Outline of Final Research Achievements

In this research, we have developed an accurate and high resolution imaging method for microwave ultrawideband bio-medical diagnosis or treatment especially for breast cancer. In particular, we extended the range points migration method for heterogeneous and dispersive breast media, and achieved a high accuracy for shape reconstruction, compared with that obtained by synthetic aperture based method. In addition, for microwave monitoring scheme of microwave based ablation treatment for cancer, we have developed the real-time, accurate and noise-robust imaging algorithm based on time difference of flight (TDOA) approach. We have demonstrated the effectiveness of our proposed method using the numerical simulation based testbed derived from MRI-based accurate numerical phantom.
