Tumor motion imaging is of vital importance in managing mobile cancers in radiation therapy. However, current 4D-MRI techniques are inefficient and ineffective, potentially leading to suboptimal and inaccurate results. To solve this problem, we propose a novel four-dimensional magnetic resonance fingerprinting (4D-MRF) technique for radiation therapy applications. Our proposed method has been validated through simulations and in-vivo volunteer experiment.
