Sonography: What it is and why it's growing in the health care field

Sonography is a painless medical procedure that uses high-frequency sound waves to produce visual images of organs, tissues and blood flow inside the body. It was first used in obstetrics to look at fetal development in the 1970s, but since then has moved to multiple branches of health care and is used to examine the abdomen, breasts, prostate, female reproductive organs, heart, blood vessels and other areas. Sonography is used in both a diagnostic and therapeutic capacity.
