Description

Technical Field

[0001] The invention relates to an ultrasonic imaging device, and in particular to a method and a system for measuring parameters in an ultrasonic imaging image. Background Art

[0002] Female pelvic floor dysfunction is one of the chronic diseases that affect women's daily lives, including urinary incontinence, fecal incontinence, recurrent urinary tract infections and pelvic organ prolapse. At present, ultrasound examination has gradually replaced MRI as a means of evaluating pelvic floor diseases due to its repeatability, low cost, simplicity and lack of contraindications. In recent years, pelvic floor ultrasound has gradually developed and matured, and has become the preferred imaging examination method for patients with FPFD.

[0003] For ultrasound pelvic floor examination, it is often necessary to evaluate the position and mobility of the pelvic floor organs in various typical movements. The pubic symphysis is a non-synovial cartilage structure that connects the two pubic bones together. It is almost stationary when the patient is at rest and during Valsalva or anal contraction. Therefore, the pubic symphysis is an important reference structure for pelvic floor ultrasound. Regardless of the probe used, the industry generally uses a reference line related to the pubic symphysis as the basis for distance measurement.

[0004] At present, when doctors measure the position of pelvic organs or the distance of descent, they usually use a common distance ruler to draw a horizontal common distance ruler through the posterior and lower edge of the pubic symphysis. The method of drawing a horizontal common distance ruler mostly uses two points input by the user to generate a horizontal distance ruler; then the distance item is measured by using the vertical distance from the target structure (such as the bladder neck or the lowest point of the uterus) input by the user on the ultrasound image to the horizontal line, which is completely based on the horizontal and vertical relationship of the visual line. Therefore, the operation is not convenient, and there is no reference basis for the measurement accuracy. Based on the new requirements for parameter measurement put forward by doctors in actual operation, a more convenient and easy-to-operate measurement method needs to be provided. Summary of the invention

[0055] The present invention is further described in detail below by specific embodiments in combination with the accompanying drawings. Among them, similar elements in different embodiments use associated similar element numbers. In the following embodiments, many detailed descriptions are intended to make the present application better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core part of the present application being overwhelmed by too much description. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the field. In addition, the characteristics, operations or features described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the accompanying drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that they are necessary sequences, unless otherwise specified that a certain sequence must be followed. The serial numbers themselves, such as "first", "second", etc., for the components herein are only used to distinguish the objects described and do not have any sequence or technical meaning.

[0056] Figure 1The ultrasonic imaging system shown includes: a probe 101, a transmitting circuit 101, a transmitting / receiving selection switch 102, a receiving circuit 104, a beamforming module 105, a signal processing module 116, and an image processing module 126. During the ultrasonic imaging process, the transmitting circuit 101 sends a delayed focused transmitting pulse with a certain amplitude and polarity to the probe 101 through the transmitting / receiving selection switch 102. The probe 101 is stimulated by the transmitting pulse to transmit ultrasonic waves to the target tissue (for example, organs, tissues, blood vessels, etc. in the human body or animal body), and receives the ultrasonic echo with information of the target tissue reflected from the target area after a certain delay, and reconverts the ultrasonic echo into an electrical signal. The receiving circuit 104 receives the electrical signal converted and generated by the probe 101, obtains the ultrasonic echo signal, and sends the ultrasonic echo signal to the beamforming module 105. The beamforming module 105 performs focusing delay, weighting and channel summing on the ultrasonic echo signal, and then sends the ultrasonic echo signal to the signal processing module 116 for related signal processing. The ultrasonic echo signal processed by the signal processing module 116 is sent to the image processing module 126. The image processing module 126 processes the signal differently according to the different imaging modes required by the user, obtains ultrasonic image data of different modes, and then forms ultrasonic images of different modes through logarithmic compression, dynamic range adjustment, digital scan conversion and other processing, such as B image, C image, D image, Doppler blood flow image, elastic image containing tissue elastic properties, etc., or other types of two-dimensional ultrasonic images or three-dimensional ultrasonic images. The elastic image can be obtained by transmitting ultrasonic waves to detect the shear wave characteristics inside the target tissue, or it can also be obtained by transmitting ultrasonic waves to detect the deformation of the target tissue caused by external force, wherein the shear wave can be obtained by external force vibration, or it can be excited by transmitting ultrasonic waves to the target tissue.

[0057] In some embodiments of the present invention, the signal processing module 116 and the image processing module 126 may be integrated on a mainboard 106, or one or more (including the above in this document) of the modules may be integrated on a processor / controller chip.

[0058] Secondly, the ultrasound imaging system further includes an external input / output port 108, which is disposed on the mainboard 106. The ultrasound imaging system can be connected to a human-computer interaction device through the external input / output port 108, and is used to receive a command signal input through the human-computer interaction device through the external input / output port 108, and the command signal includes a control command for ultrasonic emission and reception timing, an operation input command for editing and marking ultrasound images, an output command for reminding the user, or other command types. Usually, the operation command obtained when the user performs operation inputs such as editing, marking, and measuring ultrasound images is used for measurement of target tissues. The human-computer interaction device can include a keyboard, a mouse, a scroll wheel, a trackball, and a mobile input device (a mobile device with a touch screen, a mobile phone, etc.), a multi-function knob, etc., one or more of which are combined, so the corresponding external input / output port 108 can be a wireless communication module, a wired communication module, or a combination of the two. The external input / output port 108 can also be implemented based on USB, bus protocols such as CAN, and / or wired network protocols, etc.

[0059] In addition, the ultrasonic imaging system may further include a display 107, which is used to display the ultrasonic image data from the image processing module. The display 107 may be a touch screen display. Of course, the ultrasonic imaging system may also be connected to another display through an external input and output port to realize a dual-screen display system. In addition, the display in this embodiment may include one display or multiple displays, and the number of displays is not limited in this embodiment. The displayed ultrasonic image data (ultrasound image) may be displayed on one display or on multiple displays at the same time. Of course, it may also be that parts of the ultrasonic image are synchronously displayed on multiple displays respectively, which is not limited in this embodiment. In addition, while displaying the ultrasonic image, the display also provides the user with a graphical interface for human-computer interaction, and one or more controlled objects are set on the graphical interface, providing the user with a human-computer interaction device to input operation instructions to control these controlled objects, thereby performing corresponding control operations. For example, an icon is displayed on the graphical interface, and the icon can be operated using the human-computer interaction device to perform a specific function. Tracking the output of the human-computer interaction device can obtain the interface operation position corresponding to the graphical interface, and perform related specific functional operations based on the interface operation position, such as positioning the display update of the controlled object, etc. The interface operation position mentioned in this article refers to the position on the display interface corresponding to when the user uses the human-computer interaction device to operate the interface object. The "position" mentioned in this article includes orientation information, coordinate information, and / or angle information, etc. For example, the position of a line can be represented by the coordinate information of all pixels on the line, or by the angle information based on the reference line. Therefore, the position change can be a change in coordinate information or a change in angle information. The interface objects include the cursor, the first straight line, the second straight line, the measurement mark and other interface controlled objects. There are many ways to locate the interface operation position based on the human-computer interaction device. Different algorithms are used for position tracking according to different human-computer interaction devices. For example, the position of the interface operation position is located by tracking the moving direction and speed of the operation input using a trackball.

[0060] like Figure 2 As shown, a flow chart of a method for measuring parameters in an ultrasound image is provided. Figure 1 The execution process of the parameter measurement method in this embodiment is described in detail.

[0061] In step S210, the image processing module 126 in the ultrasound imaging system acquires an ultrasound image, which contains the target tissue.

