Design of the Control System for Thermal Treatment via Fuzzy Logic PID
The combination of cryosurgery and hyperthermia treatment has been demonstrated to be more efficient to destroy tumor tissue.A cryosurgery-hyperthermia system is designed by our group.However,the precise control of the system is difficult due to the integration.In this paper,a novel control system is proposed to ensure that the thermal system works effectively.First,the tissue temperature around the probe is regulated and kept in a desired range when radio frequency ablation is operated.Second,precise control of temperature is achieved in hyperthermia treatment using fuzzy logic PID type controller.The results of ex vivo liver experiment demonstrate that this system could provide a rather good performance with the proposed control method.
