment based on one or more physiological parameters of the target object being scanned.

[0090] Based on the obtained statistical analysis parameters, the ultrasound device can determine whether these statistical analysis parameters are abnormal. If at least one statistical analysis parameter is abnormal, it can be determined that the multi-frame acoustic attenuation parameters meet the target conditions. Then, S104 can be executed to determine the abnormal acoustic attenuation parameters.

[0091] Specifically, when the statistical analysis parameters include a first statistical analysis parameter and a second statistical analysis parameter, the ultrasound device may perform at least one of the following steps when executing S104:

[0092] If at least one of the first statistical analysis parameters is abnormal, at least one abnormal sound attenuation parameter is determined from the multi-frame sound attenuation parameters.

[0093] If at least one of the second statistical analysis parameters is abnormal, at least one abnormal sound attenuation parameter is determined from the multi-frame sound attenuation parameters.

[0094] There are several ways to determine the attenuation parameters of abnormal sound.

[0095] One possible method is for the ultrasound device to compare multiple frames of acoustic attenuation parameters with a preset acoustic attenuation parameter threshold, and determine at least one frame of abnormal acoustic attenuation parameters based on the comparison results. For example, if a frame of acoustic attenuation parameters is greater than the acoustic attenuation parameter threshold, then the frame of acoustic attenuation parameters is determined to be an abnormal acoustic attenuation parameter.

[0096] One possible method is to compare the sound attenuation parameters of multiple frames with at least one first statistical analysis parameter, and determine at least one frame of abnormal sound attenuation parameters based on the comparison results.

[0097] In the second determination method, when the ultrasonic device performs S104, it may specifically perform at least one of the following steps:

[0098] If at least one of the first statistical analysis parameters is abnormal, the sound attenuation parameters of multiple frames are compared with at least one of the first statistical analysis parameters, and at least one abnormal sound attenuation parameter is determined based on the comparison results.

[0099] If at least one of the second statistical analysis parameters is abnormal, the sound attenuation parameters of multiple frames are compared with at least one of the first statistical analysis parameters, and at least one abnormal sound attenuation parameter is determined based on the comparison results.

[0100] The method of comparing the multi-frame sound attenuation parameters with the first statistical analysis parameter to determine the abnormal sound attenuation parameter can be to subtract the multi-frame sound attenuation parameters from at least one first statistical analysis parameter, and determine the sound attenuation parameter of at least one frame with a difference greater than a first threshold as the abnormal sound attenuation parameter.

[0101] Another way to determine abnormal sound attenuation parameters is to compare multiple frames of sound attenuation parameters with the first statistical analysis parameter, and determine the sound attenuation parameter of at least one frame with a ratio greater than the second threshold as the abnormal sound attenuation parameter.

[0102] The first statistical analysis parameter used for comparison can be correlated with the second statistical analysis parameter that shows anomalies.

[0103] In some embodiments, the second statistical analysis parameter may include the ratio of the interquartile range to the median, or the ratio of the standard deviation to the mean. The first threshold may include a first sub-threshold and a second sub-threshold.

[0104] If the ratio of the interquartile range to the median is abnormal, the ultrasound equipment can determine that the median of the multi-frame acoustic attenuation parameters is the first statistical analysis parameter for comparison. The multi-frame acoustic attenuation parameters are subtracted from the median, and at least one frame acoustic attenuation parameter whose difference is greater than the first sub-threshold is determined as an abnormal acoustic attenuation parameter.

[0105] If the ratio of the standard deviation to the mean is abnormal, the ultrasound equipment can determine that the mean of the multi-frame acoustic attenuation parameters is the first statistical analysis parameter for comparison. The multi-frame acoustic attenuation parameters are subtracted from the mean, and at least one frame acoustic attenuation parameter whose difference is greater than the second sub-threshold is determined as an abnormal acoustic attenuation parameter.

[0106] In some embodiments, the second statistical analysis parameter may include the ratio of the interquartile range to the median, or the ratio of the standard deviation to the mean. The second threshold may include a third sub-threshold and a fourth sub-threshold.

[0107] If the ratio of the interquartile range to the median is abnormal, the ultrasound equipment can determine that the median of the multi-frame acoustic attenuation parameters is the first statistical analysis parameter for comparison. The multi-frame acoustic attenuation parameters are compared with the median, and at least one frame acoustic attenuation parameter with a ratio greater than the third sub-threshold is determined as an abnormal acoustic attenuation parameter.

[0108] If the ratio of the standard deviation to the mean is abnormal, the ultrasound equipment can determine that the mean of the multi-frame acoustic attenuation parameters is the first statistical analysis parameter for comparison. The multi-frame acoustic attenuation parameters are compared with this mean, and at least one frame acoustic attenuation parameter whose ratio is greater than the fourth sub-threshold is determined as an abnormal acoustic attenuation parameter.

[0109] In step S105, the ultrasound device can provide an abnormal prompt for at least one frame of abnormal sound attenuation parameters in a variety of ways. Specifically, the ultrasound device can provide an abnormal prompt for at least one frame of abnormal sound attenuation parameters in at least one way, using color, icon, shape and sound.

