[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] When displaying the parameter information of the segmented follicle body data through the display interface of the host computer, since there are many follicles recognized, the information of some follicles cannot be displayed on the display interface of the host computer, which is not conducive to doctors' viewing and analysis.

[0059] For this reason, the embodiments of this application propose a follicle repositioning scheme, which can quickly reposition the target follicle to be viewed to the target position on the display interface of the host computer, so as to facilitate viewing and analysis.

[0060] Based on this, the embodiments of this application disclose a follicle repositioning method. This method can be applied to electronic devices such as ultrasonic devices. Further, this method can be applied to the host computer (also called the ultrasonic main machine) of the ultrasonic device.

[0061] See Figure 1 As shown, the method includes:

[0062] Step S11: Determine a target follicle from several follicles displayed on the current host computer display interface; wherein, the target follicle is composed of multiple volume elements.

[0063] See Figure 2 As shown Figure 2 is a schematic diagram of the host computer display interface. In addition to displaying the follicle image in the middle part, the host computer display interface also displays relevant parameters. Figure 2 The various parameters on it are mainly composed of two parts. Among them, the first part is the image parameter selection area, including: FR: accuracy rate; D: depth; Gn: gain; QualMax: image quality; 2DuS / 3DuS: false color. The second part is the follicle measurement result, including: d(V): diameter; dx: length in the x direction; dy: length in the y direction; dz: length in the z direction; md: average length; V: volume.

[0064] In this embodiment, the host computer display interface contains several follicles, and each follicle corresponds to a follicle information, which can be a kind of label information of the follicle. In this way, the user can input the follicle information on the host computer display interface to select the corresponding target follicle.

[0065] In a specific implementation manner, the follicle information input by the user can be obtained through a preset interaction interface on the current host computer display interface. Further, the target follicle is determined from several follicles displayed on the host computer display interface according to the follicle information. In another specific implementation manner, the target follicle can also be determined based on the result selected by the user from the host computer display interface through a preset input device, where the preset input device can be a mouse, a trackball, etc. That is, the host computer receives the user's operation through a mouse, a trackball, etc. to select the target follicle from the follicles displayed on the interface.

[0066] In addition, it should be noted that the target follicle is composed of several volume elements, and this volume element is also called volumetric data or volume data.

[0067] Step S12: Determine a target sample matrix corresponding to the target follicle; the target sample matrix contains the three-dimensional coordinates of each volume element of the target follicle in the first space coordinate system.

[0068] In this embodiment, first, a sample matrix corresponding to each follicle is constructed. Further, the target sample matrix corresponding to the target follicle is determined in the sample matrix.

[0069] The specific process of constructing a sample matrix corresponding to each follicle is as follows: Collect the target body data of the hypoechoic area or cystic area; the target body data contains several follicles, and the volume elements in the same follicle have the same label information; save the three-dimensional coordinates of the volume elements with the same label information in the first space coordinate system into the same sample matrix to obtain the sample matrix corresponding to each follicle respectively.

[0070] In a specific implementation manner, when the ultrasonic device scans the abdomen of the target object, the ultrasonic probe is directed towards the ovarian area, and at this time, the ultrasonic probe collects the ultrasonic echo data of the corresponding area. The ultrasonic host determines the data of the hypoechoic area or cystic area from the ultrasonic echo data collected by the probe based on the follicle volume measurement function. The hypoechoic area and the cystic area are the areas where the follicles are located. Further, the ultrasonic host traverses the target body data. Since the volume elements of the same follicle have the same label information, the ultrasonic host saves the three-dimensional coordinates of the volume elements with the same label information into the same sample matrix, and the sample matrix corresponding to each follicle can be obtained.

[0071] Since each follicle corresponds to a separate sample matrix, after the target follicle is determined, the target sample matrix of the target follicle can be determined from each sample matrix.

[0072] See Figure 3 as shown Figure 3 is a schematic diagram of the point set of a follicle. It can be seen that the follicle is composed of several volume elements. Figure 4 is a schematic diagram of a sample matrix. Each row in the sample matrix stores a sample. It can be seen that the sample matrix is an n×3-dimensional matrix, where n represents the number of volume elements, and 3 represents 3 features, which are the X coordinate value, the Y coordinate value, and the Z coordinate value respectively.

[0073] Step S13: Centralize the three-dimensional coordinates to obtain the centralized processing result, and calculate the eigenvalues and eigenvectors according to the centralized processing result to obtain the target mapping relationship.

