Sir Godfrey Newbold Hounsfield CBE FRS HonFREng [1] (/ ˈhaʊnzfiːld / HOWNZ-feeld; 28 August 1919 – 12 August 2004) [2][3][4][5][6] was a British electrical engineer who shared the 1979 Nobel Prize for Physiology or Medicine with Allan MacLeod Cormack for his part in developing the diagnostic technique of X-ray computed tomography (CT). [7 ...
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 ...
The first commercially viable CT scanner was invented by Godfrey Hounsfield in 1972. [212] It is often claimed that revenues from the sales of The Beatles' records in the 1960s helped fund the development of the first CT scanner at EMI. The first production X-ray CT machines were in fact called EMI scanners. [213]
Robert Ledley at the exhibit of the ACTA whole-body CT scanner at the Smithsonian’s National Museum of American History. Ledley is most widely known for his 1970s efforts to develop computerized tomography (CT) or CAT scanners. This work began in 1973, when the NBRF lost most of its NIH funding due to federal budget cuts.
Allan MacLeod Cormack (February 23, 1924 – May 7, 1998) was a South African American physicist who won the 1979 Nobel Prize in Physiology or Medicine (along with Godfrey Hounsfield) for his work on X-ray computed tomography (CT), a significant and unusual achievement since Cormack did not hold a doctoral degree in any scientific field.

Cone Beam CT scanner. MeSH. D054894. Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone. [1]
MeSH. D014057. OPS-301 code. 3-26. [edit on Wikidata] Electron beam computed tomography (EBCT) is a specific form of computed tomography (CT) in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures that never stop moving ...
MeSH. D036542. Spiral computed tomography, or helical computed tomography, is a computed tomography (CT) technology in which the source and detector travel along a helical path relative to the object. Typical implementations involve moving the patient couch through the bore of the scanner whilst the gantry rotates.