[0110] One way to use color to indicate anomalies is to distinguish between abnormal and non-abnormal sound attenuation parameters in the displayed multi-frame sound attenuation parameters using different colors. Figure 3 For example, in (1), the bar charts of abnormal sound attenuation parameters can be displayed in red and orange (for example, a large abnormal deviation is represented by red, and an abnormal deviation is generally represented by orange), while the bar charts of non-abnormal sound attenuation parameters can be displayed in green.

[0111] One way to indicate anomalies using icons is to display icons marking abnormal sound attenuation parameters within the displayed multi-frame sound attenuation parameters. Figure 3 For example, in (2), the ultrasound device can display a triangle icon (white inverted triangle icon) above the bar chart of the abnormal acoustic attenuation parameters to indicate that these acoustic attenuation parameters belong to the abnormal acoustic attenuation parameters.

[0112] One way to indicate anomalies using shapes is to distinguish between abnormal and non-abnormal sound attenuation parameters using icons of different shapes. Figure 3 For example, in (3), the ultrasound device can display abnormal acoustic attenuation parameters with discontinuous bar charts and non-abnormal acoustic attenuation parameters with continuous bar charts.

[0113] One way to provide abnormal alerts via sound is for the ultrasound equipment to output a prompt voice indicating which acoustic attenuation parameters are abnormal. For example, the ultrasound equipment could output the prompt voice "The acoustic attenuation parameters in the 4th and 5th frames obtained in the current scan are abnormal."

[0114] Non-abnormal sound attenuation parameters refer to those sound attenuation parameters in a multi-frame sound attenuation parameter set that have not been identified as abnormal sound attenuation parameters. For example, if the sound attenuation parameters in frames 4 and 5 of frames 1 to 15 are identified as abnormal sound attenuation parameters, then the non-abnormal sound attenuation parameters can include the sound attenuation parameters in frames 1 to 3, as well as the sound attenuation parameters in frames 6 to 15.

[0115] In some alternative embodiments, the ultrasound device can further distinguish and display different abnormal acoustic attenuation parameters.

[0116] Optionally, the ultrasound equipment can use different colors to distinguish and display different abnormal sound attenuation parameters. Figure 3 Taking (1) as an example, the ultrasound device can display the abnormal sound attenuation parameters with larger deviations from the first statistical analysis parameter in red and the abnormal sound attenuation parameters with smaller deviations from the first statistical analysis parameter in orange, based on the comparison results.

[0117] Optionally, the ultrasound equipment can distinguish and display different abnormal acoustic attenuation parameters using icons of different shapes. Figure 3 For example, in (4), the ultrasound device can display a triangle mark above the bar chart of abnormal sound attenuation parameters with a larger deviation from the first statistical analysis parameter, and a circle mark above the bar chart of abnormal sound attenuation parameters with a smaller deviation from the first statistical analysis parameter, based on the comparison results.

[0118] Based on different primary statistical analysis parameters and different comparison results, abnormal sound attenuation parameters with large deviations and those with small deviations can be distinguished in the following ways.

[0119] First, if the first statistical analysis parameter is the median of the sound attenuation parameters of multiple frames, and the comparison result is the difference between the sound attenuation parameter and the median, then at least one frame of sound attenuation parameter with a difference greater than the first sub-threshold can be identified as an abnormal sound attenuation parameter. Among them, the abnormal sound attenuation parameter with a difference greater than the preset first abnormal threshold belongs to the abnormal sound attenuation parameter with a larger deviation relative to the first statistical analysis parameter, and the abnormal sound attenuation parameter with a difference less than or equal to the first abnormal threshold belongs to the abnormal sound attenuation parameter with a smaller deviation relative to the first statistical analysis parameter.

[0120] Second, if the first statistical analysis parameter is the average value of the sound attenuation parameters of multiple frames, and the comparison result is the difference between the sound attenuation parameter and the average value, then at least one frame of sound attenuation parameter with a difference greater than the second sub-threshold can be identified as an abnormal sound attenuation parameter. Among them, the abnormal sound attenuation parameter with a difference greater than the preset second abnormal threshold belongs to the abnormal sound attenuation parameter with a larger deviation relative to the first statistical analysis parameter, and the abnormal sound attenuation parameter with a difference less than or equal to the second abnormal threshold belongs to the abnormal sound attenuation parameter with a smaller deviation relative to the first statistical analysis parameter.

[0121] Third, if the first statistical analysis parameter is the median of the sound attenuation parameters of multiple frames, and the comparison result is the ratio of the sound attenuation parameter to the median, then at least one frame of sound attenuation parameter with a ratio greater than the third sub-threshold can be identified as an abnormal sound attenuation parameter. Among them, the abnormal sound attenuation parameter with a ratio greater than the preset third abnormal threshold belongs to the abnormal sound attenuation parameter with a larger deviation relative to the first statistical analysis parameter, and the abnormal sound attenuation parameter with a ratio less than or equal to the third abnormal threshold belongs to the abnormal sound attenuation parameter with a smaller deviation relative to the first statistical analysis parameter.

