We performed a human brain imaging study using a prototype conformal helmet constructed with ultrahigh dielectric constant (uHDC) materials inserted into a standard 20-Ch head coil at 3T. We characterized the transmit and receive performance of the helmet by comparing to results using the 20-Ch and 64-Ch head coil (n=5 subjects) without the uHDC helmet. The SNR and its spatial distribution within the cerebrum using the 20-Ch Coil with uHDC Helmet is comparable to that of the 64-Ch Coil. Further improvement of the uHDC helmet insert is expected to significantly improve the performance of standard receive arrays for brain imaging.
