Pregnancy ultrasound examination. Hospital doctor using an ultrasound transducer to scan the abdomen of a pregnant woman. The transducer emits high- frequency sound waves and detects the reflected echoes. The results are being displayed on the screen at upper left, showing the unborn child developing in its mother's uterus. This safe, and non-invasive procedure is used routinely in pregnancy to assess the growth and health of the developing foetus, and to detect any abnormalities. Photographed in 2006, in maternity house 5 in Rostov, Russia.
