TECHNICAL FIELD

[0001] The present specification relates to the technical field of medical equipment, and in particular, to an ultrasound imaging method and device. BACKGROUND

[0002] Ultrasound imaging technology can use an ultrasound probe to scan a to-be-imaged part to obtain ultrasound data of the to-be-imaged part. By processing the ultrasound data, an ultrasound image of the to-be-imaged part can be generated.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical solutions of the present application and facilitating the understanding of those skilled in the art. SUMMARY

[0004] Volume ultrasound imaging technology is one of ultrasound imaging technologies, which can perform volume imaging on a to-be-imaged part. Volume ultrasound imaging technology can include three-dimensional (3D) ultrasound imaging technology and four-dimensional (4D) ultrasound imaging technology. Three-dimensional ultrasound imaging technology can perform static three-dimensional imaging on a to-be-imaged part. Four-dimensional ultrasound imaging technology can perform continuous three-dimensional imaging on a to-be-imaged part in the time dimension. In the related art, due to the limitation of device performance, when performing volume ultrasound imaging on a to-be-imaged part, it is necessary to limit the scanning coverage range and concentrate the scanning coverage range on the to-be-imaged part to improve the imaging quality of the to-be-imaged part. The inventors have found that the limited scanning coverage range reduces the field of view range of the volume ultrasound image (for example, a three-dimensional ultrasound image, a four-dimensional ultrasound image), which is not conducive to the understanding of the volume ultrasound image by a doctor.

[0005] To solve at least one of the above technical problems or similar technical problems, the embodiments of the present specification provide an ultrasound imaging method, device and computer program product to facilitate the understanding of the volume ultrasound image by a doctor.

[0006] The embodiments of the present specification provide an ultrasound imaging method, comprising:

[0007] An ultrasound imaging method, characterized in that, comprising:

[0008] According to the two-dimensional ultrasound image of the target part, the anatomical information of the target part is identified;

[0009] The anatomical information is mapped to the volume ultrasound image of the target part;

[0010] The anatomical information is indicated in the volume ultrasound image.

[0011] The embodiment of the present specification further provides an ultrasound imaging device, comprising a processor and a non-transitory memory. The non-transitory memory stores instructions which, when executed, cause the processor to perform the ultrasound imaging method described above.

[0012] The embodiment of the present specification further provides a computer program product, comprising a computer program which, when executed by a processor, implements the ultrasound imaging method described above.

[0013] The technical solution of the embodiment of the present specification contains more surrounding environment information of a target part in a two-dimensional ultrasound image. According to the two-dimensional ultrasound image, the anatomical information of the target part can be quickly and accurately identified. The anatomical information is mapped to a volumetric ultrasound image of the target part. Thus, the volumetric ultrasound image carries the anatomical information identified according to the two-dimensional ultrasound image. By indicating the anatomical information in the volumetric ultrasound image, a doctor can conveniently understand the volumetric ultrasound image (for example, a three-dimensional ultrasound image, a four-dimensional ultrasound image).

[0028] The technical solutions in the embodiments of the present specification will be described clearly and completely below in conjunction with the drawings in the embodiments of the present specification. Obviously, the described embodiments are only some of the embodiments of the present specification, but not all the embodiments. The specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present disclosure. In addition, the relationship terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.

[0029] Figure 1 is a schematic diagram of an ultrasound imaging device in some embodiments of the present specification.

[0030] As Figure 1The ultrasound imaging device 100 can include any one or more of a scanning component 1, a processing component 2, and a display component 3. The scanning component 1 can include an ultrasound probe. The scanning component 1 can emit ultrasound waves to a target site and receive echoes of the ultrasound waves, thereby obtaining ultrasound data of the target site. The processing component 2 can include a processor. The processor can include any one or more of a combination of a central processing unit (CPU), a graphics processing unit (GPU), a microcontroller (MCU), a field-programmable gate array (FPGA), and the like. The processing component 2 can process the ultrasound data to generate an ultrasound image of the target site. The display component 3 can include a display. The display component 3 can display the generated ultrasound image.

[0031] The scanning component 1 can perform a two-dimensional scan on the target site to obtain two-dimensional ultrasound data of the target site. The processing component 2 can generate a two-dimensional ultrasound image of the target site according to the two-dimensional ultrasound data. The display component 3 can display the two-dimensional ultrasound image.

[0032] The scanning component 1 can perform a three-dimensional scan on the target site to obtain volumetric ultrasound data of the target site. The processing component 2 can generate a volumetric ultrasound image of the target site according to the volumetric ultrasound data. The display component 3 can display the volumetric ultrasound image.

[0033] For example, the scanning component 1 can perform a static three-dimensional scan on the target site to obtain three-dimensional ultrasound data of the target site. The processing component 2 can generate a three-dimensional ultrasound image of the target site according to the three-dimensional ultrasound data. The display component 3 can display the three-dimensional ultrasound image. For another example, the scanning component 1 can also perform a continuous three-dimensional scan on the target site in a time dimension to obtain four-dimensional ultrasound data of the target site. The processing component 2 can generate a four-dimensional ultrasound image of the target site according to the four-dimensional ultrasound data. The display component 3 can display the four-dimensional ultrasound image.

