Mathematical modeling of temperature distribution in malignant tumors that are heterogeneous by blood stream

Abstract

The study of the thermal properties of tumors shows that blood perfusion as the most important biomechanical parameter corresponding to the conversion coefficient in the biothermal equation depends not only on the type of neoplasm, but is largely determined by its size, and is variable by section of the tumor. The heterogeneity of the thermal properties of tumors appears, apparently, for metabolic heat. Naturally, different values of the maximum intensity of the blood flow and the specific power of the thermal source acting on the tissue within one neoplasm lead to unequal values of other thermal coefficients entering into the biothermal equation.