[0122] Fourth, if the first statistical analysis parameter is the average of multiple frame sound attenuation parameters, and the comparison result is the ratio of the sound attenuation parameter to the average, then at least one frame of sound attenuation parameter with a ratio greater than the fourth sub-threshold can be identified as an abnormal sound attenuation parameter. Among them, abnormal sound attenuation parameters with a ratio greater than the preset fourth abnormal threshold are abnormal sound attenuation parameters with a larger deviation from the first statistical analysis parameter, and abnormal sound attenuation parameters with a ratio less than or equal to the fourth abnormal threshold are abnormal sound attenuation parameters with a smaller deviation from the first statistical analysis parameter.

[0123] In step S106, the ultrasound device can, in response to the deletion command, delete several frames of abnormal acoustic attenuation parameters specified by the deletion command from the multi-frame acoustic attenuation parameters that are displayed.

[0124] After deleting the corresponding abnormal acoustic attenuation parameters according to the deletion command, the ultrasound equipment may not display these deleted abnormal acoustic attenuation parameters. In other words, the ultrasound equipment may only display the acoustic attenuation parameters remaining after deletion in the multi-frame acoustic attenuation parameters.

[0125] by Figure 4 For example, ultrasound equipment can display, as shown in the image. Figure 4 The ultrasound equipment displays the multi-frame acoustic attenuation parameters shown in (1), and provides an abnormal alert for the two frames A1 and A2 with abnormal acoustic attenuation parameters. Subsequently, the ultrasound equipment responds by deleting the abnormal parameters. Figure 4 The deletion command for the abnormal sound attenuation parameters in frames A1 and A2 shown in (1) deletes the abnormal sound attenuation parameters in frames A1 and A2, as follows: Figure 4 As shown in (2). Only the remaining sound attenuation parameters after deletion are displayed, and the abnormal sound attenuation parameters of frames A1 and A2 are no longer displayed.

[0126] After deleting the corresponding abnormal acoustic attenuation parameter according to the deletion command, the ultrasound equipment can also weaken the display of the deleted abnormal acoustic attenuation parameter in the multi-frame acoustic attenuation parameter.

[0127] There are several ways to weaken the display of abnormal sound attenuation parameters that have been deleted.

[0128] One way to weaken the display is to show the deleted abnormal sound attenuation parameters in a different color than the sound attenuation parameters that have not been deleted. For example, the deleted abnormal sound attenuation parameters can be displayed in gray.

[0129] by Figure 4 (3) is an example. After deleting the abnormal sound attenuation parameters of frames A1 and A2, the bar charts corresponding to the abnormal sound attenuation parameters of frames A1 and A2 can be displayed in gray.

[0130] One way to weaken the display is to display the sound attenuation parameters that have not been deleted in a completely opaque manner (i.e., with 0% transparency), and display the abnormal sound attenuation parameters that have been deleted in a partially transparent manner (i.e., with greater than 0% transparency, such as 80% transparency).

[0131] by Figure 4 For example, in (4), after deleting the abnormal sound attenuation parameters of frames A1 and A2, the bar charts corresponding to the abnormal sound attenuation parameters of frames A1 and A2 can be displayed with 80% transparency, while the bar charts corresponding to the other sound attenuation parameters that were not deleted can be displayed with 0% transparency.

[0132] One way to weaken the display is to display the sound attenuation parameters that have not been deleted with a higher brightness, and the abnormal sound attenuation parameters that have been deleted with a lower brightness.

[0133] Before responding to a deletion instruction for at least one frame of abnormal acoustic attenuation parameters, the ultrasound device may obtain a deletion instruction as follows:

[0134] Receive a selection instruction for attenuation parameters of at least one frame of abnormal sound;

[0135] Receive a deletion instruction for at least one selected frame of abnormal sound attenuation parameters, wherein the deletion instruction includes a one-click deletion instruction and / or a single-frame deletion instruction, the one-click deletion instruction being used to delete at least one frame of abnormal sound attenuation parameters, and the single-frame deletion instruction being used to delete one frame of abnormal sound attenuation parameters.

[0136] If the ultrasound device receives a one-click delete command, it can identify all abnormal acoustic attenuation parameters selected in the previously received selection command as the abnormal acoustic attenuation parameters to be deleted as specified in the delete command, and delete all the abnormal acoustic attenuation parameters selected in the selection command.

[0137] For example, if the ultrasound device receives a selection command that selects the currently displayed 4 frames of abnormal sound attenuation parameters, the ultrasound device can delete all 4 frames of abnormal sound attenuation parameters after receiving a one-click delete command.

[0138] Please see Figure 5 (1) After receiving the selection command for selecting abnormal acoustic attenuation parameters A1 and A2, if the ultrasonic device receives a one-click deletion command, the ultrasonic device will directly delete A1 and A2, and display the bar chart of the two deleted acoustic attenuation parameters in gray on the display interface.

[0139] If the ultrasound device receives a single-frame deletion command, the ultrasound device can determine the abnormal sound attenuation parameter specified by the single-frame deletion command from at least one frame of sound attenuation parameters selected by the command, and delete the specified abnormal sound attenuation parameter.

[0140] The ultrasound device can continuously receive multiple single-frame deletion commands. For example, in response to the received selection command that selects 5 frames of abnormal sound attenuation parameters, the ultrasound device can receive a single-frame deletion command to delete one frame of abnormal sound attenuation parameters from these 5 frames, and then receive another single-frame deletion command to delete another frame of abnormal sound attenuation parameters from these 5 frames, and so on.

