[0028] In order to make the purpose, technical scheme and advantages of the present invention more obvious, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments described in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the present invention.

[0029] In order to solve the above technical problems, the present invention provides an ultrasonic device. Figure 1 1 is a schematic block diagram of an ultrasound device 100 according to an embodiment of the present invention. Figure 1 As shown, the ultrasound device 100 may include an ultrasound probe 110 and a processing device 120 .

[0030] Exemplarily, the ultrasound device 100 may be an ultrasound device dedicated to musculoskeletal testing, or may be a common ultrasound device with musculoskeletal testing function.

[0031] Exemplarily, the ultrasound probe 110 may be used to acquire a target ultrasound image at a target joint.

[0032] In one embodiment, any ultrasonic probe can be used to collect ultrasonic scanning videos at target joints. The target joints may include any human joints such as finger joints, wrist joints, ankle joints, etc. According to the obtained ultrasonic scanning video, the image corresponding to each frame in the ultrasonic scanning video can be obtained as an ultrasonic image. For example, a 100-frame ultrasonic scanning video can obtain 100 ultrasonic images, and the 100 ultrasonic images are sorted according to the scanning order of the ultrasonic scanning video. The target ultrasonic image may be all or part of the 100 ultrasonic images. For example, at the moment when the ultrasonic scanning video just starts scanning and the scanning is about to end, there may be a situation where the ultrasonic probe is unstable. Therefore, a part of the ultrasonic image located in the middle of the 100 ultrasonic images can be taken as the target ultrasonic image. In one embodiment of the present invention, the target ultrasonic image may be the 45th to 55th ultrasonic image of the 100 ultrasonic images.

[0033] Exemplarily, the processing device 120 can be used to identify the articular side bone area and the synovitis area from the target ultrasound image, and when the synovitis area is identified, determine the level information of the synovitis based on the positional relationship between the synovitis area and the articular side bone area, and the level information is used to indicate the severity of the synovitis; wherein the articular side bone area is the area where the bones are located on both sides of the target joint, and the synovitis area is the area produced by synovial hyperplasia or the area produced by synovial hyperplasia combined with effusion.

[0034] In one embodiment, the processing device 120 can use any type of semantic segmentation model, instance segmentation model and other network models to segment the various regions contained in the target ultrasound image to obtain the joint side bone region and the synovitis region in the target ultrasound image. Among them, the joint side bone region is the region where the bones on both sides of the target joint are located. The target ultrasound image may also include other regions, such as the region where the tendon is located, that is, the tendon region. The synovitis region is the region produced by synovial hyperplasia or the region produced by synovial hyperplasia combined with effusion. In an embodiment of the present invention, if the synovitis region is detected, it can be regarded that the subject has synovitis, and if the synovitis region is not detected, it can be regarded that the subject does not have synovitis. Whether the target ultrasound image contains a synovitis region is uncertain. Therefore, the target ultrasound image can be first identified to determine whether the synovitis region exists. For the target ultrasound image in which the synovitis region is identified, the level information of the synovitis can be determined based on the positional relationship between the synovitis region and the joint side bone region. The level information is used to indicate the severity of synovitis.

[0035] According to the ultrasound device of the embodiment of the present invention, the processing device identifies the joint side bone area and the synovitis area from the target ultrasound image, and when the synovitis area is identified, the level information of synovitis is determined based on the positional relationship between the synovitis area and the joint side bone area. This can reduce the workload of manually determining whether synovitis exists and determining the level information of synovitis when synovitis exists, and the information obtained about synovitis is also more accurate.

[0036] Exemplarily, the processing device can determine the level information of synovitis based on the positional relationship between the synovitis area and the joint-side bone area in the following manner, which may include: determining the bone top line corresponding to the joint-side bone area; determining the target vertex of the synovitis area; and determining the level information of synovitis based on the positional relationship between the bone top line and the target vertex.

