Method of acquiring eddy currents that are caused by switched magnetic field gradients of a magnetic resonance apparatus and that contain cross-terms

Abstract

In a method for acquiring eddy currents that are caused by switched magnetic field gradients and that contain cross-terms, at least the cross-terms can be determined from the selected slice within a short time, by the steps of introducing a spatially expansive phantom into the examination region of the magnetic resonance apparatus, activating a measuring gradient pulse that exhibits a prescribable pulse width, and after the deactivation of the measuring gradient pulse generating at least two imaging sequence blocks following one another at the spacings (t1, t2, tn) with at least two-dimensional, complex data set being generated from their imaging signals, the phase information contained therein being proportional to the magnetic field strength.
