Noninvasive temperature measurement method for hyperthermia treatment using ferromagnetic implant with low curie temperature.
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.
