3D ultrasound is a medical ultrasound technique, often used during pregnancy, providing three dimensional images of the fetus. Often these images are captured rapidly and animated to produce a “4D ultrasound”.
Clinical use of this technology is an area of intense research activity especially in fetal anomaly scanning but there are also popular uses that have been shown to improve fetal-maternal bonding. 4D baby scans are similar to 3D scans except that they show fetal movement as shown in the video clip.