[0037] In one embodiment, when the processing device "determines the level information of synovitis based on the positional relationship between the synovitis area and the articular side bone area", it can be implemented by the following operations. Based on the articular side bone area identified from the target ultrasound image, if the identified articular side bone area contains two articular side bone areas, for one of the articular side bone areas, the highest point of the articular side bone area can be determined as the bone vertex corresponding to the articular side bone area. Among them, the side of the articular side bone area close to the synovitis area can be used as the upper side, and the point at the top of the articular side bone area can be used as the highest point. Similarly, for the other articular side bone area, the bone vertex corresponding to the other articular side bone area can also be determined in the same way. Then the line between the two bone vertices is used as the bone top line corresponding to the articular side bone area. If the identified articular side bone area only contains one articular side bone area, the highest point of the area can be used as the bone vertex corresponding to the articular side bone area. Then a straight line is drawn through the bone vertex and in a direction perpendicular to the cross section of the target joint as the bone top line corresponding to the articular side bone area. Based on the synovitis areas identified from the target ultrasound image, if the number of identified synovitis areas is greater than or equal to 1, for each synovitis area, the highest point of the synovitis area can be determined as the vertex of the synovitis area. Among them, the side of the synovitis area away from the joint side bone area can be used as the upper side, and the top point of any synovitis area can be used as the highest point. According to the vertex of each synovitis area determined, the top vertex is used as the target vertex. If the number of identified synovitis areas is 1, the highest point of the area can be directly used as the target vertex of the synovitis area. Then, based on the positional relationship between the bone vertex line and the target vertex, the level information of synovitis can be determined.

[0038] According to the above technical solution, based on the positional relationship between the bone vertex line corresponding to the joint side bone area and the target vertex of the synovitis area, the level information of synovitis can be determined. This method does not require complex judgment criteria, so it has high accuracy and efficiency.

[0039] Exemplarily, the articular side bone region may include a first articular side bone region and a second articular side bone region respectively located on both sides of the target joint. The processing device is also used to identify a joint capsule region from the target ultrasound image, where the joint capsule region is located. The processing device determines the bone top line corresponding to the articular side bone region in the following manner: based on the two endpoints of the joint capsule region in the first direction, two truncation positions corresponding to the two endpoints are determined; based on the two truncation positions, the first articular side bone region and the second articular side bone region are truncated along the second direction to obtain a third articular side bone region and a fourth articular side bone region located on both sides of the target joint; based on the line between the vertices in the third articular side bone region in the second direction and the vertices in the fourth articular side bone region in the second direction, the bone top line is determined; wherein the first direction and the second direction are perpendicular, and the first direction is a direction perpendicular to the cross-section of the target joint.

[0040] Figure 2 FIG. 4 is a schematic diagram showing a target ultrasound image according to an embodiment of the present invention. Figure 2 As shown in the figure, the areas indicated by the two white arrows at the bottom are the joint side bone areas, which may include a first joint side bone area located on the left side of the target joint and a second joint side bone area located on the right side of the target joint. The processing device may also be used to identify the joint capsule area from the target ultrasound image. The joint capsule area is the area where the joint capsule is located. Figure 2 The arrows in the figure show the joint capsule area. Figure 2 The synovitis area is also shown by an arrow. The synovitis area may be contained in the joint capsule area. The way in which the processing device identifies the joint capsule area from the target ultrasound image is similar to the way in which the joint side bone area and the synovitis area are identified, and for the sake of brevity, it will not be repeated here. By way of example and not limitation, any two of the above-mentioned joint side bone area, synovitis area, and joint capsule area may be identified using the same image segmentation network, or may be identified using two different image segmentation networks.

