THERMOPHYSICAL INTRAOPERATIONAL ESTIMATES FOR 
THE DESTRUCTION ZONE OF TUMOR TISSUE
IN INTERSTITIAL THERMOTHERAPY

The authors developed models of intraoperational selection 
of the optimum regime for realization of thermotherapy of tumors and 
determination of the degree of their destruction based on successive 
fixation of the times of relaxation of their temperature to the arterial 
one. The models and evaluations of such times are based on the proposed 
mechanism of destruction of a tumor in local heating that is reduced 
to thermal regimes ensuring minimization, up to cessation, of the 
blood flow in the tissue, which causes its subsequent self-destruction.
