Description

Parameter measuring method based on ultrasonic image and ultrasonic imaging system

Technical Field

The present invention relates to an ultrasound imaging apparatus, and more particularly, to a method and system for performing parameter measurement in an ultrasound imaging image.

Background

Female pelvic floor dysfunctional diseases are one of the chronic diseases affecting female daily life, including urinary incontinence, fecal incontinence, repeated urinary infection and pelvic organ prolapse. Currently, the ultrasonic examination gradually replaces MRI with the characteristics of repeatability, low price, simplicity, no contraindication and the like as the evaluation means of pelvic floor diseases. In recent years, the development and maturity of pelvic floor ultrasound have become the preferred imaging examination method for FPFD patients.

For ultrasonic pelvic floor examination, it is often necessary to assess the position and mobility of the pelvic floor organs of a patient under various typical motion conditions, and the like. Pubic symphysis is a non-synostotic cartilage structure that connects the two lateral pubic bones together, with little positional movement at rest and in the actions of Valsalva (Valsalva) or anal contraction. The pubic symphysis is therefore an important reference marker structure for pelvic floor ultrasound, and it is common in the industry to use a reference line associated with the pubic symphysis as the basis for distance measurement, regardless of the probe used.

At present, when doctors measure the position of pelvic floor organs or descending distance, a common distance scale is generally used, a horizontal common distance scale is drawn on the lower edge after pubic symphysis, and the horizontal common distance scale is drawn by adopting two points input by users; the vertical distance from the target structure (e.g., bladder neck or uterine nadir) entered by the user on the ultrasound image to the horizontal line is then used to measure a distance term based solely on the horizontal and vertical relationship of the line of sight. Therefore, the operation is not convenient, and the measurement accuracy has no reference basis. Based on the new requirements of doctors on parameter measurement in actual operation, a more convenient and convenient measurement mode is to be provided.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed. The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning.

The ultrasound imaging system shown in figure 1 comprises: a probe 101, a transmitting circuit 101, a transmitting/receiving selection switch 102, a receiving circuit 104, a beam forming module 105, a signal processing module 116, and an image processing module 126. In the ultrasound imaging process, the transmission circuit 101 transmits a delay-focused transmission pulse having a certain amplitude and polarity to the probe 101 through the transmission/reception selection switch 102. The probe 101 is excited by the transmission pulse, transmits an ultrasonic wave to a target tissue (for example, an organ, a tissue, a blood vessel, or the like in a human body or an animal body), receives an ultrasonic echo with information of the target tissue reflected from a target region with a certain delay, and converts the ultrasonic echo back into an electric signal. The receiving circuit 104 receives the electric signals generated by the conversion of the probe 101, obtains ultrasonic echo signals, and sends the ultrasonic echo signals to the beam forming module 105. The beam forming module 105 performs focusing delay, weighting, channel summation and other processing 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 signals processed by the signal processing module 116 are sent to the image processing module 126. The image processing module 126 performs different processing on the signals according to different imaging modes required by a user to obtain ultrasonic image data of different modes, and then performs processing such as logarithmic compression, dynamic range adjustment, digital scan conversion and the like to form ultrasonic images of different modes, such as a B image, a C image, a D image, a doppler blood flow image, an elastic image containing elastic properties of tissues, and the like, or other types of two-dimensional ultrasonic images or three-dimensional ultrasonic images. The elastic image may be obtained by emitting ultrasonic waves to detect the characteristics of shear waves inside the target tissue, or may be obtained by emitting ultrasonic waves to detect the deformation of the target tissue due to an external force, wherein the shear waves may be obtained by vibration of the external force or may be generated by excitation by emitting ultrasonic waves to the target tissue.

In some embodiments of the present invention, the signal processing module 116 and the image processing module 126 may be integrated on one main board 106, or one or more (including the same number) of them may be integrated on one processor/controller chip.

Next, the ultrasound imaging system further includes an external input/output port 108, and the external input/output port 108 is disposed on the main board 106. The ultrasonic imaging system can be connected with the human-computer interaction device through the external input/output port 108, and is used for receiving instruction signals input through the human-computer interaction device through the external input/output port 108, wherein the instruction signals include control instructions for transmitting and receiving time sequences of ultrasonic waves, operation input instructions for editing and labeling ultrasonic images and the like, output instructions for reminding a user and the like, or other instruction types. Generally, the operation instruction obtained when the user performs operation input such as editing, labeling, measuring, etc. on the ultrasound image is used for measurement on the target tissue. The human-computer interaction device may include one or more of a keyboard, a mouse, a scroll wheel, a track ball, a mobile input device (mobile device with touch screen, mobile phone, etc.), a multifunctional knob, etc., so that the corresponding external input/output port 108 may be a wireless communication module, a wired communication module, or a combination thereof. The external input/output port 108 may also be implemented based on USB, bus protocols such as CAN, and/or wired network protocols, among others.

In addition, the ultrasound imaging system may further comprise a display 107, the display 107 being adapted to display ultrasound image data from the image processing module. The display 107 may be a touch screen display. Of course, the ultrasound imaging system can also be connected with another display through an external input/output port to realize a dual-screen display system. In addition, the display in this embodiment may include one display, or may include a plurality of displays, and the number of displays is not limited in this embodiment. The displayed ultrasound image data (ultrasound image) may be displayed on one display, or may be simultaneously displayed on a plurality of displays, or certainly, the ultrasound image data (ultrasound image) may also be displayed on a plurality of displays synchronously, respectively, and this embodiment is not limited herein. In addition, the display displays the ultrasonic images and simultaneously provides a graphical interface for human-computer interaction for a user, one or more controlled objects are arranged on the graphical interface, and the user is provided with a human-computer interaction device to input operation instructions to control the controlled objects, so that corresponding control operation is executed. For example, icons are displayed on the graphical interface, and the icons can be operated by the man-machine interaction device to execute specific functions. Tracking the output of the human-computer interaction device can obtain the interface operation position corresponding to the graphical interface, and perform relevant specific function operation based on the interface operation position, such as positioning the display update of the controlled object, and the like. The interface operation position mentioned in the present text refers to a position on the display interface corresponding to the operation input of the user on the interface object by using the human-computer interaction device. The "position" referred to herein includes orientation information, coordinate information, and/or angle information, etc., for example, the position of the line can be characterized by coordinate information of all pixel points on the line, and can also be characterized by angle information based on a reference line. Therefore, the position change may be a change in the coordinate information or a change in the angle information. The interface object comprises a cursor, a first straight line, a second straight line, a measurement mark and other interface controlled objects. There are many ways to locate the operation position of the interface based on the human-computer interaction device, and different algorithms are used for tracking the position according to different human-computer interaction devices, for example, the position of the operation position of the interface is located by tracking the moving direction and speed of the input operation by using a trackball.

