Current radiotherapy imaging protocols are insufficient to decouple and quantify cardiac motion, limiting substructure-specific motion considerations in treatment planning. We propose a 5D-MRI workflow for substructure-specific motion analysis, with future extension to margin calculation.\n  Approach: Our 5D-MRI workflow was implemented for 10 healthy volunteers, ranging from 23 to 65 years old, reconstructing images for end-exhale/inhale and active-exhale/inhale for end-systole/diastole.
