A simple point-wise formula for double excitation MREPT suitable for reconstructing boundaries

For MREPT, apart from various assumptions made for deriving algorithms, one of the major problem is still reconstructing the electrical properties (EP) at the tissue boundaries where gradients of these variables are high (non-constant region). In this study, we propose an easily implementable point-wise formula for reconstructing the EPs in all regions including transition regions. The algorithm is tested with noisy and noiseless simulation data and successful reconstructions are obtained. The proposed algorithm is also suitable for practically reconstructing EPs when transmit and/or receive arrays are used.
