Modeling and Measuring of the Changes of the Magnetic Field Next to Non-Ferromagnetic Substances for Magnetic Susceptibility Calculation
Original language description
This article is focused on the principles of the magnetic susceptibility measurement of the non-ferromagnetic substances using NMR tomography. Magnetic susceptibility is calculated from changes of the magnetic field close to the cylinder shaped specimen.COMSOL program was used for modeling experiment results. Consequently, model results were compared to MR tomograph measured data. Changes of the magnetic field in space of xy cut of the specimen were integrated in both cases. Before integrating of the magnetic field changes was necessary to filter, unwrap and detect accurate position of the specimen. Magnetic susceptibility calculated from measured data is in comparison to theoretical value, as well as model value, slightly different. Difference of those values is lower than 5%. Due to the used model and measurement were extended principles of the NMR method for magnetic susceptibility measurement.
