Abstract :
Electrical impedance tomography is an imaging technique used to estimate the electrical conductivity distribution of human body sections. To solve the inverse problem of EIT many numerical methods have been developed. Two of these methods, namely the backprojection algorithm and the sensitivity method, are compared in this paper on some canonical models representing a section of the human body.
