Ultrasound

Ultrasound is a popular diagnostic medical procedure that uses high frequency sound waves to produce dynamic images called sonograms. Ultrasound is used to 'view' organs, tissues, or blood flow inside the body. Prenatal ultrasound examinations are performed by trained professionals, such as sonographers, radiologists, and obstetricians. The prenatal ultrasound procedure involves using a transducer, which sends a stream of high-frequency sound waves into the body and detects their echoes as they bounce off internal structures such as the fetus. The sound waves are then converted to electric impulses, which are processed to form an image displayed on a computer monitor. It is from these images that videos and portraits are made using ultrasound.
