this work, we present a 3D cardiac cine sequence based on the 3D cones
non-Cartesian trajectory which can resolve multiple cardiac phases for a 3D
volume within a single breath-held scan. The 3D cones trajectory is a fast
sampling method that enables a high degree of scan time reduction.
Furthermore, its robust motion and flow properties are beneficial for cardiac
imaging. We implement the 3D cones cine sequence using a prospectively
cardiac-triggered segmented SSFP sequence. Experimental results demonstrate
that 12 cardiac phases can be resolved for 10 contiguous slices within a
single 30-second breath-held scan.
