USE OF GRADIENT COILS FOR CORRECTING HIGHER ORDER BO FIELD INHOMOGENEITIES IN MR IMAGING |
摘要 |
<p>0 120The invention relates to a method of correcting higher order Bmagnetic field inhomogeneities in the examination volume of an MR device. According to the invention currents through two or more coil sections (X X) of at least one of a plurality of gradient coils (4) are independently controlled in such a manner that higher order field inhomogeneities of the main magnetic field B are compensated for by the magnetic field of the at least one gradient coil (4).</p> |
