Conventional 2D cine MRI for cardiac functional measurements requires a series of breath-holds, which is usually difficult for children or sick patients and often results in non-diagnostic images. We aim to develop a fast and reliable free-breathing 3D imaging technique, which also allows subject-specific respiratory motion compensation.
