[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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.

[0047] See also Figure 1 , Figure 1 A flowchart of an ultrasonic three-dimensional image measurement method provided in an embodiment of the present application.

[0048] An ultrasonic three-dimensional image measurement method provided in an embodiment of the present application may include the following steps:

[0049] Step S101: Acquire a target ultrasonic three-dimensional image, and determine a measurement point in the target ultrasonic three-dimensional image.

[0050] In practical applications, a target ultrasonic three-dimensional image can be first obtained, and a measurement point can be determined in the target ultrasonic three-dimensional image. The target ultrasonic three-dimensional image is a target ultrasonic three-dimensional image obtained by scanning with an ultrasonic device. The type of the target ultrasonic three-dimensional image can be determined according to actual needs, and the measurement point is a point on the target ultrasonic three-dimensional image that needs to be measured.

[0051] It should be pointed out that in a specific application scenario, an ultrasonic device can be used to scan the object to be scanned to obtain two-dimensional ultrasonic images frame by frame, and then all two-dimensional ultrasonic images can be three-dimensionally synthesized to obtain a target ultrasonic three-dimensional image.

[0052] In a specific application scenario, when determining the measurement point in the target ultrasonic three-dimensional image, the measurement point can be determined by searching in a large-first-small-later manner, that is, a large-scale area including the measurement point can be determined in the target ultrasonic three-dimensional image first, and then the measurement point can be determined in the large-scale area including the measurement point, etc. Of course, there can be other ways to determine the measurement point, which are not specifically limited in this application.

[0053] Step S102: Obtain and display a parallel cross-sectional view parallel to the visual plane and a depth cross-sectional view perpendicular to the visual plane passing through the measurement point.

[0054] In practical applications, after acquiring a target ultrasonic three-dimensional image and determining a measurement point in the target ultrasonic three-dimensional image, a parallel cross-sectional view parallel to the visual plane and a depth cross-sectional view perpendicular to the visual plane passing through the measurement point can be acquired and displayed. Since both the parallel cross-sectional view and the depth cross-sectional view pass through the measurement point, the corresponding information of the measurement point can be reflected with the help of the parallel cross-sectional view and the depth cross-sectional view.

[0055] It should be pointed out that the visual plane can be determined according to user needs. For example, if the user needs to view the measurement point information on a certain plane, the plane can be used as the visual plane, etc., and if the user does not specify the visual plane, the display plane of the ultrasound device can be used as the visual plane, etc.

[0056] Step S103: obtaining the plane coordinates of the measuring point on the parallel cross-sectional view, and determining the depth position of the measuring point based on the plane coordinates combined with the displayed image of the depth cross-sectional view.

[0057] In practical applications, after obtaining and displaying a parallel cross-sectional view parallel to the visual plane and a depth cross-sectional view perpendicular to the visual plane passing through the measurement point, the plane coordinates of the measurement point on the parallel cross-sectional view can be obtained, and the depth position of the measurement point can be determined based on the plane coordinates combined with the displayed image of the depth cross-sectional view, so as to determine the position information of the measurement point with the help of the plane coordinates and the depth position.

[0058] It should be pointed out that since the ultrasound equipment needs to rely on a three-dimensional coordinate system when constructing a target ultrasound three-dimensional image, the plane coordinates and depth position can be determined based on the three-dimensional coordinate system. Of course, there may be other methods for determining the plane coordinates and depth position, which are not specifically limited in this application.

[0059] The present application provides an ultrasonic three-dimensional image measurement method, which obtains a target ultrasonic three-dimensional image, determines a measurement point in the target ultrasonic three-dimensional image; obtains and displays a parallel cross-sectional view parallel to the visual plane and a depth cross-sectional view perpendicular to the visual plane passing through the measurement point; obtains the plane coordinates of the measurement point on the parallel cross-sectional view, and determines the depth position of the measurement point based on the plane coordinates combined with the displayed image of the depth cross-sectional view. In the present application, after determining the measurement point, a parallel cross-sectional view parallel to the visual plane and a depth cross-sectional view perpendicular to the visual plane passing through the measurement point can be obtained and displayed, so that the user can view the measurement point information carried on the parallel cross-sectional view and the depth cross-sectional view, and the depth position of the measurement point can be determined based on the plane coordinates combined with the displayed image of the depth cross-sectional view, so that the user can determine the position information of the measurement point, thereby improving the user experience.

[0060] See also Figure 2 , Figure 2 This is a flow chart of another ultrasonic three-dimensional image measurement method provided in an embodiment of the present application.

[0061] An ultrasonic three-dimensional image measurement method provided in an embodiment of the present application may include the following steps:

[0062] Step S201: acquiring a target ultrasonic three-dimensional image, and determining a measurement point in the target ultrasonic three-dimensional image, wherein the measurement point includes a plurality of measurement points.

