Spatial average conductivity 〈σ〉 by EIT. (a)~(e) Reconstructed 〈σ〉All of all sensor area, normalized average \(\:{OR}_{\text{A}\text{V}\text{G}}^{\text{n}\text{o}\text{r}\text{m}}\), and probabilistic air bubble cluster \(\:{\langle{u}_{2}\rangle}_{\text{A}\text{L}\text{L}}^{\:}\) of all sensor area of MF25, MF 35, MF40, MF 43 and MF47 over time. (f) Comparison of 〈σ〉All and \(\:{\langle{u}_{2}\rangle}_{\text{A}\text{l}\text{l}}\) over time.
