Computational Research of Internal Temperature Distribution for Liver Tissues under Laser Irradiation

Abstract:

To study the effect of blood perfusion rate and air convection boundary condition upon heat transfer of liver tissues by establishing heat conduction model of liver tissues under laser irradiation.The analytical solution of the model was solved by homogenizing boundary condition and the numerical solution of the bio-heat transfer model under the two-dimensional cylindrical coordinate was calculated by the Finite Element Method (FEM).The results show that the highest temperature irradiated by laser is on the center point of the surface tissue, and decreases in the radial and axial direction, the temperature in the axial degrades more seriously than that in the radial.This study provides a theoretic bases for laser applications in medicine.
