Results of histogram analysis. (a) Percentage of voxels in the brain that fall within the SNR ranges in the leftmost column, for each of the receive coil configurations. (b) Mean SNR within the given depth range in the leftmost column. Values represent mean and standard deviation among all subjects. P values determine the likelihood of the null hypothesis μ (64-Ch) = μ (uHDC V1). Values below 0.05 indicate statistically significant differences between the mean SNR of the two coil configurations.
