Radiotherapy treatment planning of complex radiotherapy techniques, such as intensity
modulated radiotherapy and volumetric modulated arc therapy, is a resource-intensive …

Radiation therapy treatments are typically planned based on a single image set, assuming
that the patient's anatomy and its position relative to the delivery system remains constant …

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 …

As deformable image registration makes its way into the clinical routine, the summation of
doses from fractionated treatment regimens to evaluate cumulative doses to targets and …

Online adaptive radiation therapy aims at adapting a patient's treatment plan to their current
anatomy to account for inter-fraction variations before daily treatment delivery. As this …

Purpose Retrospective studies were performed to evaluate the accuracy of automatically
mapped structures and dosimetric consequences of daily online adaptive radiation therapy …

In the last decade, many efforts have been made to characterize anatomic changes of head
and neck organs at risk (OARs) and the dosimetric consequences during radiotherapy. This …

Quantitative validation of deformable image registration (DIR) algorithms is extremely
difficult because of the complexity involved in constructing a deformable phantom that can …

Abstract Organ-at-risk (OAR) delineation is a key step for cone-beam CT (CBCT) based
adaptive radiotherapy planning that can be a time-consuming, labor-intensive, and subject …

Purpose Anatomical variations occur during head and neck (H&N) radiotherapy treatment.
kV cone‐beam computed tomography (CBCT) images can be used for daily dose monitoring …
