Abstract

Purpose: The objective of this project was to define consensus guidelines for delineating organs at risk (OARS) for head and neck radiotherapy for routine daily, practice and for research purposes. Methods: Consensus guidelines were formulated based on in-depth discussions of a panel of European, North American, Asian and Australian radiation oncologists. Results: Twenty-five OARS in the head and neck region were defined with a concise description of their main anatomic boundaries. The Supplemental material provides an atlas of the consensus guidelines, projected on 1 mm axial slices. The atlas can also be obtained in DICOM-RT format on request. Conclusion: Consensus guidelines for head and neck OAR delineation were defined, aiming to decrease interobserver variability among clinicians and radiotherapy centers. (C) 2015 The Authors.
