title: CT simulation for radiotherapy treatment planning.
abstract: The present status of CT simulation (CT sim) hardware, software and practice is reviewed, particularly with regard to the changes that have taken place over the last 5 years. The latest technology is discussed together with some recently developed techniques. The article concludes with a discussion of virtual simulation vs physical (conventional) simulation; in particular there is a review of the changes that have been made to the "Disadvantages table" presented by Conway and Robinson [1], which now make CT sim an attractive system for any radiotherapy department.
