[0002] Ultrasonic diagnosis is a diagnostic method that applies ultrasound technology to the human body to measure and understand physiological or tissue structure data and morphology, thereby detecting diseases and providing diagnostic suggestions. Ultrasonic diagnosis has advantages such as being non-invasive, painless, convenient, and intuitive, and is therefore widely used in the diagnosis and treatment of various diseases. Currently, ultrasound diagnostic technology has developed various working modes to meet the diagnostic and treatment needs of different diseases, each producing ultrasound images in a specific format. However, for the same ultrasound examination system, further improvements are still needed to determine how to adjust the type of displayed ultrasound images according to the diagnostic and treatment needs of different diseases. Summary of the Invention

[0050] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. Terms describing position and direction in the present invention are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of the present invention. The accompanying drawings of the present invention are for illustrative purposes only and do not represent actual proportions.

[0051] It should be noted that specific details are set forth in the following description to provide a full understanding of the invention. However, the invention can be practiced in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below. The following description is a preferred embodiment for carrying out the present application; however, the description is for the purpose of illustrating the general principles of the application and is not intended to limit the scope of the application. The scope of protection of this application shall be determined by the appended claims.

[0052] The following description, in conjunction with the accompanying drawings, details an image display method for a medical ultrasound examination instrument and the medical ultrasound examination instrument provided by embodiments of the present invention.

[0053] This invention provides an image display method for a medical ultrasound examination instrument, such as... Figure 1 As shown, it includes:

[0054] S110. Obtain ultrasound images and image display parameters and primitives corresponding to each ultrasound image.

[0055] Optionally, the primitives corresponding to the ultrasound image include at least one of the following:

[0056] Grayscale bars, color scale bars, time gain compensation (TGC), lateral gain compensation (LGC), region of interest (ROI), measurement markers, annotations, sampling markers for viewing spectral information, a scale for representing image imaging depth, ultrasound probe position markers, and zoom boxes.

[0057] In the specific implementation process, when acquiring corresponding graphic elements based on ultrasound images, the graphic elements corresponding to that type of ultrasound image can be determined and acquired by identifying the type of ultrasound image. For example, if the acquired ultrasound image is a C-mode ultrasound image, then the first type of graphic elements corresponding to the C-mode ultrasound image includes color scale bars, ROIs, etc. Furthermore, in the process of acquiring corresponding graphic elements based on ultrasound images, the second type of graphic elements corresponding to each individual ultrasound image can also be determined and acquired by establishing a correspondence between ultrasound images and second type graphic elements by the user. This correspondence can be a mapping table, or ultrasound images with a correspondence can be assigned the same label to the second type of graphic elements. For example, since medical ultrasound examination equipment continuously acquires ultrasound images frame by frame, a frame number is assigned to each ultrasound image after acquisition for marking. In this way, when a user adds measurement marks, annotations, or other second-type graphic elements to the currently displayed ultrasound image during medical diagnosis, the frame number will be set to the same as that of the ultrasound image. When the ultrasound image is acquired again to display a medical image containing the ultrasound image, the second-type graphic elements with the same frame number will be searched for and acquired. Other second-type graphic elements with different frame numbers from the acquired ultrasound image will not be acquired and will not be displayed.

[0058] S130. Adjust the display effect of the corresponding ultrasound image according to the image display parameters.

[0059] Optionally, the image display parameters include at least one of the following:

[0060] Image display area, image imaging depth, image scaling factor, scan speed, baseline setting parameters, focus position, flip state, rotation state.

[0061] In this embodiment of the invention, the image imaging depth refers to the depth to which the ultrasound waves emitted by the ultrasound probe reach the human tissue, which is equivalent to the distance between the cross-section of the human tissue corresponding to the ultrasound image and the ultrasound probe. The scanning speed refers to the number of lines displayed per second in the line mode ultrasound image, indicating the speed at which the line mode ultrasound image is displayed.

[0062] S140. Determine and load the display layout, and display the corresponding adjusted ultrasound images at each preset display position in the first layer of the display layout, and display the graphic elements corresponding to the ultrasound images in the first layer in the second layer of the display layout.

[0063] In any display layout, at least one of the following properties differs from the other display layouts:

[0064] (1) The number of ultrasound images displayed simultaneously.

[0065] For example, the display layout for displaying one ultrasound image at the same time is different from the display layout for displaying two ultrasound images at the same time.

