TCTi developed 3D image capture devices and software for a wide range of applications. The technology, called Digital Surface Photogrammetry (DSP), enabled a hand-held scanner quickly and simply to capture the 3D description of complex objects such as people, products and places. TCTi developed the technology initially for commercial application in medical and entertainment markets.
Amadeus was involved in several financing rounds for TCTi starting in 1998 and helped the company focus its strategy on the medical market. In 2000, TCTi shares were listed on the UK Alternative Investment Market. In early 2002, TCTi was sold to 3Dmd, a company focusing on providing 3D technology to the healthcare market worldwide
