In this paper the capabilities of optical tomography (OT) applied to breast cancer detection have been discussed. The first step toward the creation of the forward problem solution. For this purpose BEM with isoparametric triangle element has been implemented, which improves the soIution accuracy. The forward problem solution in OT is based on the solution of diffusion equations in the frequency domain...
The main aim of the paper is to present a multi-region BEM with quadratic interpolation function for the flat, triangular surface elements and also an efficient method based on the inverse mapping with the aid of the Neural Network (NN) and Principal Component Analysis (PCA). The identification of the location and size of the anomalies as the core of the inverse problem solution, is considered. An...
