The history of X-ray computed tomography (CT) dates back to at least 1917 with the mathematical theory of the Radon transform. [1][2] In the early 1900s an Italian radiologist named Alessandro Vallebona invented tomography (named "stratigrafia") which used radiographic film to see a single slice of the body. [3][4][5][6][7][8][9][10][11] It was ...

- CT scan
A specific measure, termed the computed tomography dose index (CTDI), is commonly used as an estimate of the radiation absorbed dose for tissue within the scan region, and is automatically computed by medical CT scanners.
Tomografia komputerowa, TK, CT (od ang. computed tomography) – rodzaj tomografii rentgenowskiej, metoda diagnostyczna pozwalająca na uzyskanie obrazów tomograficznych (przekrojów) badanego obiektu. Wykorzystuje ona złożenie projekcji obiektu wykonanych z różnych kierunków do utworzenia obrazów przekrojowych (2D) i przestrzennych (3D).

Tomography is a technology that uses a tomographic optical system to obtain virtual 'slices' (a tomographic image) of specific cross section of a scanned object, allowing the user to see inside the object without cutting.
