Ultrasound is basically a method that uses sound waves to study the internal parts of the body and in the case of a pregnant women, her womb to check the fetus. High-frequency sound waves of about 20,000 Hz and above, which are past the range of normal hearing are beamed to the area that needs to be studied and the returning echoes are recorded there by. Pregnancy Ultrasound is an important step that the expectant mother needs to go through, to ensure the safety of the baby in the womb.
