Intrafraction motion analysis in online adaptive radiotherapy for esophageal cancer

Physics and Imaging in Radiation Oncology, 2023
Intrafraction motion during magnetic resonance (MR)-guided dose delivery of esophageal cancer tumors was retrospectively analyzed. Deformable image registration of cine-MR series resulted in gross tumor volume motion profiles in all directions, which ...

Adaptive margins for online adaptive radiotherapy [PDF]

Physics in Medicine & Biology, 2022
Abstract Objective. In online adaptive radiotherapy a new plan is generated every fraction based on the organ and clinical target volume (CTV) delineations of that fraction. This allows for a planning target volume margin that does not need to be constant over the whole course of treatment, as is the case in ...
