Portable MRI can be possible by eliminating gradient coils and B₀ homogeneity requirements. Relaxing the B₀ homogeneity requirements leads to non-uniform B₀ field. In-homogeneous B₀fields have the potential to encode spatial information in one direction for use in novel image encoding schemes. We investigated the possibility of image reconstruction of the signal from a non-uniform rotating magnetic field and two rotating RF receivers. Our results indicate that this is a feasible approach.
