[0082] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0083] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0084] Mentioning "embodiment" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. It should be understood that in this application, "at least one (item)" means one or more, "multiple" means two or more, and "at least two (items)" means two or three and more.

[0085] In the medical field, after collecting the ultrasonic image of the patient, the ultrasonic image can be displayed, and the relevant personnel can then perform auxiliary diagnosis on the patient based on the displayed ultrasonic image. For example, the patient's lesion and needle insertion point are determined based on the ultrasonic image, and then the puncture path for the lesion can be determined based on the lesion and the needle insertion point. In the case where the ultrasonic acquisition device used to collect the ultrasonic image of the patient and the display device used to display the ultrasonic image are usually matched, the display device has a better display effect on the ultrasonic image collected by the ultrasonic acquisition device (such as the display device can display the ultrasonic image with a suitable resolution). For example, when the ultrasonic acquisition device and the first display device are both owned by the hospital, the hospital can determine the resolution at which the first display device displays the ultrasonic image collected by the ultrasonic acquisition device by calibration, and obtain the desired display effect. However, in the case where the ultrasonic acquisition device and the display device are not matched, it is easy to cause the display device to have a poor display effect on the ultrasonic image collected by the ultrasonic acquisition device. For example, the ultrasonic acquisition device is owned by the hospital, but the display device is not owned by the hospital, which can easily cause the display device to have a poor display effect on the ultrasonic image collected by the ultrasonic acquisition device.

[0086] Based on this, an embodiment of the present application provides a method for displaying an ultrasonic image to determine display parameters of an ultrasonic image acquired by an ultrasonic acquisition device when it is desired to obtain the effect of displaying the ultrasonic image acquired by an ultrasonic acquisition device through a first display device, wherein the display parameters represent the ratio of the distance between two adjacent pixels in the ultrasonic image acquired by the ultrasonic acquisition device to the distance between two adjacent pixels in the display area. The first display device can be understood as the device supporting the ultrasonic acquisition device as described above. The display area can be an area of ​​the display device used to display ultrasonic images, for example, the display area is a display screen of the display device.

[0087] For example, see Figure 1 , Figure 1 A schematic diagram of displaying an ultrasound image in a display area provided in an embodiment of the present application. Figure 1As shown, the ultrasonic image includes pixel A, pixel B, pixel C, pixel D, pixel E, pixel F, pixel G, pixel H, and pixel I. All pixels of the ultrasonic image are located in the display area. Since pixel A is adjacent to pixel B, the distance between pixel A and pixel B in the ultrasonic image is 1 pixel. If the position of pixel A in the display area is p1 and the position of pixel B in the display area is p2, then the position of pixel A and pixel B in the display area is the distance from p1 to p2. The display parameter can be: 1 pixel / distance from p1 to p2.

[0088] Alternatively, since there is a pixel B between pixel A and pixel C, the distance between pixel A and pixel C in the ultrasound image is 2 pixels. If the position of pixel A in the display area is p1, and the position of pixel C in the display area is p3, then the distance between the positions of pixel A and pixel C in the display area is from p1 to p3. The display parameter may be: 2 pixels / distance from p1 to p3.

[0089] After obtaining the display parameters, the resolution of the display device for displaying the ultrasonic image can be determined based on the size of the display area of ​​the display device that needs to display the ultrasonic image acquired by the ultrasonic acquisition device and the display parameters, so as to match the display effect of the display device displaying the ultrasonic image with the effect of the first display device displaying the ultrasonic image.

[0090] The method for displaying an ultrasonic image will be described in detail below. The execution subject of the method for displaying an ultrasonic image in the embodiment of the present application is a display device for an ultrasonic image (hereinafter referred to as a display device), wherein the display device can be any electronic device that can execute the technical solution disclosed in the embodiment of the method of the present application. Optionally, the display device can be one of the following: a mobile phone, a computer, a tablet computer, and a wearable smart device.

[0091] It should be understood that the method embodiment of the present application can also be implemented by a processor executing a computer program code. The following describes the embodiment of the present application in conjunction with the drawings in the embodiment of the present application. Figure 2 , Figure 2 A schematic flow chart of a method for displaying an ultrasound image provided in an embodiment of the present application.

[0092] 201. Acquire a first ultrasound image.

[0093] In the embodiment of the present application, the first ultrasonic image is acquired by an ultrasonic acquisition device, and the first ultrasonic image includes a first target object and a second target object, wherein the first target object and the second target object are different objects. The target object can be any object, for example, the target object is a line, and for example, the target object is a bump.

