Studying the Boundary Data Profile of a Practical Phantom for Medical Electrical Impedance Tomography with Different Electrode Geometries

Boundary data profile of practical phantom is studied for two dimensional Medical Electrical Impedance Tomography using different electrode geometries. A sinusoidal current is injected to the phantom boundary for generating surface potential data using neighboring current injection protocol. Boundary data are collected for different electrode area and bathing solution heights using a common mode electrode with different diameters. Measured boundary potentials are compared with the simulated data generated by a finite element method based forward solver. Comparing the measured potential with simulated data it is intended to modify the phantom design parameters for better image reconstruction.
