X-ray vision
Mr. Yi Hwan Hyung, a computed tomography technologist, prepares to run a computed tomography of Staff Sgt. Ray Winstead, 51st Fighter Wing, at the base hospital Tuesday. The CT is used to generate a three-dimensional image of an object’s inside from a large series of two-dimensional X-ray images taken around a single axis of rotation.
