)>IJH=?J - Electrical Impedance Tomography (EIT) uses
electrical measurements at electrodes placed on the
thorax to image changes in the conductivity distribution
within the thorax. This technique should be of interest in
studying pulmonary edema as the clinical phenomena of
interest induce large conductivity changes. We have
conducted a series of experiments on dogs to quantify the
capacity of EIT to measure lung tidal volume and fluid
content. Results indicate good correlation of the quantities
measured by EIT with standard reference techniques.
