A 7T 8-channel transmit/receive volume head coil was designed, built, and tested. It is capable to produce transmit fields in the human brain of more than 50 µT when exploiting the RF peak power design limits (5kW). This high B1+ efficiency is necessary either for single voxel spectroscopy to reduce chemical shift artifacts or for pTx based feature selective excitation methods. The shielded decoupled loop array coil fits into B0 shim inserts and enables accommodation of optical stimulation equipment.
