电特性层析成像(EPT)通过磁共振成像(MRI)从射频(RF)磁场中非侵入性地重建人体的电特性(EP)。虽然我们以前提出的EPT方法稳定地获得了EP分布，但由于忽略了不可测量的磁场分量，导致了EP重建的误差。这项研究提出了一种新的方法来估计不可测量的磁场，并将其应用于我们之前报道的EPT方法。由数值模拟和实验模型得到的结果表明，提出的不可测磁场估计抑制了EP误差。
Electrical properties tomography (EPT) noninvasively reconstructs electrical properties (EPs) in human bodies from the radio-frequency (RF) magnetic field with magnetic resonance imaging (MRI). Although our previously proposed EPT method stably obtained EP distributions, EP reconstruction errors occurred because the unmeasurable magnetic field components were ignored. This study proposes a novel method to estimate the unmeasurable magnetic fields and to apply it to our previously reported EPT method. The results obtained from a numerical simulation and an experimental phantom indicate that the proposed estimation of the unmeasurable magnetic fields suppresses EP errors.
