While mechanically rotating a RF coil about an object being imaged brings a number of hardware advantages as was shown in recent studies, the approach violates the time-invariant definition of the Fourier Transform. This work presents Time Division Multiplexed - Sensitivity Encoding (TDM-SENSE) as a new alias-free image reconstruction and scan time acceleration scheme dedicated to the rotating RF coil (RRFC). In this initial study, two-fold scan time reduction was achieved by increasing the signal sampling rate and the angular frequency of coil rotation.
