THERMOPHYSICAL INTRAOPERATIONAL ESTIMATES FOR THE DESTRUCTION ZONE OF TUMOR TISSUE IN INTERSTITIAL THERMOTHERAPY
V. N. Bidnenko and V. L. Sigal UDC 576.8.06+616.006.097+616.33.002.44 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.
