To relieve the load to human body accompanied by the cancer treatment, hyperthermia to decrease or curative excision for the cancer cell using the radio frequency (RF) electromagnetic wave is investigated. The hyperthermia in the cancer treatment is a method of the hearting cell. The conductive or magnetic material insert in the cancer cell. The RF electromagnetic wave is applied from RF coil. In this study, as the hyperthermia technology produced an increase in temperature to cancer cell effectively is to develop, the magnetic field distribution in the RF coil are analyzed and measured. When the Gaussian pulse which has wide frequency band is applied in the birdcage coil, the magnetic field in the birdcage coil is appeared the resonance frequency of the birdcage coil. The magnetic field Hz in the birdcage coil by the analysis is the largest. The distribution of the magnetic field is the uniform within 7dB. The frequency of the largest of the magnetic field by the measurement is 3 to 4MHz less than that of the analysis. The magnetic field of the largest by the measurement is 18 to 21dB less than that of the analysis. |
