Body-Coil-Constrained Estimation (BoCCE): joint estimation of signal and coil sensitivities from weighted, under-sampled k-space measurements using a novel sampling strategy and associated reconstruction algorithm

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.
