Outline of Final Research Achievements

Recently, the use of a ferromagnetic material in a soft-heating method has garnered much attention as a novel method for cancer treatment. By concurrently using this material as a thermal probe, we are currently developing a minimally-invasive heating and wireless temperature measurement system. We have found that by adjusting the distance between the heating coil and the material while maintaining a constant current flow in heating coil, the drift problem, which generated just after power is supplied during the on/off operation, did not occur any longer. Accordingly, it was not required the use of multi-sensors to reduce the drift, thereby minimizing costly. This study verified the validity of our wireless thermometry approach while performing rotary scanning and proposed a technique for determining achievement of target temperature. This knowledge complements other approaches for cancer treatment utilizing hyperthermia.
