title: Noninvasive temperature measurement method for hyperthermia treatment using ferromagnetic implant with low curie temperature.
abstract: Induction heating using 'ferromagnetic implant with low Curie temperature (FILCT)' is one of the heating methods for hyperthermia. However, a lot of energy is needed to heat malignant tumors; the heating efficiency has to be improved. In order to address this problem, we propose using FILCT as a probe for temperature. A non-invasive temperature measurement system was developed based on this approach. A key advantage of this system is that it can noninvasively distinguish whether the temperature of FILCT has reached the Curie temperature or not. As a result, materials with high heating efficiency may be used.
