The
distribution of magnetic fields can be tailored using high dielectric
materials. Here, we introduce a new material with high and tunable dielectric
constant, and also low background MRI signal. The material is based upon
metal titanates, which can be made into a geometrically-formable slurry by
combining with deionized water. Results obtained at 7 Tesla show a
significant increase in image intensity in areas such as the temporal lobe
and base of the brain.
