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 B0 fields 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.
