In this
study, we proposed a respiratory and cardiac dual soft-gated technique that
efficiently suppresses respiratory motion and resolves cardiac motion in 4D cardiovascular MRI. Comparing with existing methods that exploited data redundancy
in respiratory and cardiac dimensions using joint reconstruction, proposed
method weights data consistency according to the degree of motion corruption. A
big advantage of this approach is its short reconstruction time and low computation
burden, making it feasible for practical usage.
