eng Abstract:
[eng][cze] In this work, we developed a method, which is used for approximation of basic magnetic field B0 inside a specific spherical volume. The coefficients of spherical function expansion obtained from approximation process can be used for determination of shimming currents which are feeding correction coils of tomograph. V práci je vyvinuta metoda využitelná pro aproximaci základního magnetického pole uvnitř sférických souřadnic. Koeficienty rozvoje sférických funkcí získaných z aproximačního procesu mohou být využity pro korekci pole v MR tomografu.