[0034] The target site can also be referred to as a site of interest or a site to be imaged. The target site can be an organ or tissue such as a blood vessel, a heart, or a site on an organ or tissue. For example, the target site can be a site on a heart. Specifically, for example, the target site can be a Mitral Valve (MV), a Tricuspid Valve (TV), or the like of a heart.

[0035] In the related art, due to the limitation of device performance, when performing volumetric ultrasound imaging on the target site, it is necessary to limit the scanning coverage range and concentrate the scanning coverage range on the target site to improve the imaging quality of the target site. The inventors have found that the limited scanning coverage range reduces the field of view range of the volumetric ultrasound image, which is not conducive to the understanding of the volumetric ultrasound image by doctors.

[0036] Take four-dimensional ultrasound imaging technology as an example. The four-dimensional ultrasound imaging technology can continuously perform three-dimensional imaging on a target part in a time dimension, and provide more abundant information for doctors. When performing four-dimensional ultrasound imaging on the target part, it is usually necessary to limit the scanning coverage range to concentrate the scanning coverage range on the target part. In this way, the volume rate of the four-dimensional ultrasound image can be improved. The volume rate refers to the amount of volume data that can be obtained per unit time. A higher volume rate can have better real-time performance, and can capture the dynamic process of the target part faster. In this way, the line density of the four-dimensional ultrasound image can also be improved, thereby improving the image quality of the four-dimensional ultrasound image. However, limiting the scanning coverage range will reduce or miss the surrounding environment information of the target part. The surrounding environment information includes the information of the surrounding parts of the target part. The surrounding environment information can help doctors understand the anatomical information of the target part. Due to the reduction or loss of the surrounding environment information of the target part, doctors are difficult to identify the anatomical information of the target part on the four-dimensional ultrasound image, thereby being not conducive to the understanding of the four-dimensional ultrasound image by the doctors.

[0037] To this end, the processing component 2 can identify the anatomical information of the target part according to the two-dimensional ultrasound image of the target part, and map the anatomical information to the volumetric ultrasound image of the target part. The display component 3 can indicate the anatomical information in the volumetric ultrasound image.

[0038] Thus, the two-dimensional (2D) ultrasound image is a planar ultrasound image. The two-dimensional ultrasound image contains more surrounding environment information of the target part. According to the two-dimensional ultrasound image, the anatomical information of the target part can be quickly and accurately identified. The anatomical information is mapped to the volumetric ultrasound image of the target part. Thus, the volumetric ultrasound image carries the anatomical information identified according to the two-dimensional ultrasound image. By indicating the anatomical information in the volumetric ultrasound image, the understanding of the volumetric ultrasound image (such as a three-dimensional ultrasound image, a four-dimensional ultrasound image) by doctors can be facilitated.

[0039] A specific scene example of an embodiment of the present specification is introduced below. The scene example is only for better understanding of the technical solution of the embodiment of the present specification, and does not constitute an improper limitation on the technical solution of the embodiment of the present specification.

[0040] Interventional ultrasound allows imaging during interventional procedures. By placing an ultrasound probe inside the patient's body, it emits ultrasound waves towards the target area and receives the echoes, thus obtaining ultrasound data of the target area. Compared to non-invasive ultrasound, interventional ultrasound uses a probe inside the patient's body, closer to the target area, thereby improving image quality. Taking cardiac ultrasound imaging as an example, non-invasive ultrasound can include TTE (Transthoracic Echocardiography), while interventional ultrasound can include TEE (Transesophageal Echocardiography) and ICE (Intracardiac Echocardiography).

[0041] The inventors discovered that, compared to non-invasive ultrasound, invasive ultrasound uses a probe located inside the patient's body, allowing doctors to identify anatomical information of the target area based solely on ultrasound images, and then move the probe accordingly. However, in 4D ultrasound imaging, it is usually necessary to limit the scanning coverage to improve image quality. This limited coverage reduces the field of view of the 4D ultrasound image. Doctors find it difficult to identify anatomical information on 4D ultrasound images, especially when rotating or slicing the image. This makes it difficult for doctors to know how to move the probe inside the patient's body.

[0042] In this scenario example, the doctor can place an ultrasound probe inside the patient's body and move it to a suitable position within the patient to perform ultrasound imaging on the target area. During this movement, the ultrasound imaging device 100 is in two-dimensional imaging mode, capable of displaying two-dimensional ultrasound images. The doctor can then move the ultrasound probe's position based on these two-dimensional ultrasound images.

