Ultrasound systems are medical devices that use high-frequency sound waves to create images of the inside of the body. These systems consist of a transducer, which emits sound waves and captures the echoes that bounce back from tissues and organs. The data is then processed to produce real-time images, helping healthcare professionals diagnose and monitor various conditions. Commonly used in prenatal care, ultrasound is also valuable for examining organs like the heart, liver, and kidneys. The procedure is non-invasive, safe, and does not involve radiation, making it a preferred choice for many diagnostic applications in medicine.
