An embodiment of the present application will be described in further detail below on the basis of the foregoing embodiment shown in fig. 2. Referring to fig. 3, another embodiment of the amniotic fluid index measurement method according to the embodiment of the present application includes:

301. Acquiring ultrasonic images of four different quadrants of the uterus of a testee, wherein the ultrasonic images of the four different quadrants comprise a first ultrasonic image, a second ultrasonic image, a third ultrasonic image and a fourth ultrasonic image which are sequentially scanned according to an ultrasonic scanning sequence, and the first ultrasonic image, the second ultrasonic image, the third ultrasonic image and the fourth ultrasonic image respectively correspond to the four different quadrants of the uterus of the testee;

In this embodiment, the four different quadrants are respectively located in the upper left position, the upper right position, the lower right position, and the lower left position in the uterus of the subject, wherein the quadrant in the upper left position is closer to the right hand of the subject than the quadrant in the upper right position, and the quadrant in the lower left position is closer to the head of the subject than the quadrant in the upper left position; the quadrant in the upper right position is farther from the subject's right hand than the quadrant in the upper left position, and the quadrant in the lower right position is closer to the subject's head; a quadrant in the lower right position, the quadrant relative to the lower left position being farther from the subject's right hand, and the quadrant relative to the upper right position being farther from the subject's head; the lower left quadrant is closer to the subject's right hand relative to the lower right quadrant, and the upper left quadrant is farther from the subject's head.

For example, as shown in fig. 4, four different quadrants of the subject's uterus may be divided into a quadrant Q1 near the subject's right hand and near the subject's head, a quadrant Q2 far the subject's right hand and near the subject's head, a quadrant Q3 far the subject's right hand and far the subject's head, and a quadrant Q4 near the subject's right hand and far the subject's head.

When each quadrant is scanned in an ultrasonic scanning sequence, each quadrant can be scanned in a clockwise direction in turn, for example, under the scanning operation of a user holding an ultrasonic probe to the uterus of a testee, the first ultrasonic scanning operation of the user is responded, and the quadrant at the upper left position is scanned in an ultrasonic manner to obtain a first ultrasonic image; then, responding to a second ultrasonic scanning operation of the user, and performing ultrasonic scanning on the quadrant at the upper right position to obtain a second ultrasonic image; then, responding to a third ultrasonic scanning operation of the user, and performing ultrasonic scanning on the quadrant at the lower right position to obtain a third ultrasonic image; and finally, responding to a fourth ultrasonic scanning operation of the user, and performing ultrasonic scanning on the quadrant at the lower left position to obtain a fourth ultrasonic image. The four ultrasound images may be displayed in different windows in the display screen for review by the physician, respectively.

For example, as shown in fig. 4, the scanning is performed in the clockwise direction as described above, and the ultrasound image of the quadrant Q1 (i.e., the first ultrasound image), the ultrasound image of the quadrant Q2 (i.e., the second ultrasound image), the ultrasound image of the quadrant Q3 (i.e., the third ultrasound image), and the ultrasound image of the quadrant Q4 (i.e., the fourth ultrasound image) may be sequentially obtained.

The above-described clockwise scanning is started from the quadrant at the upper left position, but of course, the clockwise ultrasonic scanning may be started from the quadrant at another position, for example, the upper right quadrant, the lower left quadrant, and the upper left quadrant may be scanned in this order. The present embodiment does not limit the quadrant from which the clockwise scan starts.

Besides the clockwise scanning, the scanning can be performed in other directions. For example, a user may begin scanning the quadrant of the upper left position, then the quadrant of the upper right position, then the quadrant of the lower left position, and finally the quadrant of the lower right position with the ultrasound probe held by the user. Therefore, the ultrasonic imaging device responds to each scanning operation of the user, and sequentially carries out ultrasonic scanning on each quadrant, for example, responds to a first ultrasonic scanning operation, and carries out ultrasonic scanning on the quadrant at the upper left position to obtain the first ultrasonic image; responding to a second ultrasonic scanning operation, and performing ultrasonic scanning on the quadrant at the upper right position to obtain a second ultrasonic image; responding to a third ultrasonic scanning operation, and performing ultrasonic scanning on the quadrant at the lower left position to obtain a third ultrasonic image; and responding to the fourth ultrasonic scanning operation, and performing ultrasonic scanning on the quadrant at the lower right position to obtain the fourth ultrasonic image.

