We show initial results with a novel reconstruction
algorithm and small modification to previous
undersampling strategies used in parallel imaging. Our
novel algorithm constrains the coil sensitivities to be
compact in the Fourier domain, and uses a small set of
samples acquired with the body coil to further constrain
the solution space. We demonstrate high-quality
magnitude and phase images can be estimated from 3D
FLASH with at least 7x reductions in scan time.
