Original Abstract

The paper describes the possibility of modeling numerically the magnetic field deformations in the environment of the measured dia-/paramagnetic samples for the purposes of studying the MR images deformations owing to the susceptibility of heterogeneous materials (objects). Verification was realized using a simple sample configuration (circular plate), and the numerically modelled cross-sections were compared with the experimental measuring course of the magnetic field measured by the MR Gradient echo technique. The results show that it is possible - via a technical calculation - to determine the magnetic field deformation in the environment of complex-shaped or non-homogeneous structures in the MR experiments
