This study introduces a new MRI approach using a rapidly rotating RF (RRF) transceive coil. RF coil rotation offers an additional degree of freedom for MR imaging in that it emulates a large conventional RF coil array. To test its feasibility, a small RRF transceive coil system was constructed and operated at about 1200 revolutions per minute in a 2 Tesla field. The MR images obtained were uniform and of good quality. The RRF approach may obviate the need for multiple channels and tedious RF coil decoupling.
