Research Abstract

We performed a fundamental experiment of heating effect about nano-magnetic fluid in magnetic resonance imaging scanner with high magnetic field. The heating effects seen in the peripheral gantry group were higher than the central gantry group. Those results were thought to be derived from dielectric heating.
