The computed tomography (CT) is a medical imaging method employing tomography. The geometry of digital processing is used to generate three-dimensional image of an object inside a large series of two-dimensional X-ray images taken around a single axis of rotation. The word tomography is derived from the Greek Tomos (tranche) and graphein (write). The computer tomography was originally known as EMI scan as it was developed by a research directorate of EMI, a company best known today for its music and business registration. It was later known as computed axial tomography (CAT or CT scan) and body section rontgenography.
CT produced a volume of data that can be handled through a process known as windowing, to demonstrate the various structures depending on their ability to block the X-ray/Röntgen beam. Although history images were generated in the axial and transverse plane (perpendicular to the axis along the body), modern scanners allow this volume of data to be reformatted in various plans or even as volumetric (3D) representations of structures. Although most common in health care, CT is also used in other areas, for example tests of materials, not destructive. Another example is the project DigiMorph at the University of Texas at Austin who uses a CT scanner to study biological and paleontological specimens.
