Abstract: Time series prediction approach is utilized in this paper to predict and analyze the law governing the change of temperature somewhere inside the tumor. The radial power and the marginal temperature of the interface between the probe and the tumor are modified, and the temperature of the body of tumor is controlled according to the result of the prediction in order to achieve the desired curative effect.

Key words: prediction model of ARMA (n,m), tumor, hyperthermia treatment, numerical analysis
