Comparison between target margins derived from 4DCT scans and real‐time tumor motion tracking: Insights from lung tumor patients treated with robotic radiosurgery

Abstract

The use of bony alignment for CyberKnife lung stereotactic body radiation therapy requires careful considerations, in terms of the potential for increased toxicity or local miss. Our method could be used by other centers to determine the adequacy of ITV-to-PTV margins for their patients.
