Measurement of weakly magnetic material using new MR technique

Materials with different magnetic susceptibility can cause deformation of magnetic field in MR tomograph, resulting in errors in obtained image. Using simulation and experimental verification we can solve the effect of changes in homogeneity of static magnetic fields caused by specimen made from magnetic material in MR tomograph. This paper describes theoretical base and experimental measurement of new magnetic resonance imaging method for susceptibility measurement. This technique is suitable for substances with no signal in MR tomography. The method uses deformation of magnetic induction field in specimen vicinity. For MR purposes it is necessary to immerse specimen into reference medium with measurable MR signal (water is suitable).
