Density ratios among the nine fat proton components were measured for optimizing image processing in fat-water thermometry based on methylene T1 and water proton resonance frequency. The results suggested that the relative ratios among the components were mostly temperature independent suggesting that the component ratios can be fixed in the fat signal estimation in temperature imaging.
