Electrical Properties Tomography (EPT) is a promising technique to provide high specificity in breast cancer diagnosis. Previous studies have demonstrated that multi-transmit coils array enables reconstruction of the electrical properties free of transmit phase and local homogeneity assumptions. In this study, the strengths and drawbacks of a microstrip array and a loop array for EPT reconstruction in the breast at 3T were investigated based on numerical simulations. It has been discovered that with the same driving power, a loop array provides higher signal to noise ratio on the reconstructed image while a microstrip array performs better at delineating tissue boundaries.
