Parameter description:

(1) Biparietal diameter (BPD)
The biparietal diameter is not the circumference of the head, but the length of the parietal diameter on both sides of the bone, approximately close to the temples; the abdominal circumference should be measured on the same plane as the fetal liver and stomach; and the shape of the thigh bone when viewed on ultrasound is Like the bones that puppies love to eat, expectant mothers can carefully observe them through the ultrasound display.
(2)Head circumference (HC)
(2)Abdominal circumference (AC)
Some doctors will also measure the mother's abdominal circumference: measure the highest part of the abdomen in a transverse manner. However, because each expectant mother's abdominal circumference varies greatly, it is more recommended that expectant mothers can measure themselves regularly at home.
(3) Femoral length (FL)
The expectant mother lies on her back and the doctor uses a measuring tape to measure the length from the fundus of the expectant mother's uterus (near the position below the expectant mother's sternum) to the upper edge of the pubic symphysis to estimate the growth of the fetus. At weeks and above, the number of weeks of gestation is usually equivalent to this distance.
