Time Is of the Essence: Precise Quantification of Intrafraction Baseline Positional Drift across Brain, Head-and-Neck, Thorax, Breast, and Pelvis Sites By Leveraging 100,000 IGRT Sessions

Numerous studies have quantified target baseline positional drift rates across anatomic sites; however, these investigations are often limited by surrogate localization methods (e.g., surface-guidance), single-site analyses, or limited datasets. Here, we leve...
