Abstract According to new sensitivity normalizations of electrical impedance and electrical capacitance tomography, the irrationality of linear normalization of sensitivity matrix of electromagnetic tomography is proposed. The new sensitivity normalization model is established based on the analytical formula in electromagnetic tomography. The formula of the new sensitivity normalization is given. The normalization effect of new model is compared with the original. The new sensitivity normalization is applied to the image reconstruction, and evaluated the image quality using the criterion correlation. It is conclusion that the new sensitivity normalization model is more close to the original trend and got higher reconstruction image quality.
