Abstract: For inverse reconstruction of temperature fields in bio -heat transfer control, it is very important to estimate the parameters, such as thermal conductivity K, blood perfusion rate Wb etc. In bio -heat transfer Pennes equation. A new method of parameter identification by means of the genetic algorithm is proposed in this paper to carry out inverse reconstruction of temperature fields. The application of this method to the model of hyperthermia is also suggested.

Key words: genetic algorithm, bio-heat transfer equation, hyperthermia
