Ultrasound imaging, also known as sonography, is a medical technique that uses sound waves to create images of the inside of the body. During the procedure, a device called a transducer is placed on the skin, which sends out extremely fast sound waves. These waves bounce off internal structures and are then captured by the transducer and displayed as images on a screen as they happen. Ultrasound imaging is commonly used to view organs, tissues, and blood flow, as well as to monitor the development of a fetus during pregnancy. It is a safe method that does not involve any surgery or needles, helping doctors diagnose and evaluate various medical conditions.