[0094] In an implementation of acquiring a first ultrasound image, a display device receives the first ultrasound image input by a user through an input component, wherein the input component includes: a mouse, a keyboard, a touch screen, a touch pad, and an audio input device.

[0095] In another implementation method of acquiring the first ultrasonic image, the display device receives the first ultrasonic image sent by a terminal, wherein the terminal includes: a mobile phone, a computer, a tablet computer, and a smart wearable device.

[0096] 202. Determine a first distance between the first target object and the second target object in the first ultrasound image.

[0097] The display device determines the position of the first target object in the first ultrasound image and the position of the second target object in the first ultrasound image, and then determines the distance between the first target object and the second target object in the first ultrasound image based on the two positions, which is the first distance.

[0098] Optionally, the position of the first target object in the first ultrasound image is the coordinates of the first target object in the pixel coordinate system of the first ultrasound image. The position of the second target object in the first ultrasound image is the coordinates of the second target object in the pixel coordinate system of the first ultrasound image.

[0099] In a possible implementation, the display device determines a distance between a center of the first target object and a center of the second target object in the first ultrasound image as the first distance.

[0100] 203. Obtain a second distance.

[0101] In the embodiment of the present application, the second distance represents the distance between the first target object and the second target object in the display area of ​​the first display device when the first ultrasound image is displayed by the first display device. Figure 1 In the example, the display area is the display area of ​​the first display device, the ultrasound image is the first image, the first target object is pixel A, the second target object is pixel B, and the second distance is the distance from p1 to p2.

[0102] In an implementation manner of acquiring the second distance, the display device receives the second distance input by the user through an input component.

[0103] In another implementation of acquiring the second distance, the display device receives the second distance sent by the terminal.

[0104] 204. Determine the display parameter based on the ratio of the first distance to the second distance.

[0105] In the embodiment of the present application, the display parameter represents the ratio of the distance between two adjacent pixels in the ultrasound image acquired by the ultrasound acquisition device to the distance between two adjacent pixels in the display area. Based on the display parameter, it can be determined that when the ultrasound image acquired by the ultrasound acquisition device is displayed in a display area of ​​known size, how many pixels should be used to display the ultrasound image to obtain the effect of the first display device displaying the ultrasound image acquired by the ultrasound acquisition device.

[0106] In the embodiment of the present application, the first ultrasonic image is acquired by an ultrasonic acquisition device, and the first ultrasonic image includes a first target object and a second target object. After the display device determines the first distance between the first target object and the second target object in the first ultrasonic image, and obtains the second distance between the first target object and the second target object in the world coordinate system. Based on the first distance and the second distance, the display parameter of the ultrasonic image acquired by the ultrasonic acquisition device can be determined, wherein the display parameter represents the ratio of the distance between two adjacent pixels in the ultrasonic image acquired by the ultrasonic acquisition device to the distance between two adjacent pixels in the display area.

[0107] As an optional implementation manner, after executing step 204, the display device further executes the following steps:

[0108] 301. Obtain a display size of a display area of ​​a second display device.

[0109] In an embodiment of the present application, the second display device is a display device different from the first display device. In one possible implementation, the ultrasound acquisition device is an ultrasound probe held by the hospital. The first display device is a display device held by the hospital and paired with the ultrasound probe. The desired display effect can be obtained by displaying the ultrasound image acquired by the ultrasound probe on the first display device. The second display device is a display device outside the hospital. For example, when the second display device displays the ultrasound image acquired by the ultrasound probe, relevant personnel outside the hospital can determine the lesion and the needle entry point based on the ultrasound image displayed by the second display device, and then determine the puncture path for the lesion based on the lesion and the needle entry point.

[0110] In the embodiment of the present application, the display size is the size of the display area of ​​the second display device, wherein the display size is the physical size of the display area of ​​the second display device. Optionally, the display size includes the length and width of the display area of ​​the second display device. For example, the display size includes that the length of the display area of ​​the second display device is 80.17 cm and the width of the display area of ​​the second display device is 34.44 cm.

[0111] Optionally, the size of the display area of ​​the second display device is different from the size of the display area of ​​the first display device. Therefore, if the second display device displays the ultrasonic image acquired by the ultrasonic acquisition device, and it is desired to obtain the effect of the second display device displaying the ultrasonic image acquired by the ultrasonic acquisition device, then the resolution of the ultrasonic image acquired by the ultrasonic acquisition device displayed by the second display device (hereinafter referred to as the target resolution) should be different from the resolution of the ultrasonic image acquired by the ultrasonic acquisition device displayed by the first display device (hereinafter referred to as the reference resolution). Therefore, in order to determine the target resolution, it is necessary to first determine the display parameters, and then determine the target resolution based on the display size and display parameters of the display area of ​​the second display device.

