Mapping and homogenity correction of basic magnetic field in tomograph
 Žůrek, Dalibor ; Kubásek, Radek (referee) ; Hadinec, Michal (advisor)
This work focuses on a search of available literature in the field of mapping the magnetic field and the degradation of the field gradients. Initially on introduction to basic concepts in the field of magnetic resonance imaging, which are important for understanding the problems and become familiar with the principles of measurement of magnetic fields on the selected surface. Furthermore, there are described two basic measurement techniques, magnetic resonance imaging. The work is analyzed the degradation patterns of magnetic field gradients using the Taylor series and spherical functions. The second part describes how to obtain readings in the tomograph, which together with the previous decomposition of the field then used to describe a numerical calculation of magnetic induction on the surface of a sphere. Values measured and calculated values are compared at the end.
