Abstract

An attempt has been made to obtain a medical material applicable to the ablation therapy of liver cancer. The heating property of the needle-shaped Mg-ferrite (MgFe2O4) prepared using a sintering technique was studied under an external AC magnetic field at 370 kHz. The increase in temperature (ΔT) was as high as 32℃ for the stick of 1.5 mm in diameter, while the complementary use of these three sticks achieved marked ΔT enhancement of 58℃. In a rabbit liver, high-frequency inductive heating of the needle-shaped Mg-ferrite resulted in the local destruction of the tissue due to coagulative necrosis.
