3D pertains to the third dimension which is depth.

3D ultrasound scans provide an advanced imaging technique that offers a three-dimensional view of the foetus, enhancing the traditional 2D ultrasound experience. Unlike 2D scans, which produce flat, cross-sectional images, 3D ultrasounds create detailed, lifelike images by combining multiple 2D pictures taken from various angles. This allows for a more comprehensive and realistic depiction of the baby’s features, including facial expressions and foetal movements.

The technology behind 3D ultrasounds involves capturing sound waves that bounce off the foetus and surrounding tissues, then processing these reflections to construct a three-dimensional image using the latest computer technology.  For expectant parents, 3D ultrasounds allow for a deeper emotional connection to the pregnancy.
