  • Patent number: 11744541
    Abstract: A method for measuring parameters in an ultrasonic image, includes: obtaining a pelvic ultrasound image, wherein the pelvic ultrasound image is acquired by receiving ultrasound echoes from a pelvic floor tissue with an ultrasound probe and contains an area representing the pelvic floor tissue; displaying the pelvic ultrasound image; determining a position of an inferoposterior margin of symphysis pubis in the pelvic ultrasound image; determining a central axis of symphysis pubis in the pelvic ultrasound image; determining an axis that passes through the determined position of the inferoposterior margin of symphysis pubis and is at an angle of 135 degree with respect to the determined central axis of symphysis pubis; determining a position of a bladder neck in the pelvic ultrasound image; and calculating a distance from the determined position of the bladder neck to the determined axis to obtain a value of a bladder neck-symphyseal distance.