[0041] The processing device determines the bone top line corresponding to the joint side bone region in the following manner: A direction perpendicular to the cross section of the target joint is used as a first direction. A direction perpendicular to the first direction is used as a second direction. Figure 2In the illustrated embodiment, the first direction is the horizontal direction, and the second direction is the vertical direction. Based on the two endpoints of the joint capsule area in the first direction, the first joint side bone area and the second joint side bone area are truncated along the second direction. Exemplarily, the two corresponding truncation positions can be determined based on the two endpoints of the joint capsule area in the first direction, and the first joint side bone area and the second joint side bone area are truncated from the truncation positions. Exemplarily, the distance difference between each of the two truncation positions and the position of the corresponding endpoint can be less than or equal to a preset distance threshold. The preset distance threshold can be set as needed, for example, the threshold can fall within the range of [0,3] mm. That is to say, a position can be taken from the area closer to the position where each endpoint is located as the corresponding truncation position. The following is an example of the truncation position being the position where the endpoint is located. Refer to Figure 2 The two endpoints of the joint capsule region in the first direction are endpoint G 1 and endpoint G 2 . Passing point G 1 and endpoint G 2 Draw two auxiliary lines (such as Figure 2 The third joint side bone region and the fourth joint side bone region located on both sides of the target joint can be obtained by cutting the first joint side bone region. The third joint side bone region is the region closer to the target joint of the two regions obtained by cutting the second joint side bone region. Similarly, the fourth joint side bone region is the region closer to the target joint of the two regions obtained by cutting the second joint side bone region. The vertex in the third joint side bone region in the second direction is C 1 The vertex in the second direction of the bone region on the fourth joint side is C 2 Based on vertex C 1 and vertex C 2 The connection between the two can determine the bone top connection (such as Figure 2 Midpoint C 1 and vertex C 2 white dashed line between them).

[0042] According to the above technical solution, based on the two endpoints of the joint capsule area in the first direction, the first joint side bone area and the second joint side bone area are truncated along the second direction, and the third side bone area and the fourth side bone area near the joint capsule area can be obtained. Since the bone itself may be curved, it may not be accurate to determine the bone top line by taking the vertices of the joint side bone area within a larger range. Therefore, after truncating the joint side bone area using the endpoints of the joint capsule area, the curvature of the bone part in the joint side bone area obtained by truncation will be relatively small, so the determined bone top line is more accurate. This helps to more accurately determine the condition of synovitis.

[0043] Exemplarily, the contour of the synovitis area includes an upper contour and a lower contour, and the dividing point between the upper contour and the lower contour is the two end points of the synovitis area in a first direction, the first direction is a direction perpendicular to the cross-section of the target joint, and the processing device determines the level information of the synovitis based on the positional relationship between the bone vertex line and the target vertex in the following manner, which may include: in the second direction, if the target vertex is below the bone vertex line, it is determined that the synovitis belongs to the first level; in the second direction, if the target vertex is on the bone vertex line or above the bone vertex line, the following determination operation is performed: determine the upper contour of the synovitis area, wherein the target vertex is the contour point at the highest point in the upper contour along the second direction; if the shape of the upper contour is a concave shape, it is determined that the synovitis belongs to the second level; if the shape of the upper contour is a convex shape, it is determined that the synovitis belongs to the third level; wherein the second direction is a direction parallel to the cross-section of the target joint, and the severity corresponding to the first level, the severity corresponding to the second level, and the severity corresponding to the third level increase in sequence.

[0044] In one embodiment, the processing device determines the level information of synovitis based on the positional relationship between the bone vertex line and the target vertex in the following manner. Figure 2 As shown, point H in the synovitis area is the target vertex. In the second direction, if the target vertex is below the bone vertex line ( Figure 2 In another embodiment, if the target vertex is located on the bone vertex line or above the bone vertex line (e.g. Figure 2 If the target vertex H shown in the figure is not found, the processing device can perform the following determination operation. Determine the upper contour of the synovitis area. The contour of the synovitis area may include an upper contour and a lower contour. For example, the contour of the synovitis area can be determined by the Hilbert method or local peak detection, spline fitting, etc. Among them, the upper contour of the synovitis area is the contour between the two endpoints of the synovitis area in the first direction and located in the upper half. For another example, each column of pixel points in the synovitis area located in the second direction can be traversed along the first direction, and the first pixel point in each column of pixel points located in the second direction obtained by the traversal can be used as the contour point of the upper contour of the synovitis area. The upper contour of the synovitis area can be obtained by connecting the contour points of each upper contour. Among them, the target vertex is the contour point in the upper contour that is located at the highest point along the second direction, such as Figure 2Point H shown. According to the morphology of the upper contour of the synovitis area obtained, if the morphology of the upper contour is a concave morphology, it can be determined that the synovitis belongs to the second level. In another embodiment, if the morphology of the upper contour is a convex morphology, it can be determined that the synovitis belongs to the third level. The severity corresponding to the first level, the severity corresponding to the second level, and the severity corresponding to the second level increase in sequence. That is, the severity corresponding to the third level>the severity corresponding to the second level>the severity corresponding to the first level. Exemplarily, any suitable function can be used to perform function fitting on the upper contour, such as performing quadratic function curve fitting. According to the fitting result, it is determined whether the morphology of the upper contour belongs to a concave morphology or a convex morphology. The higher the level, the greater the severity of the synovitis. If the first level indicates that the severity of the synovitis is mild, then the second level indicates that the severity of the synovitis is relatively serious.

