Dose uncertainties in IMPT for oropharyngeal cancer in the presence of anatomical, range, and setup errors.
PURPOSE Setup, range, and anatomical uncertainties influence the dose delivered with intensity modulated proton therapy (IMPT), but clinical quantification of these errors for oropharyngeal cancer is lacking. We quantified these factors and investigated treatment fidelity, that is, robustness, as influenced by adaptive planning and by applying more beam directions. METHODS AND MATERIALS We us...
متن کاملEffect of patient setup errors on simultaneously integrated boost head and neck IMRT treatment plans.
PURPOSE The purpose of this study is to determine dose delivery errors that could result from random and systematic setup errors for head-and-neck patients treated using the simultaneous integrated boost (SIB)-intensity-modulated radiation therapy (IMRT) technique. METHODS AND MATERIALS Twenty-four patients who participated in an intramural Phase I/II parotid-sparing IMRT dose-escalation prot...
