Embodiment
[0051] This embodiment discloses a method for automatically measuring the angle of descent of the fetal head based on the segmentation of the pubic symphysis and the contour segmentation of the fetal head based on ultrasonic images, such as figure 1 As shown, it mainly includes the following steps:
[0052] S1. Collect transperineal ultrasound images of pregnant women and record them as original images. The method of transperineal ultrasound image acquisition is to make the pregnant woman's legs and hips at a 45-degree angle, and her legs and knees at a 90-degree angle, lie on the bed in a semi-recumbent position, use a curved ultrasonic probe, and use a sagittal plane The form of the pubic symphysis is placed below the pubic symphysis, and the probe is moved slightly until the anatomy of the pubic symphysis and the contour of the fetal head can be clearly observed on the ultrasound image. A total of 88 ultrasound images were collected, and the size of each image was 1024*768...