[0045] According to the above technical solution, in the second direction, if the target vertex is below the bone vertex line, it can be determined that the synovitis belongs to the first level. If the target vertex is on the bone vertex line or above the bone vertex line, a determination operation can be performed: according to the shape of the upper contour of the synovitis area, it can be determined whether the synovitis area belongs to the second level or the third level. This method can quickly and accurately determine the severity of synovitis, and divide the severity of synovitis into three levels, which is convenient for selecting different solutions for different levels of synovitis.

[0046] Of course, the above-mentioned grading method of synovitis and the number of grading levels are examples rather than limitations of the present invention, and they can be changed as needed.

[0047] Exemplarily, the processing device determines the upper contour of the synovitis area in the following manner: traversing each column of pixel points in the synovitis area located in the second direction along the first direction, and during the traversal process, taking the line formed by the first pixel point in each column of pixel points located in the second direction obtained by the traversal as the upper contour.

[0048] As described above, the first direction (eg Figure 2 The synovitis area is traversed in the vertical direction of the second direction. During the traversal process, the first pixel point in each column of pixel points located in the second direction is obtained as a contour point. Then, the line connecting these points is used as the upper contour.

[0049] According to the above technical solution, the upper contour is obtained by traversing the pixel points of the synovitis area in the second direction along the first direction. The upper contour obtained by this method is relatively accurate and efficient, which can further ensure the accuracy and efficiency of determining the target vertex based on the upper contour.

[0050] Exemplarily, the processing device identifies the joint side bone region and the synovitis region from the target ultrasound image in the following manner: using an image segmentation network to segment the target ultrasound image to identify the joint side bone region and the synovitis region from the target ultrasound image.

[0051] In one embodiment, the target ultrasound image can be segmented using any image segmentation network such as Fully Convolutional Networks (FCN), U-Net, or Pyramid Scene Parseing Network (PSPNet). The joint side bone area and the synovitis area can be identified in the target ultrasound image after image segmentation. Of course, in the above-mentioned embodiment where the joint capsule area needs to be identified, the image segmentation network can be optionally used to identify the joint capsule area at the same time.

[0052] According to the above technical solution, the target ultrasound image is segmented using an image segmentation network to obtain the joint side bone area and the synovitis area. This method is relatively mature and can therefore ensure the efficiency and accuracy of identifying the joint side bone area and the synovitis area.

[0053] Exemplarily, the processing device identifies the joint capsule region from the target ultrasound image in the following manner: using an image segmentation network to segment the target ultrasound image to identify the joint capsule region from the target ultrasound image.

[0054] In one embodiment, an image segmentation network can be used to segment the target ultrasound image to identify the joint capsule region from the target ultrasound image. The image segmentation network has been described in detail in the previous embodiment, and for the sake of brevity, it will not be repeated here. The image segmentation network in this embodiment may be the same as or different from the image segmentation network in the previous embodiment, and the present invention is not limited to this.

[0055] According to the above technical solution, the target ultrasound image is segmented using an image segmentation network to obtain the joint capsule area. This method is relatively mature and can therefore ensure the efficiency and accuracy of identifying the joint capsule area.

[0056] Exemplarily, the ultrasound apparatus may further include a display device for outputting information on whether synovitis exists and outputting level information when synovitis exists.

[0057] In one embodiment, the ultrasound device may also include a display device. The display device may be used to output information about whether synovitis exists and output level information when it exists.
