Keywords:
Breast cancer imaging, heterogeneous and dispersive breast tissue, inverse scattering problem, microwave tomography, penetration depth for different breast typesAbstract
The robustness of the microwave tomography method based on frequency dependent finite difference time domain numerical method and hybrid genetic algorithm for breast cancer imaging for different levels of noise are investigated in this paper. These results indicate the algorithm performs well in the case of data contaminated by various levels of additive white Gaussian noise (up to 15 % of signal strength). Noise levels above this value inhibit the efficacy of the method.
