Free-breathing 3D cine steady-state free precession (SSFP) sequence with radial phyllotaxis trajectory is recently performed for making cardiac magnetic resonance imaging (MRI) exams easy and more comfortable for patients. Phyllotaxis trajectory is susceptible to the eddy current artifact due to a large gradient change during the 3D cine SSFP acquisition for measuring the centerline of k-space. We, therefore, developed and validated a novel leaf trajectory that minimizes the gradient change, and eddy current.