[0141] Please see Figure 5 (2) After receiving the selection instructions for selecting abnormal sound attenuation parameters A1 and A2, if the ultrasound device receives a single frame deletion instruction for A1, the ultrasound device will directly delete A1 and display the bar icon corresponding to A1 in gray in the display interface, while the bar icon corresponding to A2 will still be displayed in the manner of abnormal prompts.

[0142] The ultrasound device can receive selection instructions for at least one frame of abnormal sound attenuation parameters in a variety of ways, for example, it can receive selection instructions for at least one frame of abnormal sound attenuation parameters input by at least one of buttons, knobs and trackballs.

[0143] Alternatively, it can receive selection instructions for attenuation parameters of at least one frame of abnormal sound by selecting icons or options on a touchscreen.

[0144] The ultrasound device can receive a deletion command for at least one selected frame of anomalous acoustic attenuation parameters in a variety of ways, for example, it can receive a deletion command for at least one frame of anomalous acoustic attenuation parameters input by at least one of the following methods: buttons, knobs and trackballs.

[0145] Alternatively, it can receive a deletion command for at least one frame of abnormal sound attenuation parameters input via a delete icon or option on a touchscreen.

[0146] In some alternative embodiments, the ultrasound device may also receive a recovery instruction for at least one frame of deleted abnormal acoustic attenuation parameters to restore the display of at least one frame of deleted abnormal acoustic attenuation parameters.

[0147] The recovery display here can be:

[0148] If the ultrasound device does not display the deleted abnormal acoustic attenuation parameter, then after receiving the recovery command, the ultrasound device can continue to display the recovered abnormal acoustic attenuation parameter in the same way as before it was deleted.

[0149] If the ultrasound device weakens the display of deleted abnormal acoustic attenuation parameters, then after receiving a recovery command, the ultrasound device can cancel the weakened display status of the restored abnormal acoustic attenuation parameters.

[0150] The above recovery command can be a one-click recovery command. If it is a one-click recovery command, the ultrasound device can restore and display all abnormal acoustic attenuation parameters that were deleted after the start of this scan.

[0151] The above recovery command can be a partial recovery command. If it is a partial recovery command, the ultrasound device can restore and display at least one frame of the deleted abnormal sound attenuation parameters specified by the partial recovery command.

[0152] The ultrasound device can receive recovery commands in a variety of ways, such as receiving recovery commands for at least one frame of deleted abnormal acoustic attenuation parameters input via at least one of buttons, knobs, and trackballs.

[0153] Alternatively, it can receive a command to restore at least one frame of abnormal sound attenuation parameters that has been deleted, input via a delete icon or option on the touchscreen.

[0154] This application also provides a method for displaying ultrasound parameters; please refer to [link to relevant documentation]. Figure 6 Here is a flowchart of the method, which may include the following steps.

[0155] S601, Displays an interface for selecting at least two ultrasound scanning modes, the at least two ultrasound scanning modes being used to acquire at least two ultrasound parameters of a target area of ​​a target tissue, the at least two ultrasound scanning modes including a first ultrasound scanning mode and a second ultrasound scanning mode.

[0156] S602, based on the first ultrasound mode, scan the target tissue to obtain multiple frames of first ultrasound parameters of the first target region of the target tissue, and based on the second ultrasound mode, scan the target tissue to obtain multiple frames of second ultrasound parameters of the second target region of the target tissue.

[0157] S603 displays multiple frames of first ultrasound parameters and multiple frames of second ultrasound parameters.

[0158] S604, determine at least one first abnormal ultrasound parameter in a plurality of first ultrasound parameters, and / or determine at least one second abnormal ultrasound parameter in a plurality of second ultrasound parameters.

[0159] S605, provide an abnormality alert for at least one frame of first abnormal ultrasound parameters and / or at least one frame of second abnormal ultrasound parameters.

[0160] S606, delete at least one frame of first abnormal ultrasound parameters, and / or delete at least one frame of second abnormal ultrasound parameters.

[0161] The beneficial effects of this embodiment are as follows: After displaying multiple frames of first ultrasound parameters and multiple frames of second ultrasound parameters, the ultrasound device can simultaneously identify the first abnormal ultrasound parameter and the second abnormal ultrasound parameter and provide abnormal prompts respectively. This allows the user to intuitively see the first abnormal ultrasound parameter and / or the second abnormal ultrasound parameter through the abnormal prompts, and thus conveniently trigger a deletion command to delete at least one frame of the first abnormal ultrasound parameter and / or the second abnormal ultrasound parameter. Therefore, this solution can help the user intuitively find and remove abnormal ultrasound parameters, improving the convenience of the user's ultrasound scan.

[0162] Optionally, after deleting at least one frame of the first abnormal ultrasound parameters, the ultrasound device may display at least one frame of the first ultrasound parameters in the following manner:

[0163] Only display the remaining first ultrasound parameters after deletion in the multi-frame first ultrasound parameters, or weaken the display of the first abnormal ultrasound parameters deleted in the multi-frame first ultrasound parameters.