Referring to fig. 2, a flow chart of a method for measuring parameters in an ultrasound image is provided, and the following describes in detail the implementation of the method for measuring parameters in this embodiment with reference to fig. 1.

In step S210, the image processing module 126 in the ultrasound imaging system acquires an ultrasound image, where the ultrasound image includes the target tissue.

As shown in fig. 1, the ultrasound image may be obtained by receiving an ultrasound signal from a target tissue with an ultrasound probe 101. The ultrasonic signal in the present embodiment is not limited to the ultrasonic echo signal explained above with reference to fig. 1, but may be an ultrasonic signal generated in the target tissue by using, for example, a photoacoustic imaging method. Further, tissue of interest herein includes, but is not limited to, pelvic floor tissue, including one or more anatomical tissue structures within the female pelvic cavity, such as, for example, uterus, labia, perineum, pelvic bones, phalanx combinations, and the like. Ultrasound images containing pelvic floor tissue include, but are not limited to, anterior pelvic ultrasound images and posterior pelvic ultrasound images, and may also include medial pelvic cavity ultrasound images. Commonly used measurement items of pelvic floor ultrasound are divided into an anterior pelvic cavity part and a posterior pelvic cavity part, wherein parameter measurement based on an anterior pelvic cavity ultrasound image and a middle pelvic cavity ultrasound image is mainly completed on a human body median sagittal plane image obtained by adopting a trans-labial (trans) or trans-perineal (trans) probe. The parameter measurement based on the posterior pelvic cavity ultrasonic image can adopt an intra-anal (anal) probe to collect images, or more conveniently adopts a Transperineal (transvascular) probe or a Transvaginal (transvascular) probe to collect static three-dimensional images or four-dimensional images, and selects an appropriate section on an axial plane for relevant measurement. Based on the parameter measurement of the posterior pelvic cavity ultrasound image, the description of this embodiment is based on the second case described above, that is, the posterior pelvic cavity ultrasound image obtained by performing image acquisition using a transperineal or transvaginal probe.

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.

See the description above for the display 107. The mode of displaying the ultrasound image in this embodiment is not limited, and for example, the ultrasound image may be displayed on a plurality of displays simultaneously, or only on one display, or may be displayed on a plurality of displays in a synchronized manner in sections, so as to enlarge the observation angle of the ultrasound image. Further, in one embodiment, the image processing module 126 may transmit the ultrasound image to the display in a wireless or wired manner. The display may be a touch display screen on the mobile device. Further, in one embodiment, the ultrasound image is displayed on a first level, which is a software interface layer in addition to non-image data for displaying annotations, labels, text, cursors, measurement scales, and the like. Accordingly, the software interface layer for displaying non-image data such as annotations, labels, texts, cursors, measurement scales, etc. is referred to as a second layer, and the second layer is set to be transparent in the region overlapping with the first layer, so that the ultrasound images can be not shielded, the visibility is enhanced, and the interface friendliness is achieved. Further, the whole layer of the second layer is set to be transparent.

In addition, in one embodiment, as shown in fig. 3, an area for displaying an ultrasound image on the display interface 300 may be independently set as an image display window 301, and a video image is displayed in the image display window 301 or a single frame image is displayed, and besides the image display window, the area may also be used for displaying non-image data such as annotations, labels, texts, and the like, where the ultrasound image of the target tissue after image processing is 302. Of course, there may be 1 or more image display windows on the same display interface to achieve the same-screen multi-window display effect for comparing and browsing images, as shown in fig. 4, two

image display windows

401 and 402 are displayed on the display interface 400 in a double-screen manner, where 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, the current display interface is 1478 × 2897, then 200 × 400 set at the corresponding position is an image display window, and an image display window with the same size is provided in parallel at the same position, wherein one image display window displays a frame of still image and another image display window displays moving video. The video image includes a plurality of frames of ultrasound images.

In step S230, the image processing module 126 displays a first straight line and a second straight line perpendicular to each other on the ultrasound image by superimposing them on the display 107, and the first straight line and the second straight line intersect to generate an intersection. For example, by default, the first line is positioned horizontally and the second line is positioned vertically.

For example, in fig. 3, a first straight line 303 is superimposed on an ultrasound image 302 in an image display window 301, the first straight line 303 is disposed absolutely horizontally, while a second straight line 304 is superimposed, the second straight line 304 is disposed perpendicularly intersecting the first straight line, and the second straight line 304 intersects the first straight line 303 to form an intersection point 305. In addition, the first straight line 303 and the second straight line 304 can be displayed in a distinguishing manner, so that the first straight line 303 and the second straight line 304 cannot be distinguished after the adjustment operation is performed on the first straight line. In fig. 3, the first straight line and the second straight line are displayed in different line types, but may be distinguished by colors. The line type here may include one of a solid line, a broken line, a dot-dash line, and the like. In one embodiment, in fig. 3, the first line 303 and the second line 304 cross the image display window 301 of the ultrasound image, and as a result of the crossing, the first line 303 and the second line 304 cross the boundary 311 of the image display window 301 by a preset distance, the oversized mark can provide a better interaction experience for a user, and the user can more accurately position a position on the ultrasound image.

In order to facilitate the effect of displaying the first line and the second line as the measurement scale, and improve the interaction experience with the user operation, the first line and the second line float on the ultrasound image display, and the ultrasound image is not blocked, in some examples, as shown in fig. 5, the first line 512 and the second line 513 are disposed on the second layer 502, 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 adjustment operation is performed on the first straight line 512, the attribute of the first straight line on the second layer 502 is changed, where the attribute includes parameters such as size, line type, color, visibility, and the like, and the adjustment of the attribute can change the display result of the first straight line or the second straight line, including the display position and the display form. The first and second slices are superimposed to form the rightmost display of fig. 5, i.e., the first and

second lines

512 and 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 in which the first straight line 512 and the second straight line 513 can be displayed and operated on the second layer 502 may be equal to or larger than the area range of the single image display window 503 on the first layer 501. The range of areas where the first straight line 512 and the second straight line 513 are displayable and operable on the second level 502 may include: the length of the first straight line 512 and the second straight line 513 is used as the length and width of the rectangle or square area, or the longest one of the first straight line 512 and the second straight line 513 is used as the diameter of the circle area.

