Although Fourier gradient phase‐encoding and Hadamard radio‐frequency encoding are two established spatial MR localization techniques, the absence of voxel‐shift and interpolation postprocessing algorithms for the latter has always placed it at a discouraging disadvantage. This article presents a method for voxel‐shift and interpolation of Hadamard‐encoded data and demonstrates both theoretically and experimentally the similarities of the respective operations between the two localization methods.
