IMRT fluence complexity calculation
Original language description
Introduction Fluence complexity of Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) techniques in external beam radiotherapy plays an important role in delivering the right dose to the right place. However, excessfluence complexity causes problems during plan calculation, plan verification and plan delivery. A new method for estimation of fluence complexity in IMRT fields is proposed. Method Unlike other previously published works, it is based on portal images calculated by the Portal Dose Calculation algorithm in Eclipse (version 8.6, Varian Medical Systems) in the plane of the EPID aS500 detector (Varian Medical Systems). Fluence complexity is given by the number and the amplitudes of dose gradients in these matrices. Our method is validated using a set of clinical plans where fluence has been smoothed manually so that each plan has a different level of complexity. Fluence complexity calculated with our method is compared to results of plan ve
