We design a novel acentric spiral pattern and combine with partial Fourier to form a new sampling strategy in 3-D Cartesian acquisition. This new strategy was implemented and tested in isotropic 3-D single breath hold cardiac cine imaging with isotropic spatial resolution and whole heart coverage. Volunteer study shows that this new sampling strategy greatly reduced the number of samples and have acceptable image quality.