[0063] Step S202: Obtain and display a parallel cross-sectional view parallel to the visual plane and a depth cross-sectional view perpendicular to the visual plane passing through the measurement point.

[0064] Step S203: obtaining the plane coordinates of the measuring point on the parallel cross-sectional view, and determining the depth position of the measuring point based on the plane coordinates combined with the displayed image of the depth cross-sectional view.

[0065] Step S204: Determine the three-dimensional coordinates of the measuring point according to the plane coordinates and the depth position of the measuring point.

[0066] Step S205: determining the distances between the multiple measuring points according to the three-dimensional coordinates of the multiple measuring points.

[0067] In actual applications, when users view ultrasonic three-dimensional images, it is sometimes necessary to measure the distance between two points on the ultrasonic three-dimensional image, and then evaluate the objects reflected by the two points. The existing measurement method is: in the three-dimensional rendering result of the ultrasonic three-dimensional image, determine the projection points of the two points, and use the measurement values ​​of the projection points of the two points in the three-dimensional rendering result as the measurement values ​​of the two points on the ultrasonic three-dimensional image. However, the three-dimensional rendering result is a two-dimensional image. If the measurement values ​​of the projection points of the two points in the three-dimensional rendering result are used as the measurement values ​​of the two points on the ultrasonic three-dimensional image, the measurement value between the two points on the ultrasonic three-dimensional image will be inaccurate, and the ultrasonic three-dimensional image evaluation result will be inaccurate. In order to solve this technical problem, in the present application, after determining the depth position of the measurement point, the three-dimensional coordinates of the measurement point can also be determined according to the plane coordinates and depth position of the measurement point; the distance between multiple measurement points can be determined according to the three-dimensional coordinates of multiple measurement points.

[0068] That is, this embodiment realizes the calculation of the distance between measuring points based on the three-dimensional coordinates of the measuring points, so that the calculated distance corresponds to the three-dimensional coordinates of the measuring points, and the accuracy of the distance value is high. Correspondingly, when the scanning object corresponding to the measuring point is evaluated based on the distance value, the evaluation accuracy can be improved.

[0069] It should be noted that in the present application, in addition to determining the distance between the measuring points, the angle value, circumference, etc. between the measuring points can also be determined, and the specific measurement value can be determined according to actual needs.

[0070] In an ultrasonic three-dimensional image measurement method provided in an embodiment of the present application, since the parallel cross-sectional image is parallel to the visual plane and the depth cross-sectional image is perpendicular to the visual plane, the parallel cross-sectional image and the depth cross-sectional image are perpendicular to each other, and both the parallel cross-sectional image and the depth cross-sectional image pass through the measurement point, so the measurement point can be first determined on the parallel cross-sectional image, and then the depth position can be determined on the depth cross-sectional image based on the information of the measurement point on the parallel cross-sectional image, that is, the plane coordinates of the measurement point on the parallel cross-sectional image are obtained, and the depth position of the measurement point is determined based on the plane coordinates combined with the displayed image of the depth cross-sectional image. Specifically, the process can be as follows: obtaining the plane coordinates of the measurement point on the parallel cross-sectional image; finding a point on the displayed image of the depth cross-sectional image that is consistent with the plane coordinates and falls on the surface of the target ultrasonic three-dimensional image in the depth cross-sectional image based on the plane coordinates, and using the point as the position point of the measurement point on the depth cross-sectional image; and using the depth coordinates of the position point as the depth position of the measurement point.

[0071] In an ultrasonic three-dimensional image measurement method provided in an embodiment of the present application, if the measurement point is on the surface of the target ultrasonic three-dimensional image, the measurement point can be directly determined in the target ultrasonic three-dimensional image, but if the measurement point is not on the surface of the target ultrasonic three-dimensional image, the corresponding measurement point needs to be exposed on the surface of the target ultrasonic three-dimensional image, that is, in the present application, before determining the measurement point in the target ultrasonic three-dimensional image, if the measurement point is not on the surface of the target ultrasonic three-dimensional image, the target three-dimensional image can be cropped so that the measurement point is located on the surface of the cropped target ultrasonic three-dimensional image, and the measurement point is determined. That is, the target ultrasonic three-dimensional image can be cropped so that the measurement point is located on the surface of the cropped target ultrasonic three-dimensional image, and the cropping method can be determined according to actual needs, and the present application does not make specific limitations here, for example, the target ultrasonic three-dimensional image can be cropped multiple times along one direction, etc.

