Fig. 1
The sensor design based on a 5 by 5 planar coil matrix.
Fig. 2
The normalized spectrum of the sigular values. The exponential decay illustrates the ill-posedness of the image reconstruction.
Fig. 3
The realistic chest model and the coil arranegement used in simulations. Red regions within the lungs represent the fluid accumulation, i.e., edema formation regions, due to gravity.
Fig. 4
The spatial sensitivity distribution of difirent transmit-receive coil pairs in the sensor matrix.
Fig. 5
The PSFs of several locations corresponding to the SNR level of 60 dB.
Fig. 6
The transverse plane (i.e., imaging plane) of the chest model. The color contrasts of blue in the lung regions represent the levels of edetamous lung injury at 2.5 cm, 5 cm and 7.5 cm.
Fig. 7
The reconstructed images due to the temporal conductivity changes during ventilation for diffenrent SNR levels. The slices correspond to the imaging plane.
Fig. 8
The left column shows the lung function with different levels of lung collapse occured in both lungs simultaneously. The middle and right columns represent, respectively, the cases that the collapse occured in the left lung and right lung only. The rows denote different levels of lung injury.
Fig. 9
Image reconstructions of the edematous region for different levels of collapse. The rows denote different levels of lung injury.
Fig. 10
The normalized edema reconstructions along the ventral to dorsal oriented line passing through the peak value of the reconstructions
Fig. 11
Possible reconstructions that may be caused by different distorsions are illustrated. The rows denote, respectively, the images reconstructed from different body distorsions, i.e., 10% chest expansion, 10o clockwise rotation and 2 cm right-lateral displacement.
