Abstract :
Non-invasive hyperthermic ablation technique of adipose tissue under skin using microwave is proposed, which exploits dielectric heating to heat up the adipose tissue using a circular antenna. We select an operating frequency 5.8 GHz, ISM band, for concentrating EM power radiated from the external antenna to the adipose tissue and for minimizing it to inner organs of the body. In order to protect skin from heat, a cooling system used a fan, which bring wind to it, is developed. And using obese rats, an experiment was performed to validate the proposed non-invasive hyperthermic ablation technique. We show that weight of each obese rats applied the proposed system was reduced.
