National Audit of Quality Assurance for IMRT and VMAT

In February 2014, the NCS installed a new subcommittee to validate QA methods for Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) delivery techniques in the Netherlands.

The QA was assessed by comparing the institutes QA with that of the audit, consisting of an ionisation chamber measurement, a film measurement and a 2D array measurement. The general finding is that QA procedures in the Netherlands are excellent.

Along with the report comes the Working instructions which may help others to devise their own audit.

The NCS frequently publishes reports for fellow professionals in which recommendations are given for various quality control procedures or otherwise. The members of the NCS board and the members of the concerning subcommittee do not claim any authority exceeding that of their professional expertise. Responsibility on how the NCS recommendations are implemented lies with the user, taking into account the practice in his/her institution.
