Multifrequency Electrical Impedance Tomography Using Spectral Constraints

Abstract: Multifrequency electrical impedance tomography (MFEIT) exploits the dependence of tissue impedance on frequency to recover an image of conductivity. MFEIT could provide emergency diagnosis of pathologies such as acute stroke, brain injury and breast cancer. We present a method for performing MFEIT using spectral constraints. Boundary voltage data is employed directly to reconstruct the volume fraction distribution of component tissues using a nonlinear method. Given that the reconstructed parameter is frequenc… Show more

“…WFD has been proven that it can reconstruct a perturbation in a frequency variant background (Seo et al, 2008, Jun et al, 2009a, Ahn et al, 2011, but as a linear algorithm its application is restricted by the availability of linearised approximation (Jun et al, 2009). For example, WFD cannot reconstruct proper images if the area of perturbation is too large (Malone et al, 2014b). A method for performing MFEIT using Spectral Constraints (MFEITSC) was proposed by Malone et al, (2014bMalone et al, ( , 2014a.…”

The inverse problem was modified by substituting the conductivity with the volume fraction of each tissue in each voxel, describing the physical distribution of tissues in the domain.…”