For example, as shown in fig. 4, the scanning is performed in the ultrasonic scanning order, and an ultrasonic image of quadrant Q1 (i.e., a first ultrasonic image), an ultrasonic image of quadrant Q2 (i.e., a second ultrasonic image), an ultrasonic image of quadrant Q4 (i.e., a third ultrasonic image), and an ultrasonic image of quadrant Q3 (i.e., a fourth ultrasonic image) may be sequentially obtained.

In addition, the user may first scan the quadrant of the lower left position, then the quadrant of the upper left position, then the quadrant of the lower right position, and finally the quadrant of the upper right position. Therefore, the ultrasonic imaging device responds to each scanning operation of the user, and sequentially carries out ultrasonic scanning on each quadrant, for example, responds to a first ultrasonic scanning operation, and carries out ultrasonic scanning on the quadrant at the lower left position to obtain the first ultrasonic image; responding to a second ultrasonic scanning operation, and performing ultrasonic scanning on the quadrant at the upper left position to obtain a second ultrasonic image; responding to a third ultrasonic scanning operation, and performing ultrasonic scanning on the quadrant at the lower right position to obtain a third ultrasonic image; and responding to the fourth ultrasonic scanning operation, and performing ultrasonic scanning on the quadrant at the upper right position to obtain the fourth ultrasonic image.

For example, as shown in fig. 4, the scanning is performed in the ultrasonic scanning order, and an ultrasonic image of quadrant Q4 (i.e., a first ultrasonic image), an ultrasonic image of quadrant Q1 (i.e., a second ultrasonic image), an ultrasonic image of quadrant Q3 (i.e., a third ultrasonic image), and an ultrasonic image of quadrant Q2 (i.e., a fourth ultrasonic image) may be sequentially obtained.

302. Responding to a first measurement operation, determining a first measurement position on the first ultrasonic image according to the ultrasonic scanning sequence, and determining the distance of the first measurement position to obtain a first measurement result;

303. Responding to a second measurement operation, determining a second measurement position on the second ultrasonic image according to the ultrasonic scanning sequence, and determining the distance of the second measurement position to obtain a second measurement result;

304. Responding to a third measurement operation, determining a third measurement position on the third ultrasonic image according to the ultrasonic scanning sequence, and determining the distance of the third measurement position to obtain a third measurement result;

305. responding to a fourth measurement operation, determining a fourth measurement position on the fourth ultrasonic image according to the ultrasonic scanning sequence, and determining the distance of the fourth measurement position to obtain a fourth measurement result;

In a preferred implementation manner of this embodiment, the ultrasound imaging apparatus may be connected to a display screen, where the display screen includes four windows, and the ultrasound image of any quadrant of the four different quadrants is displayed in a target window of the display screen, where the target window is a window corresponding to the any quadrant of the four windows.

For example, as shown in fig. 5, 4 windows may be divided on the display screen, each window displays 1 quadrant of the ultrasound image, where the window in the upper left corner displays the ultrasound image in the quadrant in the upper left position, the window in the upper right corner displays the ultrasound image in the quadrant in the upper right position, the window in the lower right corner displays the ultrasound image in the quadrant in the lower right position, and the window in the lower left corner displays the ultrasound image in the quadrant in the lower left position, and each illustrated ultrasound image is obtained by scanning four quadrants in turn in the clockwise direction, that is, in response to the first ultrasound scanning operation of the user, the quadrant in the upper left position is first subjected to ultrasound scanning to obtain the first ultrasound image; then, responding to a second ultrasonic scanning operation of the user, and performing ultrasonic scanning on the quadrant at the upper right position to obtain a second ultrasonic image; then, responding to a third ultrasonic scanning operation of the user, and performing ultrasonic scanning on the quadrant at the lower right position to obtain a third ultrasonic image; and finally, responding to a fourth ultrasonic scanning operation of the user, and performing ultrasonic scanning on the quadrant at the lower left position to obtain a fourth ultrasonic image. Further, the first ultrasound image, the second ultrasound image, the third ultrasound image, and the fourth ultrasound image may be sequentially measured in the same order as the ultrasound scanning order.

