Název v původním jazyce

Fluence complexity in IMRT fields and correlation with gamma analysis

Popis výsledku v původním jazyce

Our previously published method for fluence complexity calculation in IMRT fields is based on portal dose images predicted 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 amplitude of dose gradients in a field. Now the method is validated with a set of 6 patients? plans. For each patient, 4 plans with different levels of complexity have been created, using the manual smoothing tools available in Eclipse. It has been found that fluence complexity calculated with our tool is in accordance with the level of manual fluence smoothing, with the number of monitor units, the behaviour of dose-volume histogram parameters and also with the results of gamma analysis after plan verification. Our method allows to estimate fluence complexity at the planning stage and thus potentially avoid measurement of complex plans, which do not often meet t