[0062] like Figure 1 As shown, the ultrasound image can be obtained by using the ultrasound probe 101 to receive the ultrasound signal from the target tissue. The ultrasound signal in this embodiment is not limited to the ultrasound signal in the above reference. Figure 1The ultrasonic echo signal to be interpreted may also be an ultrasonic signal generated in the target tissue by a method such as photoacoustic imaging. In addition, the target tissue here includes but is not limited to pelvic floor tissue, which includes one or more anatomical tissue structures in the female pelvic cavity, such as the uterus, labia, perineum, pelvis, phalangeal joint, etc. The ultrasonic image containing the pelvic floor tissue includes but is not limited to anterior pelvic ultrasound image and posterior pelvic ultrasound image, and may also include middle pelvic ultrasound image. The commonly used measurement items of pelvic floor ultrasound are divided into anterior pelvic cavity and posterior pelvic cavity, wherein the parameter measurement based on the anterior pelvic ultrasound image and the middle pelvic ultrasound image is mainly completed on the human body mid-sagittal plane image obtained by using a translabial or transperineal probe. The parameter measurement based on the posterior pelvic ultrasound image can be acquired by using an endoanal probe, or more conveniently by using a transperineal probe or a transvaginal probe to acquire a static three-dimensional image or a four-dimensional image, and selecting an appropriate section on the axial plane for relevant measurement. Based on the parameter measurement of the posterior pelvic ultrasound image, the description of this embodiment is based on the second case mentioned above, that is, the posterior pelvic ultrasound image obtained by image acquisition through the perineum or transvaginal probe.

[0063] In step S220 , the image processing module 126 in the ultrasound imaging system outputs the ultrasound image to a display for displaying the ultrasound image.

[0064] See the description of the display 107 in the foregoing text. The manner of displaying the ultrasound image in this embodiment is not limited. For example, it can be displayed on multiple displays simultaneously, or only on one display, or it can be displayed on multiple displays in parts synchronously, thereby expanding the viewing angle of the ultrasound image. Further, in one of the embodiments, the image processing module 126 can transmit the ultrasound image to the display in a wireless or wired manner. The display can be a touch screen display on a mobile device. Further, in one of the embodiments, the ultrasound image is displayed on a first layer, which is a software interface layer other than the non-image data for displaying annotations, annotations, texts, cursors, measuring scales, etc. Correspondingly, the software interface layer for displaying non-image data such as annotations, annotations, texts, cursors, measuring scales, etc. is called a second layer, and the second layer is set to a transparent attribute in the area overlapping with the first layer, so that the ultrasound image can be not blocked, and the visibility and interface friendliness are enhanced. Further, the entire second layer is set to a transparent attribute.

[0065] Furthermore, in one embodiment, if Figure 3As shown, the area for displaying ultrasound images on the display interface 300 can be independently set as an image display window 301, and the video image or single-frame image can be displayed in the image display window 301, and the area outside the image display window can also be used to display non-image data such as annotations, labels, and texts, wherein the ultrasound image of the target tissue after image processing is 302. Of course, there can be one or more image display windows on the same display interface to achieve a multi-window display effect on the same screen, which is used to compare and browse images, such as Figure 4 As shown, on the display interface 400, two image display windows 401 and 402 are displayed on dual screens, wherein the ultrasound images of the target tissue after image processing are 411 and 412 respectively. In some embodiments, the image display window is set by the image pixel position range. For example, if the current display interface is 1478*2897, then 200*400 at the corresponding position is set as an image display window, and an image display window of the same size is provided in parallel at the same position, one of which displays a static image frame and the other displays an active video image. The video image includes multiple frames of ultrasound images.

[0066] In step S230, the image processing module 126 superimposes and displays a first straight line and a second straight line perpendicular to each other on the ultrasound image using the display 107, and the first straight line and the second straight line intersect to generate an intersection point. For example, by default, the first straight line is placed horizontally and the second straight line is placed vertically.

[0067] For example, in Figure 3 In the image display window 301, a first straight line 303 is superimposed on the ultrasound image 302. The first straight line 303 is absolutely horizontally placed. A second straight line 304 is superimposed at the same time. The second straight line 304 is arranged to intersect the first straight line vertically. The second straight line 304 and the first straight line 303 intersect to form an intersection 305. In addition, the first straight line 303 and the second straight line 304 can be displayed separately, so that the first straight line 303 and the second straight line 304 cannot be distinguished after the first straight line is adjusted. Figure 3 In the embodiment, the first straight line and the second straight line are displayed by using different line types. Of course, they can also be distinguished by color. The line type here can include a solid line, a dotted line, a dashed line, etc. In one embodiment, Figure 3 In the figure, the first straight line 303 and the second straight line 304 cross the image display window 301 of the ultrasound image. The result of the crossing is that the first straight line 303 and the second straight line 304 cross the boundary 311 of the image display window 301 by a preset distance. The oversized mark can provide users with a better interactive experience and facilitate users to locate the position on the ultrasound image more accurately.

[0068] In order to prominently display the effect of the first straight line and the second straight line as measurement scales and improve the interactive experience with the user operation, the first straight line and the second straight line are floated on the ultrasound image display and do not block the ultrasound image. In some examples, such as Figure 5 As shown, the first straight line 512 and the second straight line 513 are set on the second layer 502, and the ultrasound image 511 is displayed on the first layer 501 below the second layer 502, and the second layer 502 is a transparent layer. When the first straight line 512 is adjusted, the properties of the first straight line on the second layer 502 will change. The properties mentioned here include parameters such as size, line type, color, visibility, etc., and the display results of the first straight line or the second straight line can be changed by adjusting these parameter properties, including display position and display form. After the first layer and the second layer are superimposed, a Figure 5 The rightmost display result is that the first straight line 512 and the second straight line 513 are superimposed on the ultrasound image 511. Further, the ultrasound image 511 is displayed in the image display window 503. Of course, the area range where the first straight line 512 and the second straight line 513 can be displayed and operated on the second level 502 can be greater than or equal to the area range of the single image display window 503 on the first level 501. The area range where the first straight line 512 and the second straight line 513 can be displayed and operated on the second level 502 may include: a rectangular or square area with the length of the first straight line 512 and the second straight line 513 as the length and width, or a circular area surrounded by the longest line of the first straight line 512 and the second straight line 513 as the diameter.

[0069] like Figure 4 As shown, in multi-screen display, for example Figure 4 In the embodiment, there are two image display windows 401 and 402, wherein the ultrasound images are 411 and 412 respectively, and the first straight line and the second straight line superimposed on the ultrasound images 411 and 412 are respectively the first straight line 431 and the second straight line 421 located in the image display window 401, and the first straight line 432 and the second straight line 442 located in the image display window 402. In order to avoid confusion between the measurements of the images in the multi-screen display mode, in one embodiment, the first straight line and / or the second straight line can be adjusted only after the image display window is activated, so as to perform the measurement on the ultrasound image. For example, if the first straight line 431 and the second straight line 421 located in the image display window 401 are to be adjusted, the image display window 401 is activated, and if the first straight line 432 and the second straight line 442 located in the image display window 402 are to be adjusted, the image display window 402 is activated. In the activated image display window, the first straight line and / or the second straight line can be adjusted.

[0070] During the process of adjusting the first straight line, the current image display window is activated, and the activation can be implemented in the following manner.

[0071] First, the image processing module determines the interface operation position corresponding to the first operation or the second operation input by the human-computer interaction device; secondly, the image display window is determined according to the interface operation position associated with the first operation or the second operation as the current image display window; then, the current image display window is activated. In this embodiment, the current image processing window can be identified by tracking the interface operation position corresponding to the first operation or the second operation input by the human-computer interaction device, so that the image display window is automatically activated, without the need to perform independent activation operations through human-computer interaction devices such as buttons, thereby improving the user experience and making the measurement operation more friendly.

[0072] In step S240, the image processing module 126 receives a first instruction generated when a first operation is inputted using a human-computer interaction device. In step S250, according to the first instruction, the display of the first straight line and / or the second straight line is updated, so that the display of the first straight line and / or the second straight line is linked to the input of the first operation. The purpose of updating the display of the first straight line and / or the second straight line is that when the input of the first operation changes, the display of the first straight line and / or the second straight line also changes accordingly, and during the updating process of the first straight line and / or the second straight line, the second straight line always intersects the first straight line vertically. For example, when the first operation is continuously inputted using a trackball to generate a first instruction, the display of the first straight line and / or the second straight line will also change accordingly.

[0073] In this embodiment, the intersection of the first straight line and the second straight line or the first straight line can be used as a controlled cursor, without displaying a cursor icon on the interface as a controlled interface object other than the first straight line and the second straight line. In this way, the first straight line and the second straight line can be used as a ruler or a cursor. When the human-computer interaction device is used for operation input, the operation can be performed on the intersection of the first straight line and the second straight line by default, which can simplify the interface display and facilitate user operation.

