Reconstructed proton density and its effect on the accuracy of EP reconstruction using the gradient-based EPT (gEPT) algorithm. Top: reconstructed proton density using the proposed method (a), assuming symmetric B1 pattern (b) or assuming identical B1 pattern (c). Middle: reconstructed conductivity (d)–(f) using gEPT algorithm and estimated proton density corresponding to (a)–(c), respectively. Bottom: reconstructed permittivity (g)–(i) using gEPT algorithm and estimated proton density corresponding to (a)–(c), respectively. The axis unit is cm.
