Ultrasound is a medical imaging technique that uses high-frequency sound waves to create visual images of the inside of the body. It is a non-invasive procedure that does not involve radiation, making it a safe option for imaging. The sound waves are transmitted into the body, and the echoes that bounce back are captured to produce detailed images of organs, tissues, and blood flow. Ultrasound is commonly used to monitor pregnancies, evaluate the heart, liver, kidneys, and other organs, as well as detect abnormalities such as cysts or tumors. It can also guide certain medical procedures like biopsies or needle placements.

It can also guide certain medical procedures like biopsies or needle placements. The procedure typically involves applying a gel to the skin, followed by a handheld device called a transducer, which is moved over the area being examined. Ultrasound is often used in emergency situations due to its speed and ease of use. It is painless, with no known side effects or risks. The results are interpreted by a radiologist or doctor, who can provide a diagnosis based on the images produced. Overall, ultrasound is a versatile and widely used diagnostic tool in modern medicine.
