High-frequency sound waves could capture an image of fetus by an obstetric ultrasound mechanism. And obstetricians usually ask to check on the fetus’s health at regular intervals throughout pregnancy.
As said by the Radiological Society of North America, an ultrasound may be used to verify:
• The presence and age of an embryo/fetus.
• Any congenital abnormalities.
• The location and position of the fetus and placenta.
• Multiple pregnancies.
• The amount of amniotic fluid that surrounds the fetus.
• Any abnormalities in the cervix or womb.
