Abstract

Nuclear Magnetic Resonance (NMR) systems with inhomogenous main magnetic fields, which are used to analyze material properties, have been developed before. Therefore, Magnetic Resonance Imaging (MRI) systems with inhomogenous main magnetic fields can be possibly developed to image tissues. To investigate the possibility of AM in inhomogenous main magnetic field, Magnenetic Resonance (MR) signal has to be analyzed. In this study, MR signal's parameters deviation due to inhomogeneity level change in the main magnetic field of a MRI system is investigated. Analyzed AM signal parameters are signal peak, energy and relaxation constant. Deviations of these parameters, because of inhomogeneity level change in the main magnetic field, are related to change in MRI system's properties. Thus, starting from the AM system's properties, tolerable inhomogeneity level in main magnetic field can be found.