[0074] In this embodiment, first, the three-dimensional coordinates are centralized to obtain the centralized processing result, which can represent the central point characteristics corresponding to the target follicle, etc.; then, the eigenvalues and eigenvectors corresponding to the three-dimensional coordinates are calculated according to the centralized processing result to obtain the target mapping relationship. Among them, the target mapping relationship is the mapping relationship required to map the target sample matrix to a new sample matrix.

[0075] Step S14: Map the target sample matrix to a new sample matrix through the target mapping relationship, and determine the characteristic description values of the matrix elements in each column of the new sample matrix to construct the second space coordinate system based on the characteristic description values.

[0076] In this embodiment, first, the target sample matrix is mapped to a new sample matrix through the target mapping relationship, and then the characteristic description values of the column matrix elements in the new sample matrix are determined to construct the second space coordinate system based on the characteristic description values. Among them, the characteristic description value is a value used to characterize the characteristics of a column matrix element, and can be an extreme value, a maximum or minimum value, the difference between extreme values, the sum of extreme values, the difference between maximum and minimum values, the sum of maximum and minimum values, etc.

[0077] Furthermore, since the second space coordinate system is obtained based on the centering processing result of the three-dimensional coordinates of the target follicle, it can be understood as a space coordinate system constructed with the target follicle as the center; the origin of this second space coordinate system can be the center of the target follicle, and the coordinate axes correspond to the major and minor axes of the target follicle. That is, in the second space coordinate system, the target follicle is in a centered position and in a proper posture.

[0078] Specifically, the characteristic description values are the maximum value and the minimum value. In this embodiment, first, the sum values of the maximum value and the minimum value of the column matrix elements in the new sample matrix are determined to obtain three sum values, and the target center point is calculated based on the three sum values, and then the target center point is determined as the origin of the second space coordinate system. Furthermore, in this embodiment, the difference values between the maximum value and the minimum value of the column matrix elements are determined to obtain three difference values, and three vectors are determined based on the three difference values, and then the three vectors are determined as the three coordinate axis vectors of the second space coordinate system.

[0079] In a specific implementation manner, the maximum value of the column matrix elements in the new sample matrix is (X max , Y max , Z max ), and the minimum value of the column matrix elements is (X min , Y min , Z min ). In this way, the three sum values mentioned above are: (X max + X min ), (Y max + Y min ), (Z max + Z min ). In this embodiment, the point where half of the three sum values are located is determined as the target center point, that is, the origin of the second space coordinate system. Specifically, the origin of the second space coordinate system is {(X max + X min ) / 2, (Y max + Y min ) / 2, (Z max + Z min ) / 2}.

[0080] In a specific implementation manner, the maximum value of the column matrix elements in the new sample matrix is (X max , Ymax , Z max ), the minimum value of each column matrix element is (X min , Y min , Z min ). In this embodiment, the vector constructed by the difference between the maximum value X max and the minimum value X min is determined as the X-axis vector of the second space coordinate system, and the vector constructed by the difference between the maximum value Y max and the minimum value Y min is determined as the Y-axis vector of the second space coordinate system, and the vector constructed by the difference between the maximum value Z max and the minimum value Z min is determined as the Z-axis vector of the second space coordinate system.

[0081] Step S15: Determine the transformation matrix according to the positional relationship between the first space coordinate system and the second space coordinate system, and perform pose transformation on the target follicle in the first space coordinate system according to the transformation matrix, so as to relocate the target follicle to the target position on the host computer display interface.

[0082] Among them, the transformation matrix includes a translation matrix and a rotation matrix. Performing pose transformation on the target follicle in the first space coordinate system according to the transformation matrix can be to perform translation and / or rotation transformation on the target follicle in the first space coordinate system to relocate the target follicle to the target position in a specific posture.

[0083] In this embodiment, a translation matrix is constructed according to the positional relationship between the origin of the second space coordinate system and the first space coordinate system, and a rotation matrix is constructed according to the positional relationship between the three coordinate axis vectors of the second space coordinate system and the first space coordinate system.

[0084] Specifically, by translating the origin of the second space coordinate system to the origin of the first space coordinate system, the translation matrix is obtained. It can be understood that in the translation matrix, the distance that each volume element needs to be translated is recorded. Based on this, the center of the target follicle can be translated from the current position to the target position, and the translation of other points in the target follicle can also be realized synchronously, thereby realizing the overall translation of the target follicle.

[0085] Specifically, by rotating the three coordinate axis vectors to the first space coordinate system, the rotation matrix is obtained. It can be understood that after translating the target follicle to the target position, the target follicle can be rotated to the upright position through the rotation matrix, so as to more intuitively display the target follicle on the host computer display interface.