Wherein, the measuring position of the ultrasonic image of each quadrant can be the connecting line between the measuring points, and the distance of the measuring position can be the length of the connecting line between the measuring points. For example, in the measurement process, two measurement points may be determined, as shown in the figure, two points are determined in the first ultrasound image and the distance L1 between the two points is calculated as the measurement result of the first ultrasound image, and the other quadrants similarly determine the two points and calculate the distance between the two points, so as to obtain the measurement result L2 of the second ultrasound image, the measurement result L3 of the third ultrasound image, and the measurement result L4 of the fourth ultrasound image.

The method for determining the measuring position by using the ultrasonic images of each quadrant can be that the measuring position in the ultrasonic image is identified according to an image identification algorithm, and the ultrasonic image is any one of the ultrasonic images of four different quadrants of the uterus of a testee; receiving a determination operation of a user on a measurement position of the ultrasonic image, and determining the measurement position of the ultrasonic image according to the determination operation; or may be that a measurement position in the ultrasound image is identified according to an image recognition algorithm, and when a user's modification operation of the measurement position is received, a new measurement position is determined according to the modification operation.

The image recognition algorithm may be a pattern recognition algorithm, a machine learning algorithm, or the like, and specifically a machine learning model may be trained using a large number of ultrasound image samples according to the machine learning algorithm, such that the machine learning model is able to determine measurement points in the ultrasound image and the area traversed by the line between the measurement points does not contain any anatomy and umbilical cord of the fetus. The measurement point determination operation input by the user may be that the user moves the trackball to click on the ultrasound image to select the measurement point. Likewise, the modification to the measurement point may be the user moving the trackball to click on the selected measurement point on the ultrasound image.

In this embodiment, in addition to sequentially measuring the ultrasound images of four different quadrants in the ultrasound scanning order, the user may also change the measurement order halfway. For example, when the first ultrasound image is measured, if a measurement instruction for the third ultrasound image input by a user is received, after the measurement of the first ultrasound image is completed, the third ultrasound image is measured, and after the measurement of the third ultrasound image is completed, the second ultrasound image and the fourth ultrasound image are sequentially measured in the ultrasound scanning order. Or when the second ultrasonic image is measured, if a measurement instruction of the fourth ultrasonic image input by a user is received, after the measurement of the second ultrasonic image is completed, the fourth ultrasonic image is measured, and after the measurement of the fourth ultrasonic image is completed, the measurement of the third ultrasonic image is continued.

306. Thawing a current ultrasonic image of a target quadrant in response to thawing operation of a user on the ultrasonic image of the target quadrant, and performing ultrasonic scanning on the target quadrant based on ultrasonic scanning operation of the user on the target quadrant to obtain a new target ultrasonic image of the target quadrant;

In this embodiment, if the user is not satisfied with the ultrasound image of a certain quadrant, for example, the area of the fetal limb and the umbilical cord displayed by the ultrasound image is large, so that the amniotic fluid depth measurement is affected, the user can instruct the ultrasound imaging device to recheck the quadrant. Specifically, the user inputs a defrosting operation on an ultrasonic image of a target quadrant, wherein the target quadrant is any one of four different quadrants of the uterus of the testee, then the ultrasonic imaging device unfreezes the current ultrasonic image of the target quadrant, and the ultrasonic image of the target quadrant is acquired again under the ultrasonic scanning operation of the user on the target quadrant, so that a new target ultrasonic image of the target quadrant is obtained.

