Background Head and neck cancers are commonly treated with radiation therapy, but due to
possible volume changes, plan adaptation may be required during the course of treatment …

BackgroundThis is a prospective study to evaluate the dosimetric benefits of treatment plan
adaptation for patients who had undergone repeat computed tomography (ReCT) and re …

Purpose: The aim of this study was to evaluate the appropriateness of using computed
tomography (CT) to cone‐beam CT (CBCT) deformable image registration (DIR) for the …

During radiation therapy of head and neck cancer, the decision to consider replanning a
treatment because of anatomical changes has significant resource implications. We …

Background and purpose Adaptive radiotherapy (ART) decision-making benefits from
dosimetric information to supplement image inspection when assessing the significance of …

Background Adaptive radiation therapy (ART)“flags,” such as change in external body
contour or relative weight loss, are widely used to identify which head and neck cancer …

Purpose. Evaluating a method for anatomic changes assessment and actually delivered
doses during head and neck (H&N) cancer radiotherapy (RT) utilizing volumetric images …

Background During a course of radiation therapy, anatomical changes such as a decrease
in tumour size or weight loss can trigger the need for repeating a computed tomography (CT) …

Purpose To estimate the delivered dose to targets and organs at risk for head and neck
radiation therapy by accumulating the dose using 3 deformable image registration (DIR) …

Background and purpose To develop and validate an adaptive intervention strategy for
radiotherapy of head-and-neck cancer that accounts for systematic deformations by …
