| Abstract: | To realize temperature real-time control in microwave heat treatment, this paper presents a new type of thermal dosimeter on hyperthermia. The sign of temperature is extracted by mini-thermal-electronic-couple transducer, amplification circuit and main magnifier. The bond of temperature controlling and thermal therapy is achieved, the experimental prototype of thermal dosimeter equipment is developed and clinical experiment scheme is designed. The whole system is simple in structure, high in efficiency and reliability. |