[0112] 302. Based on the display size and the display parameters, determine a target resolution for the second display device to display the image acquired by the ultrasound acquisition device.

[0113] As described in step 301, the target resolution is the resolution of the second display device displaying the ultrasound image acquired by the ultrasound acquisition device. Since the ratio of the distance between two adjacent pixels in the first ultrasound image to the distance between two adjacent pixels in the display area of ​​the second display device can be determined based on the display parameters, when the display size of the display area is known, the number of pixels used to display the first ultrasound image can be determined based on the display size and the display parameters, and the effect of the first display device displaying the first ultrasound image can be obtained, thereby determining the target resolution.

[0114] In a possible implementation, the display device determines the quotient of the display size and the display parameter to obtain the target resolution. Optionally, the display device determines the target resolution by the following formula: display size=target resolution×display parameter.

[0115] In one possible implementation, the display parameters include a transverse display parameter and a longitudinal display parameter. The transverse display parameter represents the ratio of the transverse distance between two adjacent pixels in the ultrasound image acquired by the ultrasound acquisition device to the transverse distance between two adjacent pixels in the display area. The longitudinal display parameter represents the ratio of the longitudinal distance between two adjacent pixels in the ultrasound image acquired by the ultrasound acquisition device to the longitudinal distance between two adjacent pixels in the display area. The transverse distance in the display area is the transverse distance of the display area, and the longitudinal distance in the display area is the longitudinal distance of the display area. The transverse direction is a direction parallel to the transverse axis of the pixel coordinate system of the displayed ultrasound image, and the longitudinal direction is a direction parallel to the transverse axis of the pixel coordinate system of the displayed ultrasound image. For example, refer to Figure 3 , Figure 3 Another schematic diagram of displaying an ultrasound image in a display area provided by an embodiment of the present application. Figure 3As shown, the first ultrasonic image includes pixel A, pixel B, pixel C, pixel D, pixel E, pixel F, pixel G, pixel H, and pixel I, wherein all pixels of the first ultrasonic image are located in the display area of ​​the second display device. The pixel coordinate system of the first ultrasonic image is OXY, wherein O is the origin, the X-axis represents the horizontal axis of the pixel coordinate system, and the Y-axis represents the vertical axis of the pixel coordinate system. The direction parallel to the X-axis in the display area of ​​the second display device is the horizontal direction, and the direction parallel to the Y-axis in the display area of ​​the second display device is the vertical direction.

[0116] The display device may determine the horizontal resolution of the target resolution based on the horizontal display parameter and the horizontal size of the display size, wherein the horizontal size is the size of the display area of ​​the second display device in the horizontal direction. The display device may determine the vertical resolution of the target resolution based on the vertical display parameter and the vertical size of the display size, wherein the vertical size is the size of the display area of ​​the second display device in the vertical direction. The target resolution is obtained based on the horizontal resolution of the target resolution and the vertical resolution of the target resolution.

[0117] Optionally, the display device determines the quotient of the horizontal dimension of the display size and the horizontal display parameter to obtain the horizontal resolution of the target resolution. The display device determines the quotient of the horizontal dimension of the display size and the vertical display parameter to obtain the horizontal resolution of the target resolution.

[0118] As an optional embodiment, the above-mentioned display parameters include horizontal display parameters and vertical display parameters. The display device implements "determining the display parameters of the above-mentioned ultrasonic acquisition device based on the above-mentioned first distance and the above-mentioned second distance" by executing the following steps: Determine the first ratio of the above-mentioned second distance to the above-mentioned first distance. Determine the first component of the horizontal coordinate of the above-mentioned first distance in the pixel coordinate system, and the above-mentioned pixel coordinate system is the pixel coordinate system of the image acquired by the above-mentioned ultrasonic acquisition device. Determine the second component of the vertical coordinate of the above-mentioned first distance in the above-mentioned pixel coordinate system. Determine the second ratio of the above-mentioned first component to the length of the image acquired by the above-mentioned ultrasonic acquisition device. Determine the third ratio of the above-mentioned second component to the width of the image acquired by the above-mentioned ultrasonic acquisition device. Based on the above-mentioned first ratio and the above-mentioned second ratio, the above-mentioned horizontal display parameters are obtained. Based on the above-mentioned first ratio and the above-mentioned third ratio, the above-mentioned vertical display parameters are obtained.

[0119] In this embodiment, the display device can determine the horizontal display parameters and the vertical display parameters respectively, thereby more accurately representing the display parameters, which is more conducive to subsequently determining the target resolution for displaying the first ultrasound image based on the display parameters.

