Claim 10:
11. The method of claim 1, wherein the fitting is carried out with each of the 129Xe RBC resonance, the 129Xe barrier resonance and the 129Xe gas-phase resonance characterized by 4 spectral parameters: amplitude (α), frequency (ƒ), phase (φ), and Lorentzian linewidth (FWHM), and, for the barrier resonance, a 5th parameter, a Gaussian linewidth (FWHMG), is also extracted, and wherein the fitting is carried out with the barrier resonance initialized with respective initial Lorentzian and Gaussian linewidths, and wherein the fitting is carried out using the below equation:, s