[0164] Optionally, after deleting at least one frame of the second abnormal ultrasound parameters, the ultrasound device may display at least one frame of the second ultrasound parameters in the following manner:

[0165] Only display the remaining second ultrasound parameters after deletion in multiple frames of second ultrasound parameters, or weaken the display of the deleted second abnormal ultrasound parameters in multiple frames of second ultrasound parameters.

[0166] The above display method can be found in the relevant figures and contents of the foregoing embodiments where the deleted abnormal sound attenuation parameters are not displayed or are displayed in a weakened manner, and will not be repeated here.

[0167] Optionally, the first and second ultrasonic scanning modes include at least two of the following: shear wave elastic scanning mode, acoustic attenuation scanning mode, viscoelastic scanning mode, photoacoustic scanning mode, sound velocity scanning mode, transient elastic scanning mode, and strain elastic scanning mode. For example, the first ultrasonic scanning mode may be an elastic scanning mode, and the second ultrasonic scanning mode may be an acoustic attenuation scanning mode; or the first ultrasonic scanning mode may be a viscoelastic scanning mode, and the second ultrasonic scanning mode may be a sound velocity scanning mode.

[0168] In step S601, the interface displayed by the ultrasonic device may include a variety of ultrasonic scanning modes, including but not limited to shear wave elastic scanning mode, acoustic attenuation scanning mode, viscoelastic scanning mode, photoacoustic scanning mode, sound velocity scanning mode, instantaneous elastic scanning mode, and strain elastic scanning mode. The user can select at least two ultrasonic scanning modes, for example, the user can select elastic scanning mode and acoustic attenuation scanning mode, or the user can select elastic scanning mode, acoustic attenuation scanning mode, and viscoelastic scanning mode.

[0169] Each ultrasound scanning mode is used to obtain the ultrasound parameters corresponding to that mode in the target area of ​​the target tissue.

[0170] For example, in elastic scanning mode, the ultrasound device is used to obtain elasticity measurements at various locations within the target area of ​​the target tissue based on a frame of ultrasound echo data, and then obtain statistical indices of multiple elasticity values ​​as a frame of elasticity parameters of the target area.

[0171] In acoustic attenuation scanning mode, the ultrasound equipment is used to obtain acoustic attenuation measurements at various locations within the target area of ​​the target tissue based on a frame of ultrasound echo data, and then obtain statistical indicators of multiple acoustic attenuation values ​​as a frame of acoustic attenuation parameters of the target area.

[0172] In viscoelastic scanning mode, the ultrasound equipment is used to obtain viscoelastic measurements at various locations within the target area of ​​the target tissue based on a frame of ultrasound echo data, and then obtain statistical indices of multiple viscoelastic values ​​as a frame of viscoelastic parameters of the target area.

[0173] The types of statistical indicators can be found in the aforementioned examples and will not be repeated here.

[0174] In step S602, the ultrasound device can continuously scan the target tissue. During the scanning process, for each frame of ultrasound echo data obtained, the ultrasound device can process the frame of ultrasound echo data based on each ultrasound scanning mode selected in S601 to obtain the ultrasound parameters corresponding to each ultrasound scanning mode.

[0175] In other words, when multiple ultrasound scanning modes are selected, for each frame of ultrasound echo data obtained during the scan, the ultrasound equipment can obtain multiple ultrasound parameters corresponding to the selected ultrasound scanning modes based on that frame of ultrasound echo data.

[0176] For example, if the elasticity scan mode and the acoustic attenuation scan mode are selected, each scan in S602 will obtain a frame of ultrasonic echo data, and a frame of elasticity parameters and a frame of acoustic attenuation parameters can be obtained based on the frame of data.

[0177] If the elastic scanning mode, acoustic attenuation scanning mode, or viscoelastic scanning mode is selected, each scan in S602 will obtain one frame of ultrasonic echo data, and one frame of elastic parameters, one frame of acoustic attenuation parameters, and one frame of viscoelastic parameters can be obtained based on this frame of data.

[0178] The method of obtaining a frame of ultrasonic parameters based on obtaining a frame of ultrasonic echo data can be found in the above embodiment, which describes the method of obtaining a frame of acoustic attenuation parameters based on a frame of ultrasonic echo data, and will not be repeated here.

[0179] In step S603, the method of displaying multiple frames of first ultrasound parameters and the method of displaying multiple frames of second ultrasound parameters can both refer to the method of displaying multiple frames of acoustic attenuation parameters in the foregoing embodiments, and will not be repeated here.

[0180] It should be noted that, in order to enable users to intuitively see whether different types of multi-frame ultrasound parameters are obtained at the same time, the ultrasound equipment can display different types of multi-frame ultrasound parameters obtained under various ultrasound scanning modes on the same interface. When displaying, the multi-frame ultrasound parameters of different types obtained at the same time are aligned in the Y-axis direction. In other words, the multi-frame ultrasound parameters of different types obtained at the same time based on the same frame of ultrasound echo data are arranged at the same horizontal coordinate position.

