Abstract
Microwave image reconstruction is an ill-posed problem. Regularization methods are used to remove the ill-posed answers. However, the regularization methods are often problem independent and have smoothing effects. In this chapter, a novel problem-dependent regularization approach is introduced for the application of breast imaging that exploits a priori information for regularization. A real genetic algorithm (RGA) minimzes a cost functional that is essentially the error between the recorded and simulated data. At each iteration of the RGA, a neural network classifier rejects the solutions that cannot be a map of the dielectric properties of a breast. Although the application presented in this chapter is specific to breast cancer, the idea of using a priori information along with the classification techniques can be generally applied to the scenarios where information about the dielectric properties of the medium exists.
