Abstract

The calculation verification of irradiation time or monitor units (MU) plays an important part in radiation oncology quality assurance. The method is performed by an independent physicist who does not involve in the planning procedure. It could be basically calculated by hand using look-up tables of parameters and correction factors or more modern processes using complex calculation algorithms and heterogeneity correction software. The calculation should be verified prior to the treatment to ensure that the dose is accurately and safely delivered. The purpose of this article is to clarify the process of MU calculation verification in radiotherapy and provide guidance for the action levels.
