Mapping motion from 4D‐MRI to 3D‐CT for use in 4D dose calculations: A technical feasibility study

Abstract

The authors have demonstrated that motion information from 4D-MRI can be used to generate realistic 4D-CT data sets on the basis of a single static 3D-CT data set. 4D-CT(MRI) presents a novel approach to test the robustness of treatment plans in the circumstance of patient motion.
