This invention discloses an automatic identification method for pelvic organ prolapse based on deep learning and the PCL line, comprising: S1: acquiring and preprocessing medical images of the pelvic floor region, and simultaneously annotating the bladder, uterus, rectum, and bony anatomical structures to construct a training dataset; S2: constructing and training a multi-objective deep learning segmentation model based on the training data to achieve automatic segmentation of the bladder, uterus, rectum, pubic symphysis, and the two vertebrae from the coccyx; S3: extracting the lowest edge point of the segmented pubic symphysis region and the highest edge point of the two vertebrae from the coccyx region to construct a set of bony key points; S4: connecting the bony key points to automatically generate the pelvic floor reference line (PCL line); S5: analyzing the spatial positional relationship of the bladder, uterus, and rectum relative to the PCL line to obtain the downward displacement feature information of the pelvic organs; S6: automatically determining the degree of pelvic organ prolapse based on the spatial positional relationship. This invention achieves automated identification of the degree of pelvic organ prolapse, reduces subjective errors caused by manual measurement, and improves the consistency, accuracy, and efficiency of the assessment.

The application relates to the technical field of ultrasound images, and discloses an acquisition method of an ultrasound image during childbirth, an ultrasound imaging device and a readable storage medium. The method comprises the following steps: emitting an ultrasound signal to target tissue, collecting an ultrasound echo signal reflected by the target tissue, forming an ultrasound image corresponding to the target tissue based on the ultrasound echo signal, screening the ultrasound image to screen out a target ultrasound image meeting preset requirements, and displaying the target ultrasound image, wherein the target ultrasound image contains a tissue region of a pubic symphysis and a fetal head contour. In the manner, the accuracy of the ultrasound image can be improved, the dependence on the professionalism of medical staff is reduced, and the method is suitable for more operation scenes.

This invention discloses a method for collaborative registration and alignment of multi-target curve medical images of the female pelvic floor, comprising: S1: marking the target curve, SCIPP line, and segmentation markers in each sample data; S2: using a dimensionality reduction method combining Y-Z plane projection and X-coordinate dynamic compensation to reduce the dimensionality of the three-dimensional medical data to two dimensions; S3: smoothing the curves using cubic spline interpolation before registration to avoid the influence of noise in the original data on the registration accuracy; S4: calculating the translation matrix based on the reference point of the SCIPP line at the lower edge of the pubic symphysis, and aligning the lower edge of the first reference point at the lower edge of the pubic symphysis. S5: Move to the origin; S6: Use the SCIPP line as a reference vector and calculate the rotation matrix using the difference between the reference vector and the target angle; S7: Apply the corresponding translation and rotation matrices to the corresponding sample curve data to establish a unified coordinate system; S8: Calculate the average value of the curve segment based on the marker points, and then combine the average values ​​calculated segment by segment into the average value of the entire curve; S9: Calculate the centroid, local centroid, and global centroid of each curve, and translate the centroid of the corresponding curve to coincide with the local and global centroids of the corresponding curve to achieve alignment. This invention realizes the standardized registration, two-dimensional alignment, and anatomical segmented averaging analysis of female pelvic organ contour curve data, providing accurate quantitative basis for the diagnosis and clinical research of urological diseases.
