We propose a simple procedure for eddy currents correction based on a linear model for the distortions as a function of gradient amplitude. The model was first test on a tetradecane phantom and then applied to human brain. The procedure was demonstrated to improve the fit quality when a CHARMED data analysis is performed. Furthermore, the corrections can be combined with a model for motion-induced distortions to further improve the data quality.
