This work describes the implementation of the VAT methodology for EPI sequences as a means to eliminate in-plane distortions. Results demonstrate that a relatively long RF pulse, on the order of the duration of the total EPI readout period, is necessary to minimize image blurring. However, the reduced in-plane blurring is achieved at the cost of increased slice profile distortion.
