The first commercially viable CT scanner was invented by Godfrey Hounsfield in 1972. [213] 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. [214]
The portable CT scanner does not replace the fixed CT suite. An example of this type of machine is the Siemens Healthineers SOMATOM On.site. In 2008 Siemens introduced a new generation of scanner that was able to take an image in less than 1 second, fast enough to produce clear images of beating hearts and coronary arteries.
Bernard M. Gordon founded Gordon Engineering in 1963. The company is later renamed to Analogic Corporation in 1967. [5] While at Analogic, Gordon and his engineering team conceived and developed the first digital waveform analyzing and computing instrumentation; "instant imaging" Computed Tomography (CT) system; portable, mobile CT scanner; and the first three-dimensional, multi-slice, dual ...
On 1 October 1971, CT scanning was introduced into medical practice with a successful scan on a cerebral cyst patient at Atkinson Morley Hospital in Wimbledon, London, United Kingdom. [16] In 1975, Hounsfield built a whole-body scanner. The principles of computed tomography developed by Hounsfield remain in use today (2022).
These scanners could scan the body in 2–5 seconds, thereby eliminating motion artifacts due to breathing. The HPS 1440 scanner was introduced in 1985 as an ultra high resolution CT scanner. These scanners were of the fourth generation design, in which there was a stationary ring of detectors and the x-ray tube rotating inside the detector ring.
The machine had 30 photomultiplier tubes as detectors and completed a scan in 9 translate/rotate cycles, much faster than the EMI-scanner. It used a DEC PDP-11/34 minicomputer both to operate the servo-mechanisms and to acquire and process the images. Most importantly, ACTA could scan the entire body, whereas the EMI-scanner could only scan the ...
In 1972, the first commercial CT scanner for clinical use went into operation at Atkinsons Morley Hospital in London. Its inventor was the English engineer Godfrey Newbold Hounsfield (1919-2004), who shared the 1979 Nobel Prize in Medicine with Allan McLeod Cormack (1924-1998) for his pioneering work in the field of computed tomography.
1884: The Maxim gun, the first self-powered machine gun invented by Sir Hiram Maxim (1840–1916); American-born, Maxim moved from the United States to England in 1881, becoming a (naturalised) British subject. The Maxim gun was financed by Albert Vickers of Vickers Limited and produced in Hatton Garden, London. It has been called "the weapon ...
