Two-dimensional computer analysis of a microwave flat antenna array for breast cancer tomography

In this paper, we report a two-dimensional computer simulation of a microwa ve Oat antenna array for breast cancer tomography. This new technology prom ises reduction of X-ray exposure and easier access to peripheral areas of t he breast. Using our version of the Newton algorithm, we studied two simple mathematical objects and a more sophisticated two-dimensional model of the breast that takes into account dielectrical properties of different human tissues and malignant tumors. Our calculations show that, operating at 2 GH z, this device may give very reasonable images of tissues located up to 3-4 cm beneath the surface.