[0066] (2) The update status of each ultrasound image displayed simultaneously.

[0067] Optionally, the update status includes real-time status and frozen status.

[0068] Since medical ultrasound examination equipment continuously acquires ultrasound images frame by frame, the real-time state is the state of updating frame by frame, and the frozen state is the state of temporarily maintaining a certain frame of ultrasound image without updating.

[0069] For example, in a display layout that simultaneously displays two ultrasound images, the layout that displays two real-time ultrasound images is different from the layout that displays one real-time image and one frozen image.

[0070] (3) The types of ultrasound images displayed simultaneously.

[0071] like Figure 2 As shown, ultrasound image types can evolve from B-mode (Brightnessmode) and C-mode (Color Flow Mapping) ultrasound images (belonging to frame-mode ultrasound images) and D-mode (Doppler mode) and M-mode (Motion mode) ultrasound images (belonging to line-mode ultrasound images). Specifically, ultrasound image types include at least one of the following:

[0072] Ultrasound images in various modes, including Pulse Wave (PW) pre-activated mode, Continuous Wave (CW) pre-activated mode, wide-view imaging mode, puncture mode, elastography mode, transillumination mode, Doppler Power Imaging (DPI) mode, Directional Power Doppler Imaging (DPDI) mode, Tissue Doppler Imaging (TDI) mode, Spectrum Color Velocity (SCV) mode, 3-Dimension Pulse Wave (3DPW) mode, CW mode, Anatomical M Mode (AMM) mode, Anatomical M Mode, and Color Motion Mode (CM).

[0073] For example, in a display layout that simultaneously displays two ultrasound images, the display layout that simultaneously displays one B-mode ultrasound image and one C-mode ultrasound image is different from the display layout that simultaneously displays one B-mode ultrasound image and one PW-mode ultrasound image.

[0074] Thus, by setting different display layouts according to the needs of medical diagnosis, different display layouts display different numbers, types, and update statuses of ultrasound images, and displaying the corresponding graphic elements of the ultrasound images through two layers, the same device can display multiple forms of medical images, and the parameters of each ultrasound image and graphic element are separated and do not affect each other.

[0075] Optionally, if the ultrasound image includes a frozen ultrasound image, before adjusting the display effect of the corresponding ultrasound image according to the image display parameters, the method further includes:

[0076] S120. Edit the corresponding frozen ultrasound image according to the image editing parameters.

[0077] The image editing parameters include image gain and image dynamic range.

[0078] In practice, image editing parameters can be input by the user through knobs or buttons on the medical ultrasound examination equipment.

[0079] In this way, by editing the frozen ultrasound image according to the image gain and dynamic range input by the user, the brightness and contrast of the frozen ultrasound image are adjusted before it is displayed, so as to ensure the display effect of the frozen ultrasound image and facilitate the user's medical diagnosis.

[0080] As an optional implementation, step S140, determining and loading the display layout, displaying the corresponding adjusted ultrasound images at each preset display position in the first layer of the display layout, and displaying the graphic elements corresponding to the ultrasound images in the first layer in the second layer of the display layout, specifically includes:

[0081] Determine and load the first display layout (e.g.) Figure 3 As shown, an adjusted real-time B-mode ultrasound image and an adjusted real-time C-mode ultrasound image are overlaid in the first area of ​​the first layer of the first display layout. An adjusted real-time PW-mode ultrasound image is displayed in the second area of ​​the first layer of the first display layout. Grayscale bars, color scale bars, a scale for representing image imaging depth, and a region of interest (ROI) are displayed in the second layer of the first display layout. Figure 3 (not shown in the image) Ultrasonic probe position mark ( Figure 3 (Not shown in the image).

[0082] As another optional implementation, step S120, editing the corresponding frozen ultrasound image according to the image editing parameters, specifically includes:

[0083] Edit the corresponding frozen B-mode ultrasound image according to the image editing parameters;

[0084] Step S140, determining and loading the display layout, displaying the corresponding adjusted ultrasound images at each preset display position in the first layer of the display layout, and displaying the graphic elements corresponding to the ultrasound images in the first layer in the second layer of the display layout, specifically includes:

[0085] Determine and load the second display layout (e.g.) Figure 4 As shown), an adjusted real-time B-mode ultrasound image is displayed in the first and second areas of the first layer of the second display layout, respectively. An adjusted frozen B-mode ultrasound image is displayed in the third and fourth areas of the first layer of the second display layout, respectively. Grayscale bars, a scale for indicating image imaging depth, and ultrasound probe position markers are displayed in the second layer of the first display layout. Figure 4 (Not shown in the image).

