Abstract
In a method for measuring a gradient field in a magnetic resonance tomography (MRT) system, a first slice is excited by a first radio frequency (RF) pulse being emitted and by a first slice selection gradient being switched at least partly at the same time as the first RF pulse. A second slice is excited by a second RF pulse being emitted and by a second slice selection gradient being switched at least partly at the same time as the second RF pulse. The second slice intersects with the first slice in an intersection region. After the excitation of the second slice, a readout gradient is switched, and an MR signal emitted from the intersection region is acquired. Depending on the MR signal, a disruption variable is computed, which determines a deviation of a temporal course of an amplitude of the readout gradient from a predetermined required course.
