This study models the use of transcutaneous electrical nerve stimulation on skin with a disk electrode in order to simulate tissue damage. The current density distribution above a disk electrode is known to be a dynamic and non-uniform quantity that is intensified at the edges of the disk. The non-uniformity is subject to change through using various electrode geometries or stimulation methods....

The fundamental solution of the system of differential equations in bio-thermoelasticity with dual phase lag (DPL) in case of steady oscillations in terms of elementary function is constructed and basic property is established. The tissue is considered as an isotropic medium and the propagation of plane harmonic waves is studied. The Christoffel equations are obtained and modified with the ther...

This work aimed to elucidate the primary factors which affect skin temperature. A simple thermophysical model of skin, accounts for radiative, convective, and evaporative heat losses, has been developed address it. The is based on skin’s morphology consists passive (nonviable tissue) active (viable layers. bioheat equation was solved these layers using realistic assumptions. It found that other...

A comprehensive analysis of bioheat transport through a double layer and multilayer biological media is presented in this work. Analytical solutions have been developed for blood and tissue phase temperatures and overall heat exchange correlations, incorporating thermal conduction in tissue and vascular system, blood-tissue convective heat exchange, metabolic heat generation, and imposed heat f...

A series solution for a 2D bioheat Pennes conduction model with convective boundary conditions is established by using the classical Fourier method. To validate and compare results, a numerical method for constructing highly accurate numerical solutions is also derived and numerically illustrated. Both, the series solution and the proposed numerical method open interesting possibilities of appl...

Accurate and efficient prediction of soft tissue temperatures is essential to computer-assisted treatment systems for thermal ablation. It can be used predict ablation volumes personalised planning image-guided intervention. Numerically, it requires full nonlinear modelling the coupled computational bioheat transfer biomechanics, solution procedures; however, existing studies considered analysi...

A general three-dimensional bioheat equation for local tissue heat transfer has been derived with less assumptions, exploiting a volume averaging theory commonly used in fluid-saturated porous media. The volume averaged energy equations obtained for the arterial blood, venous blood and tissue were combined together to form a single energy equation in terms of the tissue temperature alone. The r...
