Abstract

PURPOSE: Accurate internal target volume (ITV) estimation is essential for effective and safe radiation therapy in liver cancer. This study evaluates the clinical value of an ultraquality 4-dimensional magnetic resonance imaging (UQ 4D-MRI) technique for ITV estimation. METHODS AND MATERIALS: The UQ 4D-MRI technique maps motion information from a low spatial resolution dynamic volumetric MRI onto…