[0120] Optionally, after determining the target resolution, the display device displays the first ultrasound image based on the target resolution.

[0121] As an optional implementation manner, the display device performs the following steps during the process of executing step 202:

[0122] 401. Determine, from the first ultrasound image, a first target pixel whose semantics is the first target object.

[0123] 402. Determine, from the first ultrasound image, a second target pixel whose semantics is the second target object.

[0124] 403. Determine the center of the first target pixel to obtain a first center pixel.

[0125] 404. Determine the center of the second target pixel to obtain a second center pixel.

[0126] 405. Obtain the first distance based on the distance between the first center and the second center.

[0127] In this embodiment, after determining the first target pixel of the first target object and the second target pixel of the second target object from the first ultrasonic image, the display device determines the center of the first target pixel to obtain the first center pixel, and determines the center of the second target pixel to obtain the second center pixel. Finally, based on the distance between the first center and the second center, the first distance is obtained. In this way, the first distance between the first target object and the second target object in the first ultrasonic image can be obtained based on the distance between the center of the first target object in the first ultrasonic image and the center of the second target object in the second ultrasonic image.

[0128] In one possible implementation, the display device uses the distance between the first center and the second center as the first distance. In another possible implementation, after determining the distance between the first center and the second center, the display device calculates the sum of the distance and a first preset value to obtain the first distance. In yet another possible implementation, after determining the distance between the first center and the second center, the display device calculates the product of the distance and a second preset value to obtain the first distance.

[0129] As an optional implementation, Figure 4 A schematic diagram of a first ultrasound image provided in an embodiment of the present application. Figure 4 As shown, there are four bright spots A, B, C, and D in the first ultrasound image. The first target object and the second target object can be any two of A, B, C, and D. For example, the first target object is point A, and the second target object is point B.

[0130] Optionally, the line between A and B is parallel to the horizontal axis of the pixel coordinate system of the first ultrasound image, the line between C and D is parallel to the horizontal axis of the pixel coordinate system of the first ultrasound image, the line between A and C is parallel to the vertical axis of the pixel coordinate system of the first ultrasound image, and the line between B and D is parallel to the vertical axis of the pixel coordinate system of the first ultrasound image.

[0131] If point A is taken as the first target and point B is taken as the second target, the first distance is the distance between point A and point B. At this time, the distance is the transverse distance in the first ultrasound image. Correspondingly, the second distance is the transverse distance in the display area. The transverse display parameter can be determined based on the ratio of the first distance to the second distance. Similarly, if point C is taken as the first target and point D is taken as the second target, the transverse display parameter can also be determined based on the ratio of the first distance to the second distance.

[0132] If point A is taken as the first target and point C is taken as the second target, then the first distance is the distance between point A and point C, which is the longitudinal distance in the first ultrasound image. Correspondingly, the second distance is the longitudinal distance in the display area. The longitudinal display parameter can be determined based on the ratio of the first distance to the second distance. Similarly, if point B is taken as the first target and point D is taken as the second target, the longitudinal display parameter can also be determined based on the ratio of the first distance to the second distance.

[0133] As an optional implementation manner, the display device determines the center of the first target pixel to obtain the first center pixel by performing the following steps:

[0134] 501. Select any pixel from the first ultrasound image as a candidate pixel.

[0135] In one possible implementation, the display device selects any pixel from a preset area as a candidate pixel, wherein the preset area is a circular area, the preset area includes a target pixel area, the radius of the preset area is a preset value, and the target pixel area is a pixel area composed of first target pixels. Since in the case where the target pixel area is an irregular shape, the center of the first target pixel may not be within the target pixel area, and there may be pixels other than the first target pixel within the preset area, therefore, any pixel from the preset area is selected as a candidate pixel, and the candidate pixel may be a pixel other than the first target pixel, and further, the first center pixel of the first target pixel determined based on the candidate pixel may be a pixel other than the first target pixel, thereby improving the accuracy of the first center pixel. For example, Figure 5 A schematic diagram of a preset area provided in an embodiment of the present application. Figure 5As shown, the preset area includes a target pixel area, and the shape of the target pixel area is irregular. Moreover, the preset area includes an area other than the target pixel area, that is, the preset area includes pixels other than the first target pixel.

[0136] In another possible implementation, the display device selects any one pixel from the first target pixels as a candidate pixel. The semantics of the first target pixel is the first target object, so the first target pixels are all pixels covered by the first target object in the first ultrasound image. Since the center of the target pixel area (i.e., the first center pixel) has a high probability of being a pixel in the first target pixel, the display device first selects any one pixel from the first target pixels as a candidate pixel, which can increase the speed of subsequently determining the first center pixel based on the candidate pixels.