[0086] The frozen B-mode ultrasound image in the third region is obtained by freezing the real-time B-mode ultrasound image in the first region, and the frozen B-mode ultrasound image in the fourth region is obtained by freezing the real-time B-mode ultrasound image in the second region.

[0087] For example, at a certain moment, the medical ultrasound examination instrument displays a real-time B-mode ultrasound image in the first area. If the user triggers a freeze command on the real-time B-mode ultrasound image in the first area, the current B-mode ultrasound image in the first area is saved and displayed in the third area until the user triggers the freeze command again. The frozen B-mode ultrasound image in the fourth area is similar to the frozen B-mode ultrasound image in the third area, and therefore will not be described further.

[0088] Optionally, if the graphic element includes the measurement mark, then the graphic element corresponding to the ultrasound image of the first layer is displayed in the second layer of the display layout, specifically including:

[0089] In the second layer of the display layout, the graphic of the measurement mark is drawn and displayed using the drawing feature points and shape of the measurement mark.

[0090] For example, if the measurement mark is a circular measurement mark used to indicate the area of ​​a specified range, then a graphic of the circular measurement mark can be drawn and displayed based on the center and radius of the circular measurement mark.

[0091] In this way, compared with directly rendering and displaying the graphic of the measurement mark, drawing the graphic of the measurement mark by drawing feature points and shapes and then rendering and drawing it can avoid changes in the ultrasound image area corresponding to the measurement mark after the corresponding ultrasound image is edited or the display effect is adjusted.

[0092] Because users often need to measure certain tissues and organs during medical examinations, and these tissues and organs may be captured in multiple ultrasound images from different positions and angles, current medical ultrasound examination equipment can only measure data from a single ultrasound image and cannot perform cross-image measurements. Therefore, in this embodiment of the invention, optionally, before rendering the measurement markers, the following steps are also included:

[0093] Determine the ultrasound image corresponding to the measurement marker;

[0094] For any ultrasound image corresponding to the measurement mark, the measurement result of the measurement content of the measurement mark in the ultrasound image is calculated according to the image parameters of the ultrasound image, wherein the image parameters include the image display parameters and the image measurement parameters;

[0095] The total measurement result is calculated based on the measurement results of all ultrasound images corresponding to the measurement mark, and the total measurement result is added to the measurement mark;

[0096] Rendering the measurement markers also includes:

[0097] Render the overall measurement results.

[0098] In practice, the image measurement parameters include the pixel coordinates of the probe origin and the pixels corresponding to the probe radius.

[0099] For example, if a certain organ is large, two ultrasound images, one of its left half and one of its right half, are acquired by a medical ultrasound examination device and displayed in a corresponding layout, resulting in an image like this. Figure 5 The image shown is a medical image composed of two ultrasound images and corresponding grayscale bars and rulers. If a user needs to measure the width of an organ across the images, a measurement line segment can be drawn on the two ultrasound images. Accordingly, firstly, the two ultrasound images corresponding to the measurement line segment are determined (for example, the frame number of the measurement line segment is set to the frame number of the two ultrasound images). Then, for each portion of the measurement line segment in the two ultrasound images, the actual length of the corresponding organ is calculated based on the image parameters of the corresponding ultrasound images (e.g., image display parameters such as image scaling factor and image measurement parameters such as pixels corresponding to the probe radius). Finally, the actual lengths of the two portions of the line segment are added together to obtain the final length of the measurement line segment.

[0100] In this way, by calculating the measurement results of the measurement marks in each ultrasound image according to the correspondence between the measurement marks and the ultrasound images, and finally calculating the total measurement result based on each measurement result, cross-image measurement of ultrasound images displayed simultaneously on the display layout is realized.

[0101] Optionally, after step S140, the method further includes:

[0102] S150. In response to the graphic element editing instruction, determine the ultrasound image corresponding to the graphic element editing instruction, and edit the graphic element corresponding to the ultrasound image according to the graphic element editing instruction.

