Abstract: In a CT image of a living body, contours of internal organs thereof are discriminated. Parameters are beforehand stored in a memory for a plurality of internal organs of the living body. Applicators are attached onto the living body and then a high frequency power is applied to electrodes disposed therein so as to heat an internal portion of the body. Based on an intensity of an electric field generated in the body due to the applied power and the parameters stored in the memory, a temperature distribution on the CT image is estimated. To retain an estimated temperature of an objective tumor at a predetermined target temperature, the high frequency power and the cooling water in the applicators are controlled. In the estimation of the temperature distribution, the parameters of the living body are repeatedly corrected to minimize a discrepancy between a temperature measured at a preset position and an estimated temperature associated therewith.

Abstract: A high frequency heat therapy system, comprising: an applicator equipped with an electrode and a bolus bag; a high frequency generator unit for generating high frequency electric current that is to be applied to the electrode; a therapeutic table for adjustably supporting a patient; an applicator support unit for adjustably applying the applicator to the patient; a therapeutic data input unit for specifying therapeutic data including those related to positioning of the therapeutic table and the applicator support unit; a therapeutic data storage unit for storing therapeutic data including the data on positioning of the therapeutic table and the applicator; a drive control unit for drivingly controlling the therapeutic table and the applicator support unit according to the data on positioning of the therapeutic table and the applicator stored in the storage unit; and a central control unit for transmitting data stored in the therapeutic data storage unit and, if any, the therapeutic data specified by the thera
