Method for Magnetic Field Approzimation in MR Tomography

摘要：

This paper describes a method, which can be used for creating 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. In the end of my article is experimental solution of magnetic field and models of magnetic field created by Matlab.