[0043] After reaching the appropriate location, the ultrasound imaging device 100 can perform a two-dimensional scan of the target area to obtain two-dimensional ultrasound data of the target area; and can generate a two-dimensional ultrasound image of the target area based on the two-dimensional ultrasound data. The doctor can send a first command to the ultrasound imaging device 100. The first command instructs the ultrasound imaging device 100 to enter four-dimensional imaging mode to perform four-dimensional imaging of the target area. For example, the doctor can send the first command by pressing a button. After receiving the first command, the ultrasound imaging device 100 can perform a continuous three-dimensional scan of the target area in the time dimension to obtain four-dimensional ultrasound data of the target area; and can generate a four-dimensional ultrasound image of the target area based on the four-dimensional ultrasound data. The ultrasound imaging device 100 can identify anatomical information based on the two-dimensional ultrasound image; can map anatomical information to the four-dimensional ultrasound image; and can indicate anatomical information in the four-dimensional ultrasound image. The anatomical information is related to the position and / or scanning direction of the ultrasound probe. The anatomical information can remain unchanged if the position and / or scanning direction of the ultrasound probe remains unchanged. For example, if the doctor zooms or rotates the four-dimensional ultrasound image, the anatomical information indicated in the four-dimensional ultrasound image can follow the zoom or rotation.

[0044] In some scenarios described in this example, the doctor may need to adjust the position of the ultrasound probe to image a new target area. The doctor can send a second command to the ultrasound imaging device 100. The second command instructs the ultrasound imaging device 100 to exit the four-dimensional imaging mode. For example, the doctor can send the second command by pressing a button. After receiving the second command, the ultrasound imaging device 100 can exit the four-dimensional imaging mode and enter the two-dimensional imaging mode, thereby displaying a two-dimensional ultrasound image. The doctor can then move the ultrasound probe to a new, suitable position based on the two-dimensional ultrasound image.

[0045] After reaching the new, suitable position, the doctor can send a first command to the ultrasound imaging device 100. For example, the doctor can send the first command by pressing a button. The first command instructs the ultrasound imaging device 100 to enter four-dimensional imaging mode to perform four-dimensional imaging of the new target area. The process of the ultrasound imaging device 100 performing four-dimensional imaging of the new target area is similar to the process of performing four-dimensional imaging of the target area described above, and therefore will not be repeated. This achieves the adjustment of the ultrasound probe position.

[0046] This specification also provides corresponding ultrasound imaging methods in some embodiments. These ultrasound imaging methods can be used to perform ultrasound imaging on a target area. The target area can also be called a region of interest or the area to be imaged. The target area can be an organ or tissue such as a blood vessel or the heart, or a location on an organ or tissue. For example, the target area can be a location on the heart. Specifically, for example, the target area can be the mitral valve, tricuspid valve, etc. This ultrasound imaging method can be applied to an ultrasound imaging device 100.Figure 2 As shown, the ultrasound imaging method may include the following steps:

[0047] Step 21: Identify the anatomical information of the target area based on the two-dimensional ultrasound image of the target area.

[0048] Step 22: Map the anatomical information to the volumetric ultrasound image of the target site.

[0049] Step 23: Indicate anatomical information in volumetric ultrasound images.

[0050] It should be noted that, Figure 2 This specification only illustrates one possible sequence of steps and does not require strict adherence to this order. For example, some steps can be performed in parallel without interdependence. Based on conventional or non-inventive effort, embodiments of this specification may include more or fewer steps.

[0051] In some embodiments of step 21, the two-dimensional ultrasound image is an ultrasound image of a plane of the target site. The plane can be a two-dimensional ultrasound imaging plane of the target site. The plane can include the surface or section of the target site. The plane can be pre-defined. The number of planes can also be pre-defined. The number of planes can be multiple. Therefore, multiple anatomical information can be identified based on multiple two-dimensional ultrasound images; multiple anatomical information can be mapped to a volumetric ultrasound image of the target site; multiple anatomical information can be indicated in the volumetric ultrasound image. Indicating multiple anatomical information in the volumetric ultrasound image facilitates the doctor's understanding of the volumetric ultrasound image. Multiple different planes can be perpendicular to each other. Multiple different planes can also have other positional relationships. Of course, the number of planes can also be one.

[0052] In some embodiments of step 21, the plane is related to the view of the target site. Different planes can correspond to different viewpoints. The two-dimensional ultrasound image is related to the view of the target site. Different two-dimensional ultrasound images can correspond to different viewpoints. The viewpoint can be used to indicate the position of the ultrasound probe and / or the scanning direction. For example, the target site can be a part of the heart, and the viewpoint of the target site can include the ME_MC (Mid Esophageal-Mitral Commissural) view, the ME_LAX (Mid Esophageal-Long Axis) view, the Bicaval view (a view that simultaneously shows the superior vena cava and inferior vena cava entering the right atrium), and the SAX (Short Axis) view.

