Original Abstract

This paper describes a method, which can be used for creating spherical map of magnetic field . Method has a great usage in magnetic resonance tomography, when we need to get information about homogeneity and characteristics of magnetic field inside the working space of the MR tomograph. The main purpose of this article is to describe basic principles of magnetic resonance phenomenon and mathematical method of Legendre polynoms which can be used for signal processing of FID (Free Induction Decay) signal obtained from tomograph detection coils. Coefficients obtained from Legendre polynoms are used for magnetic field approximation inside desired working space of MR tomograph. In the end of article, there is an experimental solution of magnetic field and models of magnetic field created by Matlab.
