The conventional RF coil arrays developed for head imaging usually have poorer sensitivity to the dorsal areas of the brain because the coil elements wrap around the head such that they are more sensitive to anterior, posterior, left and right areas of the brain. In this study, two different end cap designs and a Fo8 element placed on top of the head were investigated using simulations in order to improve SNR in sensorimotor and parietal areas.
