Step 83: and screening the ultrasonic images.
In some embodiments, monitoring of labor progression and clinical assessment of labor patterns is performed primarily by two-dimensional ultrasound images, which operate as follows: let pregnant and lying-in woman's both legs and buttock be 45 degrees angles, both legs and knee are 90 degrees angles, lie in the bed in half-lying position posture, and the ultrasonic probe uses curved ultrasonic probe, places under the pubic symphysis in sagittal form, slightly moves the probe, until can clearly observe pubic symphysis anatomy structure and child head profile anatomy structure on the ultrasonic image. Because of the factors such as the imaging technique of the operator, the difference of the ultrasonic images is caused, so that the ultrasonic images need to be screened to screen out the optimal ultrasonic images.
For example, the filtering can be performed according to the definition of the ultrasonic image, the ultrasonic image with the definition meeting the threshold value is reserved, and the ultrasonic image with the definition not meeting the threshold value is deleted.
For another example, the filtering can be performed according to the characteristic information in the ultrasonic image, and the ultrasonic image with the characteristic information meeting the preset requirement is reserved.
In some embodiments, edge detection may be performed on the ultrasound image. For example, the ultrasonic image may be subjected to edge detection by using a sobel edge detection method, laplace edge detection or Canny edge detection, so as to obtain contour information of a corresponding object in the ultrasonic image. Such as fetal head contours, pubic symphysis contours, etc. in ultrasound images. And then determining the edge area according to the edge detection result.
After the edge detection result is obtained, the edge area can be determined according to the determined edge contour. For example, the footprint of the fetal head contour and the footprint of the pubic symphysis contour in the acoustic image may be determined. And screening the ultrasonic images according to the edge areas. If, for example, the edge area is greater than or equal to the area threshold, the ultrasound image is preserved. And if the edge area is smaller than the set area threshold, removing the ultrasonic image.
Further, the screening may be performed in combination with the footprint of the fetal head contour and the pubic symphysis contour, e.g., if the footprint of the fetal head contour and the footprint of the pubic symphysis contour are both greater than or equal to an area threshold, then the ultrasound image is retained. And if one of the areas is smaller than the set area threshold, removing the ultrasonic image.
Step 84: and determining the fetal head orientation from the screened ultrasonic images.
Step 85: displaying the fetal head orientation.
In the embodiment, the ultrasonic images are screened, and the fetal head orientation is determined by using the screened ultrasonic images, so that the accuracy of the determined fetal head orientation can be improved; and the fetal head direction is displayed, so that the medical staff can more accurately assist the midwife and make the state of the fetus clear based on the displayed fetal head direction, the midwife efficiency is improved, and the production risk is reduced.
In an application scenario, the following is described with reference to fig. 9 to 10:
step 91: a transperineal ultrasound image dataset is obtained.
Step 92: and screening the ultrasonic images in the ultrasonic image data set.

Step 93: and carrying out data amplification on the screened ultrasonic images by using data enhancement.
Step 94: the ultrasound image is preprocessed.
Step 95: the preprocessed ultrasound image is input to the image segmentation model.
Step 96: and extracting the outline characteristics of the brain midline of the ultrasonic image by using the image segmentation model.
Step 97: the midline angle of the brain is calculated from the midline contours of the brain.
The midline angle of the brain is the angle formed by the midline of the brain and the pelvic axis. The fetal head direction combined with MLA < 45 degrees or AOP > 120 degrees is an ultrasonic index for predicting success of vacuum suction midwifery delivery of the occipital fetus.
Step 98: and displaying the angle of the midline of the brain on a display interface.
As shown in fig. 10, the calculated central line angle of brain (MLA) parameters are displayed, and the display contents include: the parameter diagram of the cross section and the calculation result of the parameter are adopted, meanwhile, the middle line of the brain faces the occipital part to be used as a pointer, and the screen is used as a clock to dynamically represent the position of the fetal head azimuth. As shown in fig. 10, the current midline angle of the brain is 81 degrees. Wherein OA (Occiput Anterior) in FIG. 10 represents the region of the front of the pillow in a specific range of > 9.30h and < 2.30h, LOT (Left; occiput Transverse Position) represents the Left lateral of the pillow in a specific range of > 2.30h and < 3.30h, OP (Occiput Posterior) represents the rear of the pillow in a specific range of > 3.30h and < 8.30h, ROT (Right; occiput Transverse Position) represents the Right lateral of the pillow in a specific range of > 8.30h and < 9.30 h. Then it can be mapped to the OP region.
In this embodiment, through the above-mentioned mode, can confirm child head position based on the ultrasonic image, the medical personnel of being convenient for carry out more accurate midwifery and clear fetal state based on child head position, promote midwifery efficiency, reduce the production risk. Compared with a vaginal finger examination method, on one hand, the change of fetal head orientation is detected by an ultrasonic device, so that the evaluation of the labor progress is more accurate; on the other hand, the angle of the central line of the brain is intuitively displayed, so that the progress of the labor is visualized, a doctor is helped to acquire the current fetal head azimuth information more intuitively, the diagnosis of the labor stagnation and the intervention of the labor are more accurate, the doctor is helped to make a decision more scientifically in the labor, and the labor risk is reduced.