As shown in fig. 4, in a multi-screen display, for example, two

image display windows

401 and 402 in fig. 4, where the ultrasound images are 411 and 412, respectively, the first straight line and the second straight line superimposed on the

ultrasound images

411 and 412 are, respectively, a first straight line 431 and a second straight line 421 located in the image display window 401, and a first straight line 432 and a second straight line 442 located in the image display window 402. In order to avoid confusion in the measurement of the images in the multi-screen display mode, in one embodiment, the first line and/or the second line can be adjusted only by activating the image display window, so as to perform the measurement on the ultrasound image. For example, when 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 when 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. The first line and/or the second line may be adjustable within the activated image display window.

The current image display window is activated during the adjustment of the first straight line, and the activation may be implemented as follows.

Firstly, an image processing module determines an interface operation position corresponding to a first operation or a second operation input by using a human-computer interaction device; secondly, determining the image display window according to the interface operation position associated with the first operation or the second operation, and using the image display window as the current image display window; then, the current image display window is activated. In the 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 where the current image processing window is located is automatically activated, independent activation operation is not required to be performed through the human-computer interaction device such as a key, the use experience of a user is improved, and the measurement operation is more friendly.

In step S240, the image processing module 126 receives a first instruction generated when a first operation is input using the human-computer interaction device. In step S250, the display of the first straight line and/or the second straight line is updated in accordance with the first command, and the display of the first straight line and/or the second straight line is interlocked with the input of the first operation. And updating the display of the first straight line and/or the second straight line, wherein the purpose is that when the input of the first operation is changed, the display of the first straight line and/or the second straight line is changed, and the second straight line and the first straight line are perpendicularly intersected all the time in the updating process of the first straight line and/or the second straight line. For example, when the first command is generated by continuously inputting the first operation using the trackball, the display of the first straight line and/or the second straight line may be changed accordingly.

In this embodiment, the intersection point formed by the first straight line and the second straight line or the first straight line can be used as the controlled cursor, and the cursor icon is not required to be displayed on the interface separately to be used as the controlled interface object except for the first straight line and the second straight line, so that the first straight line and the second straight line can be used as the scale or the cursor. When the man-machine interaction device is used for operation input, the operation can be performed on the intersection point of the first straight line and the second straight line by default, and the operation is different from the operation performed on the intersection point of the first straight line and the second straight line, so that the interface display can be simplified, and the operation is convenient for a user.

In the process from step S240 to step S250, the first instruction generated during the first operation is input by using the human-computer interaction device, so that the overall movement of the first straight line and the second straight line, the independent movement of the first straight line or the second straight line, the rotation operation of the first straight line, and the like can be realized. The following is a specific example.

For example, in one embodiment, the above-mentioned process from step S240 to step S250 realizes the integral movement of the first straight line and the second straight line in the following manner:

first, the image processing module receives a third instruction generated when a human-computer interaction device is used to input a third operation, where the third operation in this embodiment may be implemented by using an operation on a trackball. The input may be continued for the operation of the trackball.

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

and then, assigning the intersection point position of the first straight line and the second straight line as a tracking result of the second interface operation position, and redrawing the first straight line and the second straight line based on the reassigned intersection point. Therefore, the linkage effect is generated by utilizing the input of the human-computer interaction equipment and the integral operation of the first straight line and the second straight line.

As shown in fig. 6, on the display interface 600, there is an image display window 601, an ultrasound image 608 is displayed within 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. And taking the intersection point 603 as a controlled object of human-computer interaction. The image processing module receives a third instruction generated when a third operation is input by using a human-computer interaction device such as a trackball, the third operation is used for controlling the intersection point 603, monitoring a second interface operation position corresponding to the third operation, tracking the change of the second interface operation position to 612 in fig. 6, changing the position of the intersection point 603 of the first straight line 602 and the second straight line 604 to the second interface operation position 612, and redrawing the first straight line 602 and the first straight line 604 based on the changed intersection point position, so that the integral movement of the first straight line and the second straight line is realized, and the first straight line and the second straight line can integrally move to any position in the image display window along with the input of the first three operations. In this embodiment, the overall movement of the first straight line and the second straight line may be performed in a manner of moving to the target position in one step, or may be performed in two steps to reach the target position, for example, the intersection point 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 point 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 point is moved to the target position, which also falls into the protection range of this embodiment. It is obvious that the third operation includes one operation input, and may also include a continuous input of a plurality of operations. The second interface operation position may include one interface operation position, or may include a plurality of interface operation positions, and the plurality of interface operation positions may be continuous or discontinuous.

For another example, in one embodiment, the following manner is adopted to implement the translation of the first straight line in the process from step S240 to step S250:

firstly, the image processing module receives a fourth instruction generated when a human-computer interaction device is used for inputting a fourth operation, wherein the fourth operation in the embodiment can be realized by using the operation of a trackball;

secondly, the image processing module monitors a 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 position of the third interface operation position in the horizontal direction is unchanged;

and thirdly, assigning the position of the intersection point of the first straight line and the second straight line as a tracking result of the operation position of the third interface, and redrawing the first straight line based on the assigned intersection point.

As shown in fig. 8, in panel a, a first straight line 81 is displayed at a position 83 on the display interface, while a second straight line 82 is displayed perpendicularly intersecting the first straight line 81, with the intersection position at the bladder neck. In the diagram B, the image processing module receives a fourth instruction generated when a fourth operation is input by using a human-computer interaction device such as a trackball, monitors a third interface operation position corresponding to the fourth operation, tracks the change of the third interface operation position in the vertical direction, and keeps the position of the third interface operation position in the horizontal direction unchanged, namely, the intersection point in the diagram B changes to a position 85 along a second straight line, assigns the position of the intersection point of the first straight line and the second straight line as the tracking result of the third interface operation position, and redraws 81 the first straight line at the position 85 based on the assigned intersection point, wherein the second straight line 82 is fixed during the movement. In this embodiment, the intersection 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. Therefore, through the embodiment, the measuring mode that the first straight line gradually moves along the second straight line can be presented, the measuring precision is improved, the effect that the second straight line is used as a measuring reference is realized, the operation of a user is facilitated, and the operation experience is improved. The user is presented with a clearer and clearer position change process, accuracy determination during measurement operation by a doctor is facilitated, and input of misoperation is reduced, which is shown in the process from A, B to C in sequence in fig. 8. It is obvious that the fourth operation includes one operation input, and may also include a continuous input of a plurality of operations. The third interface operation position may include one interface operation position, or may include a plurality of interface operation positions, and the plurality of interface operation positions may be continuous or discontinuous.

