U.S. Air Force Staff. Sgt. Nance Pea, the 35th Surgical Operations Squadron ultrasound NCO in charge, performs an ultrasound on a patient at Misawa Air Base, Japan, Sept. 14, 2017. This procedure allows technicians to look at organs in the abdomen, including the liver, gallbladder, spleen, pancreas and kidneys. The machine sends out high-frequency sound waves reflecting off body structures, then a computer receives these waves and uses them to create a picture. (U.S. Air Force photo by Airman Xiomara M.
