Evaluation of OAR dose sparing and plan robustness of beam-specific PTV in lung cancer IMRT treatment

Evaluation of OAR dose sparing and plan robustness of beam-specific PTV in lung cancer IMRT treatment:



Margins are employed in radiotherapy treatment planning to mitigate the dosimetric effects of geometric uncertainties for the clinical target volume (CTV). Here, we proposed a margin concept that takes into co...
