The paper presents the results of mathematical modeling of the anisotropy of specific electric conductivity of soft biological tissue and investigates the difference between the results of the process of welding biological tissues produced without and taking into account the anisotropy of the specific electric conductivity of a biological tissue. The results of calculations of tissue resistance, current density and impedance dispersion are compared. 14 Ref., 1 Tabl., 10 Fig.
Keywords: welding of biological tissues, specific electric conductivity, mathematical modeling, anisotropy of biological tissues
