The paper presents a mapping method, which is used to obtain boundary conditions on desired volume. The process of obtaining the magnetic flux density from NMR spectral characteristics is explained. The spherical functions are used for magnetic flux density approximation. The discussion of suitable degree and order for approximation is made. Then maps of magnetic flux density inside measured volume are computed. These maps are compared to measured phase images. Phase images are gained by mapping technique based on MRI methods. The comparison algorithm is made in Matlab and results are discussed.
