X-Ray
HOLLOMAN AIR FORCE BASE, N.M. -- Senior Airman Farida Burenbeiya-Graham, a diagnostic imaging technologist, performs an X- ray. X-ray technology uses electromagnetic radiation to make images. Body parts appear light or dark due to the different rates tissues absorb the X-rays. (U.S. Air Force photo by Airman 1st Class Rachel A. Kocin)
