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.
Pfizer’s ACTA 0100 and its successor, the 200FS, were sold to hospitals worldwide between 1975 and 1977, but Pfizer lost the medical imaging market to GE Medical and Technicare, which both sold next-generation CT scanners. [35] In 1981, Pfizer sold its CT business to Elscint. As the use of CT scanners became widespread, Ledley rose to ...
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]
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.

In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...

Electron beam CT scanners are considered a fifth generation CT scanner, with first generation being the pencil beam with translation and rotation, second generation being a fan beam with similar motion to its predecessor, third generation having both rotating fan beam and detectors and fourth generation being a fan beam with a rotating movement but fixed detector.
