Tagging MR is still considered the gold standard for motion quantification in the heart walls. Although there are several methods for postprocessing this kind of images, harmonic phase methods such as HARP and SinMod has been widely used because of its simplicity and reliable results. In this work, we present a novel Harmonic Phase Interpolation (HARP-I) for the estimation of motion, which has low noise sensitivity, performs better than HARP and SinMod, and does not depend on temporal resolution.
