Using EIDORS to image lungs

2D EIT for lung imaging

Use mk_common_model to create a thorax shaped model with 16 electrodes. Ensure the model uses 1) Correct stimulation patterns (adjacent is default), 2) Normalized difference imaging

Figure: 2D FEM of thorax (units in mm). Electrode #1 (o) and electrode #2 (o) are shown in different colours than the others (o).
Electrodes in the FEM must match those on the subject. This example shows two possible repositioning of electrodes

Figure: Left: electrodes placed counter-clockwise starting at 12 O'clock. Right: electrodes placed clockwise starting at 6 O'clock (on the dorsal side)

Figure: Lung image slices (frame rate of 1/7 seconds). Image progression is from left to right, top to bottom. One breath is shows. There also appears to be a movement of blood dorsally during the cardiac cycle.
