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 ...

A computed tomography scan (CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
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).
A device used in tomography is called a tomograph, while the image produced is a tomogram. In many cases, the production of these images is based on the mathematical procedure tomographic reconstruction, such as X-ray computed tomography technically being produced from multiple projectional radiographs.
29 paź 2021 · On Friday, October 1, 1971, a new procedure was performed to image a live patient’s brain. After a (lengthy) computer processing reconstruction delay, a remarkable image appeared on the screen of a monitor, sparking a revolution in medical imaging.
17 paź 2023 · Abstract. In 1971, the first patient CT examination by Ambrose and Hounsfield paved the way for not only volumetric imaging of the brain but of the entire body. From the initial 5-minute scan for a 180° rotation to today's 0.24-second scan for a 360° rotation, CT technology continues to reinvent itself.
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.
