The current paradigm of radiation therapy has the treatment planned on a snapshot dataset
of the patient's anatomy taken at the time of simulation. Throughout the course of treatment …

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 …

Image registration and fusion algorithms exist in almost every software system that creates
or uses images in radiotherapy. Most treatment planning systems support some form of …

PURPOSE: To assess the accuracy, reproducibility, and computational performance of
deformable image registration algorithms under development at multiple institutions on …

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 …

The actual distribution of radiation dose accumulated in normal tissues over the complete
course of radiation therapy is, in general, poorly quantified. Differences in the patient …

The modeling of respiratory motion is important for a more accurate understanding and
accounting of its effect on dose to cancers in the thorax and abdomen by radiotherapy. We …

MRI-linear accelerator (MR-linac) devices have been introduced into clinical practice in
recent years and have enabled MR-guided adaptive radiation therapy (MRgART). However …

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