Application of the Log-Phase Formulation for Three-Dimensional Microwave Imaging

The performance of a three-dimensional reconstruction algorithm for microwave breast cancer detection is compared with that of a two-dimensional reconstruction algorithm. Both algorithms are based on inverse scattering and the configuration of the imaging system is the same in both cases. In the imaging system, data is collected at seven different planes and it is found that by combining the data from these seven planes, and performing the reconstruction for the entire three-dimensional imaging domain, better results are obtained than when the two-dimensional algorithm is applied for reconstructing each of the planes separately.