[0074] In the process from step S240 to step S250, the first instruction generated when the first operation is inputted by the human-computer interaction device can realize the overall movement of the first straight line and the second straight line, or the movement of the first straight line or the second straight line separately, or the rotation operation of the first straight line, etc. The following is a specific example.

[0075] For example, in one embodiment, the overall movement of the first straight line and the second straight line is achieved in the process from step S240 to step S250 in the following manner:

[0076] First, the image processing module receives a third instruction generated when a third operation is inputted using the human-computer interaction device. The third operation in this embodiment can be implemented by operating a trackball. The operation of the trackball can be inputted continuously.

[0077] Secondly, the image processing module monitors the second interface operation position corresponding to the third operation, and tracks the change of the second interface operation position, where the second interface operation position is any position in the image display window;

[0078] Then, the intersection position of the first straight line and the second straight line is assigned as the tracking result of the second interface operation position, and the first straight line and the second straight line are redrawn based on the reassigned intersection point, so as to achieve the input of the human-computer interaction device so that the first straight line and the second straight line as a whole produce a linkage effect with the input of the operation.

[0079] like Figure 6 As described, on the display interface 600, there is an image display window 601, an ultrasound image 608 is displayed in the image display window 601, and a first straight line 602 is displayed at a position 614 and a second straight line 604 is displayed at a position 611, and an intersection 603 of the first straight line 602 and the second straight line 604 is at a position 612. The intersection 603 is used as a controlled object of human-computer interaction. The image processing module receives a third instruction generated when a third operation is input using a human-computer interaction device such as a trackball, the third operation is used to control the intersection 603, monitor the second interface operation position corresponding to the third operation, and track the change of the second interface operation position, Figure 6 The second interface operation position is tracked to change to 612, the position of the intersection 603 of the first straight line 602 and the second straight line 604 is changed to the second interface operation position 612, and based on the changed intersection position, the first straight line 602 and the first straight line 604 are redrawn, thereby realizing the overall movement of the first straight line and the second straight line, and the first straight line and the second straight line can be moved as a whole to any position in the image display window with the input of the first three operations. In this embodiment, the overall movement of the first straight line and the second straight line can be moved to the target position in one step, or it can be moved to the target position in two times, for example, first the intersection is moved along the second straight line to adjust the position of the second straight line on the first straight line, and then the intersection is moved along the first straight line to adjust the position of the first straight line on the second straight line, so that the intersection is moved to the target position, and this variation also falls within the protection scope of this embodiment. It can be seen that the above-mentioned third operation includes a single operation input, and can also include continuous input of multiple operations. The second interface operation position can include one interface operation position, and can also include multiple interface operation positions, and the multiple interface operation positions can be continuous or discontinuous.

[0080] For another example, in one embodiment, in the process from step S240 to step S250, the translation of the first straight line is achieved by:

[0081] First, the image processing module receives a fourth instruction generated when a fourth operation is inputted by using the human-computer interaction device. The fourth operation in this embodiment can be implemented by operating a trackball.

[0082] Secondly, the image processing module monitors the third interface operation position corresponding to the fourth operation, and tracks the change of the third interface operation position in the vertical direction, wherein the third interface operation position remains unchanged in the horizontal direction;

[0083] Again, the position of the intersection of the first straight line and the second straight line is assigned as the tracking result of the third interface operation position, and the first straight line is redrawn based on the assigned intersection.

[0084] like Figure 8 As shown, in Figure A, a first straight line 81 is displayed at position 83 on the display interface, and a second straight line 82 is displayed to intersect the first straight line 81 vertically, and the intersection point is at the bladder neck. In Figure B, the image processing module receives a fourth instruction generated when a fourth operation is input using a human-machine interaction device such as a trackball, monitors the third interface operation position corresponding to the fourth operation, tracks the change of the third interface operation position in the vertical direction, and the positioning of the third interface operation position in the horizontal direction remains unchanged, that is, the intersection point in Figure B changes to position 85 along the second straight line, then the position of the intersection point of the first straight line and the second straight line is assigned as the tracking result of the third interface operation position, and based on the assigned intersection point, the first straight line is redrawn at position 85 by drawing 81, and during this movement, the second straight line 82 is fixed. In this embodiment, the intersection point of the first straight line and the second straight line is used as the controlled object, and the fourth operation is used to control the intersection point. It can be seen that through this embodiment, a measurement method in which the first straight line moves stepwise along the second straight line can be presented, the measurement accuracy can be improved, the effect of the second straight line as a measurement reference can be achieved, the user operation is convenient, and the operation experience is improved. It shows the user a clearer position change process, which is convenient for doctors to determine the accuracy when performing measurement operations and reduce input errors. Figure 8 The process from A, B, to C in sequence. It can be seen that the fourth operation includes a single operation input, and may also include continuous input of multiple operations. The third interface operation position may include one interface operation position, or may include multiple interface operation positions, and the multiple interface operation positions may be continuous or discontinuous.

[0085] Similarly, for example, in one embodiment, in the process from step S240 to step S250, the translation of the second straight line is achieved in the following manner:

[0086] First, the image processing module receives the fifth instruction generated when the fifth operation is inputted using the human-computer interaction device. The fifth operation in this embodiment can be implemented by operating the trackball; secondly, the image processing module monitors the fourth interface operation position corresponding to the fifth operation, and tracks the change of the fourth interface operation position in the horizontal direction, wherein the fourth interface operation position remains unchanged in the vertical direction; thirdly, the position of the intersection of the first straight line and the second straight line is assigned as the tracking result of the fourth interface operation position, and the second straight line is redrawn based on the assigned intersection. How to translate the second straight line alone is not specifically described here, and please refer to the relevant Figure 8 In the related description of moving the first straight line, the fifth operation and the fourth operation can be the same, and the fifth instruction can be the same as the fourth instruction. It can be seen that the fifth operation can also include a single operation input, or continuous input of multiple operations. The fourth interface operation position can also include one interface operation position, or multiple interface operation positions, and the multiple interface operation positions can be continuous or discontinuous.

[0087] The method of this embodiment can realize the translation of the second straight line. Of course, further combining the above-mentioned translation of the first straight line and the translation of the second straight line can realize the overall translation of the first straight line and the second straight line, as shown below.

[0088] In the process from step S240 to step S250, the overall movement of the first straight line and the second straight line is achieved by:

[0089] First, the image processing module receives a fourth instruction generated when a fourth operation is inputted by using the human-computer interaction device. The fourth operation in this embodiment can be implemented by operating a trackball.

[0090] Secondly, the image processing module monitors the third interface operation position corresponding to the fourth operation, and tracks the change of the third interface operation position in the vertical direction, wherein the third interface operation position remains unchanged in the horizontal direction;

[0091] Thirdly, the position of the intersection of the first straight line and the second straight line is assigned as the tracking result of the third interface operation position, and the first straight line is redrawn based on the assigned intersection;

[0092] Next, the image processing module receives a fifth instruction generated when a fifth operation is input again using the human-computer interaction device. The fifth operation in this embodiment can be implemented by operating a trackball.

[0093] Secondly, the image processing module monitors the fourth interface operation position corresponding to the fifth operation, and tracks the change of the fourth interface operation position in the horizontal direction, wherein the fourth interface operation position remains unchanged in the vertical direction;

[0094] Again, the position of the intersection of the first straight line and the second straight line is assigned as the tracking result of the fourth interface operation position, and the second straight line is redrawn based on the assigned intersection.

[0095] The fourth instruction and the fifth instruction outputted by the fourth operation and the fifth operation inputted twice in the above process may contain different instruction information. For example, the input of the two operations can be distinguished by operating the trackball in different directions.

[0096] For example, in one embodiment, the rotation of the first straight line and the second straight line is achieved in the process from step S240 to step S250 in the following manner:

[0097] First, the image processing module receives a sixth instruction generated when a sixth operation is inputted using the human-computer interaction device;

[0098] Secondly, the image processing module extracts the rotation instruction information according to the sixth instruction;

[0099] Then, the image processing module rotates the first straight line or the second straight line with the intersection as the center according to the extracted rotation instruction information.

