Research on the hyperthermia-therapy performances of invasive microwave antennas / 中国医疗器械杂志

ABSTRACT

The paper introduces four kinds of 2450 MHz antennas including noninsulted (bare), insulated-open-tip (I.O.T.), dipole-type and sleeve invasive microwave ones. The comparison between the antennas' hyperthermia performances in the muscle tissue phantom made by specific absorption rate (SAR) shows that the sleeve antenna is the best. It has a bigger heating range and a changeless shape and is independent of the inserting depth.