Similarly, for example, in one embodiment, the following manner is adopted to implement the translation of the second straight line in the process from step S240 to step S250:

firstly, the image processing module receives a fifth instruction generated when a human-computer interaction device is used for inputting a fifth operation, wherein the fifth operation in the embodiment can be realized by using the operation of a track ball; secondly, the image processing module monitors a 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 position of the fourth interface operation position in the vertical direction is unchanged; and thirdly, assigning the position of the intersection point of the first straight line and the second straight line as a tracking result of the operation position of the fourth interface, and redrawing the second straight line based on the assigned intersection point. Not specifically described herein is how to translate the second line alone, as described above in relation to moving the first line in fig. 8, the fifth and fourth operations may be the same, and the fifth instruction may be the same as the fourth instruction. It is apparent that the fifth operation may also include one-time operation input or continuous input of a plurality of operations. The fourth interface operation position may also include one interface operation position or a plurality of interface operation positions, and the plurality of interface operation positions may be continuous or discontinuous.

The second straight line can be translated by adopting the embodiment, and the integral translation of the first straight line and the second straight line can be realized by further combining the translation of the first straight line and the translation of the second straight line, as shown below.

The above-mentioned process from step S240 to step S250 realizes the integral movement of the first straight line and the second straight line in the following manner:

thirdly, assigning the position of the intersection point of the first straight line and the second straight line as a tracking result of the operation position of the third interface, and redrawing the first straight line based on the assigned intersection point;

then, the image processing module receives a fifth instruction generated when the human-computer interaction device is used for inputting a fifth operation again, wherein the fifth operation in the embodiment can be realized by using the operation on the trackball;

secondly, the image processing module monitors a 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 position of the fourth interface operation position in the vertical direction is unchanged;

and thirdly, assigning the position of the intersection point of the first straight line and the second straight line as a tracking result of the operation position of the fourth interface, and redrawing the second straight line based on the assigned intersection point.

The fourth instruction and the fifth instruction output by the fourth operation and the fifth operation which are input twice in the above process may contain different instruction information, for example, the input of the two operations is distinguished by the operation of the trackball in different directions.

For example, in one embodiment, the rotation of the first line and the second line is realized in the following manner in the process from step S240 to step S250:

firstly, the image processing module receives a sixth instruction generated when a human-computer interaction device is used for inputting a sixth operation;

secondly, the image processing module extracts rotation indication information according to the sixth instruction;

then, the image processing module rotates the first straight line or the second straight line with the intersection point as a center according to the extracted rotation instruction information.

As shown in fig. 7, on the display interface 700, there is an image display window 701, an ultrasound image 708 is displayed within the image display window 701, and a first straight line 702 is displayed at a position 71 and a second straight line 704 is displayed at a position 73, and an intersection point of the first straight line 702 and the second straight line 704 is 703. The first straight line 702 is used as a controlled object for man-machine 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, the sixth operation is used for controlling the intersection point 703, and rotation instruction information including angle information for adjusting the angle of the first straight line 702 with respect to the initial position 71 or the angle of the second straight line 704 with respect to the initial position 73 is extracted according to the sixth instruction. The image processing module rotates the first straight line 702 or the second straight line 704 around the intersection of the first straight line and the second straight line according to the extracted rotation instruction information, thereby realizing rotation adjustment of the first straight line and/or the second straight line. Also, as the first line 702 rotates, the second line may also rotate in synchronization with the rotation of the first line, for example from position 73 to position 74, thereby ensuring that the first line always intersects the second line perpendicularly.

In order to ensure that the first line and the second line provided to the user provide absolute measurement references, and to improve accuracy, in one embodiment the first line and the second line always intersect perpendicularly. For example, in the above steps S240 and S250, the image processing module 126 receives a first instruction generated when a first operation is input by using the human-computer interaction device, and updates the display of the first straight line according to the first instruction so that the first straight line and the second straight line are always perpendicularly intersected by one of the following manners:

as shown in fig. 7, during the process of adjusting the first straight line 702, the second straight line 704 changes with the position change of the first straight line 702 and always perpendicularly intersects with the first straight line 702, and in fig. 7, when the first straight line 702 rotates from the position 71 to the position 72, the second straight line 704 also synchronously rotates from the position 73 to the position 74; and,

as shown in fig. 8, when the first straight line 702 is adjusted to rotate from the position 71 to the position 72, the second straight line 704 always moves at the position 73, and 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.

The target position mentioned herein is a position to which the user desires to adjust the interface object when performing an adjustment input operation on the interface object through the human-computer interaction device, for example, a relevant anatomical structure of a target tissue such as a pubic symphysis lower edge, a pubic symphysis middle axis, and the like on the ultrasound image. When a user performs input operation on an interface object (including a controlled object) through the human-computer interaction device, a corresponding interface operation position is generated on the display interface. The interface operation position may be a pixel coordinate position, or a neighborhood position region formed by a plurality of pixels.

Through each embodiment, the measuring effect that the first straight line and/or the second straight line are linked along with the input operation of the user can be realized, the operation experience is improved, and the user can accurately position the image position to perform the measuring operation conveniently.

In the above embodiments, the rotation of the first straight line, the translation of the first straight line, and the integral movement of the first straight line and the second straight line are respectively realized. The third operation, the fourth operation, the fifth operation and the sixth operation may be continuous input of instructions by a user based on the human-computer interaction device. Therefore, the third instruction, the fourth instruction, the fifth instruction and the sixth instruction may be continuous input performed by the user based on the human-computer interaction device, where the continuous input mentioned herein represents an operation that the user continuously performs instruction input using the human-computer interaction device for a period of time, and for example, the continuous input may include a continuous input movement operation using a trackball by the user, and a continuous input of position change information using a keyboard by the user, so that an interface object displayed on the interface may present a continuously moving display effect on a screen through the continuous input, and interaction experience may be improved. Therefore, in steps S240 and S250, the image processing module receives a continuous input related to the first command 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 interlocked with the continuous input.