[0103] If an ultrasound image and a second type of graphic element are associated through frame numbers, then when editing the second type of graphic element corresponding to the ultrasound image, the second type of graphic element is set with the same frame number as the ultrasound image. For example, if the graphic element editing command is an annotation command, then when adding a user-inputted annotation, the annotation is set with the same frame number as the currently displayed ultrasound image so that the annotation is displayed on the second layer when the ultrasound image is displayed again. For graphic elements such as grayscale bars, color scale bars, TGC, LGC, and rulers, their graphic element editing commands are also used to adjust the image parameters when acquiring the corresponding ultrasound image. For example, the graphic element editing command for grayscale bars / color scale bars is also used to adjust the grayscale / color scale of the acquired ultrasound image; the graphic element editing command for TGC / LGC is also used to adjust the TGC / LGC of the acquired ultrasound image; and the graphic element editing command for rulers is also used to adjust the image imaging depth of the acquired ultrasound image.

[0104] After rendering and displaying the medical images, the images displayed in the current layout can be saved for later display.

[0105] As an optional implementation, the method further includes:

[0106] S161. Save the ultrasound image in the medical image format of the first layer, and save the corresponding graphic elements in the medical image format of the second layer.

[0107] This ensures that the ultrasound image and the primitive are separated and do not interfere with each other.

[0108] As another optional implementation, the method further includes:

[0109] S162. The ultrasound image and the corresponding graphic elements are merged into a medical image on the same layer and then saved.

[0110] This reduces the amount of data that needs to be saved.

[0111] Furthermore, the method also includes: S163, saving the image display parameters, image editing parameters, and image measurement parameters of the ultrasound image.

[0112] Optionally, when saving measurement marks, the measurement marks are saved in a way that saves the drawn feature points and shapes.

[0113] This ensures that the measurement area of ​​the measurement marker will not change due to changes in the image display parameters of the corresponding ultrasound image.

[0114] Based on the same inventive concept, embodiments of the present invention also provide a medical ultrasound examination instrument, such as... Figure 6 As shown, it includes:

[0115] Data source module M101 is used to acquire ultrasound images and image display parameters and primitives corresponding to each ultrasound image;

[0116] The processing module M103 is used to adjust the display effect of the corresponding ultrasound image according to the image display parameters;

[0117] The layout display module M104 is used to determine and load the display layout;

[0118] The ultrasound image display module M105 is used to display the corresponding adjusted ultrasound image at each preset display position in the first layer of the display layout, and to display the graphic elements corresponding to the ultrasound image in the first layer in the second layer of the display layout.

[0119] In any display layout, at least one of the following properties differs from the other display layouts:

[0120] The number of ultrasound images displayed simultaneously, the update status of each ultrasound image displayed simultaneously, and the type of each ultrasound image displayed simultaneously.

[0121] Optionally, the update status includes real-time status and frozen status;

[0122] The image display parameters include at least one of the following:

[0123] Image display area, image imaging depth, image scaling factor, scan speed, baseline setting parameters, focus position, flip state, rotation state.

[0124] Optionally, the medical ultrasound examination instrument further includes:

[0125] The image post-processing module M102 is used to edit the corresponding frozen ultrasound image according to the image editing parameters;

[0126] The image editing parameters include image gain and image dynamic range.

[0127] In practice, the image post-processing module M102 can be connected to other modules via a bridging mechanism.

[0128] Optionally, the ultrasound image display module M105 is specifically used for:

[0129] A first display layout is determined and loaded. An adjusted real-time B-mode ultrasound image and an adjusted real-time C-mode ultrasound image are overlaid in the first area of ​​the first layer of the first display layout. An adjusted real-time PW-mode ultrasound image is displayed in the second area of ​​the first layer of the first display layout. Gray bars, color bars, a scale for representing image imaging depth, a region of interest (ROI), and ultrasound probe position markers are displayed in the second layer of the first display layout.

[0130] Optionally, the image post-processing module M102 is specifically used for:

[0131] Edit the corresponding frozen B-mode ultrasound image according to the image editing parameters;

[0132] The ultrasound image display module M105 is specifically used for:

[0133] A second display layout is determined and loaded. An adjusted real-time B-mode ultrasound image is displayed in the first and second areas of the first layer of the second display layout, and an adjusted frozen B-mode ultrasound image is displayed in the third and fourth areas of the first layer of the second display layout. Grayscale bars, a scale for representing image imaging depth, and ultrasound probe position marks are displayed in the second layer of the first display layout.

[0134] The frozen B-mode ultrasound image in the third region is obtained by freezing the real-time B-mode ultrasound image in the first region, and the frozen B-mode ultrasound image in the fourth region is obtained by freezing the real-time B-mode ultrasound image in the second region.