[0053] For example, Figure 5In the image (A), the target area is a two-dimensional ultrasound image, and the viewpoint corresponding to this two-dimensional ultrasound image is Bicaval. Figure 5 (B) in the image is another two-dimensional ultrasound image of the target area, and the viewing angle corresponding to this two-dimensional ultrasound image is SAX. Figure 7 In the image (A), the target area is a two-dimensional ultrasound image, and the viewing angle corresponding to this two-dimensional ultrasound image is ME_MC. Figure 7 (B) in the image is another two-dimensional ultrasound image of the target area, and the viewing angle corresponding to this two-dimensional ultrasound image is ME_LAX.

[0054] In some embodiments of step 21, the anatomical information is viewpoint-dependent. Different anatomical information can be identified based on different two-dimensional ultrasound images. The anatomical information is used to represent the anatomical features of the target site. The anatomical information may include at least one of anatomical position information and anatomical subregion information.

[0055] Anatomical information can include one or more anatomical location information. Anatomical location information is used to represent one or more orientations (also known as body positions) of a target body part in space. Anatomical location information can include information used to represent orientation (such as text, patterns, symbols, etc.).

[0056] For example, Figure 3 (A) and (B) in the diagram show the text used to indicate orientation during cardiac ultrasound imaging. Text may include head side, foot side, posterior, anterior, high, low, etc.

[0057] Anatomical information can include one or more anatomical divisions. Anatomical division information is used to represent one or more divisions of the target site. Anatomical division information can include information used to represent the divisions (e.g., text, patterns, symbols, etc.). For example, anatomical division information can include labeling information to identify the divisions. A division can be understood as a sub-region of the target site. By dividing the target site into divisions, it facilitates precise localization by the physician. For example, Figure 4 The partitions of the mitral valve leaflets are shown. Figure 4 In this context, the mitral lobe can include partition A and partition P. Partition A can include partition A1, partition A2, and partition A3. Partition P can include partition P1, partition P2, and partition P3.

[0058] In some embodiments of step 21, the ultrasound imaging device 100 can acquire one or more two-dimensional ultrasound data of the target area; and can generate one or more two-dimensional ultrasound images based on the one or more two-dimensional ultrasound data.

[0059] The ultrasound imaging device 100 can perform two-dimensional scanning of the target area to obtain two-dimensional ultrasound data of the target area. The two-dimensional ultrasound data is the ultrasound data of the target area in a plane.

[0060] The ultrasound imaging device 100 can process (e.g., render) two-dimensional ultrasound data to generate a two-dimensional ultrasound image. The two-dimensional ultrasound image is a planar ultrasound image of the target region.

[0061] When performing a two-dimensional scan of the target area, there is no need to limit the scan coverage. This allows the two-dimensional ultrasound image to have a large field of view, encompassing information about the surrounding environment, including information about the areas surrounding the target area. Thus, the ultrasound imaging device 100 can quickly and accurately identify the anatomical information of the target area based on the two-dimensional ultrasound image.

[0062] In some embodiments of step 21, the ultrasound imaging device 100 can identify one or more anatomical information of the target site based on one or more two-dimensional ultrasound images. The anatomical information may include at least one of anatomical location information and anatomical partition information. The ultrasound imaging device 100 can perform anatomical location identification on the two-dimensional ultrasound images to obtain anatomical location information. The ultrasound imaging device 100 can perform anatomical partition identification on the two-dimensional ultrasound images to obtain anatomical partition information.

[0063] The ultrasound imaging device 100 can identify anatomical information in any manner. Several possible implementation methods are described below.

[0064] In some embodiments of this example, the ultrasound imaging device 100 can input two-dimensional ultrasound images into an image processing model to obtain anatomical information output by the image processing model. The image processing model may include a neural network model, a non-neural network model (e.g., a support vector machine model), etc. The image processing model is used for the identification of anatomical locations and / or the identification of anatomical regions.

[0065] In other embodiments of this example, the ultrasound imaging device 100 can extract anatomical features from two-dimensional ultrasound images; and can obtain anatomical information (e.g., anatomical location information and / or anatomical partition information) of the target site based on the anatomical features.

[0066] The anatomical features of a two-dimensional ultrasound image can include the overall anatomical features of the two-dimensional ultrasound image, or the anatomical features of one or more local regions within the two-dimensional ultrasound image.

[0067] Anatomical features can include shape features (such as area, perimeter, etc.), texture features (such as variance used to represent the uniformity of gray value distribution, entropy used to represent the uncertainty of gray value distribution, etc.), and geometric features (such as inflection points, etc.).

[0068] The ultrasound imaging device 100 can match template images in a template image set based on anatomical features; it can acquire the anatomical information corresponding to the template images. The template image set may include one or more template images. The template images may include pre-generated ultrasound images. The template images correspond to anatomical information. The anatomical information corresponding to the template images can be pre-identified from the template images. The ultrasound imaging device 100 can select template images with the aforementioned anatomical features from the template image set, or it can select template images from the template image set whose corresponding anatomical features are similar to the aforementioned anatomical features.

[0069] In other embodiments of this example, the ultrasound imaging device 100 can identify the viewing angle corresponding to the two-dimensional ultrasound image; and can obtain anatomical information (e.g., anatomical location information and / or anatomical partition information) of the target part based on the viewing angle.