Referring to fig. 2, the method for measuring parameters based on ultrasound images in this embodiment may further include steps S260, S270, and S280, configured to confirm the position after the linkage operation is performed on the first straight line, and obtain a measurement instruction, so as to implement calculation on ultrasound image measurement items.

In step S260, the image processing module receives a second instruction generated when a second operation is input using the human-computer interaction device. In step S270, the image processing module extracts a corresponding first interface operation position according to the second instruction. In step S280, the image processing module records a first interface operation position associated with the second instruction. As specifically illustrated in conjunction with fig. 8 and 9.

As shown in fig. 8 and 9, an embodiment in which an operation instruction is input using a first straight line and a second straight line is provided. The oval circles in the figure indicate the pubic symphysis and the black dots indicate the bladder neck. The image processing module 126 receives a first instruction generated when a first operation is input using the human-computer interaction device, updates the first straight line 81 according to the first instruction, and records a position determined by measurement according to a second instruction generated when a second operation is input using the human-computer interaction device.

In fig. 8, in panel a, the intersection of the first and second lines is at the location 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 point is not at the bladder neck position), the intersection point 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 by using the human-computer interaction device, which can be specifically referred to the related description above.

In the process of changing from the a diagram to the B diagram, after the intersection of the first straight line and the second straight line is moved to a desired or target position, the user needs to mark the position and record the position for measurement calculation with respect to the ultrasound image. Therefore, the user can input a second operation by using the human-computer interaction device to confirm the position, wherein the second operation can provide instruction input through hardware such as keys, and a set setting key on a keyboard of an ultrasonic device is commonly used. The image processing module receives a second instruction generated when the human-computer interaction device is used for inputting a second operation, and extracts a corresponding first interface operation position, namely a position 83 according to the second instruction, wherein the first interface operation position is used as data for measuring the ultrasonic device, and the subsequent measurement instruction is convenient to generate.

When the intersection of the first line and the second line is moved to the position 85, the first line is translated downward, so that the user can easily see the marked position on the interface, and therefore, when the first line or the intersection of the first line and the second line is moved, a position mark 87 is marked at the initial position (namely, the bladder neck position) where the intersection of the first line and the second line is located. And continuing the measurement operation, when the third interface operation position corresponding to the fourth operation related to the fourth instruction is monitored according to the received four instructions, and the change of the third interface operation position is tracked, for example, the change of the third interface operation position in the vertical direction is tracked in fig. 8, the location of the third interface operation position in the horizontal direction is unchanged, that is, the intersection point in the B diagram changes to a position 84 along a second straight line, and when the user determines that the first straight line reaches the position 84 and passes another target position (for example, the lower edge of the pubic bone combination), the second operation is input by 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 by using the human-computer interaction device, and extracts the corresponding first interface operation position, that is, according to the second instruction, the position 84. The image processing module records a first interface operational position 84 associated with the second instruction, representing a position of a lower margin of the pubic symphysis determined using the first line. After the measurement operation is completed, when a second instruction input by the user is received, the representation in fig. 8 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, or hidden, or deleted, and when the first straight line 81 is hidden or deleted, a position mark 88 is marked at a corresponding position, thereby forming a D-diagram. In one embodiment, there is only one first straight line in the same image display window. Based on the position between the

position markers

87 and 88, corresponding measurement instructions can be obtained.

Fig. 9 shows an embodiment mainly directed to the rotation operation of the first straight line 91. Both the translation operation and the rotation operation belong to the movement operation, and therefore, the first instruction to update the first linear display includes: sixth instructions for rotating the first straight line, the moving of the first straight line comprising: the image processing module receives a sixth instruction generated when a human-computer interaction device is used for inputting a sixth operation, and extracts rotation indication information, such as angle information of rotation from a position 93 to a target position 94, according to the sixth instruction; the first straight line 91 is displayed in an updated state at the interface operation position 94 in conjunction with the sixth command, so that the first straight line 91 is rotated from the first position 93 at the present position to the target position 94, as shown in the process from a to B in fig. 9. During the rotation, the first straight line 91 is rotated around the intersection of the first straight line and the second straight line in accordance with the angle information included in the extracted rotation instruction information so as to coincide with the reference line (the red dotted line 910 in fig. 9). Of course, the second line may also be rotated in the manner described above. The second straight line 92 is automatically adjusted to be perpendicular to the first straight line 91 when the rotation reaches the target position 94, or the perpendicular relationship of the second straight line 92 is automatically adjusted along with the position change of the first straight line 91 in the process of not reaching the target position, so that the first straight line 91 is always perpendicular to the second straight line 92 when the rotation operation is executed, and the second straight line 92 is also rotated from the position 95 or synchronously rotated along with the first straight line to the position 96. In rotating the first straight line 91 according to the fifth instruction, the first straight line 91 is rotated centering on the intersection of the first straight line 91 and the second straight line 92. If the position of the bladder neck is to be marked, at this time, when the position of the reference line is determined after the first straight line is overlapped with the red reference line 910, the position is confirmed by inputting a second operation through the human-computer interaction device (for example, confirmation through key input), and the image processing module receives a second instruction generated when the second operation is input through the human-computer interaction device, and extracts a corresponding first interface operation position, namely the position 94, according to the second instruction. The image processing module records a first interface operational position 94 associated with the second instructions indicating that the user has confirmed the position of the at least one reference line or a target position to be measured, such as the pubic symphysis axis position determined using the first line. When the first line is translated to continue marking the location of the bladder neck, the location of the marked location can be recorded by marking a location mark 97 (in fig. C) on the second line for recording the location as the determined mid axis of pubic symphysis after the first line is moved in order to allow the user to view the marked location on the image. When the marking of the bladder neck position is continued, receiving a fourth instruction generated when a human-computer interaction device is used for inputting a fourth operation, monitoring a third interface operation position corresponding to the fourth operation, wherein the third interface operation position is unchanged in the horizontal direction, and the C figure shows that the intersection point of the first straight line and the second straight line always moves on the second straight line and tracks the change of the third interface operation position in the vertical direction; assigning the position of the intersection point of the first straight line and the second straight line as a tracking result of the third interface operation position, redrawing the first straight line 91 based on the assigned intersection point, thereby presenting a translation display effect of the first straight line along the second straight line until the first straight line passes through the bladder neck when the first straight line is at the position 95, receiving a second instruction generated when the second operation is input by using a human-computer interaction device by using an image processing module, for example, receiving a confirmation instruction performed by a user through key clicking operation, then extracting the corresponding first interface operation position according to the second instruction by using the image processing module, recording the first interface operation position associated with the second instruction, and representing that the user has confirmed the position of at least one reference line or a target position to be detected, for example, the position of the bladder neck is determined by using the first straight line. The position that has been marked can then be recorded by marking the position marker 98 on a second line for obtaining measurement instructions for performing measurement calculations with respect to the ultrasound image. The position mark may appear based on one operation input of the user or based on two operation inputs of the user, which is not limited in this embodiment, that is, the second instruction generated when the second operation is input by using the human-computer interaction device is received, and the second instruction may be input by a single instruction or input by multiple instructions. For example, the marking of the position mark on the ultrasound image may be realized by performing one operation input through a key, or may be realized by performing two consecutive operation inputs. The distance relationship between the bladder neck position and the central axis of pubic symphysis can be obtained from the

position markers

97 and 98 and used to calculate the corresponding measurement terms.

