The observable periodic magnetisation induced in a spin system excited by Rabi modulated Continuous Wave excitation is exploited in this work to construct a new imaging paradigm. Localised frequency information is encoded in the steady-state Rabi harmonics, reconstructed as radial projections of proton density and back-projected to form images. This form of imaging has the potential to image samples with ultra-short T₂ decay, which is beneficial for the diagnosis of muscular skeletal injury and disease.
