Computed tomography (CT) is a medical imaging technique employing tomography. Digital geometry processing is used to produce a three-dimensional image of the within of an object from a large series of two-dimensional X-ray images in use around a single axis of rotation. The word "tomography" is derivative from the Greek tomos (slice) and graphein (to write).
Computed tomography was at first known as the "EMI scan" as it was developed at a research branch of EMI, a company best recognized today for its music and recording business. It was later acknowledged as computed axial tomography (CAT or CT scan) and body section roentgenography.
