Demonstration of approximate orthogonality between metabolite spectra obtained from in vivo OVS scan and lipid spectra from high resolution in vivo acquisition. In (a), the lipid and metabolite spectra with the highest orthogonality are plotted. In (b), the components of the metabolite spectrum that are orthogonal and parallel to the lipid spectrum for the best case in (a) are overplotted. The actual metabolite spectrum (in blue) is totally occluded by the orthogonal component (in orange). In (c), the lipid and metabolite spectra that are least orthogonal are depicted. In (d), the orthogonal and parallel components of the metabolite spectrum are overplotted for the worst case in (c). Panel (e) depicts the methodology used in computing the orthogonal and parallel metabolite components.
