  The aim of this study was to investigate the accuracy and tolerance of using a single data set to perform agility head Multi-Leaf Collimator (MLC) modelling in Volumetric Modulated Arc Therapy (VMAT) plans using two matched linear accelerators. First, the Express QA package provided by the system manufacturer was measured on two matched Versa HD Linear Accelerators (LINACs) at to evaluate the match credibility for the MLC parameters of the two LINACs assessed. Second, ten patients with head and neck cancer and ten patients with prostate cancer were evaluated, with and without MLC modelling, while maintaining identical optimisation constraints in the VMAT plans. All patient plans were verified using an IBA Dosimetry MatriXXEvolution array inserted into a multi cube phantom. Finally, ten head and neck clinical cases were measured using the MatriXX array on the two matched LINACs. Compar.. Read More»
