In vivo imaging of the spatial arrangement of eye segments and their masses is an emerging MRI application and ultimately aims at performing MR image-based biometry. For this purpose, a six-element transceiver eye coil array (f=298 MHz) which uses loop elements is proposed. Our EMF simulations and experimental results indicate that the use of multiple surface coil transceiver loop elements yields an excellent SNR for eye imaging, affords uniform signal intensity across the eyes, and facilitates the depiction of anatomical details of the eye.