As shown in fig. 8 and 9, in one embodiment, after recording the interface operation position associated with the second instruction, the image processing module further includes:

position markers (87, 88, 97, 98) are drawn, and the position markers (87, 88, 97, 98) are located on the second straight line (82, 92). The position marker may be a line segment, or a cross marker or the like may be used as an icon for position identification.

Further, in one embodiment, the image processing module eliminates redundant second lines, avoids the marking obscuring the ultrasound image, displays portions (89, 99) of the second lines, the portions (89, 99) of the second lines being located between two position markers and/or between a position marker and a first line.

The red dotted line 910 in fig. 9 provides a position prompt mark of the central axis of pubic symphysis, which is obtained by automatic image segmentation and automatically provided by the system, so that a certain reference can be provided when a user performs coordinate positioning or reference line positioning in image measurement, and the system has a relatively practical clinical value. Therefore, in some variations of this embodiment, a position cue marker may also be displayed on the ultrasound image. The position cue marks can be obtained by automatic image segmentation of the system, and can also be obtained in an automatic scanning process in a system and manual mode.

In the embodiments provided above, the point-to-point distance measurement, or the point-to-line measurement, and the combination measurement of the two can be realized by the operation of the first straight line and the second straight line, which is very simple and easy to operate, and: the absolute horizontal reference line can be obtained, and the measurement accuracy is improved. After the measurement is finished, the two ends of the ruler are short lines, for example, the position of the position mark and the mode of displaying the second straight line part can reduce image shielding; the distance end point reference line can move at two sides of the distance starting point short line, so that the distance can be measured at two sides, and the application of the basin bottom is met. The two perpendicular cursor lines (the first line and the second line) are different in color or line type, and the user knows which direction to rotate the minimum angle in any way to quickly coincide the measuring cursor with the reference line.

In the embodiment shown in FIG. 9, when the first straight line 92 moves to the pubic symphysis axis position at the position 94, the property of the first straight line 92 may be altered when recording the interface operation position associated with the second instruction according to the input of the second instruction, the first straight line being located at the interface operation position associated with the second instruction. For example, the line shape of the first straight line 92 is changed to prompt the user that the position of the reference line has been confirmed. Changing the attribute of the first line includes at least one of the following ways: the operation attribute of the first straight line is set to be immovable, and the line type of the first straight line is set to be a preset line type. See in particular the measurement process shown in fig. 10.

In order to facilitate the measurement operation, after the position marks (87, 88, 97, 98) are obtained by marking at least once during the movement process of the first straight line shown in fig. 8 and 9, the first straight line can move not only on one side of the position mark on the second straight line, but also on both sides of the position mark on the second straight line, that is, during the translation process of the first straight line, the position of the intersection point of the first straight line and the second straight line can be arbitrarily moved on the first straight line or the second straight line.

Fig. 10 shows a process of performing measurement by using various operation and display modes of the first straight line and the second straight line, and a specific flow is as follows.

The operation through the key input or other mode selection enters the measurement operation mode, and the horizontally disposed first straight line 102 and the vertically disposed second straight line 101 are displayed in an overlapped manner on the ultrasound image, as shown in fig. 10 (1). Different colors/line types may be used between the first line and the second line to indicate the difference. The ultrasound image 120 is displayed in the image display window 100.

As shown in fig. 10(2), in combination with the aforementioned operation of moving the first straight line and/or the second straight line according to the received first command, so that the intersection point of the first straight line and the second straight line is located at the target position, for example, the lower edge of the pubic symphysis, the specific operation can be referred to the related description of fig. 6, fig. 7, fig. 8 and fig. 9.

As shown in fig. 10(3), assuming that the intersection point of the first straight line 102 and the second straight line 101 in fig. 10(2) moves to the first target position (e.g., the lower pubic symphysis edge), and the first straight line is also located at the second target position (e.g., the middle pubic symphysis axis), the first interface operation position, i.e., the second target, associated with the second instruction may be recorded as a reference of the production measurement instruction according to the reception of the second instruction. Therefore, in fig. 10(3), after receiving the second instruction, the image processing module records a first interface operation position where the first straight line is currently located, for example, a position of a central axis of pubic symphysis. The first line at this position is taken or configured as a reference line and the properties of the first line are modified, characterizing the first line 102 as marked as the reference line. Altering the property of the first line includes at least: the first line is configured to be immovable, and an attribute of the first line is set to one of preset attributes. The property settings may be changes to color, line type, etc., e.g. changing the line type of the first straight line 102 from a dashed line to a dotted line. Further, in one embodiment, a movable active cursor 130 is drawn at the intersection of the first line 102 and the second line 101. The movable active cursor can be moved to any position on either side of the first line 102. In order to facilitate the operation of the movable cursor 130, the image processing module reduces the cursor, or adjusts the second straight line to be hidden, or deletes the second straight line, or changes the second straight line to a changing line whose length can change with the position of the movable cursor, thereby forming the effect shown in fig. 10 (3).

As shown in fig. 10(4), the movable cursor 130 can be moved to any position on both sides of the first straight line 102, in which the movable cursor 130 is moved to the position BN, and in order to clearly reflect the relative position relationship between the position BN and the reference line, the measurement based on the reference line is implemented, in one embodiment, a vertical line 141 from the interface operation position BN where the movable cursor 130 is located at the current time to the first straight line 102 is drawn, so that the vertical line 141 changes in position with the change in the position of the movable cursor 130. In order to realize the position change of the vertical line 141 with the position change of the movable cursor 130, in one embodiment, the process from the step S260 to the step S280 includes: the image processing module receives a seventh instruction generated when the seventh operation is input by using the human-computer interaction device, and the seventh instruction can be input through a track ball. The image processing module causes the display of the movable cursor 130 to be linked with the seventh operation according to the seventh instruction. When the user moves the trackball, the linkage effect of the movable cursor 130 on the ultrasound image is that when the display of the movable cursor is linked with the seventh operation according to the seventh instruction, a vertical line 141 from the interface operation position where the movable cursor 130 is located to the first straight line 102 is drawn, and when the movement position of the movable cursor 130 is changed, the vertical line is changed accordingly.

