Charged particle beam radiotherapy requires dedicated measures to compensate for the
dosimetric influence of inter-and intra-fractional target motion. Independent of the delivery …

Background: Deformable image registration (DIR) is increasingly used in the field of
radiation therapy (RT) to account for anatomical deformations. The aims of this paper are to …

Purpose: To utilize a deformable phantom to objectively evaluate the accuracy of 11 different
deformable image registration (DIR) algorithms. Methods: The phantom represents an axial …

BACKGROUND AND PURPOSE: Weight loss, tumor shrinkage, and tissue edema induce
substantial modification of patient's anatomy during head and neck (HN) radiotherapy (RT) …

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

BACKGROUND AND PURPOSE: Anatomic changing frequently occurred during
fractionated radiotherapy. The aims of this study were to model the potential benefit of …

Nonrigid image registration is widely used to estimate tissue deformations in highly
deformable anatomies. Among the existing methods, nonparametric registration algorithms …

Purpose: Recent years have witnessed tremendous progress in image guide radiotherapy
technology and a growing interest in the possibilities for adapting treatment planning and …

The advent of readily available temporal imaging or time series volumetric (4D) imaging has
become an indispensable component of treatment planning and adaptive radiotherapy …

Abstract In the United States, more than half of all new invasive cancers diagnosed are non-
small cell lung cancer, with a significant number of these cases presenting at locally …
