Table 1. PE and |ΔRES| errors obtained for EIT simulations with different methods.

Method	PE (%)	|ΔRES| (%)	SD (%)
One-step GN	12.44%	11.07%	19.63%
PDIPM	20.81%	19.91%	25.77%
ANN as inverse solver	8.80%	4.01%	22.90%
One-step GN + ANN	1.66%	3.70%	16.18%

Corresponding images can be seen in Fig 6. The proposed post-processing (one-step GN + ANN) gives the lowest errors.
