We developed a novel flexible pad of uHDC material and characterized the RF fields in the visual cortex at 3T in a clinical 20- and 64-channel head coil with and without this pad. This pad was then utilized in an attempted to visualize optical dominance columns via high resolution fMRI images of the visual cortex in the 20-CH head coil and compared the results of with the results of an unenhanced 64-CH head coil.
