Two areas are discussed in this article. The first area is the development of antennas dedicated to electromagnetic ablation. Antennas are important for radiating electromagnetic power to the ablated area with precision. The second area is the development of methods used for sensing the temperature of a localized biological tissue. This is vital to minimize damage to surrounding healthy tissues during an ablation procedure. Research is conducted in the area of temperature sensing methods to more efficiently detect thermal conductivity and diffusivity of biological tissues. Basically, in an ablation procedure, electromagnetic power is transformed into heat for ablation purposes. A description of a patented state-of-the-art microwave ablation system is given.
