Hounsfield's prototype CT scanner A historic EMI-Scanner Mark I, alongside the minicomputer used to process the CT image data. 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 ...

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.
17 paź 2023 · 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.
1 gru 2021 · The engineer, Godfrey Hounsfield, had developed the new X-ray technology almost single-handedly. With the prototype of his “3D X-ray machine,” Hounsfield ushered in the development of what has become one of the most important techniques in medical imaging: computed tomography (CT).
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.
11 sie 2021 · Purpose: We provide a review of the key computed tomography (CT) technologies developed since the late 1980s and offer an overview of one of the future technologies under development. The focus of this review is mainly on the hardware and system development.
The excitement is palpable when a new imaging procedure revolutionizes the world of medicine: computed tomography (CT). In 1975, Siemens launches the first computer tomograph on the market, the SIRETOM head scanner. Enjoy the journey.
