Computed tomography
Computed tomography (CT) is a medical imaging method that employs tomography. Digital geometry processing is used 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. CT produces a volume of data which can be manipulated, through a process known as windowing, in order to demonstrate various structures based on their ability to block the X-ray/Rontgen beam. Modern CT scanners allow the volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures. The links shown on this page feature the key word ′Computed tomography’ in their stories:
