Embodiment

[0033] This embodiment provides a method for generating a labor navigation curve, which is characterized in that it includes the following steps:

[0034] (A1) Obtain the coordinates of the upper edge of the pubic symphysis and the lower edge of the pubic symphysis on the ultrasound image;

[0035] (A2) Calculate the coordinates of the guide point on the ultrasound image in sequence according to the predicted constraint relationship;

[0036] (A3) Connecting the guide points sequentially on the ultrasound scanning plane to generate a labor process navigation curve.

[0037] As a preferred embodiment of the present invention, the predictive constraint relationship is: the three interior angles of the triangle formed by the upper edge of the pubic symphysis, the lower edge of the pubic symphysis and any one of the guide points on the ultrasonic scanning plane are predictable;

[0038] According to the predicted constraint relationship, the step of calculating the coordinates of...

Abstract

The invention discloses a parturition navigation curve generation method. The method comprises the following steps that coordinates of the upper margin and lower margin of the pubic symphysis on an ultrasound image are obtained; according to a predictive constraint relationship, coordinates of guiding points on the ultrasound image are calculated in sequence; the guiding points on an ultrasonic scanning plane are connected in sequence to generate a parturition navigation curve. The invention discloses a fetal head position calculating method. The method comprises the following steps that the parturition navigation curve is generated on the ultrasound image; scale values of the guiding points are distributed in sequence; in the ultrasound image, the scale corresponding to the intersection point of the outline of the fetal head and a delivery guiding curve is the position of the fetal head. The invention also provides a fetal head position calculating device. The device is characterizedby comprising an ultrasonic imaging acquiring module, a feature point marking module and a data processing module. The fetal head position calculating method and device can more conveniently and objectively calculate the position of the fetal head and provide a basis for clinical decision-making.

Description

technical field [0001] The invention relates to the field of obstetrical monitoring, in particular to a method for measuring and calculating the fetal head position. Background technique [0002] In obstetrics, the size and dynamic spatial relationship between the fetal head and the pelvis (referred to as "head-pelvic relationship") is crucial to the choice and management of delivery methods; obstetrics clinical needs to monitor these data accurately at any time to help doctors and midwives carry out scientific research. childbirth decision. [0003] It is very important to understand the posture of the fetus in the womb, because it is related to the choice of delivery method. Because the fetus is soaked in amniotic fluid, and the fetal head is the heaviest part of the body, the fetal head is generally downward, that is, the head position, which accounts for about 95% of the total number of deliveries. Others such as buttocks first (breech), feet or legs first, arms first ...
