Background and purpose. Anatomic changes during head and neck radiotherapy require
replanning. The primary aim of this study is the definition of the agreement among experts in …

Deformable image registration (DIR) is a critical technic in adaptive radiotherapy (ART) for
propagating contours between planning computerized tomography (CT) images and …

Background and purpose In prostate IMRT, the objectives were to quantify, for the bladder
and the rectum:(i) the dose difference (DD) between the planned dose (PD) and the …

The aim of this study was to investigate the utility of consistency metrics, such as inverse
consistency, in contour-based deformable registration error analysis. Four images were …

Change in PET-based textural features has shown promise in predicting cancer response to
treatment. However, contouring tumour volumes on longitudinal scans is time-consuming …

PURPOSE: This work describes the clinical validation of an automatic segmentation
algorithm in CT-based radiotherapy planning for prostate cancer patients. MATERIAL AND …

The purpose of this study is to evaluate the performance variations in commercial
deformable image registration (DIR) tools for adaptive radiation therapy and further to …

Purpose: To develop a three‐dimensional (3D) deformable head‐and‐neck (H&N) phantom
with realistic tissue contrast for both kilovoltage (kV) and megavoltage (MV) imaging …

Purpose This study aimed to evaluate the accuracy of deformable image registration (DIR)
algorithms using data sets with different levels of ground-truth deformation vector fields …

Despite aggressive efforts to cure head and neck cancer patients, including altered
fractionation and the addition of chemotherapy to radiation, locoregional recurrence remains …
