![]() ![]() The objective was to determine whether dose distribution to selected structures could be improved using gEUD optimization without adversely altering the doses delivered to other structures, as in sculpting. We analyzed the effect of gEUD-based optimization parameters on plan quality. The purpose of this study was to investigate the effectiveness of gEUD optimization to fine tune the dose distributions of IMRT plans. The generalized equivalent uniform dose (gEUD) has been used in IMRT optimization as an alternative objective function to the conventional dose-volume-based criteria. With intensity-modulated radiotherapy (IMRT), a variety of user-defined dose distribution can be produced using inverse planning. Wu Qiuwen Djajaputra, David Liu, Helen H.
