In this work we rapidly rotate a single RF transceive coil about the subject to excite the nuclear spin and acquire the MR signal. RF coil rotation offers a new degree of freedom for MR imaging in that it emulates a RF coil array. A rotating RF transceive system for head imaging at 2 Tesla was implemented and the acquired images exhibit good quality. The rotating RF coil approach may obviate the need for multiple signal pathways and intricate RF decoupling of many stationary array coils.