307. Sequentially determining measurement positions and distances among measurement positions of quadrants which are not measured in the four different quadrants according to the ultrasonic scanning sequence to obtain measurement results of the quadrants which are not measured, wherein the measurement results of the quadrants which are not measured comprise the measurement results of the target ultrasonic image;

After the re-acquisition of the ultrasonic image of the target quadrant is completed, the quadrants which are not measured in the four quadrants can be continuously and sequentially measured according to the ultrasonic scanning sequence, and the measurement results of the quadrants which are not measured in the four quadrants are obtained. Wherein the measurement results of the quadrants of the incomplete measurement comprise measurement results of the target ultrasound image.

For example, when measuring the second ultrasonic image, the user re-collects the ultrasonic image for the quadrant corresponding to the original third ultrasonic image to obtain a new third ultrasonic image, and after completing the measurement of the second ultrasonic image, the new third ultrasonic image and the fourth ultrasonic image are measured sequentially according to the ultrasonic scanning sequence.

After obtaining the measurement result of the target ultrasonic image, the amniotic fluid index of the uterus of the subject may be determined according to the measurement result of the target ultrasonic image, and the measurement result of the ultrasonic images of the other quadrants of the four quadrants except for the target quadrant.

Along with the above example, after the measurement result of the new third ultrasonic image and the measurement result of the fourth ultrasonic image are obtained, the amniotic fluid index of the uterus of the subject is calculated from the measurement result of the new third ultrasonic image, the measurement result of the first ultrasonic image, the measurement result of the second ultrasonic image, and the measurement result of the fourth ultrasonic image.

In a preferred implementation manner of this embodiment, the ultrasound imaging apparatus may be connected to a display screen, where the display screen includes four windows, and the ultrasound image of any quadrant of the four quadrants is displayed in a target window of the display screen, where the target window is a window corresponding to the any quadrant of the four windows. As shown in fig. 5, 4 windows may be divided on the display screen, each window displaying 1 quadrant of the ultrasound image, wherein the window in the upper left corner displays the ultrasound image of the quadrant in the upper left position, the window in the upper right corner displays the ultrasound image of the quadrant in the upper right position, the window in the lower right corner displays the ultrasound image of the quadrant in the lower right position, and the window in the lower left corner displays the ultrasound image of the quadrant in the lower left position.

After the measurement results of any quadrant are obtained, the preset position of the display screen in the target window can be controlled, and the measurement results of any quadrant are displayed, for example, the measurement results are displayed at the right lower corner position of the target window. In addition, the display screen may be controlled to display the measurement result of any quadrant in a preset area outside the target window on the display screen, for example, the measurement result is displayed in a blank area outside the 4 windows shown in fig. 5, and the measurement result is marked as the measurement result of any quadrant.

For example, quadrant Q1 shown in fig. 4, whose ultrasound image may be displayed in the upper left window shown in fig. 5, and whose measurement results may be displayed in the lower right position in the upper left window shown in fig. 5. Similarly, ultrasound images and measurements of other quadrants may be displayed on the display screen in a similar fashion.

In another preferred implementation of this embodiment, when the measurement operation is performed for any quadrant, the display screen may be controlled to display a measurement cursor on the target window to indicate that measurement is currently being performed for any quadrant. And after the measurement is completed in any quadrant, determining the next quadrant of the any quadrant in the ultrasonic scanning sequence, and controlling a display screen to jump to a window corresponding to the next quadrant so as to display a measurement cursor to prompt the measurement of the next quadrant after the measurement is completed in any quadrant.

Taking fig. 4 as an example, when the measurement in the quadrant Q1 is performed, a measurement cursor is displayed in a window corresponding to the quadrant Q1 (an upper left corner window as shown in fig. 5) to prompt that the measurement is currently being performed on the ultrasound image in the quadrant Q1. After the measurement of the quadrant Q1 is completed, if the ultrasonic scanning sequence is clockwise, determining the next quadrant to be measured as the quadrant Q2, and further jumping to a window corresponding to the quadrant Q2 (an upper right corner window as shown in fig. 5) and displaying a measurement cursor to prompt that the ultrasonic image of the quadrant Q2 is about to be measured. Similarly, the measurement cursor can be displayed in a jumping manner when the measurement is performed in the subsequent quadrant, so as to prompt the measurement progress to the user.
