Abstract

The paper presents an extensive discussion on Microwave Imaging (MI) for breast cancer detection. Breast cancer has become a major cause of death among women worldwide, this makes the early detection of the cancerous tumor very essential in providing a rapid and effective treatment. Microwave Breast Imaging (MBI) is an emerging technique which is non-ionizing, non-invasive, safer and cheaper in comparison to the conventional techniques. It uses microwave radiation to generate an internal image of the breast which shows the tumor embedded in the breast layers. The paper begins with introducing the basic working principles of MBI and its types, anatomy of the breast, and the differences found in the dielectric properties of normal and malignant tissues. Active type of MBI – tomography and radar-based imaging are mainly covered in this paper. The most important part of active microwave imaging, i.e. antennas used for scanning the breast are also discussed. Moreover, numerical, experimental as well as clinical studies performed over the years are highlighted. In the end, challenges in the current techniques and future prospective of MBI are presented. Overall, this review paper provides a comprehensive insight on the techniques used in MBI, and the state-of-the-art research done in it.
