A mechanically rotating RF transceive system and method for applications in Magnetic Resonance

Introduction: A new concept relating to a fast mechanically rotating radio-frequency (RRF) transceive coil and method for application in MRI is presented. The introduction of controlled RF system rotation as additional degree of freedom during imaging facilitates the use of (at least) one coil sensitivity pattern to effectively emulate a conventional RF coil array over time. This approach aims to substantially diminish the number of coil elements and channels, lumped circuit components and tedious mutual decoupling while preserving the benefits of very large RF coil arrays. This feasibility study presents and discusses first experimental results of the RRF system in in-vitro imaging and spatially selective excitation.
