Ultrasound imaging is a non-invasive medical 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, making it an essential tool in prenatal care and diagnosing various medical conditions. The procedure involves placing a small device called a transducer on the skin, which emits sound waves that bounce off internal structures. The reflected waves are then captured and converted into images. Ultrasound is safe, painless, and does not involve radiation, making it a preferred choice for many diagnostic applications.
