The respective roles of the simulator and computed tomography in radiotherapy planning: a review

Abstract

The advent of computed tomography (CT) scanners and the development of a CT facility on treatment simulators has provided an array of expensive equipment for use in radiotherapy treatment planning. The object of this paper is to review the requirements necessary for accurate radiotherapy planning and to present guidelines regarding the system which appears best suited to plan individual tumour sites, based on our experience of CT scanning and related techniques over the past 6 years.
