Lauren Key, 20th MDSS medical maintenance NCO in charge, prepare to measure the distance from the X-ray machine to the table, Shaw Air Force Base, S.C., March 13, 2014. The purpose for the X-ray calibration and all the test involved are to make sure the density is correct and the radiation into the patient is not to much for the patient.(U.S. Air Force photo by Senior Airman Ashley L.
