Heat Source power Estimation for Therapeutic Hyperthermia Treatment of Breast Tumor Using Inverse Method
Determination of temprature distribution is a critical factor in thermal treatment of diseased organs such as cancerous tumors. In this paper is, the optimal power of the heat source is estimated in order to destroy cancer cells due to the temperature distribution in the cancerous tissue. The geometry of breast is represented as a hemisphere containing three layers, muscle, gland and fat. The conjugate gradient method is used to solve the inverse heat conduction problem using Pennes bioheat equation in the axisymmetric coordinate system.To make the solve of the problem easier, the irregular region in the physical domain (r,z ) is transformed into a rectangle in the computational domain (ξ , η).
