A method for automatic correction of EPI trajectory errors is presented. The method is an iterative parallel imaging reconstruction which uses k-space data consistency to correct image artifacts. An advantage of the method is that it requires no calibration data and allows correction of non-static errors such as those due to gradient coil heating.