[0086] Among them, the target position of the host computer display interface can be a certain coordinate in the interface. The first spatial coordinate system is the spatial coordinate system where the target position is located, and the second spatial coordinate system is the orthotopic coordinate system where the target follicle is located before transformation. In a specific implementation manner, the target position is the center of the display interface. In this way, the first spatial coordinate system is the coordinate system where the center of the display interface is located. The purpose of this application is to transform the posture and position of the target follicle from the posture and position in the second spatial coordinate system to the posture and position in the first spatial coordinate system. Since the first spatial coordinate system is located at the center of the display interface, the target follicle can be more intuitively observed by repositioning the target follicle in this application.

[0087] Furthermore, when the center of the target follicle is at the center of the display interface, the target follicle is in a centered position in each section. Further, the host computer can perform section division on the target follicle with each coordinate plane corresponding to the first spatial coordinate system as the section plane, and the origin of the first spatial coordinate system corresponds to the intersection point (i.e., the section center) of each section plane. Through the above translation process, the center of the target follicle can be moved to the section center, and through the above rotation process, it can be ensured that the target follicle is the best observation plane on each coordinate plane, so as to more intuitively display the target follicle in the host computer display interface.

[0088] Figure 5 Schematic diagram for transforming the posture and position of the target follicle. From Figure 5 It can be seen that after the target follicle is transformed in the first spatial coordinate system, its orientation is easier to observe. That is to say, in this embodiment, a second spatial coordinate system is established at the position of the target follicle before transformation, and a first spatial coordinate system is established at the target position of the host computer display interface, such as the center of the host computer display interface. Then, the transformation matrix is determined based on the relationship between the second spatial coordinate system and the first spatial coordinate system. Further, the target follicle is repositioned to the target position according to the transformation matrix for intuitive display.

[0089] Furthermore, after repositioning the target follicle to the target position of the host computer display interface, this application can also calculate the three diameters of the target follicle in the first spatial coordinate system. Specifically, the absolute value of the difference between the maximum value and the minimum value of the matrix elements in each column of the new sample matrix is respectively determined as the three diameters of the target follicle, and the three diameters of the target follicle are sent to the host computer display interface for display. In this way, this application can observe the three diameters of the target follicle through the host computer display interface to analyze the target follicle based on the three diameters.

[0090] It can be seen that the present application proposes a follicle repositioning method, including: determining a target follicle from several follicles displayed on the current host computer display interface; wherein, the target follicle is composed of multiple volume elements; determining a target sample matrix corresponding to the target follicle; the target sample matrix contains the three-dimensional coordinates of each of the volume elements of the target follicle in the first space coordinate system; centralizing the three-dimensional coordinates to obtain a centralized processing result, and calculating eigenvalues and eigenvectors according to the centralized processing result to obtain a target mapping relationship; mapping the target sample matrix to a new sample matrix through the target mapping relationship, and determining the characteristic description values of the matrix elements in each column of the new sample matrix, so as to construct a second space coordinate system based on the characteristic description values; determining a transformation matrix according to the positional relationship between the first space coordinate system and the second space coordinate system, and performing a pose transformation on the target follicle in the first space coordinate system according to the transformation matrix, so as to reposition the target follicle to the target position on the host computer display interface. In summary, it can be seen that the present application first determines a target follicle from several follicles displayed on the current host computer, and determines the target sample matrix of the target follicle. Further, the present application obtains a target mapping relationship by centralizing the target sample matrix and performing operations on eigenvalues and eigenvectors. Further, the present application maps the target sample matrix to a new sample matrix based on the target mapping relationship, constructs a second space coordinate system by calculating the maximum and minimum values of the matrix elements in each column of the new sample matrix, then obtains a transformation matrix according to the positional relationship between the first space coordinate system and the second space coordinate system, and finally the present application quickly transforms the target follicle to the target position on the host computer display interface according to the transformation matrix. In this way, the doctor can intuitively view the morphological structure information of the target follicle at the target position on the host computer display interface, saving the time for adjusting the position of the target follicle and greatly improving the follicle analysis efficiency.

[0091] The embodiment of the present application discloses a specific follicle repositioning method. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. Refer to Figure 6 as shown, specifically including:

[0092] Step S21: Sort the three differences.

[0093] In this embodiment, the difference between the maximum value and the minimum value of the matrix elements in each column is determined to obtain three differences, and the three differences are sorted in size.

[0094] Step S22: Determine the coordinate axis corresponding to the largest difference among the three differences as the first coordinate axis of the second spatial coordinate system, determine the coordinate axis corresponding to the smallest difference among the three differences as the second coordinate axis of the second spatial coordinate system, and determine the coordinate axis corresponding to the remaining one difference among the three differences as the third coordinate axis of the second spatial coordinate system.