As shown in fig. 10(5), the display of the active cursor 130 is linked with the seventh operation until the active cursor moves to the target position BN, and at this time, an eighth command generated when the eighth operation is input by the human-computer interaction device is received, and the eighth operation may be the same as the input of the aforementioned second operation, so that the eighth command may also be the same as the aforementioned second command, for example, the eighth command is obtained by inputting a key. And extracting the corresponding interface operation position according to the eighth instruction, and recording the interface operation position associated with the eighth instruction, which indicates that the user determines that the measurement target position BN needs to be marked on the ultrasonic image through the operation. After recording, a position mark 131 may be marked at the position BN, the position mark based on the eighth instruction being located at the interface operation position associated with the eighth instruction. The movable cursor 130 is then moved to the position BL by means of the moving trackball, during which the display of the position mark 131 remains at the already marked position BN, while the vertical line 141 between the position mark 131 and the first straight line 102 is displayed. When the movable cursor 130 is moved to the position BL by using the moving trackball, a vertical line 142 from the interface operation position where the movable cursor is located at the current time to the first straight line 102 is synchronously drawn. If the position BL is determined to need to be measured and recorded, recording an interface operation position associated with an eighth instruction according to the eighth instruction input by the eighth operation, indicating that the user determines that the measurement target position BL needs to be marked on the ultrasonic image through the operation.

As shown in fig. 10(6), the display of the active cursor 130 is interlocked with the seventh operation according to the seventh command until the active cursor moves to the target position UT. The display of the position mark 131 is retained at the position BN already marked in this process, while the vertical line 141 between the position mark 131 and the first line 102 is displayed. It is also possible to draw a position mark 132 at the position BL for displaying the target position that has been marked, while displaying a vertical line 142 between the position mark 132 and the first straight line 102. In the process of linking the display of the active cursor 130 with the seventh operation according to the seventh instruction, the vertical line 143 from the interface operation position where the active marker 130 is located to the first straight line 102 at the present time may be automatically drawn in the process of moving the active marker 130 to the position UT.

In the process, each time a position mark is carried out, the measurement of one measurement item is represented, so that the marking can be directly carried out by moving the movable cursor according to the seventh instruction and recording the moving position according to the eighth instruction when the measurement of the next measurement item is carried out, and the cyclic measurement operation of the next measurement item can be switched by key input. When all the measurement items are operated, the measurement end input can be performed by double-click or other key operation. As can be seen from the embodiment shown in fig. 10, the vertical line is always perpendicular to the first straight line 102, and therefore, the vertical line can be understood as a deformation of the second straight line, for example, changing the second straight line into a changing line whose length can be changed with the position of the active cursor. When the movable cursor moves at any position on two sides of the first straight line, the vertical lines (141, 142 and 143) from the interface operation position where the movable cursor is located at the current moment to the first straight line are drawn all the time, so that a user can more clearly know that the reference-based vertical measurement reference needed in the measurement process appears. Further, in one embodiment, vertical lines (141, 142) between the position markers and the first line are displayed after the interface operation position associated with the second instruction is recorded, or after the interface operation position associated with the eighth instruction is recorded.

In the activated current image display window, the display of the first straight line is linked with the first operation, or the display of the movable cursor is linked with the sixth operation, and the activation manner can be referred to the related description, and will not be described herein. This avoids interference between the ultrasound image operations in the two-screen display mode.

In step S290, the image processing module 126 obtains a measurement instruction; in step S300, calculating a measurement item of the target tissue according to the measurement instruction, and obtaining a calculation result; in step S310, the image processing module 126 outputs the calculation result using the display 107, the printer, or the like.

And obtaining related measurement instructions through the operation of the first straight line or the second straight line and the movable mark. For example, the measurement instruction is obtained after recording the first interface operation position associated with the second instruction.

In this embodiment, the measurement instruction may 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 measurement items related to target tissues, and the medical meaning of part of the measurement items is described in detail below by taking pelvic ultrasound images as an example.

There are numerous academic and clinical measurements of anterior Pelvic ultrasound images, most of which are associated with diagnosing anterior Pelvic prolapse (POP) and Urinary Incontinence (Urinary Incontinence). The measurement items that may be involved in the present embodiment include, but are not limited to, the following items:

1) the posterior urethral Angle or bladder Angle (RVA), the Angle between the proximal urethra and the posterior end of the trigone.

2) Urethral Inclination Angle (UTA or Urehral incorporation Angle, UI).

3) Pubic Urethral Angle (PUA), the Angle between the central axis of the symphysis pubis and the line connecting the lower edge of the symphysis pubis and the bladder neck.

4) Bladder Neck Distance (BSD) or puborethral Distance (PUD).

5) Pubic bladder Angle (PVA), the Angle between the central axis of pubic symphysis and the line connecting the lower edge of pubic symphysis and the lowest point of the posterior wall of the bladder.

6) Pubic bladder Distance (PVD), or bladder descent Distance (BL desc.

7) Angle of Rotation of Urethra (URA).

8) Bladder Neck descent distance or Bladder Neck mobility (BND). And

9) bladder Wall descent distance (BWD), etc.

These measurements depend in large part on how to establish an appropriate reference coordinate system. For example, PUD and PVD require a uniform reference to the pubic symphysis and the location of its central axis, relying on the establishment of a reference coordinate system with the central axis of the pubic symphysis as the X-axis.

The user may select various measurements, but each measurement needs to be associated with a corresponding anatomical location, for example, at measurements of the pubic symphysis sum UVJ (urinary cervical Junction, or urethral-bladder Junction) angle PUA, the distance BSD of UVJ from the X-axis, the urethral inclination angle UTA, and the bladder relief angle RVA, it is necessary to determine first (a) the inferior pubic symphysis margin (SP), (b) the medial pubic symphysis axis (SP), (c) the urinary bladder urethra Junction (Uvrnasal j UVj), (d) the Proximal urethra (Proximal of urethra), and (e) the posterior bladder margin (Proximal of cervical). And the determination of these positions may be obtained based on the aforementioned operation input of step S240 to step S280. In the above embodiments, the recording of the interface operation position associated with the input instruction is characterized by determining a target position or a plurality of target positions 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 urinary bladder urethra junction, the proximal urethra end, and the like, the user records the interface operation position associated with the second instruction according to the second instruction, and performs the input of the measurement instruction.

