Equal-voltage curves if the phantom includes heterogeneities

Visualization of surface conductivity distributions of tomography cross-section using conductivity zones method

Irina A. Sushko

Abstract


Conductivity zones method is suggested that allows reconstructing the image of electrical impedance tomography with essentially lower computation expenses. Results of reconstruction performed by regularizing the matrix of contour-edge voltage derivatives with respect to zones’ surface conductivities.