[0100] like Figure 7 As shown, on the display interface 700, there is an image display window 701, an ultrasound image 708 is displayed in the image display window 701, and a first straight line 702 is displayed at position 71 and a second straight line 704 is displayed at position 73, and the intersection of the first straight line 702 and the second straight line 704 is 703. The first straight line 702 is used as the controlled object of human-computer interaction. The image processing module receives a sixth instruction generated when a sixth operation is input using a human-computer interaction device such as a knob, and the sixth operation is used to control the intersection 703. According to the sixth instruction, rotation indication information is extracted, and the rotation indication information includes angle information, which is used to adjust the angle of the first straight line 702 relative to the initial position 71, or the angle of the second straight line 704 relative to the initial position 73. The image processing module rotates the first straight line 702 or the second straight line 704 with the intersection of the first straight line and the second straight line as the center according to the extracted rotation indication information, thereby realizing the rotation adjustment of the first straight line and / or the second straight line. Furthermore, when the first straight line 702 rotates, the second straight line may also rotate synchronously with the rotation of the first straight line, for example, rotating from position 73 to position 74, thereby ensuring that the first straight line always intersects the second straight line perpendicularly.

[0101] In order to ensure that the first straight line and the second straight line provided to the user provide an absolute measurement reference and improve accuracy, in one embodiment, the first straight line and the second straight line are always perpendicular to each other. For example, in the above steps S240 and S250, the image processing module 126 receives the first instruction generated when the first operation is input using the human-computer interaction device, and in the process of updating the display of the first straight line according to the first instruction, one of the following methods is used to make the first straight line and the second straight line always perpendicular to each other:

[0102] like Figure 7 As shown, in the process of adjusting the first straight line 702, the second straight line 704 changes along with the position change of the first straight line 702, and always intersects the first straight line 702 perpendicularly. Figure 7 When the first straight line 702 rotates from position 71 to 72, the second straight line 704 also rotates synchronously from position 73 to position 74; and,

[0103] like Figure 8 As shown, when the first straight line 702 is adjusted to rotate from position 71 to position 72, the second straight line 704 remains at position 73. When the first straight line 702 is adjusted to the target position or the desired position, the position of the second straight line is automatically changed to intersect the first straight line perpendicularly.

[0104] The target position mentioned in this article is the position to which the interface object is expected to be adjusted when the user performs an adjustment input operation on the interface object through the human-computer interaction device, such as the lower edge of the pubic symphysis, the central axis of the pubic symphysis, and other relevant anatomical structures of the target tissue on the ultrasound image. When the user performs an input operation on the interface object (including the controlled object) through the human-computer interaction device, a corresponding interface operation position will be generated on the display interface. The interface operation position can be a pixel coordinate position or a neighborhood position area composed of multiple pixels.

[0105] Through the above-mentioned embodiments, the measurement effect of the first straight line and / or the second straight line linked with the user input operation can be achieved, thereby improving the operation experience and facilitating the user to accurately locate the image position for measurement operation.

[0106] In the above-mentioned embodiments, the rotation of the first straight line, the translation of the first straight line, and the overall movement of the first straight line and the second straight line are respectively realized. The above-mentioned third operation, fourth operation, fifth operation, and sixth operation can all be the continuous input of instructions by the user based on the human-computer interaction device. Therefore, the above-mentioned third instruction, fourth instruction, fifth instruction, and sixth instruction can all be the continuous input of the user based on the human-computer interaction device. The continuous input mentioned in this article means that the user continuously inputs instructions using the human-computer interaction device for a period of time. For example, it can include the user continuously inputting movement operations using a trackball, and the user continuously inputting position change information using a keyboard, so that the interface objects displayed on the interface can present a constantly moving display effect on the screen through continuous input, thereby improving the interactive experience. Therefore, in step S240 and step S250, the image processing module receives the continuous input of the first instruction to update the display of the first straight line and / or the second straight line, so that the display of the first straight line and / or the second straight line is linked with the continuous input.

[0107] See also Figure 2 In this embodiment, the parameter measurement method based on ultrasound images may also include steps S260, S270 and S280, which are used to confirm the position of the first straight line after the linkage operation is performed, and obtain measurement instructions for realizing the calculation of ultrasound image measurement items.

[0108] In step S260, the image processing module receives the second instruction generated when the second operation is inputted by the human-computer interaction device. In step S270, the image processing module extracts the corresponding first interface operation position according to the second instruction. In step S280, the image processing module records the first interface operation position associated with the second instruction. Figure 8 and Fig. 9 Give an example.

[0109] like Figure 8 as well as Fig. 9 As shown, an embodiment of inputting an operation instruction using a first straight line and a second straight line is provided. The ellipse in the figure represents the pubic symphysis, and the black dot represents the bladder neck. The image processing module 126 receives a first instruction generated when a first operation is input using a human-computer interaction device, updates the first straight line 81 according to the first instruction, and records the position determined by measurement according to a second instruction generated when a second operation is input using the human-computer interaction device.

[0110] Figure 8In Figure A, the intersection of the first straight line and the second straight line is at the position of the bladder neck. When the initial display positions of the first straight line and the second straight line are not at the desired position or the target position (such as when the intersection is not at the bladder neck position), the intersection of the first straight line 81 and the second straight line can be updated to the desired position or the target position according to the first instruction generated when the first operation is input using the human-computer interaction device. For details, please refer to the relevant description above.

[0111] In the process of changing from Figure A to Figure B, when the intersection of the first straight line and the second straight line moves to the desired position or the target position, the user needs to mark the position and record it for measurement and calculation of the ultrasound image. Therefore, the user will use the human-computer interaction device to input the second operation to confirm the position. The second operation here can provide the input of the instruction through hardware such as buttons, and the commonly used one is the set setting key on the ultrasound device keyboard. The image processing module receives the second instruction generated when the second operation is input using the human-computer interaction device, and extracts the corresponding first interface operation position, that is, position 83, according to the second instruction, which is used as data for measuring the ultrasound device, so as to facilitate the generation of subsequent measurement instructions.

[0112] The intersection of the first straight line and the second straight line moves to position 85, and the first straight line is translated downward. In order to facilitate the user to understand the position that he has marked on the interface, when the first straight line or the intersection of the first straight line and the second straight line is moved, a position mark 87 is marked at the initial position (i.e., the bladder neck position) of the intersection of the first straight line and the second straight line. Continue the measurement operation, when according to the received four instructions, the third interface operation position corresponding to the fourth operation related to the fourth instruction is monitored, and the change of the third interface operation position is tracked, for example Figure 8 The change of the third interface operation position in the vertical direction is tracked, and the positioning of the third interface operation position in the horizontal direction remains unchanged, that is, the intersection in Figure B changes to position 84 along the second straight line. When the user determines that the first straight line has reached position 84 and has passed another target position (such as the lower edge of the pubic symphysis), the second operation is input using the human-computer interaction device to confirm the position. The image processing module receives the second instruction generated when the second operation is input using the human-computer interaction device, and extracts the corresponding first interface operation position, that is, position 84, according to the second instruction. The image processing module records the first interface operation position 84 associated with the second instruction, indicating that the position of the lower edge of the pubic symphysis is determined using the first straight line. After completing the measurement operation, Figure 8When the second instruction input by the user is received, it indicates that the user has confirmed the position of at least one reference line or a target position to be measured. At this time, the first straight line 81 is shortened, hidden, or deleted. When the first straight line 81 is hidden or deleted, a position mark 88 is marked at the corresponding position to form a D image. In one embodiment, there is only one first straight line in the same image display window. The corresponding measurement instruction can be obtained based on the position marks 87 and 88.

