要約(英語): Resonant circuit is expected to be used as heating source for hyperthermia implants because it can be effectively heated by an applied AC magnetic field. It was previously reported that the size of the implant was successfully miniaturized down to 0.9mm in diameter, which was less than the diameters of the 18G injection needle and catheter. However, after the implant is delivered in vivo, the temperature measurement of the implant is difficult. In order to realize a less-invasive treatment of cancer, the implant should have the capability to control its heating. The two types of resonant-circuit implants were prepared. A method to control the heating of the implant using a ferrite core is discussed in this paper.
