Foetus. Coloured 3-D ultrasound scan of an eight- week-old foetus in the uterus. A developing embryo is first called a foetus after eight weeks. At this time,the foetus measures about 2.5 centimetres in length. All of the bodily organs have developed and fingers and toes are appearing on the paddle-like limbs. Ultrasound scanning is a diagnostic technique that 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. Foetal ultrasound scanning is routine during pregnancy. 3-D scanning uses computer technology to return more detailed images than conventional 2-D scans | |
