A large-field-of-view 16-channel circular loop receive array with a volume transmit coil for the human forearm, wrist and hand imaging at 7 Tesla was constructed. While the volume transmit coil yields homogeneous transmit field distribution along the 350-mm in length , the 16-channel receiver array enables two times faster imaging with a similar MR image quality. In conclusion, the use of this large field-of-view RF coil configuration for a total MR protocol of 15 minutes is feasible, and it enables visualization of different anatomical structures on the human forearm and hand at 7 Tesla.