[0095] In this embodiment, determine the section direction of the section where the first coordinate axis and the third coordinate axis are located as the coronal plane direction of the target follicle (i.e., the A-section direction); determine the section direction of the section where the first coordinate axis and the second coordinate axis are located as the sagittal plane direction of the target follicle (i.e., the B-section direction); determine the section direction of the section where the second coordinate axis and the third coordinate axis are located as the transverse plane direction of the target follicle (i.e., the C-section direction). Refer to Figure 7 as shown Figure 7 is a schematic diagram of an anatomical plane. It can be seen that the coronal plane is the largest section that can observe the anatomical body, followed by the sagittal plane, and the transverse plane is the smallest section that can observe the anatomical body. Similarly, in this application, the doctor can observe the section information display diagram of the target follicle through the upper computer display interface. Specifically, the coronal plane direction of the target follicle is the largest section direction that can observe the target follicle. That is, in this embodiment, the most section information of the target follicle can be observed in the coronal plane direction, followed by the sagittal plane direction and the transverse plane direction.

[0096] In one embodiment, refer to Figure 8 as shown. First, this application automatically measures the follicles in the left ovary or the right ovary, and then processes the irregularities in the identified follicles. For example, trim the places with burrs in the follicles, etc. After the processing, move the cursor to select a single target follicle, and click the right mouse button to confirm the selection. Further, reposition the target follicle based on the follicle repositioning method of this application, so as to display the target follicle at the center of the screen and each section, which is beneficial for doctors to observe.

[0097] The following elaborates on the specific implementation method of the follicle repositioning scheme:

[0098] The ultrasonic device obtains the target sample matrix of the target follicle. The volume data contained in the target follicle is n, so n m-dimensional (n×m) volume data sets X=(x 1 , x 2 , …x m ) are obtained as the target sample matrix. The number of low-dimensional space bits corresponding to it is greater than or equal to k. The following processing is performed on the volume data set:

[0099] (1) Perform centering processing on all the volume data in the volume data set to obtain the centering processing result;

[0100]

[0101] (2) Calculate the covariance matrix of the volume data;

[0102] COV = X T X;

[0103] (3) Calculate the eigenvalues and eigenvectors based on the covariance matrix;

[0104] Solve the characteristic equation |λE - X T X| = 0 to find the eigenvalues. The Jacobi method is commonly used to find the eigenvalues. Arrange the calculated eigenvalues in descending order, i.e., λ 1 ≥ λ 2 ≥... ≥ λ m ;

[0105] Respectively find the eigenvectors e i corresponding to the eigenvalues λ i (i = 1, 2,..., m), and require ||e i || = 1, that is where e i,j represents the j-th component of the vector e i ;

[0106] (4) Determine the mapping relationship based on the eigenvectors corresponding to the first several sorted eigenvalues, and map each sample x (i) of the sample set to a new sample z (i) .

[0107] Furthermore, calculate the maximum and minimum values of the matrix elements of each column of the new sample z (i) , and determine the point where half of the sum of the maximum and minimum values of the matrix elements of each column is located as the target center point, that is, the origin of the second spatial coordinate system, and construct a translation matrix accordingly. Determine the vector where the difference between the maximum and minimum values of the matrix elements of each column is located as the three coordinate axis vectors of the second spatial coordinate system, and construct a rotation matrix accordingly. The specific process is as shown in the previously disclosed content and will not be specifically described here. In this way, the present application realizes the repositioning of the target follicle to the center of the host computer display interface through the translation matrix and the rotation matrix.

[0108] In this embodiment, Figure 9 is a schematic diagram of follicle display before repositioning, Figure 10It is a schematic diagram showing the follicle after relocation. It can be seen that before relocation, the center of the target follicle does not coincide with the center of the section, and the section information of the target follicle on section B and section C cannot be observed. After relocation, the center of the target follicle coincides with the center of the section, and the section information of the target follicle on each section can be seen. Among them, the section information includes section A information, section B information, section C information, and 3D information (three dimensions).

[0109] In summary, the present application quickly calculates the translation matrix and the rotation matrix, and based on the translation matrix and the rotation matrix, quickly moves the target follicle to the upper computer display interface and the center of each section, enabling the doctor to observe the morphological structure of the follicle on each section, saving the adjustment time for the doctor to change the position of the follicle.

[0110] Correspondingly, the embodiment of the present application also discloses a follicle relocation device. Refer to Figure 11 As shown, the device includes:
