X-ray computed tomography |X-ray computed tomography| A patient
is receiving a CT scan for cancer. Outside of the scanning room
is an imaging computer that reveals a 2D image of the body's
interior. X-ray computed tomography, also computed tomography
(CT scan) or computed axial tomography (CAT scan), is a medical
imaging procedure that utilizes computer-processed X-rays to
produce tomographic images or 'slices' of specific areas of the
body. These cross-sectional images are used for diagnostic and
therapeutic purposes in various medical disciplines. 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 that can be manipulated, through a
process known as "windowing", in order to demonstrate various
bodily structures based on their ability to block the X-ray
beam. Although historically the images generated were in the
axial or transverse plane, p