[0181] As an example, see Figure 7 After selecting the shear wave elastic scanning mode, acoustic attenuation scanning mode, or viscoelastic scanning mode in S601, the ultrasonic equipment can scan and obtain multiple frames of elastic parameters, multiple frames of viscoelastic parameters, and multiple frames of acoustic attenuation parameters. Specifically, the shear wave elastic parameters can be the average of multiple elastic measurements within the target area (i.e.,...). Figure 7 The viscoelastic parameter (EMean) shown can be the average of multiple viscoelastic measurements within the target area (i.e., Figure 7The Vi Mean shown can be the average of multiple sound attenuation measurements within the target area (i.e., Vi Mean). Figure 7 The USAT Mean is shown.

[0182] Once the ultrasound equipment begins scanning, it can determine one frame of elastic parameter M1, one frame of viscoelastic parameter N1, and one frame of acoustic attenuation parameter A1 based on the obtained frame of ultrasound echo data. It can be seen that M1, N1, and A1 are aligned in the Y-axis direction on the display interface. Thus, the user can intuitively see that M1, N1, and A1 represent one frame of elastic parameter, one frame of viscoelastic parameter, and one frame of acoustic attenuation parameter obtained by the ultrasound equipment at the same time based on the same frame of ultrasound echo data.

[0183] Similarly, various ultrasound parameters obtained subsequently based on the same frame of ultrasound echo data are all displayed aligned in the Y-axis direction.

[0184] After obtaining different types of multi-frame ultrasound parameters, the ultrasound equipment can determine the corresponding statistical analysis parameters for each type of multi-frame ultrasound parameter, and display and provide anomaly prompts for the determined statistical analysis parameters.

[0185] Optionally, the ultrasound equipment can determine the statistical analysis parameters corresponding to the first ultrasound parameters of multiple frames in the following manner:

[0186] The statistical analysis parameters corresponding to the first ultrasound parameters of multiple frames are determined. The statistical analysis parameters corresponding to the first ultrasound parameters of multiple frames include at least one of the third statistical analysis parameter and the fourth statistical analysis parameter. The third statistical analysis parameter includes at least one of the median, interquartile range, mean and standard deviation. The fourth statistical analysis parameter includes the ratio or difference of at least two of the median, interquartile range, mean and standard deviation.

[0187] If at least one of the third and fourth statistical analysis parameters is abnormal, an abnormality warning will be given for at least one of the third and fourth statistical analysis parameters that is abnormal.

[0188] And / or, the ultrasound equipment can determine the statistical analysis parameters corresponding to multiple frames of second ultrasound parameters in the following manner:

[0189] The statistical analysis parameters corresponding to the second ultrasound parameters of multiple frames are determined. The statistical analysis parameters corresponding to the second ultrasound parameters of multiple frames include at least one of the fifth statistical analysis parameter and the sixth statistical analysis parameter. The fifth statistical analysis parameter includes at least one of the median, interquartile range, mean and standard deviation. The sixth statistical analysis parameter includes the ratio or difference of at least two of the median, interquartile range, mean and standard deviation.

[0190] If at least one of the fifth and sixth statistical analysis parameters is abnormal, an abnormality warning will be issued for at least one of the fifth and sixth statistical analysis parameters that is abnormal.

[0191] The determination method and anomaly alert method for the statistical analysis parameters corresponding to the first and second ultrasound parameters mentioned above can refer to the method for determining the statistical analysis parameters of the acoustic attenuation parameter and providing anomaly alerts in the foregoing embodiments, and will not be repeated here.

[0192] The statistical analysis parameters corresponding to each type of multi-frame ultrasound parameter can also be updated after the corresponding abnormal multi-frame ultrasound parameter is deleted. The updating method can refer to the method of updating the statistical analysis parameters of the acoustic attenuation parameter in the previous embodiment, which will not be repeated here.

[0193] In step S604, the ultrasound device can determine at least one frame of first abnormal ultrasound parameters in multiple frames of first ultrasound parameters, and at least one frame of second abnormal ultrasound parameters in multiple frames of second ultrasound parameters. It can also simultaneously determine at least one frame of first abnormal ultrasound parameters in multiple frames of first ultrasound parameters and at least one frame of second abnormal ultrasound parameters in multiple frames of second ultrasound parameters.

[0194] For each type of ultrasound parameter, the ultrasound device can independently determine at least one abnormal ultrasound parameter from multiple frames of that type of ultrasound parameter based on the statistical analysis parameters corresponding to that type of ultrasound parameter. The specific triggering conditions and determination methods can be found in the content on determining abnormal sound attenuation parameters in the aforementioned embodiments, and will not be repeated here.

[0195] Optionally, the ultrasound equipment may also determine at least one frame of first abnormal ultrasound parameters and at least one frame of second abnormal ultrasound parameters in a linked manner in any of the following ways:

[0196] First, if at least one fourth statistical analysis parameter is abnormal, multiple frames of first ultrasound parameters and at least one third statistical analysis parameter are compared. Based on the comparison results, at least one frame of first abnormal ultrasound parameter is determined, and at least one frame of second ultrasound parameter corresponding to the at least one frame of first abnormal ultrasound parameter is determined as the second abnormal ultrasound parameter. The method of determining at least one frame of first abnormal ultrasound parameter based on the comparison results can refer to the content of determining at least one frame of abnormal sound attenuation parameter based on the comparison results in the aforementioned embodiment.

[0197] Second, if at least one sixth statistical analysis parameter is abnormal, multiple frames of second ultrasound parameters are compared with at least one fifth statistical analysis parameter. Based on the comparison results, at least one frame of second abnormal ultrasound parameter is determined, and at least one frame of first ultrasound parameter corresponding to the at least one frame of second abnormal ultrasound parameter is determined as the first abnormal ultrasound parameter. The method of determining at least one frame of second abnormal ultrasound parameter based on the comparison results can refer to the content of determining at least one frame of abnormal sound attenuation parameter based on the comparison results in the aforementioned embodiment.

[0198] In other words, if the ultrasound device determines at least one frame of first abnormal ultrasound parameters based on the statistical analysis parameters corresponding to multiple frames of first ultrasound parameters, then the ultrasound device can also determine the second ultrasound parameter corresponding to the first abnormal ultrasound parameter as the second abnormal ultrasound parameter; if the ultrasound device determines at least one frame of second abnormal ultrasound parameters based on the statistical analysis parameters corresponding to multiple frames of second ultrasound parameters, then the ultrasound device can also determine the first ultrasound parameter corresponding to the second abnormal ultrasound parameter as the first abnormal ultrasound parameter.

[0199] The correspondence between a first frame of ultrasound parameters and a second frame of ultrasound parameters means that the first frame of ultrasound parameters and the second frame of ultrasound parameters are two types of data obtained by the ultrasound equipment at the same time based on the same frame of ultrasound echo data.

[0200] As an example, suppose the ultrasound device is in Figure 8 The interface shown displays multiple frames of elastic parameters, multiple frames of viscoelastic parameters, and multiple frames of acoustic attenuation parameters. Then, based on the statistical analysis parameters of the multiple frames of acoustic attenuation parameters, the ultrasound equipment determines that the acoustic attenuation parameters of frames A3 to A5 are abnormal acoustic attenuation parameters. At this time, the ultrasound equipment can also determine the elastic parameters of frames M3 to M5, which are obtained simultaneously with A3 to A5, as abnormal elastic parameters, and the viscoelastic parameters of frames N3 to N5, which are obtained simultaneously with A3 to A5, as abnormal viscoelastic parameters.

[0201] In S605, if the ultrasound device determines at least one frame of first abnormal ultrasound parameters, the ultrasound device can provide an abnormality alert for at least one frame of first abnormal ultrasound parameters in the following manner:

[0202] Anomalies are indicated by at least one of the following methods: color, icon, shape, and sound.

[0203] If the ultrasound equipment identifies at least one frame of second abnormal ultrasound parameters, the ultrasound equipment can indicate the abnormality of at least one frame of second abnormal ultrasound parameters in the following manner:

[0204] Anomalies are indicated by at least one of the following methods: color, icon, shape, and sound, for at least one frame of second abnormal ultrasound parameters.

[0205] All of the above error message methods can be found in the previous embodiments for error message prompts regarding abnormal sound attenuation parameters, and will not be repeated here.

[0206] Similar to the aforementioned acoustic attenuation parameters, for each ultrasonic parameter, the ultrasonic device can also differentiate and display the abnormal ultrasonic parameter based on the degree of deviation. The method of differentiation and display can be found in the aforementioned embodiments regarding... Figure 3 The content will not be repeated here.

[0207] In step S606, the ultrasound device may sequentially delete at least one frame of first abnormal ultrasound parameters and at least one frame of second abnormal ultrasound parameters.

[0208] Specifically, the ultrasound device can delete at least one frame of the first abnormal ultrasound parameter in response to a first deletion command for the first abnormal ultrasound parameter, and then delete at least one frame of the second abnormal ultrasound parameter in response to a second deletion command for the second abnormal ultrasound parameter.

[0209] Alternatively, the ultrasound device may delete at least one frame of the second abnormal ultrasound parameter in response to a second deletion instruction for the second abnormal ultrasound parameter, and then delete at least one frame of the first abnormal ultrasound parameter in response to a first deletion instruction for the first abnormal ultrasound parameter.

[0210] The methods for deleting the first abnormal ultrasound parameter in response to the first deletion command and deleting the second abnormal ultrasound parameter in response to the second deletion command can be found in the previous embodiments regarding the deletion of abnormal acoustic attenuation parameters in response to deletion commands, and will not be repeated here.

[0211] In step S606, the ultrasound device may also delete at least one frame of first abnormal ultrasound parameters and at least one frame of second abnormal ultrasound parameters in conjunction with the ultrasound device.

[0212] Specifically, the ultrasound device can receive a linkage deletion command, and then delete at least one frame of first abnormal ultrasound parameters and at least one frame of second abnormal ultrasound parameters in response to the linkage deletion command.

[0213] The ultrasound device can receive a linkage deletion command for deleting at least one specified first abnormal ultrasound parameter frame. In response to the linkage deletion command, the device can delete the specified at least one first abnormal ultrasound parameter frame. At the same time, it can also delete at least one second abnormal ultrasound parameter frame acquired at the same time as the specified at least one first abnormal ultrasound parameter frame.

