Improved Anomaly Characterization in Biological Tissues Through Relative Permittivity Estimation

2024 46th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)
Microwave imaging for biomedical applications still suffers from imprecise reconstruction of the relative permittivity (εr) of tissues. Most of the traditional methods employing qualitative measures find it difficult to simultaneously estimate the location and size of the anomaly. This work presents a novel two step approach for improving the detection
