An ultrasound examination is a medical imaging technique that uses high-frequency sound waves to create images of the inside of the body. It is commonly used to visualize organs, tissues, and blood flow, helping doctors diagnose various conditions. The procedure is non-invasive and does not involve radiation, making it safe for patients, including pregnant women. During the examination, a transducer is placed on the skin, which emits sound waves that bounce off internal structures. The returning echoes are then converted into images displayed on a monitor. This allows healthcare providers to assess the health of organs such as the heart, liver, and kidneys.