[0070] The ultrasound imaging device 100 can extract anatomical features from two-dimensional ultrasound images; it can obtain a viewing angle based on the anatomical features; and it can obtain anatomical information of the target area based on the viewing angle. The anatomical features of a two-dimensional ultrasound image can include the overall anatomical features of the two-dimensional ultrasound image, or the anatomical features of one or more local regions within the two-dimensional ultrasound image. Anatomical features can include shape features, texture features, geometric features, etc.

[0071] The ultrasound imaging device 100 can query the viewpoints corresponding to anatomical features from a set of viewpoints. The set of viewpoints includes one or more viewpoints of the target site. The viewpoints in the set of viewpoints correspond to anatomical features. For example, if the target site is a part of the heart, the viewpoints of the target site may include the ME_MC (Mid Esophageal-Mitral Commissural, medial-lateral oblique view), the ME_LAX (Mid-Esophageal-Long Axis, medial-lateral long axis view), the Bicaval view (a view that simultaneously shows the superior vena cava and inferior vena cava entering the right atrium), and the SAX (Short Axis) view.

[0072] Of course, the ultrasound imaging device 100 can also use other methods to identify the viewpoint corresponding to the two-dimensional ultrasound image. For example, the ultrasound imaging device 100 can input the two-dimensional ultrasound image into an artificial intelligence model to obtain the viewpoint output by the artificial intelligence model.

[0073] The ultrasound imaging device 100 can query one or more anatomical location information points within a given viewpoint. For example, the ultrasound imaging device 100 can query one or more anatomical location information points corresponding to a viewpoint from a set of anatomical location information. The set of anatomical location information includes one or more anatomical location information points for the target site. The anatomical location information points in the set of anatomical location information correspond to the viewpoint.

[0074] The ultrasound imaging device 100 can perform structural detection on two-dimensional ultrasound images to obtain the anatomical features of one or more zones; it can also query the anatomical zone information corresponding to the anatomical features of a zone under a given viewpoint.

[0075] The ultrasound imaging device 100 can segment two-dimensional ultrasound images using image segmentation algorithms such as Otsu's method to obtain one or more partitions of the two-dimensional ultrasound image; it can extract the anatomical features of the partitions. A partition can be understood as a sub-region of a target area. The anatomical features of a partition include shape features (e.g., area, perimeter, etc.), texture features (e.g., variance used to represent the uniformity of gray value distribution, entropy used to represent the uncertainty of gray value distribution, etc.), and geometric features (e.g., inflection points, etc.). The ultrasound imaging device 100 can query the anatomical partition information corresponding to the anatomical features of the partitions under the viewpoint.

[0076] For example, ultrasound imaging device 100 can query a subset corresponding to a viewing angle from an anatomical partition information set; it can also query one or more anatomical partition information within a subset based on the anatomical features of one or more partitions. The partition information set includes one or more subsets of the target site. The subsets in the partition information set correspond to viewing angles. The subsets include one or more anatomical partition information of the target site. The anatomical partition information in the subset corresponds to the anatomical features of the partitions.

[0077] In some embodiments of step 22, the ultrasound imaging device 100 can acquire volumetric ultrasound data of the target site; and can generate a volumetric ultrasound image of the target site based on the volumetric ultrasound data.

[0078] The ultrasound imaging device 100 can perform three-dimensional scanning of a target area to obtain volumetric ultrasound data of the target area; it can process the volumetric ultrasound data (e.g., rendering) to generate a volumetric ultrasound image of the target area.

[0079] Due to limitations in equipment performance, when performing 3D scanning of a target area, it is necessary to restrict the scanning coverage area and concentrate it on the target area to improve the imaging quality. A limited scanning coverage area reduces the field of view of the volumetric ultrasound image, which is detrimental to the doctor's understanding of the volumetric ultrasound image.

[0080] In some embodiments of this example, volumetric ultrasound data may include three-dimensional ultrasound data. Volumetric ultrasound images may include three-dimensional ultrasound images. The ultrasound imaging device 100 can perform static three-dimensional scanning of the target area to obtain three-dimensional ultrasound data of the target area; and can generate a three-dimensional ultrasound image of the target area based on the three-dimensional ultrasound data. The ultrasound imaging device 100 can process the three-dimensional ultrasound data (e.g., rendering processing) to generate a corresponding three-dimensional ultrasound image.

[0081] Due to limitations in equipment performance, when performing 3D scanning of a target area, it is necessary to restrict the scanning coverage area and concentrate it on the target area to improve the imaging quality. A limited scanning coverage area reduces the field of view of the 3D ultrasound image, which is detrimental to the doctor's understanding of the image.

[0082] In other embodiments of this example, volumetric ultrasound data may include four-dimensional ultrasound data. Volumetric ultrasound images may include four-dimensional ultrasound images. The ultrasound imaging device 100 can perform continuous three-dimensional scanning of the target area in the time dimension to obtain four-dimensional ultrasound data of the target area; and can generate four-dimensional ultrasound images of the target area based on the four-dimensional ultrasound data.

