Abstract

In this paper, we present a new thermo therapy of tumor control algorithm, in which a self-regulation factor is adopted to realize real-time temperature control with high-precision fuzzy controller. This method can not only realize the real-time control with ignoring influence of impedance parameters, but also enhance the stability and dynamic characteristics of the control system, and the performance of the radio-frequency thermo therapeutic equipment is enhanced. We have demonstrated this strategy is feasible and effective based on the experiment researches of liver tumor thermo therapy.
