Embodiment

[0031] refer to figure 1 As shown, the present embodiment provides a method for measuring and calculating fetal head descent, which is characterized in that it includes the following steps:

[0032] (A1) Ultrasound images showing the upper edge of the pubic symphysis, the lower edge of the pubic symphysis, and the contour of the fetal head were acquired at two time points;

[0033] (A2) Using the upper edge of the pubic symphysis and the lower edge of the pubic symphysis as matching feature points, registering the ultrasonic images at the two preset time points;

[0034] (A3) Calculate the displacement of the tire head contour at the two preset time points before and after the registration, which is the descending range of the tire head between the two time points.

[0035] It should be noted that the fetal head descent refers to the distance the fetal head descends along the birth canal within a period of time. At present, manual digital inspection is used in clinical practi...

Abstract

The invention provides a fetal head descending measuring and calculating method. The method is characterized by comprising the following steps of collecting ultrasonic images showing the superior margin of pubic symphysis, the inferior margin of pubic symphysis and the fetal head profile respectively at two time points; conducting registration on the ultrasonic images at the two preset time pointswith the superior margin of pubic symphysis and the inferior margin of pubic symphysis as matching feature points; calculating the displacement amount of the fetal head profile at the two preset timepoints after registration, namely the fetal head descending amplitude between the two time points, and preferentially, the two time points are the two time points respectively at the beginning and ending of a uterine contraction period. By means of the fetal head position measuring and calculating method and device, the fetal head position can be more conveniently and objectively measured and calculated, thus more precise data is provided for doctors, and then the doctors are helped to make more accurate comprehensive judgment; the fetal head descending amplitude within one uterine contraction period can be calculated, and thus the effectiveness of one-time uterine contraction is judged.

Description

technical field [0001] The invention relates to the field of obstetrical monitoring, in particular to a method and device for measuring and calculating fetal head descent. 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 ...
