Summary:
The Hyperthermia treatment system has been regarded as an effective treatment for tumor cells as the efficacy and safety of it is proved. The effect of treatment can be enhanced when chemotherapy and radiation oncology are performed with heated tumor cell by hyperthermia treatment system. The reconfigurable antenna operating frequencies of 433 MHz and 915 MHz for effective use in the superficial hyperthermia system is proposed for the treatment of the tumor cells. The impedance matching with the lumped elements is also introduced. The temperature distributions are occurred different in targeted medium by the hyperthermia applicators which operate with different frequencies. Which the temperature distributions are formed differently can cause the various effect of the prescription compared with the applicator which induces the single distribution from the applicator with the single operating frequency. The effects of the proposed antenna are expected to apply the hyperthermia system at different frequencies selectively depending on the symptom of patients and improve the curative effect.