[0072] Specifically, if the measurement point is not on the surface of the target ultrasonic three-dimensional image, the target ultrasonic three-dimensional image can be cropped based on the display image of the parallel cross-sectional view and / or the depth cross-sectional view so that the measurement point is located on the surface of the cropped target ultrasonic three-dimensional image and the measurement point is determined. That is, the target ultrasonic three-dimensional image can be cropped along a direction perpendicular to the parallel cross-sectional view or perpendicular to the depth cross-sectional view. It should be noted that if the target ultrasonic three-dimensional image is cropped along a direction perpendicular to the parallel cross-sectional view, the cropping plane of the cropped target ultrasonic three-dimensional image is parallel to the parallel cross-sectional view, and if the target ultrasonic three-dimensional image is cropped along a direction perpendicular to the depth cross-sectional view, the cropping plane of the cropped target ultrasonic three-dimensional image is parallel to the depth cross-sectional view.

[0073] It should be noted that cropping is only one way of exposing the measurement points on the surface of the target ultrasound three-dimensional image shown in this application. In actual applications, there may be other ways to expose the measurement points on the surface of the target ultrasound three-dimensional image, and this application does not make specific limitations here.

[0074] In an ultrasonic three-dimensional image measurement method provided in an embodiment of the present application, in order to facilitate the display of corresponding information of the measurement point, the target ultrasonic three-dimensional image and the parallel cross-sectional view and depth cross-sectional view of the measurement point can be displayed on the same screen, and the depth cross-sectional view can include a depth cross-sectional view parallel to the bottom plane and a depth cross-sectional view perpendicular to the bottom plane. At this time, each measurement point has three display images on the cross-sectional view to better observe the measurement point. For example, you can follow Figure 3 The manner shown displays the target ultrasonic three-dimensional image and the parallel cross-sectional view and depth cross-sectional view of the measurement point.

[0075] It should be noted that in the present application, in the process of displaying the cross-sectional view of the measurement point, the displayed cross-sectional view may need to be adjusted. In this case, the visual plane can be directly adjusted, and then the ultrasonic three-dimensional image measurement method provided by the present application can be re-executed to update the final displayed cross-sectional view. The adjustment of the visual plane can be determined according to actual needs, for example, the original visual plane can be translated up and down, translated left and right, rotated, etc.

[0076] For ease of understanding, the ultrasonic three-dimensional image measurement method provided by the present application is now described in conjunction with a specific embodiment. Assuming that the visual plane in the present embodiment is a two-dimensional coordinate plane of a three-dimensional coordinate system, such as a plane composed of an x-axis and a y-axis, and the bottom plane is also a two-dimensional plane of a three-dimensional coordinate system, such as a plane composed of a y-axis and a z-axis, and there are two measurement points, then an ultrasonic three-dimensional image measurement method provided in an embodiment of the present application may include the following steps:

[0077] Acquire a target ultrasonic three-dimensional image;

[0078] Determining a first measurement point and a second measurement point in the target ultrasonic three-dimensional image;

[0079] In the target three-dimensional coordinate system, the mutually perpendicular visual plane and bottom plane are determined; it should be pointed out that when the visual plane is a plane composed of the x-axis and the y-axis, the coordinates of the measuring point in the parallel cross-section diagram are the corresponding coordinate values ​​in the three-dimensional coordinates of the measuring point, and when the visual plane is other planes, the three-dimensional coordinates of the measuring point need to be determined according to the relationship between the visual plane and the target three-dimensional coordinate system, that is, if the visual plane is set to the plane composed of the x-axis and the y-axis, the efficiency of determining the three-dimensional coordinates of the measuring point can be improved;

[0080] Determine and display a first parallel cross-sectional view passing through a first measuring point and parallel to a visual plane;

[0081] Determine and display a first depth cross-section through a first measurement point, perpendicular to the visual plane and parallel to the bottom plane;

[0082] Determine and display a second parallel cross-sectional view passing through a second measuring point and parallel to the visual plane;

[0083] Determine and display a second depth cross-sectional view passing through a second measuring point, perpendicular to the visual plane and parallel to the bottom plane;

[0084] Determine a first three-dimensional coordinate based on the coordinates of the first measurement point on the first parallel cross-sectional view and the first depth cross-sectional view;

[0085] The second three-dimensional coordinates are determined based on the coordinates of the second measuring point on the second parallel cross-sectional view and the second depth cross-sectional view. For ease of understanding, the above process is described in conjunction with a graph. Assume that the first measuring point is Figure 4 The second measurement point is Figure 4 Point b in the visual plane is Figure 5 The first depth cross-sectional view can be shown as follows: Figure 6 As shown, the second depth cross-sectional view can be Figure 7 As shown, the positions of the first depth cross-sectional image and the second depth cross-sectional image in the target three-dimensional coordinate system can be as follows: Figure 8 As shown by Figure 8 As shown, the first depth cross-sectional image carries information of a first measurement point, and the second depth cross-sectional image carries information of a second measurement point;
