Abstract

This paper is focused on the estimation of the internal temperature of the breast, during the hyperthermia treatment of a tumor with the water-filtered infra-red-A technique. The internal temperatures are estimated as a solution of a state estimation problem, by using only nonintrusive surface measurements at the skin surface. Due to the nonlinear character of the problem, the state estimation problem is solved with the Particle Filter method, which is a sequential Monte-Carlo Bayesian technique. Results obtained with uncertainties in the measurements and in the mathematical formulation of the coupled radiation-bioheat transfer problem reveal the accuracy of the technique used in this work. The internal breast temperatures estimated with the particle filter method can be used in control strategies of the hyperthermia treatment of cancer, without intrusive temperature sensors that cause patient discomfort.
