Abstract:
Techniques are disclosed for creating measurement data of an examination object by means of magnetic resonance technology in a plurality of repetitions according to a pulse sequence pattern, existing information about gradients that have already been switched is considered to determine compensation gradients that are possibly to be switched in a following repetition for compensating eddy current effects. Such dynamic determination and switching of compensation gradients make it possible to dynamically compensate eddy currents. Consequently, the image quality of image data reconstructed from measurement data acquired using inventive compensation gradients is increased.
