Abstract
The aim of this work is to estimate the location and intensity of a heat source (tumor) within a tissue from surface temperatures using specified sequential function method. First, the 1D bioheat equation is solved analytically using Green’s Functions method. Then, sequential method is used for the estimation of tumor heat generation and the Pearson correlation coefficient is used to determine the location of the heat source. Numerical results obtained from simulated temperatures in the commercial software COMSOL were accurate, i.e., the location and intensity of the tumor were estimated with errors less than 0.1%. Experimental results using a phantom tissue were satisfactory, i.e., the location and intensity of the tumor were estimated with errors less than 10%.
