A Ex vivo moving platform consisting of a moving holder with four wheels moving on rails through an actuator inducing breathing motion. The ex vivo human heart B is placed on the trolley holder. C For T1ρ value assessment, regions of interest are manually drawn on the septal and anterolateral segments of the left ventricle. D Original, motion-corrected and motion-free reference T1ρ-weighted images and their corresponding T1ρ maps. E Signal intensity profiles are extracted from the T1ρ-weighted images
