Manifold learning approaches can be applied in MRI to
extract meaningful dimensions (manifolds) from the
high-dimensional set of images. In this work, we propose
a novel manifold learning based framework for cardiac
and respiratory self-gating cardiac CINE MRI. Results
show that the proposed approach estimates accurate
cardiac and respiratory gating signals from ECG-free
free breathing data and use these to achieve high
spatial and temporal quality in retrospectively
reconstructed CINE images.
