Computed tomography--old ideas and new technology

Eur Radiol. 2011 Mar;21(3):510-7. doi: 10.1007/s00330-011-2056-z. Epub 2011 Jan 20.


Several recently introduced 'new' techniques in computed tomography--iterative reconstruction, gated cardiac CT, multiple-source, and dual-energy CT--actually date back to the early days of CT. We review the historic origins and evolution of these techniques, which may provide some insight into the latest innovations in commercial CT systems.