[0137] Optionally, the display device determines a first average value of the abscissas and a second average value of the ordinates of all first target pixels, and then determines pixels whose abscissas are the first average value and whose ordinates are the second average value as candidate pixels.

[0138] 502. Determine a first vector between the candidate pixel and the first target pixel.

[0139] Specifically, the display device determines the vector of the candidate pixel pointing to the first target pixel to obtain the first vector. Optionally, when the number of the first target pixels is greater than 1, the display device determines the vectors of the candidate pixel and each first target pixel respectively to obtain at least two first vectors.

[0140] 503. Calculate the mean of the sum of the first vectors to obtain a second vector.

[0141] If the average value of the sum of the first vectors represents the average value of the vectors of each pixel in the first target pixel and the candidate pixel with the candidate pixel as the center of the first target pixel, in one possible implementation, the display device first determines the sum of all the first vectors, and then calculates the quotient of the sum and the number of first vectors to obtain the second vector.

[0142] 504. When the modulus of the second vector is less than or equal to a modulus threshold, determine the candidate pixel as the first central pixel.

[0143] Since the modulus of a vector represents the length of the vector, and the second vector represents the average value of the vectors of each pixel in the first target pixel and the candidate pixel, the modulus of the second vector can represent the average value of the distances from each pixel in the first target pixel to the candidate pixel. The smaller the average value of the distances from each pixel in the first target pixel to the candidate pixel, the greater the probability that the candidate pixel is the center pixel of the first target pixel. Therefore, when the modulus of the second vector is small, determining that the candidate pixel is the first center pixel can improve the confidence of the first center pixel.

[0144] In the embodiment of the present application, the display device determines whether the modulus length of the second vector is large or small based on the modulus length threshold. Specifically, if the modulus length of the second vector is less than or equal to the modulus length threshold, it means that the modulus length of the second vector is small, and conversely, if the modulus length of the second vector is greater than the modulus length threshold, it means that the modulus length of the second vector is large. Therefore, when the modulus length of the second vector is less than or equal to the modulus length threshold, the display device determines that the candidate pixel is the first center pixel.

[0145] In this embodiment, the display device selects any one pixel from the first target pixel as a candidate pixel. A first vector of the candidate pixel and the first target pixel is determined. The mean of the sum of the first vectors is calculated to obtain a second vector. When the modulus of the second vector is less than or equal to the modulus threshold, the candidate pixel is determined to be the first center pixel, which can improve the confidence of the first center pixel.

[0146] Optionally, when the modulus of the second vector is greater than the modulus threshold, the display device moves the candidate pixel along the second vector to obtain a new candidate pixel. Then, the candidate pixel is replaced with the new candidate pixel, and the following steps are iteratively performed: determining the first vector of the candidate pixel and the first target pixel, calculating the mean of the sum of the first vectors, obtaining the second vector, until the modulus of the second vector is less than or equal to the modulus threshold, and determining the candidate pixel as the first center pixel.

[0147] As an optional implementation manner, the display device performs the following steps during the process of executing step 501:

[0148] 601. Determine a target pixel area composed of the first target pixels from the first ultrasonic image.

[0149] 602. Based on the shape of the first target object, expand the target pixel area to obtain an expanded pixel area.

[0150] In the embodiment of the present application, the shape of the expanded pixel area matches the shape of the first target object. For example, if the shape of the first target object is circular, then the shape of the expanded pixel area obtained by the display device by executing step 602 is also circular. For another example, if the shape of the first target object is spherical, then the shape of the first target object in the two-dimensional image (i.e., the first ultrasound image) should be circular, so the shape of the expanded pixel area obtained by the display device by executing step 602 is also circular. For another example, if the shape of the first target object is rectangular, then the shape of the expanded pixel area obtained by the display device by executing step 602 is also rectangular.

[0151] 603. The center of the expanded pixel area is used as the candidate pixel.

[0152] Optionally, the display device uses the geometric center of the expanded pixel area as a candidate pixel.

[0153] Since the center of the first target pixel is the center of the first target object in the first ultrasound image, and the shape of the first target object in the first ultrasound image should match the actual shape of the first target object, in this embodiment, the display device first expands the target pixel area based on the shape of the first target object to obtain an expanded pixel area, and then uses the center of the expanded pixel area as a candidate pixel. In this way, the first central pixel is determined based on the candidate pixel, which can reduce the amount of data processing for determining the first central pixel and improve the speed of determining the first central pixel.

[0154] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.
