Microwave imaging system for early detection of breast cancer

Breast cancer is the most common cancer among females, and one of the leading causes of death worldwide. Nowadays, the most common method for breast cancer detection is X-ray mammogram screening. Since mammography employs ionizing radiations, the repetition of exposure is not recommended. Aiming to overcome this limitation of the X-ray mammogram screening, a new, low-cost and safe microwave imaging technique was developed in this study. The proposed technique depends on the significant contrast in the dielectric properties of the normal and the tumor tissues. The Computer Simulation Technology Microwave Studio was used to create a model of breast with tumor of 5mm radius. And a circular patch antenna was used in this study. The breast model was placed in front of the antenna, which used as a transmitter as well as a receiver of the microwave. The reflected waves were processed in order to form an image of the tumor. The reconstruction of the reflected waves permits a clear identification of the tumor.