Fig. 14 shows a process of performing measurement by using the above third line and various operation and display modes of the movable cursor, and a specific flow is as follows.

The operation by the key input or other mode selection enters the measurement operation mode, and the horizontally placed fourth line and the active cursor set on the fourth line are displayed superimposed on the ultrasound image, as shown in fig. 14 (a). The ultrasound image 220 is displayed in the image display window 200. In conjunction with the moving operation of the fourth straight line performed according to the received ninth instruction and the rotating operation of the fourth straight line performed according to the tenth instruction in the foregoing with respect to fig. 12 and 13, the fourth straight line and the movable cursor are located at the target position in fig. 14(a), for example, the movable cursor is located at the first target position, for example, the lower pubic symphysis edge, and the fourth straight line is located at the second target position, for example, the middle pubic symphysis axis, so as to obtain the third straight line.

As shown in fig. 14(B), the movable cursor 230 can be moved to any position on both sides of the third straight line 202, in which the movable cursor 230 is moved to a position BN, and in order to clearly reflect the relative position relationship between the position BN and the reference line, the measurement based on the reference line is implemented, in one embodiment, a vertical line 242 from the interface operation position BN where the movable cursor 230 is located at the current time to the third straight line 202 is drawn, so that the vertical line 242 changes in position with the change in the position of the movable cursor 230. In order to realize the position change of the vertical line 242 with the position change of the movable cursor 230, in one embodiment, the process from the step S260 to the step S280 includes: the image processing module receives a ninth instruction generated when the ninth operation is input by the human-computer interaction device, and the ninth instruction can be input through a track ball. The image processing module causes the display of the movable cursor 230 to be interlocked with the ninth operation according to the ninth instruction. When the user moves the trackball, the linkage effect of the active cursor 230 on the ultrasound image is that when the display of the active cursor is linked with the ninth operation according to the ninth instruction, a vertical line 242 from the interface operation position where the active cursor 230 is located to the third straight line 202 is drawn, and when the movement position of the active cursor 230 is changed, the vertical line is changed accordingly.

As shown in fig. 10(C), the display of the active cursor 230 is interlocked with the ninth operation until the active cursor moves to the target position BN, at which time a tenth instruction generated when the tenth operation is input using the human machine interaction device is received, and the tenth operation may be the same as the input of the aforementioned second operation, and thus the tenth instruction may also be the same as the aforementioned second instruction, for example, the tenth instruction is obtained by the input of a key. And extracting the corresponding interface operation position according to the tenth instruction, and recording the interface operation position associated with the tenth instruction, which indicates that the user determines that the measurement target position BN needs to be marked on the ultrasonic image through the operation. After recording, a position mark 232 may be marked at the position BN, the position mark based on the tenth instruction being located at the interface operation position associated with the tenth instruction. The moving trackball is then used to move the active cursor 230 to position BL, during which the display of the position marker 232 remains at the marked position BN, while the vertical line 242 between the position marker 232 and the third straight line 202 is displayed. When the movable cursor 230 is moved to the position BL by using the moving trackball, a vertical line 242 from the interface operation position where the movable cursor is located at the current time to the third straight line 202 is synchronously drawn. If the position BL is determined to need to be measured and recorded, recording an interface operation position associated with a tenth instruction according to the tenth instruction input by the tenth operation, indicating that the user determines that the measurement target position BL needs to be marked on the ultrasonic image through the operation.

As shown in fig. 10(D), the display of the active cursor 230 is interlocked with the ninth operation according to the ninth command until the active cursor moves to the target position UT. The display of the position mark 232 is retained at the position BN already marked in the process, while the vertical line 242 between the position mark 232 and the third straight line 202 is displayed. It is also possible to draw a position mark 232 at the position BL for displaying the target position that has been marked, while displaying a vertical line 242 between the position mark 232 and the third straight line 202. In the process of linking the display of the active cursor 230 with the ninth operation according to the ninth instruction, the vertical line 243 from the interface operation position where the active marker 230 is located to the third straight line 202 at the present time can be automatically drawn in the process of moving the active marker 230 to the position UT.

In the process, each time a position mark is carried out, the measurement of one measurement item is represented, so that the marking can be directly carried out by moving the movable cursor according to the ninth instruction and recording the moving position according to the tenth instruction when the measurement of the next measurement item is carried out, and the cyclic measurement operation of the next measurement item can be switched by key input. When all the measurement items are operated, the measurement end input can be performed by double-click or other key operation. When the movable cursor moves at any position on two sides of the third straight line, vertical lines (242, 242 and 243) from the interface operation position where the movable cursor is located at the current moment to the third straight line are drawn all the time, so that a user can more clearly know that the reference-based vertical measurement reference needed in the measurement process appears. Further, in one embodiment, after the interface operation position associated with the tenth instruction is recorded, vertical lines (242 ) between the position mark and the third straight line are displayed.

In the activated current image display window, the display of the third straight line is linked with the eleventh operation, or the display of the active cursor is linked with the ninth operation, and the manner of activation can be referred to the related description, and will not be described herein. This avoids interference between the ultrasound image operations in the two-screen display mode. As can be seen in the embodiment shown in fig. 10, the marking of the at least one target position can be effected continuously by means of active markings. In the process from step 140 to step 180, the image processing module receives a ninth instruction generated when a ninth operation is input by using the human-computer interaction device, causes the display of the movable cursor to be linked with the ninth operation according to the ninth instruction, receives at least one tenth instruction generated when at least one tenth operation is input by using the human-computer interaction device, extracts a corresponding interface operation position according to the tenth instruction, and records at least one interface operation position associated with the tenth instruction, so that the cooperative marking of a plurality of continuous target positions can be realized. Furthermore, the ninth operation in this embodiment may be a continuous input, and therefore in one embodiment, the image processing module receives a ninth instruction generated when the ninth operation is continuously input by using the human-computer interaction device, and causes the continuous display of the movable cursor to be linked with the ninth operation according to the ninth instruction.