[0214] As an example, see Figure 9The ultrasound equipment can receive a linked deletion command for deleting abnormal acoustic attenuation parameters A3 to A5. In response to this linked deletion command, the ultrasound equipment deletes the abnormal acoustic attenuation parameters in frames A3 to A5, and also deletes the abnormal viscoelastic parameters in frames N3 to N5 acquired simultaneously with the abnormal acoustic attenuation parameters in frames A3 to A5, as well as the abnormal elastic parameters in frames M3 to M5 acquired simultaneously with the abnormal acoustic attenuation parameters in frames A3 to A5. Figure 9 As can be seen, the bar charts corresponding to these deleted ultrasound parameters are all displayed in gray, indicating that the ultrasound parameters of the corresponding frames have been deleted.

[0215] Ultrasonic equipment can receive linkage deletion commands in multiple ways:

[0216] Receive a linkage deletion command for at least one frame of first abnormal ultrasound parameters and at least one frame of second abnormal ultrasound parameters input by at least one of the following methods: button, knob and trackball; or receive a linkage deletion command for at least one frame of first abnormal ultrasound parameters and at least one frame of second abnormal ultrasound parameters input by a linkage deletion icon or option on a touch screen.

[0217] Optionally, users can perform deletion operations using various methods such as buttons, knobs, and trackballs. If the control used to control the linkage deletion or single parameter deletion is in the linkage deletion state when performing the deletion operation, the ultrasound device can obtain a linkage deletion command based on this deletion operation, and then delete at least one frame of the first abnormal ultrasound parameter and at least one frame of the second abnormal ultrasound parameter in the linkage manner as described above. If the control is in the single parameter deletion state when performing the deletion operation, the ultrasound device can obtain a deletion command, a first deletion command, or a second deletion command for deleting the acoustic attenuation parameter based on this deletion operation, and delete at least one frame of abnormal acoustic attenuation parameter, or delete at least one frame of the first abnormal ultrasound parameter, or delete at least one frame of the second abnormal ultrasound parameter according to the obtained command.

[0218] Optionally, the functions of the controls described above for controlling linkage deletion or single parameter deletion can also be implemented through physical buttons on the ultrasonic device.

[0219] Optionally, when in the single parameter deletion state, the ultrasound device can switch between multiple ultrasound parameters based on the user's operation of the controls or physical buttons to switch to the abnormal ultrasound parameter that needs to be deleted, and can select the abnormal ultrasound parameter to be deleted from at least one frame of abnormal ultrasound parameters based on the user's operation of the controls or physical buttons.

[0220] The ultrasound device can receive a recovery command to restore the display of at least one deleted frame of first abnormal ultrasound parameters, or to restore the display of at least one deleted frame of second abnormal ultrasound parameters. For specific recovery methods, please refer to the foregoing embodiments for restoring the display of deleted abnormal acoustic attenuation parameters.

[0221] The ultrasound device can also receive a linkage recovery command. When a linkage recovery command is received, the ultrasound device can restore the display of at least one frame of the first abnormal ultrasound parameter that was deleted, as specified by the command, and can also restore the display of at least one frame of the second abnormal ultrasound parameter that was acquired at the same time as the restored first abnormal ultrasound parameter. Alternatively, it can restore the display of at least one frame of the second abnormal ultrasound parameter that was deleted, as specified by the command, and can also restore the display of at least one frame of the first abnormal ultrasound parameter that was acquired at the same time as the restored second abnormal ultrasound parameter.

[0222] Optionally, the ultrasound equipment can also display the ultrasound images corresponding to each selected ultrasound scanning mode in real time. For example, if the shear wave elastic scanning mode is selected, the elastic image can be displayed in real time; if the viscoelastic scanning mode is selected, the viscoelastic image can be displayed in real time; if the photoacoustic scanning mode is selected, the photoacoustic image can be displayed in real time; if the sound velocity scanning mode is selected, the sound velocity image can be displayed in real time; if the transient elastic scanning mode is selected, the transient elastic image can be displayed in real time; and if the strain elastic scanning mode is selected, the strain elastic image can be displayed in real time.

[0223] The methods for acquiring images corresponding to the various ultrasonic scanning modes described above can be found in the methods for acquiring acoustic attenuation images in the aforementioned embodiments, and will not be repeated here.

[0224] The first and second ultrasound parameters in the above embodiments are only examples. In actual application scenarios, ultrasound equipment can select three or more ultrasound modes based on the user's operation. Correspondingly, three or more multi-frame ultrasound parameters can be obtained and displayed through ultrasound scanning. In this case, ultrasound equipment can also perform linked deletion, restoration, and abnormal prompting of other ultrasound parameters based on the instruction of any one ultrasound parameter, and is not limited to the two ultrasound parameters in the above examples.

[0225] This application also provides an ultrasonic device; please refer to [link to relevant documentation]. Figure 10 The diagram below shows the structure of the ultrasound device, which may include an ultrasound probe 1001, a processor 1002, and a display 1003.

[0226] Among them, the ultrasound probe 1001 is used to emit ultrasound waves to the target tissue and receive the corresponding ultrasound echoes to obtain ultrasound echo data of the target tissue.

[0227] Processor 1002 is used to execute the display method provided in any embodiment of this application;

[0228] Display 1003 is used to display the results processed by the processor.
