Conventionally, loop coils are used for the construction of small animal transceive arrays. However, as the number of coil elements increases the size of each coil has to be reduced, since the available space is generally restricted, to comply with MRI-system specifications. As a result the RF penetration depth will be compromised. In this work, a 9.4T shielded 8-channel hybrid loop-sheet coil transceive array for small animal MRI is proposed to overcome the low RF penetration depth issue.
