Abstract
Segmented echo planar nuclear magnetic resonance imaging is performed using an iterative correction method that corrects or suppresses geometric distortion in the image domain caused by off-resonance phase discontinuities in the phase encoding direction. The iterative correction method can be performed in a single scan by providing extra gradients in the pulse sequence to generate an extra transverse magnetization echo from the pulse. Additionally, the iterative correction method can be performed using a separate non-segmented double-echo scan in combination with data obtained using a conventional segmented echo planar imaging pulse sequence.