[0083] Four-dimensional ultrasound data comprises multiple ultrasound data volumes, and the combination of multiple ultrasound data volumes constitutes four-dimensional ultrasound data. A four-dimensional ultrasound image comprises multiple image frames. An image frame can be understood as a three-dimensional ultrasound image. The combination of multiple image frames constitutes a four-dimensional ultrasound image. The ultrasound imaging device 100 can process the ultrasound data volumes (e.g., rendering processing) to generate image frames.

[0084] Due to limitations in equipment performance, when performing 3D scanning of a target area, it is necessary to restrict the scanning coverage area and concentrate it on the target area to improve the imaging quality. A limited scanning coverage area reduces the field of view of the 4D ultrasound image, which is detrimental to the doctor's understanding of the 4D ultrasound image.

[0085] For example, Figure 5 (A) in the image is a two-dimensional ultrasound image of a plane at the target site. Figure 6 In the image, (A) represents the ultrasound image corresponding to that plane in a four-dimensional ultrasound image. Compared to... Figure 5 (A) in the middle Figure 6 (A) has a smaller field of vision. Figure 5 (B) in the image is a two-dimensional ultrasound image of another plane of the target area. Figure 6 In the image, (B) represents the ultrasound image corresponding to that plane in a four-dimensional ultrasound image. Compared to... Figure 5 (B) in the middle Figure 6 (B) has a smaller field of vision.

[0086] For example, Figure 7 (A) in the image is a two-dimensional ultrasound image of a plane at the target site. Figure 8 In the image, (A) represents the ultrasound image corresponding to that plane in a four-dimensional ultrasound image. Compared to... Figure 7 (A) in the middle Figure 8 (A) has a smaller field of vision. Figure 7 (B) in the image is a two-dimensional ultrasound image of another plane of the target area. Figure 8 In the image, (B) represents the ultrasound image corresponding to that plane in a four-dimensional ultrasound image. Compared to... Figure 7 (B) in the middle Figure 8 (B) has a smaller field of vision.

[0087] In some embodiments of step 22, the ultrasound imaging device 100 may map one or more anatomical pieces of information onto a volumetric ultrasound image. Thus, the volumetric ultrasound image carries the anatomical information identified from one or more two-dimensional ultrasound images.

[0088] The plane corresponding to the two-dimensional ultrasound image is contained within the three-dimensional space corresponding to the volumetric ultrasound image. Therefore, the ultrasound imaging device 100 can select one or more first regions in the volumetric ultrasound image based on one or more two-dimensional ultrasound images; acquire first marker information for indicating anatomical information; and add first marker information to one or more first regions.

[0089] Users can pre-set first marker information in the ultrasound imaging device 100. The ultrasound imaging device 100 can obtain the user-preset first marker information. Alternatively, the ultrasound imaging device 100 can also obtain the default first marker information.

[0090] The ultrasound imaging device 100 can add first marking information as a label to a first region. Alternatively, the first region may include multiple voxels. The ultrasound imaging device 100 can adjust the values ​​of one or more voxels in the first region based on the first marking information.

[0091] The first marking information may include information used to indicate anatomical information (e.g., text, patterns, symbols, etc.). The first marking information may include the anatomical information itself. Alternatively, the first marking information may also include other information.

[0092] The first marking information may include at least one of location marking information and partition marking information.

[0093] Location marking information is used to indicate anatomical location information.

Location marking information may include the anatomical location information itself. Alternatively, location marking information may include other information. Zoning marking information is used to indicate anatomical zoning information. Zoning marking information includes information used to indicate anatomical zoning information (e.g., text, patterns, symbols, etc.). Zoning marking information may include the anatomical zoning information itself. Alternatively, zoning marking information may include other information.

[0094] In some embodiments of this example, the two-dimensional ultrasound image is related to the viewing angle of the target area. Different two-dimensional ultrasound images can correspond to different viewing angles. The ultrasound imaging device 100 can identify the viewing angle corresponding to the two-dimensional ultrasound image; it can select the spatial region corresponding to the viewing angle in the volumetric ultrasound image as a first region. The spatial region corresponding to the viewing angle can be a two-dimensional plane. In other embodiments of this example, the ultrasound imaging device 100 can input the two-dimensional ultrasound image and the volumetric ultrasound image into an artificial intelligence model to obtain a volumetric ultrasound image with added first labeling information. The artificial intelligence model is used to select the corresponding first region in the volumetric ultrasound image based on the two-dimensional ultrasound image and add the first labeling information to the first region.

[0095] In some embodiments of this example, the volumetric ultrasound image may include a three-dimensional ultrasound image. The ultrasound imaging device 100 may select a spatial region corresponding to the two-dimensional ultrasound image in the three-dimensional ultrasound image as a first region; may acquire first marker information for indicating anatomical information; and may add first marker information to the first region.

