Abstract

Selection of ferrite powder and suitable frequency were carried out to realize a thermal coagulation technique in which tumors are locally heated to 60-80℃ by an application of alternating magnetic field from external coils after they are stuffed with ferrite powder. Various ferrite powders were heated by an alternating magnetic field in 80kHz-399kHz. In this frequency range, the largest increase in temperature (ΔT) was obtained for the MgFe_2O_4 in all the samples examined. The ΔT value was almost proportional to the applied power and the weight of the powder. The heating ability for the Mg-ferrite was ca. 86 J・min^<-1>・g^<-1> under AC magnetic field (200W, 370kHz).
