The Design and Realization of a New Normalization Algorithm in Electromagnetic Tomography

摘要

In this study, we introduce the new sensitivity normalizations of electrical impedance and electrical capacitance tomography. Moreover, in electromagnetic tomography, we proposed the irrationality of linear normalization of sensitivity matrix, thence the new sensitivity normalization model was established based on the analytical formula. The formula of the new sensitivity normalization was given. The normalization effect of new model was compared with the original one. The new sensitivity normalization was 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.
