Noise Infuence of Magnetic Field to Conductivity Image Reconstruction
Original language description
The paper presents a conductivity calculation from values of the magnetic flux density measured outside the specimen. There is described the analysis of the noise influence that is presented in the measured values of a magnetic field. A conductivity calculation is based on the electrical impedance tomography (EIT) algorithm. The standard EIT exploited measured voltage values on electrodes placed at specimen boundaries to a conductivity calculation. The direct current source or the low frequency currentsource is connected to a specimen. A conductivity calculation is based on a minimizing of a suitable objective function. The least squares method is very often used for a minimization of an objective function. The Tikhonov regularization method is used in order to ensure the stability of an algorithm. The stability and the accuracy are dependent on an accuracy of measured voltage values.