[0135] Optionally, if the graphic element includes the measurement mark, then the graphic element corresponding to the ultrasound image of the first layer is displayed in the second layer of the display layout, specifically including:

[0136] In the second layer of the display layout, the graphic of the measurement mark is drawn and displayed using the drawing feature points and shape of the measurement mark.

[0137] Optionally, the processing module M103 is further configured to:

[0138] Determine the ultrasound image corresponding to the measurement marker;

[0139] For any ultrasound image corresponding to the measurement mark, the measurement result of the measurement content of the measurement mark in the ultrasound image is calculated according to the image parameters of the ultrasound image, wherein the image parameters include the image display parameters and the image measurement parameters;

[0140] The total measurement result is calculated based on the measurement results of all ultrasound images corresponding to the measurement mark, and the total measurement result is added to the measurement mark;

[0141] Rendering the measurement markers also includes:

[0142] Render the overall measurement results.

[0143] Optionally, the ultrasound image display module M105 is further used for:

[0144] The ultrasound image is saved in the medical image format of the first layer, and the corresponding graphic elements are saved in the medical image format of the second layer; or, the ultrasound image and the corresponding graphic elements are merged into a medical image of the same layer and then saved.

[0145] Save the ultrasound image display parameters, image editing parameters, and image measurement parameters.

[0146] Optionally, measurement marks can be saved in a manner that preserves the drawn feature points and shapes.

[0147] In specific implementation, the medical ultrasound examination instrument embodiments described above are merely illustrative. For example, the module division is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple modules or components may be combined, or some features may be ignored or not executed. The functional modules in the various embodiments of this application can be integrated into one processing module, or each module may exist physically separately, or two or more modules may be integrated into one module. The integrated modules described above can be implemented in hardware or as software functional modules. If the integrated module is implemented as a software functional module and sold or used as an independent product, it can be stored in a computer-readable storage medium.

[0148] For example, in a specific implementation, the layout display module M104 and the processing module M103 can be integrated into a single software functional module—the display logic processing module M130. Figure 7As shown, the display logic processing module M130 is divided into three layers from top to bottom: the external interface layer L1, the logic control layer L2, and the display element layer L3. The external interface layer L1 is mainly responsible for the external application programming interface (API), loading the display layout, managing the display thread, and receiving and distributing messages. The logic control layer L2 is mainly responsible for storing and managing the display layout, including storing and managing the primitives of each page, such as measurement marks and annotations; acquiring ultrasound images and primitives from the data source module M101 and passing them to the underlying display element layer; and receiving and distributing messages. Specifically, the logic control layer L2 consists of three components: a representation component, an abstract component, and a control component. The control component is mainly responsible for logic control and communication with other components or modules; the abstract component is mainly responsible for storing data; and the representation component is mainly responsible for implementing specific display control. Specifically, after the control component of the logic control layer L2 obtains data (including ultrasound image and graphic element data, data size, frame number, timestamp, etc.) from the data source module M101, it stores the data in the abstract component and distributes the data to the ultrasound image display module M105 for rendering and display through the display element layer L3. When the user draws measurement marks or annotations, etc., the data is transmitted to the logic control layer L2 via the external interface layer L1 through a message mechanism. The representation component of the logic control layer L2 obtains and stores the correspondence between the measurement marks or annotations and the ultrasound image (e.g., frame number) from the abstract component. The representation component combines the measurement or annotation data together and distributes it to the ultrasound image display module M105 through the display element layer L3 via the control component for drawing and storing the measurement marks or annotations, etc. The display element layer L3 is mainly responsible for receiving messages distributed from the upper layer, distributing them to various display positions, and controlling the display effect of the ultrasound image and graphic elements. Therefore, after the adjustment of each ultrasound image or graphic element is transmitted to the display logic processing module through the message mechanism, the message is received by the unified interface of the external interface layer L1, and the logic control layer L2 controls which display position of the ultrasound image or graphic element the message flows to. The display element layer L3 transmits the respective parameters to the ultrasound image display module M105 for storage and processing, thereby achieving parameter separation. Furthermore, when displaying medical images, the logic control layer L2 determines whether to transmit the image to the ultrasound image display module M105 for display by judging whether the frame number corresponding to the second type of graphic element is the same as the frame number of the currently displayed ultrasound image, thereby realizing the correspondence between the second type of graphic elements such as measurement lines or annotations and the ultrasound image.
