Abstract

It is important to measure the temperature of magnetic nanoparticles during hyperthermia therapy to develop safe practices. We theoretically demonstrate a method for measuring the temperature of magnetic nanoparticles using induction coils and nanoparticle magnetization harmonics. A geometrically decoupled sensing coil is described that enhances the sensitivity to small amounts of iron and also could possibly be used to eliminate sensing challenges created by the high-powered hyperthermia drive field.
