Like regular ultrasounds, 3D and 4D ultrasounds use sound waves to create an image of your baby in your womb.

3D/4D Ultrasound is a safe and widely used imaging technique. Ultrasound produces detailed images of the body in real-time using high-frequency sound waves which are produced by a special ultrasound probe.  (Sonography) Ultrasound has no known harmful effects and can be used to image a variety of conditions including pregnancy, gallstones, and varicose veins.

3D Ultrasonography: 3D ultrasound is a medical ultrasound technique, often used in fetal, cardiac, trans-rectal, and intra-vascular applications. 3D ultrasound refers specifically to the volume rendering of ultrasound data and is also referred to as 4D (3-spatial dimensions plus 1-time dimension) when it involves a series of 3D volumes collected over time

4D Ultrasonography: 4D scans show moving 3D images of your baby, with time being the fourth dimension It’s natural to be excited by the prospect of your first scan.
