What technique uses sound waves to create images of the internal structures of the body?

Ultrasound imaging employs sound waves to produce detailed images of the internal structures of the body. This technique utilizes high-frequency sound waves that are emitted from a transducer, which then travel through the body and reflect off various tissues and organs. The reflecting sound waves are captured by the same transducer and converted into images that can be viewed on a monitor.

Ultrasound is particularly useful for visualizing soft tissues and fluids, making it an essential tool in medical diagnostics, especially in obstetrics, cardiology, and examining organs like the liver and kidneys. Its non-invasive nature and the absence of ionizing radiation make it a safe option for both patients and healthcare providers.
