According to ex-vivo study, breast tumor has higher conductivity value than normal breast tissue. As based on the research, breast conductivity imaging was attempted using phase-based electrical property tomography (EPT). However, to use phase-based EPT, the spatial variation of the magnitude of receive field (B1-) have to be negligible. In this study, using the transceive phase with zero-order phase combine, the error in conductivity map was minimized and the method was also applied to patient's breast data.
