Quantitative visualization of structure in freezing porous media via magnetic resonance imaging.

Summary

Full-field quantitative visualization of freezing interfaces requires the introduction of high resolution noninvasive methods. Magnetic resonance imaging (MRI) is a versatile tool for mapping the distribution of liquids (primarily water) in three-dimensional space, and is the only practical solution in systems that are strongly refracting or opaque to visible light. MRI is employed to visualize freezing in water-saturated packed beds consisting of spherical beads and cooled from below. Imaging of the stagnant interstitial water is accomplished by exploiting the strong contrast in MRI signal between interstital ice and liquid water.
