Fig. 10From: A novel time-difference electrical impedance tomography algorithm using multi-frequency informationThree-tissue case model and reconstruction: a numerical model. Reconstructed images of different interested tissues under b SNR = 60 dB, c SNR = 80 dB. For each image, the color bar represents the range of the conductivity change, and the numbers represent the maximum range of change. The unit is S/mBack to article page