[0096] In some examples, the ultrasound imaging device 100 can select a first region in a three-dimensional ultrasound image based on a two-dimensional ultrasound image; first labeling information can be added to the first region. The ultrasound imaging device 100 can add the first labeling information as a tag to the first region. Alternatively, the first region may comprise multiple voxels. The ultrasound imaging device 100 can adjust the values ​​of one or more voxels in the first region based on the first labeling information. In other examples, the ultrasound imaging device 100 can input two-dimensional and three-dimensional ultrasound images into an artificial intelligence model to obtain a three-dimensional ultrasound image with the first labeling information added. The artificial intelligence model is used to select a first region in the three-dimensional ultrasound image based on the two-dimensional ultrasound image and add the first labeling information to the first region.

[0097] In other embodiments of this example, the volumetric ultrasound image may include a four-dimensional ultrasound image. A four-dimensional ultrasound image may include multiple image frames. An image frame can be understood as a three-dimensional ultrasound image. The ultrasound imaging device 100 may select a spatial region corresponding to a two-dimensional ultrasound image as a first region from one or more image frames; may acquire first marker information for indicating anatomical information; and may add first marker information to the first region.

[0098] In some examples, the ultrasound imaging device 100 can select a first region in an image frame based on a two-dimensional ultrasound image; first labeling information can be added to the first region. The ultrasound imaging device 100 can add the first labeling information as a tag to the first region. Alternatively, the first region may include multiple voxels. The ultrasound imaging device 100 can adjust the values ​​of one or more voxels in the first region based on the first labeling information. In other examples, the ultrasound imaging device 100 can input a two-dimensional ultrasound image and an image frame into an artificial intelligence model to obtain an image frame with the first labeling information added. The artificial intelligence model is used to select the corresponding first region in the image frame based on the two-dimensional ultrasound image and add the first labeling information to the first region.

[0099] In some embodiments of step 23, the ultrasound imaging device 100 can display a volumetric ultrasound image with added first marker information. The physician can obtain anatomical information about the target site from the first marker information on the volumetric ultrasound image.

[0100] Anatomical information is related to the position and / or scanning direction of the ultrasound probe. When the position and / or scanning direction of the ultrasound probe remain unchanged, the anatomical information can remain unchanged, and the first marker information can remain unchanged. For example, when a physician zooms or rotates the volumetric ultrasound image, the ultrasound imaging device 100 can make the first marker information zoom or rotate accordingly.

[0101] In some embodiments of this example, the volumetric ultrasound image includes a three-dimensional ultrasound image. The ultrasound imaging device 100 can display a three-dimensional ultrasound image with added first marker information. In other embodiments of this example, the volumetric ultrasound image includes a four-dimensional ultrasound image. The ultrasound imaging device 100 can display one or more image frames with added first marker information.

[0102] For example, the first marking information may include anatomical location information. Figure 5 (A) and (B) are two two-dimensional ultrasound images of the target area. These two two-dimensional ultrasound images correspond to two different viewpoints. These two different viewpoints are perpendicular to each other. The ultrasound imaging device 100 can... Figure 5 (A) identifies anatomical location information such as the head side and foot side; it can be based on... Figure 5(B) identifies anatomical location information posterior and anterior. Figure 5 (C) in the image represents a frame from a four-dimensional ultrasound image of the target area. The image frame includes location markers for the head side, foot side, posterior, and anterior sides. Figure 6 (A) in the image frame corresponds to Figure 5 Two-dimensional ultrasound images from the perspective of (A) in the image. Figure 6 (B) in the image frame corresponds to Figure 5 Two-dimensional ultrasound images from the perspective of (B) in the image.

[0103] For example, the first marking information may include anatomical location information and anatomical partition information. Figure 7 (A) and (B) are two two-dimensional ultrasound images of the target area. These two two-dimensional ultrasound images correspond to two different viewpoints. These two different viewpoints are perpendicular to each other. The ultrasound imaging device 100 can... Figure 7 (A) identifies anatomical location information on the cephalic and pediceal sides, as well as anatomical division information ① and ②; it can be based on Figure 7 (B) identifies the posterior and anterior anatomical location information, as well as anatomical partition information ③ and ④. Figure 7 (C) in the image is a frame in the four-dimensional ultrasound image of the target area. The image frame includes positional markings such as head side, foot side, posterior and anterior, as well as zonal markings such as ①, ②, ③ and ④. Figure 8 (A) in the image frame corresponds to Figure 7 Two-dimensional ultrasound images from the perspective of (A) in the image. Figure 8 (B) in the image frame corresponds to Figure 7 Two-dimensional ultrasound images from the perspective of (B) in the image.

