A common solution to correct for ghosting in interleaved echo planar imaging (EPI) is to employ echo time shifting (ETS). Although ETS corrects for ghosting in a robust, non-iterative, and automatic manner, it does so at the expense of increasing total scan time. In this work, a simple, yet effective scheme to increase the efficiency of ETS is proposed. Using the proposed technique, shorter scan times are possible when the in-plane resolution is fixed. Alternatively, the proposed scheme can acquire higher resolution images when total scan time is fixed.
