Abstract

Cancer is the most-prominent disease that causes death. Most of the cancer therapy aims at to raise the temperature of the cancerous tissue above a therapeutic value and thermally kill or destroy it. One of the main concerns of these therapies is to minimize damage of the healthy cells surrounded in infected cell. Precise acknowledgement of temperature profile of living tissue during therapy is utmost necessary for this purpose. Keeping that necessity in mind, this paper presents an unsteady finite element model of the bio heat equation to analyse the temperature distribution during the therapy. Crank-Nicolson method has been used for the time discretization of the unsteady part of the problem. And using this method we investigate thermal behaviours in biological tissues subjected to constant, sinusoidal spatial and surface, point and stochastic heating. Result describe in this paper could be useful for researchers and doctors to optimize the treatment procedure even protocols.