[0113] Fig. 9 The embodiment given mainly focuses on the rotation operation of the first straight line 91. Both the translation operation and the rotation operation belong to the moving operation. Therefore, the first instruction to update the display of the first straight line includes: the sixth instruction for rotating the first straight line, and the moving process of the first straight line includes: the image processing module receives the sixth instruction generated when the sixth operation is input by the human-computer interaction device, and extracts the rotation instruction information according to the sixth instruction, such as the angle information of rotating from the position 93 to the target position 94; the first straight line 91 is updated and displayed on the interface operation position 94 linked with the sixth instruction, so that the first straight line 91 is rotated from the current first position 93 to the target position 94, see Fig. 9 During the rotation, the first straight line 91 is rotated according to the angle information contained in the extracted rotation instruction information with the intersection of the first straight line and the second straight line as the center, so that it is aligned with the reference line ( Fig. 9Of course, the second straight line 92 can also be rotated in the above manner. When the rotation reaches the target position 94, the second straight line 92 is automatically adjusted to be perpendicular to the first straight line 91, or when the rotation does not reach the target position, the second straight line 92 automatically adjusts the perpendicular relationship with the position change of the first straight line 91, so as to ensure that the first straight line 91 and the second straight line 92 are always perpendicular when the rotation operation is performed, so that the second straight line 92 is also rotated from position 95, or rotates synchronously with the first straight line to position 96. In the process of rotating the first straight line 91 according to the fifth instruction, the first straight line 91 is rotated with the intersection of the first straight line 91 and the second straight line 92 as the center. If the position of the bladder neck is to be marked, when the first straight line is overlapped with the red reference line 910 and the position of the reference line is determined, the second operation is input by the human-computer interaction device to confirm the position (for example, it can be confirmed by key input), and the image processing module receives the second instruction generated when the second operation is input by the human-computer interaction device, and extracts the corresponding first interface operation position, that is, position 94, according to the second instruction. The image processing module records the first interface operation position 94 associated with the second instruction, indicating that the user has confirmed the position of at least one reference line or a target position to be measured, for example, the position of the central axis of the pubic symphysis is determined by using the first straight line. When the first straight line is translated to continue marking the position of the bladder neck, after the first straight line is moved, in order to enable the user to view the marked position on the image, a position mark 97 (in Figure C) can be marked on the second straight line to record this position as the determined position of the central axis of the pubic symphysis. When continuing to mark the position of the bladder neck, a fourth instruction generated when a fourth operation is inputted using the human-computer interaction device is received, and the third interface operation position corresponding to the fourth operation is monitored. The third interface operation position remains unchanged in the horizontal direction. It can be seen from Figure C that the intersection of the first straight line and the second straight line always moves on the second straight line, and the change of the third interface operation position in the vertical direction is tracked; the position of the intersection of the first straight line and the second straight line is assigned as the tracking result of the third interface operation position, and the first straight line 91 is redrawn based on the assigned intersection, so as to present a translation display effect of the first straight line along the second straight line, until the first straight line passes through the bladder neck at position 95, and the image processing module receives a second instruction generated when a second operation is inputted using the human-computer interaction device, such as receiving a confirmation instruction performed by the user by clicking a button, and then the image processing module extracts the corresponding first interface operation position according to the second instruction, records the first interface operation position associated with the second instruction, and indicates that the user has confirmed the position of at least one reference line or a target position to be measured, such as determining the position of the bladder neck using the first straight line. Then, the marked position can be recorded by marking a position mark 98 on the second straight line, which is used to obtain a measurement instruction and perform measurement calculations on the ultrasound image.The appearance of the position mark may be based on one user operation input or two user operation inputs, and this embodiment does not limit this. That is, the second instruction generated when the second operation is input using the human-computer interaction device may be input as a single instruction or as multiple instructions. For example, the position mark may be marked on the ultrasound image by one operation input through a key, or by two consecutive operation inputs. The distance relationship between the bladder neck position and the central axis of the pubic symphysis may be obtained based on the position mark 97 and the position mark 98, and used to calculate the corresponding measurement items.

[0114] like Figure 8 and Fig. 9 As shown, in one embodiment, after recording the interface operation position associated with the second instruction, the image processing module further includes:

[0115] Position marks (87, 88, 97, 98) are drawn, and the position marks (87, 88, 97, 98) are located on the second straight line (82, 92). The position mark can be a line segment, or a cross mark or the like that can be used as an icon for position identification.

[0116] Furthermore, in one embodiment, the image processing module will delete the redundant second straight line to avoid the mark covering the ultrasound image, and display the portion (89, 99) of the second straight line, which is located between the two position marks and / or between the position mark and the first straight line.

[0117] Fig. 9 The red dotted line 910 in the middle provides a position prompt mark of the central axis of the pubic symphysis, which is obtained through automatic image segmentation and automatically provided by the system. It can provide a certain reference when the user performs coordinate positioning or reference line positioning in image measurement, and has a more practical clinical value. Therefore, in some variant embodiments of this embodiment, position prompt marks can also be displayed on the ultrasound image. These position prompt marks can be obtained through automatic image segmentation of the system, or can be obtained by the system plus manual methods during the automatic scanning process.

[0118] In each of the embodiments provided above, the operation of the first straight line and the second straight line can realize point-to-point distance measurement, or point-to-line measurement, and the combination of the two. It is very simple and easy to operate, and: an absolutely horizontal reference line can be obtained to improve the measurement accuracy. After the measurement is completed, the two ends of the ruler are short lines, such as the position of the position mark and the second straight line are partially displayed, which can reduce image occlusion; the distance end reference line can be moved on both sides of the distance starting point short line, so the distance can be measured on both sides, which meets the pelvic floor application. The two vertical cursor lines (the first straight line and the second straight line) have different colors or line types. No matter how they are rotated, the user knows in which direction to rotate the minimum angle to quickly make the measurement cursor coincide with the reference line.

[0119] Fig. 9 In the illustrated embodiment, when the first straight line 92 moves to the pubic symphysis central axis position 94, the properties of the first straight line 92 can be changed according to the input of the second instruction when recording the interface operation position associated with the second instruction, and the first straight line is located at the interface operation position associated with the second instruction. For example, the line type of the first straight line 92 is changed to prompt the user that the position of the reference line has been confirmed. Changing the properties of the first straight line includes at least one of the following methods: setting the operation property of the first straight line to be immovable, and setting the line type of the first straight line to a preset line type. For details, see Fig.10 The measurement process is shown.

[0120] Above Figure 8 and Fig. 9 In the movement process of the first straight line shown, in order to facilitate the measurement operation, after at least one marking is performed to obtain the position mark (87, 88, 97, 98), the first straight line can not only move on the side where the position mark is located on the second straight line, but also move on both sides of the position mark on the second straight line. That is to say, during the translation of the first straight line, the position of the intersection of the first straight line and the second straight line can be moved arbitrarily on the first straight line or the second straight line.

[0121] Fig.10 A process of measuring by using various operations and display modes of the first straight line and the second straight line is provided, and the specific process is as follows.

[0122] The measurement operation mode is entered by key input or other mode selection operations, and then the horizontally placed first straight line 102 and the vertically placed second straight line 101 are superimposed and displayed on the ultrasound image, as shown in FIG. Fig.10 (1) is shown. The first straight line and the second straight line may be distinguished by different colors and / or line types. An ultrasound image 120 is displayed in the image display window 100.

[0123] like Fig.10(2) As shown in FIG. 1 , in combination with the above-mentioned movement operation of the first straight line and / or the second straight line according to the received first instruction, the intersection of the first straight line and the second straight line is located at the target position, such as the lower edge of the pubic symphysis. For specific operations, please refer to the above-mentioned related Figure 6 , Figure 7 , Figure 8 and Fig. 9 Related instructions.

[0124] like Fig.10 As shown in (3), assuming that Fig.10 In (2), when the intersection of the first straight line 102 and the second straight line 101 moves to the first target position (e.g., the lower edge of the pubic symphysis), and the first straight line is also located at the second target position (e.g., the central axis of the pubic symphysis), the first interface operation position associated with the second instruction, i.e., the second target, can be recorded as a reference for the production measurement instruction according to the received second instruction. Fig.10 In (3), after receiving the second instruction, the image processing module records the first interface operation position where the first straight line is currently located, such as the position of the central axis of the pubic symphysis. The first straight line at this position is used as or configured as a reference line, and the properties of the first straight line are changed to indicate that the first straight line 102 is marked as a reference line. Changing the properties of the first straight line at least includes: configuring the first straight line to be immovable, and setting the properties of the first straight line to one of the preset properties. The property setting may be a change in color, line type, etc., such as changing the line type of the first straight line 102 from a dotted line to a dash-dotted line. In addition, in one of the embodiments, a movable active cursor 130 is drawn at the intersection of the first straight line 102 and the second straight line 101. The movable active cursor can be moved to any position on both sides of the first straight line 102. In order to facilitate the operation of the movable cursor 130, the image processing module makes the cursor smaller, or adjusts the second straight line to be hidden, or deletes the second straight line, or changes the second straight line to a variable line whose length can change with the position of the active cursor, thereby forming Fig.10 (3) The effect shown.

