Experimental 1/g-factor maps in an axial slice at the level of the prostate in the human torso for the eight- and sixteen-channel arrays. One-dimensional reduction factors from 2 to 8 in the left-right direction are shown. The sixteen-channel array displays substantial improvements in g-factors over the eight-channel. For example, at a reduction factor of 4, the eight-channel array has a mean reduction factor of 1.48 with a maximum g-factor of 2.43 while the sixteen-channel has a mean g-factor of 1.11 and a maximum g-factor of 1.36.
