In invasive techniques such as laser angioplasty and intravascular ultrasonography, there is a source of heat inside the vascular system that is being released/dissipated by the inserted device. In this article, the transfer of heat from this source to the plaque deposited on the walls of the artery has been studied numerically using two different models. The models consider the transient conduction and the absorption of heat through the plaque. The variation of thermophysical properties is also included in the analysis. It was found that the temperature distribution depends significantly on the type of plaque and the power level. heat transfer, arterial plaque
