CEN Lecture Series | Mammography using Microwaves: Is it possible? (February 2023)
This work proposes the use of a breast screening modality that is highly similar to X-ray mammography but using low-power non-ionizing microwaves. Specifically, instead of the X-ray film, a metasurface film is used to capture an impression of the breast when illuminated by a low-power non-ionizing microwaves source. The fundamental principle of this technique relies on using a metasurface structure as a sheet to absorb the transmitted electromagnetic energy through the breast. An image that correlates to the composition of the breast is reconstructed by recording the microwaves power impression on the metasurface. Numerical experiments were carried out on numerical breast phantom, demonstrating the viability of the proposed method. The advantages of this new imaging modality is that it provides benign non-invasive breast screening for women at a cost significantly lower than traditional screening modalities such as CT Scan, MRI and X-ray mammography.
