The effect of small-scale mammary glands structure on the distribution of the deep temperature using the microwave radiometry diagnostics

The role of complex small-scale structure of the breast in the formation of the temperature distribution due to the strong spatial inhomogeneity of the thermal conductivity and specific heat of various biological components is discussed. Spatial variations in dielectric permittivity and conductivity in biological tissue can significantly affect the brightness temperature of tissues under the antenna. The effectiveness of diagnosis of tumors at an early stage can be improved by moving beyond multi-layer model to the simulation of multicomponent biological tissues with the fine structure and heterogeneous parameters (conductivity, moisture content, specific heat, conductivity, dielectric constant and specific heat).
