In ocular imaging, the development of dedicated MRI coils is useful to monitoring the visual cortex and to determinate the damage in the visual pathway before a surgery. We developed an 8-channel flexible array for ocular fMRI. The coil is comprised of two pieces with four channels each. SNR-maps and in-vivo images were compared with a conventional head-coil at 1.5T. The 8-channel flexible array shows 200% SNR improvement at the surface and 25% at the center of the phantom. In-vivo images acquired with the 8-channel flexible array have also shown better image quality throughout the whole visual pathway.
