Last Updated on March 23, An ultrasound scan sends high-frequency sound waves to the uterus during pregnancy to capture the image of the foetus. Images in ultrasound scans reveal the developmental phases of the body, often revealing bones and tissues through shades of white and grey. An ultrasound scan is used to get a sneak peek of your baby and analyse how the foetus is faring inside the womb. However, the gender of the baby is not revealed through an ultrasound scan in India, as it is considered illegal. Nowadays, 4D and 3D colour scans are popular ultrasound choices during pregnancy for revealing high-quality images of babies.
