Computed tomography (CT) of a human brain, from the base of the skull (top left) to the top, taken with an intravenous contrast agent. This medical imaging method employs tomography and digital geometry processing to generate a three-dimensional image of the inside of an object from a large series of two-dimensional x-ray images taken around a single axis of rotation.Image credit: Mikael Häggström
