On the Forward Scattering of Microwave Breast Imaging

الملخص EN

Microwave imaging for breast cancer detection has been of significant interest for the last two decades.

Recent studies focus on solving the imaging problem using an inverse scattering approach.

Efforts have mainly been focused on the development of the inverse scattering algorithms, experimental setup, antenna design and clinical trials.

However, the success of microwave breast imaging also heavily relies on the quality of the forward data such that the tumor inside the breast volume is well illuminated.

In this work, a numerical study of the forward scattering data is conducted.

The scattering behavior of simple breast models under different polarization states and aspect angles of illumination are considered.

Numerical results have demonstrated that better data contrast could be obtained when the breast volume is illuminated using cross-polarized components in linear polarization basis or the copolarized components in the circular polarization basis.