[0125] like Fig.10(4) shows that the movable active cursor 130 can be moved to any position on both sides of the first straight line 102. In the figure, the active cursor 130 moves to the position BN. In order to clearly reflect the relative position relationship between the position BN and the reference line and realize the measurement based on the reference line, in one embodiment, a vertical line 141 is drawn from the interface operation position BN of the active cursor 130 at the current moment to the first straight line 102, so that the vertical line 141 changes position with the position change of the active cursor 130. In order to realize that the vertical line 141 changes position with the position change of the active cursor 130, in one embodiment, the process of the above steps S260 to S280 includes: the image processing module receives the seventh instruction generated when the seventh operation is input by using the human-computer interaction device, for example, the seventh instruction can be input by a trackball. According to the seventh instruction, the image processing module causes the display of the active cursor 130 to be linked with the seventh operation. When the user moves the trackball, the active cursor 130 has a linkage effect on the ultrasound image. According to the seventh instruction, the display of the active cursor is linked to the seventh operation, and a vertical line 141 is drawn from the interface operation position of the active cursor 130 at the current moment to the first straight line 102. When the moving position of the active cursor 130 changes, the vertical line also changes accordingly.

[0126] like Fig.10 (5) is shown, the display of the active cursor 130 is linked with the seventh operation until the active cursor moves to the target position BN. At this time, the eighth instruction generated when the eighth operation is input by the human-computer interaction device is received. The eighth operation can be the same as the input of the second operation mentioned above, so the eighth instruction can also be the same as the second instruction mentioned above, for example, the eighth instruction is obtained by key input. The corresponding interface operation position is extracted according to the eighth instruction, and the interface operation position associated with the eighth instruction is recorded, indicating that the user has determined that the measurement target position BN needs to be marked on the ultrasound image through the above operation. After recording, a position mark 131 can be marked at the position BN, and the position mark based on the eighth instruction is located at the interface operation position associated with the eighth instruction. Then, the active cursor 130 is moved to the position BL by using the moving trackball. In this process, the display of the position mark 131 is retained at the marked position BN, and the vertical line 141 between the position mark 131 and the first straight line 102 is displayed. When the active cursor 130 is moved to the position BL by using the moving trackball, a vertical line 142 from the interface operation position of the active cursor at the current moment to the first straight line 102 is synchronously drawn. If it is determined that the position BL needs to be measured and recorded, then according to the eighth instruction input by the eighth operation, the interface operation position associated with the eighth instruction is recorded, indicating that the user has determined through the above operation that the measurement target position BL needs to be marked on the ultrasound image.

[0127] like Fig.10(6), according to the seventh instruction, the display of the active cursor 130 is linked to the seventh operation until the active cursor moves to the target position UT. In this process, the display of the position marker 131 is retained at the marked position BN, and the vertical line 141 between the position marker 131 and the first straight line 102 is displayed. It is also possible to draw a position marker 132 at the position BL to display the marked target position, and the vertical line 142 between the position marker 132 and the first straight line 102 is displayed. In the process of linking the display of the active cursor 130 with the seventh operation according to the seventh instruction, a vertical line 143 from the current interface operation position of the active marker 130 to the first straight line 102 can be automatically drawn in the process of moving the active marker 130 to the position UT.

[0128] Each time a position mark is made in the above process, it indicates that a measurement item needs to be measured. Therefore, when measuring the next measurement item, the mark can be made directly by moving the active cursor according to the seventh instruction and recording the moving position according to the eighth instruction. The cyclic measurement operation of the next measurement item can also be switched to by key input. When all measurement items are completed, the measurement end input can be performed by double-clicking or other key operations. Fig.10 It can be seen from the embodiment shown that the vertical line is always perpendicular to the first straight line 102, so the vertical line can be understood as a deformation of the second straight line, for example, the second straight line is changed into a variable line whose length can change with the position of the active cursor. When the active cursor moves at any position on both sides of the first straight line, a vertical line (141, 142, 143) from the interface operation position of the active cursor at the current moment to the first straight line is always drawn, so that the user can more clearly know the reference-based vertical measurement reference required in the measurement process. In addition, in one of the embodiments, after recording the interface operation position associated with the second instruction, or after recording the interface operation position associated with the eighth instruction, the vertical line (141, 142) between the position mark and the first straight line is displayed.

[0129] In the activated current image display window, the display of the first straight line is linked to the first operation, or the display of the active cursor is linked to the sixth operation, and the activation method can refer to the relevant description above, which will not be repeated here. In this way, mutual interference between operations of ultrasound images in the dual-screen display mode can be avoided.

[0130] In step S290, the image processing module 126 obtains a measurement instruction; in step S300, the measurement items of the target tissue are calculated according to the measurement instruction to obtain a calculation result; in step S310, the image processing module 126 outputs the calculation result using the display 107, printer, etc.

[0131] The related measurement instruction is obtained by operating the first straight line or the second straight line and the active mark. For example, the measurement instruction is obtained after recording the first interface operation position associated with the second instruction.

[0132] In this embodiment, the measurement instruction can be obtained by the system according to the measurement operation performed by the user on the ultrasound image. The measurement instruction is obtained by calculating the measurement items related to the target tissue. The medical meaning of some measurement items is described in detail below with reference to the pelvic ultrasound image as an example.

[0133] There are many measurements of anterior pelvic ultrasound images in academic and clinical settings, most of which are related to the diagnosis of anterior pelvic prolapse (Pelvic Organ Prolapsed, POP) and urinary incontinence. The measurement items that may be involved in this embodiment include the following, but are not limited to the following:

[0134] 1) The posterior vesicourethral angle or retrovesical angle (RVA) is the angle between the proximal urethra and the posterior end of the bladder trigone.

[0135] 2) Urethral Tilt Angle (UTA or Urethral Inclination Angle, UI).

[0136] 3) Pubourethral angle (PUA), which is the angle between the central axis of the pubic symphysis and the line connecting the lower edge of the pubic symphysis and the bladder neck.

[0137] 4) Bladder Neck Symphyseal Distance (BSD) or Pubourethral Distance (PUD).

[0138] 5) Pubovesical angle (PVA), which is the angle between the central axis of the pubic symphysis and the line connecting the lower edge of the pubic symphysis and the lowest point of the posterior bladder wall.

[0139] 6) Pubo-vesical distance (PVD) or bladder descent distance (BL Desc.Max).

[0140] 7) Urethral Rotation Angle (URA).

[0141] 8) Bladder Neck Descend (BND).

[0142] 9) Bladder Wall Descend (BWD), etc.

[0143] A large part of these measurements depends on how to establish an appropriate reference coordinate system. For example, PUD and PVD need to uniformly reference the position of the pubic symphysis and its central axis, which depends on the establishment of a reference coordinate system with the central axis of the pubic symphysis as the X-axis.

