MODEL RELEASED. Ultrasound scan. Pregnant woman having an ultrasound scan,performed by a health worker. Ultrasound is a diagnostic technique in which very high frequency sound waves are passed into the body through a transducer (centre left,on abdomen). The reflected echoes are detected and used to build an image (upper right) of the foetus in the uterus or other internal structures. Ultrasound scanning is often performed during pregnancy as a routine check- up. The size of the foetus is assessed and any abnormalities in growth or development can be discovered. Antenatal scans also reveal whether there is more than one foetus in the womb | |
