Real‐time high soft‐tissue contrast magnetic resonance imaging (MRI) from the MR‐Linac offers the best opportunity for accurate motion tracking during radiation therapy delivery via high‐frequency two‐dimensional (2D) cine imaging. This work investigates the efficacy of real‐time organ motion tracking based on the registration of MRI acquired on MR‐Linac.