[0144] The user can select various measurement items, but each measurement item needs to be associated with the corresponding anatomical structure position. For example, when measuring the angle PUA between the pubic symphysis and UVJ (Urethrovesical junction, bladder neck; or, Urethrovesical junction, urethral vesical junction), the distance BSD from UVJ to the X-axis, the urethral inclination angle UTA and the posterior bladder angle RVA, it is necessary to first determine (a) the lower boarder of the pubic symphysis, (b) the central axis of the pubic symphysis, (c) the urethrovesical junction (UVJ), (d) the proximal end of urethra, and (e) the proximal end of the posterior vesical wall. The determination of these positions can be obtained based on the operation inputs of steps S240 and S280 mentioned above. In the above-mentioned embodiments, recording the interface operation position associated with the input instruction indicates that a target position or multiple target positions are determined by operating the first straight line and / or the second straight line. For example, when the first straight line passes through the lower edge of the pubic symphysis, the vesicourethral junction, the proximal end of the urethra, etc., the user records the interface operation position associated with the second instruction according to the second instruction, and inputs the measurement instruction. It is also possible to record the interface operation position associated with the seventh instruction according to the seventh instruction when the active cursor is located at the lower edge of the pubic symphysis, the vesicourethral junction, the proximal end of the urethra, etc., and input the measurement instruction. When the first straight line coincides with the central axis of the pubic symphysis, the user records the interface operation position associated with the second instruction according to the second instruction, and inputs the measurement instruction.

[0145] Based on the input of the measurement operation performed on the ultrasound image, the calculation results of various measurement items can be calculated according to the definition of anatomical medical parameters related to the target tissue and output.

[0146] like Fig.10 The embodiment shown in the figure also provides a variant solution, which provides a simpler method for measuring and calibrating multiple target positions. For the specific process, see Fig.11 shown.

[0147] In step S110, the image processing module 126 in the ultrasound imaging system acquires an ultrasound image, and the ultrasound image includes the target tissue. This step is the same as step S210 mentioned above.

[0148] In step S120, the image processing module 126 in the ultrasound imaging system outputs the ultrasound image to the display for displaying the ultrasound image. This step is the same as the step S220 mentioned above.

[0149] In step S130, the image processing module 126 uses the display 107 to superimpose and display the third straight line on the ultrasound image, and superimpose and display the active cursor on the third straight line. The moving method of the third straight line in this step can refer to the moving operation instructions of all the first straight lines in the above text. The third straight line can be equivalent to the first straight line in the above text, or it can be equivalent to the first straight line rotated and / or moved behind the reference line, for example, Figures 6 to 10 The operations such as the translation of the first straight line, the rotation of the first straight line, etc. performed according to the first instruction or the second instruction will not be repeated here.

[0150] Furthermore, in one embodiment, superimposing and displaying a third straight line on the ultrasound image and superimposing and displaying an active cursor on the third straight line comprises:

[0151] The image processing module displays a fourth straight line placed horizontally on the ultrasound image, and superimposes an active cursor on the fourth straight line. The image processing module receives an eleventh instruction generated when an eleventh operation is input using the human-computer interaction device, and updates the display of the fourth straight line to obtain the third straight line according to the eleventh instruction. During the updating process, the display of the fourth straight line is linked to the input of the eleventh operation. Figures 6 to 9 For the process of updating the display of the fourth straight line according to the eleventh instruction to obtain the third straight line, please refer to the previous section on Figures 6 to 9 In the example, the first straight line is updated according to the first instruction. The details are as follows.

[0152] In one embodiment, the receiving of the eleventh instruction generated when the eleventh operation is inputted by the human-computer interaction device, and updating the display of the fourth straight line to obtain the third straight line according to the eleventh instruction include:

[0153] The image processing module receives a twelfth instruction generated when a twelfth operation is inputted using the human-computer interaction device,

[0154] The image processing module monitors a fifth interface operation position corresponding to the twelfth operation, where the fifth interface operation position is any position within the image display window;

[0155] The image processing module tracks the change of the fifth interface operation position, and

[0156] The image processing module assigns the position of the active cursor as the tracking result of the fifth interface operation position, and redraws the fourth straight line based on the assigned active cursor.

[0157] In this embodiment, the twelfth operation is the same as the third operation mentioned above, and the twelfth instruction is the same as the third instruction. The relevant embodiments of the third operation and the third instruction mentioned above can all be applied here, except that the input of the second straight line is reduced. Fig.12 As described above, on the display interface 811, there is an image display window 812, an ultrasound image 813 is displayed in the image display window 811, and a fourth straight line 814 is displayed at a position 820, but there is no second straight line 604. Figure 6 The intersection 603 of the first straight line 602 and the second straight line 604 is Fig.12 The image processing module receives a twelfth instruction generated when a twelfth operation is inputted using a human-computer interaction device such as a trackball. The twelfth operation is used to control the active cursor 815, monitor the fifth interface operation position corresponding to the twelfth operation, and track the change of the fifth interface operation position. Fig.12 The fifth interface operation position is tracked to change to 818, the position of the active cursor is changed to the fifth interface operation position 818, and based on the changed position of the active cursor, the fourth straight line 814 is re-drawn at the position 819, thereby realizing the translation of the fourth straight line and the active cursor, and the fourth straight line can be moved as a whole to any position in the image display window along with the input of the twelfth operation.

[0158] In one embodiment, the above-mentioned receiving the eleventh instruction generated when the eleventh operation is input using the human-computer interaction device, and updating the display of the fourth straight line to obtain the third straight line according to the eleventh instruction can also include: the image processing module receives the thirteenth instruction generated when the thirteenth operation is input using the human-computer interaction device; the image processing module extracts rotation indication information according to the thirteenth instruction; and the image processing module rotates the fourth straight line according to the extracted rotation indication information with the position of the active cursor as the center.

[0159] like Fig.13As shown, on the display interface 900, there is an image display window 901, an ultrasound image 908 is displayed in the image display window 901, and a fourth straight line 902 is displayed at position 905, and an active cursor 904 is drawn at position 903 on the fourth straight line 902. The fourth straight line 902 is used as a controlled object of human-computer interaction. The image processing module receives a thirteenth instruction generated when a thirteenth operation is input using a human-computer interaction device such as a knob, and the thirteenth operation is used to control the active cursor. According to the thirteenth instruction, rotation indication information is extracted, and the rotation indication information includes angle information, which is used to adjust the angle of the fourth straight line 902 relative to the initial position 905. The image processing module rotates the fourth straight line 902 with the position of the active cursor as the center according to the extracted rotation indication information.

[0160] The process of obtaining the third straight line may need to be completed in combination with the above-mentioned operations of translating the fourth straight line and rotating the fourth straight line, or may only need the above-mentioned operations of translating the fourth straight line or rotating the fourth straight line.

[0161] In step S140, the image processing module receives the ninth instruction generated when the ninth operation is inputted by the human-computer interaction device; in step S150, according to the ninth instruction, the display of the active cursor is linked with the ninth operation. For the linkage mode of the display of the active cursor with the ninth operation in this step, please refer to the above description of Fig.10 The display of the active cursor is linked to the seventh operation mentioned in the above text. The seventh operation and the ninth operation can be the same, and the seventh instruction and the ninth instruction can also be the same. In one embodiment, in the activated current image display window, the display of the active cursor is linked to the ninth operation. For details, please refer to the relevant description of "in the activated current image display window, the display of the first straight line is linked to the first operation, or the display of the active cursor is linked to the sixth operation."

[0162] The operation of the active cursor in this step can also be referred to in the previous article Fig.10 The specific description is that the third straight line is the same as the first straight line. For example, the active cursor can be moved to any position on both sides of the third straight line. Drawing a vertical line from the interface operation position of the active cursor at the current moment to the third straight line so that the vertical line changes position as the position of the active cursor changes can be used in this embodiment.

[0163] In step S160, the image processing module receives at least one tenth instruction generated when the tenth operation is input at least once using a human-computer interaction device; in step S170, the image processing module extracts the corresponding interface operation position according to the tenth instruction; in step S180, the image processing module records at least one interface operation position associated with the tenth instruction. The process of steps S160 to S180 can refer to the relevant descriptions of Figures (3) to (6) in Figure 10 in the previous text, which is the same as the process of the image processing module receiving the eighth instruction generated when the eighth operation is input using a human-computer interaction device, extracting the corresponding interface operation position according to the eighth instruction, and recording the interface operation position associated with the eighth instruction. The tenth operation can be the same as the eighth operation, and the tenth instruction can be the same as the eighth instruction. For details, please refer to the following combined with Fig.14 illustrate.

[0164] Fig.14 A process of measuring using various operations and display modes of the third straight line and active cursor is given, and the specific process is as follows.

