Abstract:
Flattening filter free (FFF) beams allow fast delivery of stereotactic radiotherapy. To evaluate biological effects of FFF in lung, we compared parenchymal changes after FFF and non-FFF stereotactic volumetric modulated arc therapy. Standardized multi-observer consensus evaluation of follow-up CT scans revealed no major differences between FFF and non-FFF.
