While fMRI at 7-Tesla can provide clinically relevant increases in functional sensitivity over 3-Tesla, it also typically uses visual and audio stimulation devices that require additional space accommodations inside the RF coil. In order to accommodate a wider range of stimulus devices than possible with high filling factor designs, a head array coil utilizing a volume transmitter and 32 receive elements for 7-Tesla was constructed inside a versatile mechanical package to support fMRI and other applications.
