CT scan
A CT scan , [1] also known as computed tomography scan , and formerly known as a computerized axial tomography scan or CAT scan , [3] makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional ( tomographic ) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting.

X-ray computed tomography ( X-ray CT ) is a technology that uses computer-processed X-rays to produce tomographic images (virtual 'slices') of specific areas of the scanned object, allowing the user to see inside without cutting. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional radiographic images taken around a single axis of rotation . [1] Medical imaging is the most common application of X-ray CT. Its cross-sectional images are used for diagnostic and therapeutic purposes in various medical disciplines. [2] The rest of this article discusses medical-imaging X-ray CT; industrial applications of X-ray CT are discussed at industrial computed tomography scanning . |

Computed tomography (CT), was originally known as "EMI scan" as it was developed at a research branch of EMI , a company best known today for its music and recording business. It was later known as computed axial tomography (CAT or CT scan) and body section roentgenography . It is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an object from 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 (slice) and graphein (to write). 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 beam. Although historically (see below) the images generated were in the axial or transverse plane ( orthogonal to the long axis of the body), modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures. |

Computed axial tomography (CAT) , computer-assisted tomography , computed tomography , CT , or body section roentgenography is the process of using digital processing to generate a three-dimensional image of the internals of an object from a large series of two-dimensional x-ray images taken around a single axis of rotation. The x-ray slice data is generated using an X-ray source that rotates around the object; X-ray sensors are positioned on the opposite side of the circle from the X-ray source. Many data scans are progressively taken as the object is gradually passed through the gantry. |

Computed Axial Tomography (also known as CAT , Computer Assisted Tomography , Computed Tomography , CT , or body section roentgenography ) is the process of using digital processing to generate a three-dimensional image of the internals of an object from a series of two-dimensional x-ray axial images. The individual x-ray axial slice images are taken using a x-ray tube that rotates around the object taking many scans as the object is gradually passed through the gantry. The multiple scans from each 360 degree sweep are then processed to produce a single cross-section. |

Computed Axial Tomography (CAT, now often called just Computed Tomography and CT, the actual process being a CT scan. Also called body section roentgenography or computer assisted tomography) is the process of using digital processing to generate a three-dimensional image of the internals of an object from a series of two-dimensional x-ray axial images. The individual x-ray axial slice images are taken using a x-ray tube that rotates around the object taking many scans as the object is gradually passed through the gantry.
