Abstract
Image reconstruction in Electrical Impedance Tomography (EIT) is an ill-conditioned minimization problem. Here, the authors examine the utility of an esophageal reference electrode to improve EIT images. In a computer simulation, a reconstruction scheme utilizing an esophageal electrode outperformed two configurations relying entirely on boundary voltages in terms of both reconstruction error and speed of execution
