How Does an Ultrasound Works? Ultrasound waves are produced by a transducer, which can both emit ultrasound waves, as well as to detect the ultrasound echoes reflected back. In most cases, the active elements in ultrasound transducers are made of special ceramic crystal materials called piezoelectrics. These materials can produce sound waves when an electric field is applied to them, but can also work in reverse, producing an electric field when a sound wave hits them. When used in an ultrasound

Indication of ultrasound in pregnancy Ultrasound is a commonly used diagnostic imaging technique during pregnancy. It uses high-frequency sound waves to create real-time images of the developing fetus and the mother's reproductive organs. Ultrasound has several indications in pregnancy, including: Confirming pregnancy: Ultrasound is often performed early in pregnancy to confirm the presence of a viable pregnancy, determine the gestational age, and assess the number of fetuses.
