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.
The first computed tomography (CT) system capable of producing images of any part of the human body without the need for a cumbersome "water tank" was the Automatic Computerized Transverse Axial (ACTA) scanner, designed by Dr. Robert S. Ledley, DDS, at Georgetown University.
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).
17 paź 2023 · 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. This article describes key historical milestones in CT technology from the earliest days of CT to the present, with a look toward the future of this essential imaging modality.
With the increasing power and availability of computers in the 1960s, research began into practical computational techniques for creating tomographic images, leading to the development of computed tomography (CT).
Computed Tomography (CT) builds on developments in two fields - X-ray imaging and computing. X-rays were discovered in 1895 and within a few years were an established medical tool. By the 1930s, tomography was being developed, enabling the visualisation of sections through a body.
7 paź 2016 · For now, let’s take a trip down memory lane and explore how CT has changed over the last 50 years. In the early 1900s an Italian radiologist named Alessandro Vallebona invented tomography which used radiographic film to see a single slice of the body.
