Geometric characterization of an electromagnetic surface tracking system in a radiation therapy environment

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Background Despite advances in image‐guided radiation therapy (IGRT), real‐time, soft‐tissue‐based, volumetric motion monitoring remains unsolved. Integrated MRI+Linac systems are a solution, but are costly and complex. X‐ray and optical photogrammetry‐based systems have their limitations.

Using adaptive magnetic resonance image‐guided radiation therapy for treatment of inoperable pancreatic cancer

Cancer Medicine, 2019
Background Adaptive magnetic resonance imaging‐guided radiation therapy (MRgRT) can escalate dose to tumors while minimizing dose to normal tissue. We evaluated outcomes of inoperable pancreatic cancer patients treated using MRgRT with and without dose ...