[0165] The measurement operation mode is entered by key input or other mode selection operations, and then a fourth straight line placed horizontally and an active cursor set on the fourth straight line are superimposed and displayed on the ultrasound image, such as Fig.14 (A) is shown. An ultrasound image 220 is displayed in the image display window 200. Fig.12 and Fig.13 Regarding the movement operation of the fourth straight line according to the received ninth instruction and the rotation operation of the fourth straight line according to the tenth instruction, the fourth straight line and the active cursor are located at Fig.14 (A), for example, the active cursor is located at the first target position, such as the lower edge of the pubic symphysis, and the fourth straight line is located at the second target position, such as the central axis of the pubic symphysis, thereby obtaining the third straight line. The process of obtaining the third straight line can be combined with Fig.12 The fourth straight line operation and Fig.13 The fourth straight line can be rotated to complete the operation, or it can be done by Fig.12 The fourth straight line translation operation or Fig.13 The operation of rotating the fourth straight line is completed.

[0166] like Fig.14As shown in (B), the movable active cursor 230 can be moved to any position on both sides of the third straight line 202. In the figure, the active cursor 230 moves to the position BN. In order to clearly reflect the relative position relationship between the position BN and the reference line and realize the measurement based on the reference line, in one embodiment, a vertical line 242 is drawn from the interface operation position BN of the active cursor 230 at the current moment to the third straight line 202, so that the vertical line 242 changes position with the position change of the active cursor 230. In order to realize that the vertical line 242 changes position with the position change of the active cursor 230, in one embodiment, the process of the above steps S260 to S280 includes: the image processing module receives the ninth instruction generated when the ninth operation is input by using the human-computer interaction device, for example, the ninth instruction can be input by a trackball. According to the ninth instruction, the image processing module causes the display of the active cursor 230 to be linked with the ninth operation. When the user moves the trackball, the active cursor 230 has a linkage effect on the ultrasound image. According to the ninth instruction, when the display of the active cursor is linked to the ninth operation, a vertical line 242 is drawn from the interface operation position of the active cursor 230 at the current moment to the third straight line 202. When the moving position of the active cursor 230 changes, the vertical line also changes accordingly.

[0167] like Fig.14 (C) shows that the display of the active cursor 230 is linked with the ninth operation until the active cursor moves to the target position BN. At this time, the tenth instruction generated when the tenth operation is input by the human-computer interaction device is received. The tenth operation can be the same as the input of the second operation mentioned above, so the tenth instruction can also be the same as the second instruction mentioned above, for example, the tenth instruction is obtained by key input. According to the tenth instruction, the corresponding interface operation position is extracted, and the interface operation position associated with the tenth instruction is recorded, indicating that the user has determined that the measurement target position BN needs to be marked on the ultrasound image through the above operation. After recording, a position mark 232 can be marked at the position BN, and the position mark based on the tenth instruction is located at the interface operation position associated with the tenth instruction. Then, the active cursor 230 is moved to the position BL by using the moving trackball. In this process, the display of the position mark 232 is retained at the marked position BN, and the vertical line 242 between the position mark 232 and the third straight line 202 is displayed. When the active cursor 230 is moved to the position BL by using the moving trackball, the vertical line 242 from the interface operation position of the active cursor at the current moment to the third straight line 202 is synchronously drawn. If it is determined that the position BL needs to be measured and recorded, then according to the tenth instruction input by the tenth operation, the interface operation position associated with the tenth instruction is recorded, indicating that the user has determined through the above operation that the measurement target position BL needs to be marked on the ultrasound image.

[0168] like Fig.14As shown in (D), according to the ninth instruction, the display of the active cursor 230 is linked to the ninth operation until the active cursor moves to the target position UT. In this process, the display of the position marker 232 is retained at the marked position BN, and the vertical line 242 between the position marker 232 and the third straight line 202 is displayed. It is also possible to draw the position marker 232 at the position BL to display the marked target position, and the vertical line 242 between the position marker 232 and the third straight line 202 is displayed. In the process of linking the display of the active cursor 230 with the ninth operation according to the ninth instruction, a vertical line 243 from the current interface operation position of the active marker 230 to the third straight line 202 can be automatically drawn in the process of moving the active marker 230 to the position UT.

[0169] Each time a position mark is made in the above process, it indicates that a measurement item needs to be measured. Therefore, when measuring the next measurement item, the mark can be made directly by moving the active cursor according to the ninth instruction and recording the moving position according to the tenth instruction, and the cyclic measurement operation of the next measurement item can also be switched to by key input. When all measurement items are completed, the input of the end of measurement can be performed by double-clicking and other key operations. When the active cursor moves at any position on both sides of the third straight line, a vertical line (242, 242, 243) from the interface operation position of the active cursor at the current moment to the third straight line is always drawn, so that the user can more clearly know the reference-based vertical measurement reference required in the measurement process. In addition, in one embodiment, after recording the interface operation position associated with the tenth instruction, the vertical line (242, 242) between the position mark and the third straight line is displayed.

[0170] In the activated current image display window, the display of the third straight line is linked to the eleventh operation, or the display of the active cursor is linked to the ninth operation. The activation method can refer to the relevant description in the previous text, which will not be repeated here. This can avoid mutual interference between the operations of the ultrasound images in the dual-screen display mode. Fig.10In the illustrated embodiment, the marking of at least one target position can be realized continuously through active marking. In the process of the above steps 140 to 180, the image processing module receives the ninth instruction generated when the ninth operation is input by the human-computer interaction device, and according to the ninth instruction, the display of the active cursor is linked with the ninth operation, receives at least one tenth instruction generated when the tenth operation is input at least once by the human-computer interaction device, extracts the corresponding interface operation position according to the tenth instruction, and records at least one interface operation position associated with the tenth instruction, so as to realize the collaborative marking of multiple consecutive target positions. Furthermore, the ninth operation in this embodiment can be a continuous input, so in one of the embodiments, the image processing module receives the ninth instruction generated when the ninth operation is continuously input by the human-computer interaction device, and according to the ninth instruction, the display of the active cursor is continuously linked with the ninth operation.

[0171] In step S190, the image processing module 126 obtains a measurement instruction; in step S191, the measurement items of the target tissue are calculated according to the measurement instruction to obtain a calculation result; in step S192, the image processing module 126 outputs the calculation result using the display 107, a printer, etc. Steps S190, S191, and S192 may be the same as steps S290, S300, and S310, and are not described again here.

[0172] Figure 2 and Fig.11 The only steps provided are the order of execution of the process between the steps, and can also be based on the previous Figure 2 and Fig.11 The steps in the above are adjusted in order to obtain various variations. The above steps are not limited to only following Figure 2 and Fig.11 The steps can be replaced with each other if the basic logic is satisfied, and the execution order can be changed. One or more steps can be repeatedly executed and then the last one or more steps can be executed. These solutions are all variations of the embodiments provided in this article.

Figure 2 or Fig.11The computer program can also be implemented using one or more processors. Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment method can be implemented by means of software plus the necessary general hardware platform. Of course, it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product. The computer software product is carried in a non-volatile computer-readable storage carrier (such as ROM, disk, CD, hard disk, server cloud space), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the system structure and method of each embodiment of the present invention. For example, a computer-readable storage medium stores a computer program thereon, and when the computer program is executed by a processor, it implements the system structure and method based on the aforementioned Figure 2 or Fig.11 Various embodiments of the process shown.

[0174] In the above embodiment, a convenient and fast parameter measurement scheme based on two-dimensional or three-dimensional ultrasound is proposed, which can be applied to the measurement of pelvic floor parameters. This scheme provides a more flexible measurement input method, which can meet the convenient manual measurement method of pelvic floor organ position and descent distance measurement. The default reference line of this method is the horizontal line, and the doctor does not need to manually determine the level; in addition, this method supports distance measurement extending to either side of the reference line; after the measurement is completed, only short lines are displayed at both ends of the distance scale, which greatly reduces the occlusion of the image. This embodiment is an improved parallel line distance measurement method, which can be well applied in the pelvic floor, which is mainly the horizontal reference line distance measurement. This embodiment is further optimized and can be used for combined measurement of prolapse of multiple organs of the pelvic floor, which can save the doctor's time and improve efficiency.
