X-ray computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source.

The term “ computed tomography ,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images, or “slices.”. These slices are called tomographic ...

Jul 15, 2016 · Computed tomography (CT) was created in the early 1970s to overcome many of these limitations . By acquiring multiple x-ray views of an object and performing mathematical operations on digital data, a full 2D section of the object can be reconstructed with exquisite detail of the anatomy present ( Fig. 1-1 ).
Dec 1, 2021 · The history of computed tomography. 4 min. Ingo Zenger. Published on December 1, 2021. In London, in fall 1971, a radiologist and an engineer found themselves jumping up and down for joy – as one of them later recalled – “like football players who had just scored a winning goal.”. In their hands, the two researchers were holding a ...
Oct 7, 2016 · As conventional tomography evolved, it was still considered ineffective when it came to imaging soft tissues. Increased power and availability of computers in the 1960s sparked the research to create practical computational tomographic images. In 1967 Sir Godfrey Hounsfield invented the first CT scanner at EMI Central Research Laboratories ...
