Abstract
AbstractA simple compensation concept for eddy currents generated by additional gradient pulses is presented. Similar to other pre‐emphasis schemes, the gradient pulse shape is overemphasized in the opposite way of the effect of the eddy currents to compensate for the deviations from the anticipated (rectangular) shape. In difference to other schemes no extra hardware is required, but eddy currents have been tried to be cancelled simply by a few short extra gradient pulses. The compensation can be done either by cancelling the amplitude of the eddy currents or their effect on the phase of the NMR‐signal. For certain conditions even analytical solutions can be found. The general treatment is validated by simulations and experiments.
