Foetal ultrasound. Three-dimensional (3-D) ultrasound scan of a human foetus. Its head is at centre right,its body at bottom centre,and its legs at far left. The umbilical cord is seen at centre left. The image was produced by a third generation 3-D ultrasound scanner called Voluson 730. 3-D scanning enables physiological disorders such as harelip and spina bifida to be diagnosed before birth. Ultrasound is a diagnostic technique which sends high-frequency sound waves into the body via a transducer. The returning echoes are recorded and used to build an image of an internal structure | |
