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 developed 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. The methods for analysing the phase MR image and measuring the magnetic susceptibility were tested on non-conducting samples of clay. They can be used in methods of medical MR diagnostics, in particular in cranial region, and to suppress errors in localizing ill tissues.
