Microwave imaging for breast cancer detection: Comparison of tomographic imaging algorithms using single-frequency and time-domain data

Still more research groups are promoting microwave imaging as a viable supplement or substitution to more conventional imaging modalities. A widespread approach for microwave imaging of the breast is tomographic imaging in which one seeks to reconstruct the distributions of permittivity and conductivity in the breast. In this paper two nonlinear tomographic algorithms are compared - one is a single-frequency algorithm and the other is a time-domain algorithm.
