Time Division Multiplexed - Sensitivity Encoding (TDM-SENSE) with a mechanically rotating RF coil
Introduction: Recent studies [1-2] have shown that rotating an RF transceive coil (RRFC) provides a uniform coverage of the object, requires only one RF channel, averts coil-coil coupling interactions and facilitates large-scale multi-nuclear imaging. When images are reconstructed in the conventional FFT manner, motion of the coil sensitivity profile can lead to ghosting artifacts. This work presents Time Division Multiplexed Sensitivity Encoding (TDM-SENSE) scheme, as a new image reconstruction method that facilitates ghost-free image reconstructions and reductions in image acquisition time. The TDM-SENSE experiments were performed using an in-house developed RRFC system for head imaging. In one of the presented applications, alias-free head images were obtained in half the usual scan time.
