G-Factor maps of a coronal slice of phantoms with L/R and S/I acceleration using the 8-channel standard coil (column 1) and the 16-channel custom coil (column 2). We acquired the full k-space data with a 3D SPGR sequence and applied SENSE acceleration in post-processing – 2× S/I and 1×, 2×, 3×, or 4× L/R. We applied background thresholding and smoothing prior to g-factor calculation. The 16-channel custom coil had much lower mean g-factors when compared to the 8-channel standard coil for all SENSE accelerated images.
