Foetal ultrasound. 3-D ultrasound scan of the face and forearm of a healthy human foetus. This foetus is estimated to be around 31 weeks old,which is midway through the third trimester (last three months) of pregnancy. 3-D scanning enables physiological disorders such as harelip and spina bifida to be diagnosed before birth. If detected,it may be possible to perform corrective surgery while the foetus is still in the uterus. 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 | |
