“Radiomics” refers to the extraction and analysis of large amounts of advanced quantitative
imaging features with high throughput from medical images obtained with computed …

PURPOSE: To review the state of the art in image-guided precision conformal radiotherapy
and to describe how helical tomotherapy compares with the image-guided practices being …

PURPOSE: Many patients receiving fractionated radiotherapy (RT) for head-and-neck
cancer have marked anatomic changes during their course of treatment, including shrinking …

PURPOSE: To quantify the multi-institutional and multiobserver variability of target and
organ-at-risk (OAR) delineation for breast-cancer radiotherapy (RT) and its dosimetric …

Gross tumor volume (GTV) and clinical target volume (CTV) delineation are two critical steps
in the cancer radiotherapy planning. GTV defines the primary treatment area of the gross …

Purpose: To quantify interobserver variation in gross tumor volume (GTV) localization using
CT images for patients with non-small-cell lung carcinoma and poorly defined tumors on CT …

Purpose: To compare source-to-background ratio (SBR)-based PET-CT auto-delineation
with pathology in non–small-cell lung cancer (NSCLC) and to investigate whether auto …

Background and purpose: To determine the inter-observer variation in gross tumor volume
(GTV) definition in lung cancer, and its clinical relevance. Material and methods: Five …

To evaluate the impact of interobserver variability in the contouring of gross tumor volumes
(GTVs) and clinical target volumes (CTVs) on the global geometric accuracy in radiation …

Purpose: To assess the need for gross tumor volume (GTV) delineation protocols in head-
