The aim of this paper is to clarify the treatable distance of Ferromagnetic Implant with Low Curie Temperature (FILCT), superparamagnetic nanoparticles Resovist ® (Resovist) and the mixture of FILCT and Resovist (Reso-FILCT) as heating elements by using a wireless temperature measurement induction heating system for hyperthermia under a constant temperature environment of 37℃. In this experiment, a high-frequency magnetic field was applied to the three heating elements and their temperature and the superimposed voltage were measured every 1.0 cm up to 6.0 cm until the temperature of heating element no longer exceeds 45℃ even after 300 seconds passed. As a result, it was clarified that the treatable distance of FILCT is within 1.0 cm, the temperature of Resovist is difficult to control, and the treatable distance of Reso-FILCT is within 5.0 cm. Furthermore, it was revealed that Reso-FILCT has an initial temperature rising rate of 3.6 times and a change in superimposed voltage of 1.28 times than that of FILCT. From this point, we considered that wireless temperature measurement induction heating system using Reso-FILCT as heating element is useful for clinical application.
