A combination of novel acentric spiral pattern and partial Fourier acquisition method was designed and tested in 3-D cardiac cine imaging with isotropic spatial resolution and whole heart coverage. 
Figure 1. The acentric Cartesian spiral pattern in PE-SPE plane, with matrix size 128 x 64, 75% partial Fourier in both directions.
Figure 2. The upper row are eight short axis slices at the end of systole; the lower row are the corresponding eight slices at the end of diastole. The distance between two adjacent slices shown is 8.4 mm (four slice thickness).
