Abstract
An apparatus and method for the early detection of breast cancer uses ultra-wideband, multi-angle microwave imaging. The apparatus includes a matched dielectric layer and a conformal antenna array with antenna elements arranged in a hemispherical pattern. The method achieves high resolution and a high signal-to-clutter ratio by employing synthetic focusing (SF) and special clutter rejection (SCR) algorithms. The improved performance of the method is experimentally demonstrated using a realistic, heterogeneous breast phantom composed of materials with dielectric properties closely matched to those of skin, fat, glandular, and tumorous breast tissue.
