Radar Imaging Using Bilateral Symmetry of Breast Tissue

A radar imaging method is proposed for early cancer detection using difference between the radar response of the left and right breasts. In this study, only the glandular tissue was taken from MRI images of several breast cancer patients, and the bilateral symmetry of the mammary gland structure was quantitatively evaluated. Even in cancer patients, the correlation between right and left glandular tissue showed high values of 0.71 to 0.88. Based on this fact, the backscattering caused by cancer is revealed by radar imaging using the difference between the radar response of the right and left breasts. This method is effective even in a lower band than the conventional ultra-wideband method. Since the same equipment can be used for tomography, the proposed method is a strong alternative method for early breast cancer detection.
