Boundary element modeling and simulation of biothermomechanical behavior in anisotropic laser-induced tissue hyperthermia

摘要

The main aim of this article is to propose a novel boundary element model for describing thermomechanical interactions in anisotropic laser-induced tissue hyperthermia. The two-dimensional governing equations are studied based on the thermal wave model of bioheat transfer (TWMBT) and Biot's theory. These uncoupled governing equations are solved independently using the boundary element method (BEM), which is a versatile and powerful method because it is dealing with more complex shapes of soft tissues and not needing the discretization of the internal domain, also, it has low RAM and CPU usage. Two numerical examples for square and elliptical cylinder tissues are solved to demonstrate the validity, efficiency and accuracy of the proposed model.
