A new super-resolution (SR) method for field of view (FOV) shifted MRI is presented. In contrast to previous attempts that are based on simple FOV shifts only, the new method additionally modulates the longitudinal magnetization within the imaging plane for each shift, thus allowing the acquisition of new and independent k-space data. First SR experiments in a geometric phantom and in brain tissue of two healthy volunteers clearly demonstrate the feasibility and advantages of the new method, which has the capability to break current resolution limits in MRI.
