Original Abstract

Electrically and magnetically conducting materials found in the human body cause major deformations in images obtained by magnetic resonance imaging (MRI). To study the deformations and to develop new MR methods with these deformations suppressed, a method for measuring magnetic susceptibility has been designed for samples that do not produce MR signals. In the paper, a method is described for processing the phase image being measured, in order to greatly eliminate systematic errors in the MR measurement of magnetic susceptibility and to calculate it.
