Abstract

Field inhomogeneity related phase errors in multi‐shot echo planar imaging (EPI) are directly visualized and analyzed in the spatial frequency domain data or β€˜k‐space’. The echo time shift (ETS) technique incrementally moves the position of the echo train and improves the phase error function by redistributing phase discontinuities away from the center of k‐space.

After an introduction to Fourier NMR imaging, the effect of magnetic field inhomogeneity on image quality is discussed. The field inhomogeneity leads to a distortion of the image when the reciprocal space is sampled on an oblique plane. This effect is especially strong in echo-planar imaging (EPI),
