NEW METHOD FOR ESTIMATION OF FLUENCE COMPLEXITY

Popis výsledku v původním jazyce

IMRT planning and verification is a complex and time-consuming process. At busy clinics this can lead to contraindication of IMRT for patients who would otherwise profit from the technique. However, IMRT verification can be simplified without compromising patient safety. One such way is suggested in our work. A new method for estimation of fluence complexity in IMRT fields is proposed. Unlike other previously published works, it is based on portal images calculated by the PDC algorithm in Eclipse (version 8.6, Varian Medical Systems) in the plane of the EPID aS500 detector. 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 tool is in accordance with the different levels of smoothing and correlates well with DVH parameters. Thus, it is possible to estima
