Reconstructed proton density and its effect on the accuracy of EP reconstruction using the gradient-based EPT (gEPT) algorithm in a phantom-mimicking simulation study. Images in each column represent (a–c) target maps of ρ, conductivity (σ) and permittivity (ε), (d–f) reconstruction of ρ based on the proposed method, and reconstructions of σ and ε using gEPT algorithm and the reconstructed ρ in (d), (g–i) reconstruction of ρ assuming identical B1 summation pattern, and reconstruction of σ and ε using gEPT algorithm and the estimated ρ in (g). The symbol “*” indicates seed points. The axis unit is cm.
