Definition and History of CT


Computed Tomography (CT) is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an objectfrom 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).


1967 : The idea of a CT scanner is conceived by Godfrey Newbold Hounsfield.

1972 : The first commercially viable CT scanner was invented by Hounsfield in Hayes, England.

1979 : Nobel Prize in medicine for Hounsfield and Cormack.

In the late 80s Computed Tomography has been first utilized for Industrial purposes as an NDT technique (Non Destructive Testing).

Today Computed Tomography and Micro Computed Tomography is a efficient and reputable NDT that provides an entire 100% inspection and accurate 3D volume modeling of almost any object.