[0104] In some embodiments, the ultrasound imaging device 100 can be used in conjunction with a digital subtraction angiography (DSA) fluoroscopic imaging device. A DSA fluoroscopic imaging device is a medical device that uses X-rays and DSA technology for imaging. In a cardiac catheterization laboratory, the ultrasound imaging device 100 can be used in conjunction with the DSA fluoroscopic imaging device during interventional procedures. The physician can combine the ultrasound images from the ultrasound imaging device 100 with the DSA fluoroscopic images from the DSA fluoroscopic imaging device to clearly observe parts of the patient's body. The DSA fluoroscopic images generated by the DSA fluoroscopic imaging device are two-dimensional (2D) images.

[0105] When the ultrasound imaging device 100 is used in conjunction with a DSA fluoroscopic imaging device, the ultrasound probe of the ultrasound imaging device 100 can be located inside the patient's body. The DSA fluoroscopic image can include the ultrasound probe corresponding to the two-dimensional ultrasound image. The DSA fluoroscopic image can correspond to the two-dimensional ultrasound image. The DSA fluoroscopic imaging device can generate a DSA fluoroscopic image of the target area. The ultrasound imaging device 100 can map anatomical information to the DSA fluoroscopic image of the target area. The ultrasound imaging device 100 can indicate anatomical information in the DSA fluoroscopic image. The DSA fluoroscopic imaging device can also indicate anatomical information in the DSA fluoroscopic image. Thus, by indicating anatomical information in the DSA fluoroscopic image, it facilitates the doctor's understanding of the DSA fluoroscopic image.

[0106] The DSA fluoroscopic imaging device can send DSA fluoroscopic images to the ultrasound imaging device 100. The ultrasound imaging device 100 can acquire the DSA fluoroscopic images sent by the DSA fluoroscopic imaging device. The ultrasound imaging device 100 can also send DSA fluoroscopic images carrying anatomical information to the DSA fluoroscopic imaging device, so that the DSA fluoroscopic imaging device can indicate the anatomical information in the DSA fluoroscopic images.

[0107] Ultrasound imaging device 100 can add second marking information to DSA fluoroscopic images to indicate anatomical information. Ultrasound imaging device 100 and / or DSA fluoroscopic imaging device can display DSA fluoroscopic images with the added second marking information. The second marking information includes information indicating anatomical information (e.g., text, patterns, symbols, etc.). The second marking information may include the anatomical information itself. Alternatively, the first marking information may also include other information. The second marking information may include at least one of location marking information and zonal marking information. The second marking information may be the same as or different from the first marking information.

[0108] The ultrasound imaging device 100 can acquire second marker information; it can add second marker information to DSA fluoroscopic images.

[0109] In some examples, the ultrasound imaging device 100 can receive second marker information from the DSA fluoroscopic imaging device. For example, a user can preset the second marker information in the DSA fluoroscopic imaging device. The DSA fluoroscopic imaging device can obtain the user-preset second marker information and can send the second marker information to the ultrasound imaging device 100. Alternatively, the DSA fluoroscopic imaging device can also obtain default second marker information and can send the second marker information to the ultrasound imaging device 100. In other examples, the ultrasound imaging device 100 can obtain default second marker information.

[0110] The ultrasound imaging device 100 can select a second region in a DSA fluoroscopic image based on the ultrasound probe; it can add second marking information to the second region. The ultrasound imaging device 100 can detect the area where the ultrasound probe is located in the DSA fluoroscopic image as the second region. The ultrasound imaging device 100 can add the second marking information as a label to the second region. Alternatively, the second region may comprise multiple pixels. The ultrasound imaging device 100 can adjust the values ​​of one or more pixels in the second region based on the second marking information.

[0111] Figure 9 (A) shows two two-dimensional ultrasound images of the target site. Figure 9 (B) shows a DSA fluoroscopic image. The DSA fluoroscopic image includes positional markings for the head, feet, back, and front.

[0112] In some embodiments, the ultrasound imaging device 100 may indicate anatomical information identified based on a two-dimensional ultrasound image in a two-dimensional ultrasound image. For example, the ultrasound imaging device 100 may display a two-dimensional ultrasound image with added third marker information.

[0113] The third marking information includes information used to indicate anatomical information. The third marking information may include the anatomical information itself. Alternatively, the third marking information may include other information. The third marking information may include at least one of location marking information and zonal marking information. The third marking information may be the same as or different from the first marking information.

[0114] The technical solutions of the embodiments in this specification refer to two-dimensional ultrasound images, which are planar ultrasound images. Two-dimensional ultrasound images contain a significant amount of surrounding environmental information about the target area. Anatomical information of the target area can be quickly and accurately identified based on the two-dimensional ultrasound image. This anatomical information is then mapped to a volumetric ultrasound image of the target area. Thus, the volumetric ultrasound image carries the anatomical information identified from the two-dimensional ultrasound image. By indicating the anatomical information in the volumetric ultrasound image, it is easier for doctors to understand the volumetric ultrasound image (e.g., three-dimensional ultrasound image, four-dimensional ultrasound image).

[0115] Some embodiments of this specification also provide a medical imaging system. Figure 11 This is a schematic diagram of the architecture of a medical imaging system.
