摘      要：To improve microwave hyperthevmia in cancer therapy, the thermal effect of fer-rimagnetic resonance (FMR) during microwave irradiation was studied. Resonant temperatureelevation (RTE) of single crystal grain and polycrystal powder of resonant media was measuredalone and in imitative muscle and egg white and in mice. The results indicated that the RTE produced by FMR could be used to improve penetrationdeepness, heating selectivity and temperature distribution of microwave hyperthermia in cancertreatment. It was expected that the potential function of the FMR heating system would be ex-ploited greatly for cancer therapy, and then magnetically guided microwave hyperthermia thera-py, chemotherapy, radiotherapy and immunotherapy might he combined multiply within this sys-tem by means of the static magnetic field (SMF) and magnetic microcarrier. Limitation of reso-nant heating was also discussed in this paper.
