We report on the development of a clinically practical surface coil with sufficiently high SNR and large FOV suitable to perform MRI study and quantification of the effects of monocular form-deprivation on the pattern of peripheral refractive errors and eye shape in developing rhesus monkeys using a 7 T Bruker MRI scanner. The coil was designed to fit an infant head size and its design is based on counter rotating currents resonator concept. It consists of two 180 deg. rotated split copper squares separated by 15-mil dielectric substrate. Performance of the coil was tested and also compared with a single loop surface and volume coils. As expected from simulations, the coil exhibits high SNR combined with relatively large FOV.
