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.
