Abstract
In this paper we improve the extraction of harmonic images from tagged MR images of the heart. Using simulations, we study the shapes of the spectra of harmonic images and their relation to the heart motion. The filters used to extract the harmonic images are designed based on the shape of the spectra and tuned using simulations. The design also considers additive noise and interference from other harmonic images
