Figures & data
Fig. 1 The sensing head.
Fig. 2 Layout of the electrode array of the Mainz EIT device. The small circles labelled from 1 to 12 show the outer electrodes for current injection. The position of the 54 inner electrodes for potential measurements are drawn as thick points. The network is used as a model of the measurement area. The positions 1, 2 and 3 indicate the places above the sensing head where metallic objects were immersed in conducting liquid, while the positions 4 and 5 indicate the places where an agar phantom was placed.
Fig. 3 Conductivity reconstructions for the agar phantom placed at position 5 and at different distances below the sensing head: (a) and (c) 2 mm; (b) and (d) 5 mm. (a) and (b): cross-sections of conductivity reconstructions; (c) and (d): three-dimensional views of the conductivity reconstructions.
Fig. 4 Cross-sections of conductivity reconstruction for M15 at position 1 and M20 at position 2. The inclusion is (a) 2 mm and (b) 5 mm below the sensing head.
Fig. 5 Cross-sections of conductivity reconstruction for M15 at position 2 and M20 at position 1. The inclusion is (a) 2 mm and (b) 5 mm below the sensing head.
Fig. 6 Cross-sections of conductivity reconstruction for M15 at position 1 and M20 at position 3. The inclusion is (a) 2mm and (b) 5 mm below the sensing head.
