要約(英語): Hyperthermia is a cancer treatment, in which tumors are heated. We proposed hyperthermia treatment using heat dissipation from magnetic nanoparticles under an AC magnetic field applied by a pancake-type applicator. The excitation condition satisfies the reported guideline, defined by the influence that electromagnetic fields affect the human body. The applicator can form a sufficient AC magnetic field deep in the human body, which can excite the magnetic nanoparticles that have been injected into the tumor tissue, as long as the tumor diameter is greater than 10 mm. This will generate specific loss power of 37 kW/kg and heat the tumor tissue by 5 K, as required for hyperthermia treatment.
