A mathematical modeling was adopted to calculate the ferric ion diffusion coefficient based on the radiation induced magnetic resonance (MR) image intensity change in Fricke-agarose gels. A fast magnetic resonance imaging acquisition technique was employed to avoid the smearing of acquired data due to diffusion over an extended period of time. Our results showed that for a Fricke-agarose gel contained 1mM ammonium ferrous sulfate, 1% agarose. 1mM sodium chloride and 50mM sulfuric acid, its ferric ion diffusion coefficient is 1.31×10-2cm-2h-1 in room temperature. This value falls within the 1 ∼ 2×10-2cm2h-1 range obtained by previous studies under varying concentrations of gel ingredients.
