摘要：

In order to realize a thermal coagulation technique in which tumors are locally heated up to 60-80 degreesC by inductive heating and necrotized, selection of ferrite powder and frequency are performed. We investigate the heating properties by applying AC magnetic field for various ferrite powders (micrometer size of the particles). The temperature rise for Mg-ferrite (MgFe2O4) powder is the largest around 360 kHz in our samples. It has sufficient heating ability for thermal coagulation therapy against cancer.
