The first image scanner developed for use with a computer was a drum scanner. It was built in 1957 at the US National Bureau of Standards by a team led by Russell A. Kirsch. The first image ever scanned on this machine was a 5 cm square photograph of Kirsch's then-three-month-old son, Walden.
The idea of this approach to scanning can be traced to three sources. In 1989, the first report of a practical spiral CT scanner was presented at the RSNA meeting in Chicago by Dr. Willi Kalender5. The spiral/helical CT scanners developed after 1989 were referred to a singleslice spiral/helical or volume CT scanners.
