“…Cobalt-60 (Co-60) teletherapy 1,2 was the most popular radiation therapy unit from mid-1950s to 1960s and introduced high energy photon radiation treatment. In the past five decades, tremendous research and innovation has gone into improving radiation therapy, particularly, through the development of intensity modulated radiation therapy (IMRT) techniques.…”
These results confirm that Co-60 tomotherapy is capable of providing state-of-the-art conformal dose delivery and could be used for the treatment of targets in both small and larger separation anatomical regions.

“…By surrounding such a source with sufficient lead protection and fitting a shutter and an efficient collimating system, a beam of gamma rays is obtained comparable in every way with the beam of x-rays produced by a supervoltage machine. One example of such a therapy unit has been described by Green and Errington (1952) and another by Johns, Bates and Watson (1952). An improved collimating system for the second unit has more recently been fitted (Johns and MacKay, 1954).…”
This article reviews the history and background of Cobalt and discusses the physics of activation, the specification of source strength, the unit design, and clinical applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
