Abstract:
A quick, simple set of tests has been devised to assess and record the quality assurance aspects of the Varian multi-leaf collimator (MLC) when used for clinical treatments on a regular basis. Pre-treatment, daily and weekly checks are performed by the radiographers while more detailed quality assurance is carried out at monthly and quarterly intervals by physicists.
