A method and system are described for image registration (element S6) using an information theoretic approach that can be used for correcting motion in blood flow studies as well as other applications. The joint probability distribution between two MRI (or other modality) images (element S2) is estimated where the interpolation method is referred to as a continuous histogram (element S5).
