CT History & Development
Timeline
| 1917 | Johann Radon demonstrated that the image of a 3-dimensional object can be recostructed from an infinite number of 2-dimsneisonal projections of the object |
| 1956 | Ronald Bracewell publishes paper mapping sunspots using a series of one-dimensional images to reconstruct a two-dimensional image using Fourier transform |
| 1958 | William Oldendorf builds a model CT scanner without a computer |
| 1960 | Oldendorf applies for a patent for his model |
| 1963 | Alan Cormack publishes results from experimental scanner using a computer to reconstruct images from data |
| 1966 | David Kuhl publishes paper with the transmission images of a subject's thorax |
| 1967 | Bracewell reconstructs lunar images without using Fourier transforms |
| 1968 | EMI patents Godfrey Hounsfieild's method apparatus and the apparatus for scanning the body with X-rays |
| 1971 | The first CT scanner, limited to the head, demonstrated by EMI at Atkinson Morley's hospital in London |
| 1972 | The first CT scanner demonstrated in the United States |
| 1973 | Robert Ledley markets ACTA, a whole body CT scanner |
| 1975 | Second gerneration Delta CT scanners are marketed GEs third generation CT scanners are marketed |
